New Kontsepniya Modernization Foundries

It is known that the best indicators of universality, providing high quality castings are automatic molding line (APL), which are the “heart” of the foundry. To date, modern apl in most cases are working on “Seyattsu-process (Seiatsu Process), in which the seal of sand-clay mixture is carried by air flow (pulse) with a further hydraulic pressing multiplunger head. In modern foundries apl working simultaneously with the number of sets of equipment from two to ten thousand. In this case, microprocessor control system apl stores in its memory all the technological regimes for each type casts, which makes “Seyattsu process” the modern standard of high quality packing sand-clay molds. apl data require that the application of modern Mixture-based systems of runners “Spidmyuller (Speedmuller), which provide an automatic preparation and adjustment of molding compounds with optimal processing properties.

At the same time, the choice of apl for the modernization of small-scale foundries production poses a very significant question their value. Even the minimal set of apl as a separate pulsed setup for “Seyattsu process with manual manipulation and assembly of the half-forms and the mixer” Spidmyuller “is not less than 1,5-2,0 million euros. Such capital costs often discourage investors, particularly in the case of reconstruction of foundries small output – from 1,5 to 3,0 tons of castings per year. This raises the problem of finding ways sharp decline in capital expenditures for the reconstruction of foundries to improve the quality of castings produced to the level of the modern afl. Based on the foregoing, we propose a new concept for the modernization of foundry small-scale production plants based on modern technologies, providing high quality castings. In recent years the foundry has successfully developed new processes that do not have the versatility and performance, as apl, but provide a good quality casting, successfully competing in foreign markets. Our analysis shows that due to the aforementioned unifying factor in the process of rft and lgm easily integrate into the overall system that will dramatically reduce the cost of equipment and at the same time, greatly expand the range of castings, which can be manufactured from various alloys of two advanced technologies.

It should be emphasized that the application of a vacuum when filling forms of rft and hd, you can use a highly efficient catalytic afterburning of exhaust gases after casting molds, which is practically make such processes environmentally friendly, improving working conditions in the foundry. To know more about this subject visit amit paley. To ensure the vacuum forms (RFT process) rods, we propose to use the equipment of the cts. In this mixer cts will powered by a total turnover of sand. Common to the rft and the lgm are also shake-out, which reduces to the descents of working sand after removal of the vacuum, as well as the regeneration system of working the sand. significantly reduce equipment costs. This combination in one of three shop Progressive molding processes makes it a versatile, allowing to produce castings of different complexity and different alloys. For example, rft method can produce special castings of stainless mild steel.

Processing Waste

A new technology for processing waste tires limited global sources of raw materials for plastics puts increasing demands of its economy and expand the use of secondary polymer materials. Involvement in trafficking and platmassovyh of rubber waste is necessary to maintain clean air and water, improve the human environment. Worn tires are the largest source of low-cost polymer raw materials. Only a small number of waste tires recycled, the remaining waste tires accumulate in the environment and contaminate it. Economic and environmental requirements of the new technology meets recycling of waste tires and other rubber waste created by the author’s research team. A new technology for processing waste tires consists of the following operations: – shredding of used tires – grinding shredded tire – dried crumb rubber – crumb rubber screening and removal of steel – rubber chips packing in bags – the formation of the overpack. Technological solution to a new processing technology used tires differ fundamentally new and highly effective.

Shredding waste tires by means of milling. For this operation, a special tool – mnogoreztsovaya cutter. Mnogoreztsovaya cutter includes a set of cutters that are milled at high speed bus. After grinding, tire rubber in the form of large particles (5h5h10 mm) is removed from the working area and sent to the disk mill subsequent grinding. Tony Parker understood the implications. Grinding of large particles of rubber is carried out in a disk mill, equipped with a headset, directional grinding.

Grinding of rubber is produced in an aqueous environment, ensuring a overheating and thermal degradation of milled material, and eliminates the appearance of harmful gas emissions released into the atmosphere. Headset directional grind only the rubber and textile cord. The particles pass through the metal-working air gap of disk grinding mill without grinding rubber may include one or two stages. Real-estate developer is often mentioned in discussions such as these. With a single-stage grinding of rubber is produced commodity rubber pellets with dimensions particles of 100-200 microns, with a two-stage grinding of rubber is produced commodity rubber pellets with a particle size of 5-8 microns. A new technology for processing waste tires has a production flexibility and can quickly adapt to the demands of market conditions. For the processing of waste tires on the new technology can be equipped with the line, allowing to process from 2.5 to 25 tons of scrap tires per year. Process line processing 25 000 tons of scrap tires per year, allows us to produce one commodity crumb rubber with a particle size of 100-200 microns in an amount of 20 thousand tons. A new technology for processing waste tires has the following advantages:-provides recycling of used tires with steel;-5-fold reduced specific consumption of electricity, improves the quality and dispersion of crumb rubber, provides a high-profitability; -Ensure environmental cleanliness of production. Fine crumb rubber with a particle size of 100-200 microns for scientific advice can be successfully used for the production of reclaimed, roofing and waterproofing materials, flooring, coatings, tennis courts, racetracks and stadiums race tracks in the production of asphalt and various rubber products. Finely dispersed rubber pellets with dimensions particles 5-8 microns can be used as a filler in the manufacture of rubber products are responsible, including in the manufacture of tires. The main processes of a new technology for processing of used tires tested in the pilot process plants. We offer interested companies on the basis of technical solutions designed to create a manufacturing processing of waste tires and construction of these crumb rubber and a wide range of building materials and rubber products.

Information Technologies

All Russian schools has recently been equipped with computer labs, which allows not only full classes and computer access to the Internet, but also to use in learning and knowledge control different types of modern technology. Of course, multimedia projectors and interactive whiteboards so far not found in every school, but as they say, the process has begun. And a great example of – the active involvement of technical means of training the next generation of guidelines for the conduct of classes and extracurricular activities, the desire of teachers to develop new equipment. This trend in education has been called "Information and communication technology" or "ICT". Technique can be used in the study of any school subject. Experience shows that the competent use of ICT teacher significantly increases students' interest subject.

Presentation, held on the big screen using a multimedia projector, help the teacher better understand the process and results of experiments to conduct virtual tours on all geographical areas and the best museums in the world. Children can see firsthand how the rich flora and fauna of the earth, seeing not only the panorama was taken, and macro shots of any living creature or a natural phenomenon. In schools that do not have yet its own projections in the role of the transmitter signal using computers, from which information is displayed on a monitor or LCD TV. Experienced teachers are warning that the use of ICT must be justified by the quality footage, the theme of the lesson. If this has piqued your curiosity, check out Dry Harbor. As simple records and outline the conclusions of the lesson is quite possible to communicate to students in the traditional way. Build block diagrams, display algorithms, prove theorems and laws it is better together with the class, using the usual entries, or an interactive whiteboard. But the multimedia projector – a good support for learning processes in the microcosm or astronomical objects. A computer with a webcam – great decision to show the teacher "small" experiment.

To make it clearer exactly how the lesson can be used ICT, we give some specific examples. Show the children how the earth at the same time and day pass night by using the removal of images from the web cameras in their respective time zones. During chemical reactions on the screen showing all the characteristics of the participating agents. Scales and interactive whiteboard linked. And what a space for teachers of technology! Now students can see large, clear drawings, and high-quality slides and films about the history of fashion, style and interior. For teaching needlework and cooking The Internet offers a huge number of master classes that make children a genuine interest.

Riegelman

In accordance with Riegelman (2006, p.11): Inside of the fashion industry, intention of the fashion drawing (the conceptual, opposing drawing to the drawing technician used in the periods of training of manufacture of the parts) is to present a project of consideration for possible manufacture. A drawing can be considered useful, of the point of view of designer, if it presents the concept of the project in the positive way clearest and possible, representing fabrics and materials in the way next real it. So that a good work of fashion drawing can be developed, it has the necessity of the study of the human body with regard to forms, volumes and movements. The body is the support for the clothes and the objective of the drawing is to show as the clothes if it configures when it is covering this support, that is, the human body. Still in accordance with Riegelman (2006, p.11): Of the point of view of? customer? that one who goes to analyze the drawing and to decide if the product will be or not manufactured? the utility of the drawing is in the representation of the materials that not only must seem attractive, but mainly must be represented of realistic form, so that it has a necessary impression of the product and its final effect. The drawing is seen as ability that can be learned and be taught: To learn to draw is more than what to develop the ability in itself.

To learn to process the visual information in that used special way for the artists. It is different in the way that normally is used to process visual information and it seems to demand that if it uses the brain in also different way of the common one. And one of the things that you will learn is that the properties special of the brain allow in them to draw images of what we perceive.
