The main purpose of heat treatment of steel, is to change its properties. Thanks to the heat treatment of steel acquired properties such as ductility, toughness, strength, endurance, and others. Heat treatment were divided into: 1. annealing. Annealing of steel used in cases where it is necessary to obtain a uniform structure. The annealing process involves three successive stages, firstly, heating steel to a predetermined temperature, Secondly, exposure of steel at a given temperature, and thirdly, slow cooling in the furnace. There are two kinds of annealing.

Upon annealing a second kind of changes depending on the phase transitions are observed. When annealing the 2 nd kind of steel acquires the equilibrium structure. 2. quenching. Tempering – a heat treatment of steel, which results in the steel with the maximum non-equilibrium structure and with an abnormal level of properties. Quenching process proceeds in three consecutive stages: the first stage – is heating steel to a predetermined temperature, the second stage – an extract of steel at this temperature, the third stage – the rapid cooling of steel.

3. vacation. Breakfast – a type of heat treatment steel is to reduce internal tension steel. 4. normalization. Normalization – a method of heat treatment consisting in heating the steel to the required temperature, then the exposure began, and then cooling the steel in air. To carry out the correct heat treatment of steel and produce the desired results, but also to determine the correct heating temperature, cooling medium and the type of equipment is necessary to clearly define the type of machined steel. When you select a brand of metal that of the item, you should pay attention to the operational and technological properties of steel. Given the brand of steel tempering temperature is determined range from 530 to 1300 C. To determine the heating temperature using a special device called a pyrometer. A cooling medium can serve as a furnace, air cooled, and others may occur gradually or immediately. Thus, the heat treatment of steel (metal) means the processing of products with thermal effects for changes in the structure and properties of the product in the right direction.

Stacker – a device that can be seen at almost any moment. Stacker is designed to carry cargo and put them on the shelves a great height. A related site: Sam Jones mentions similar findings. Without this device will store the goods simply impossible. There are various models of stackers, which are designed to work in different conditions. According to the design of any reach truck is a mobile device with a mast on which the up and down moving fork – for them and fits in the cargo pallets. Controlled forklift operator, and powered, in most cases from the battery.

The easiest Stacker – a device that the operator manually carries on warehouse, as the cart. To raise with it a fairly heavy loads using hydraulic or electric drive. This stacker – the most compact and maneuverable, it is very convenient when working in small spaces where the aisles between the shelves are narrow and more bulky equipment there to turn. However, to transport cargo over long distances, using a hand pallet truck, it is inconvenient and time consuming. Its use in large warehouses is unprofitable. Better means of handling and moving goods on a warehouse – is self-propelled electric pallet truck. He moved to the premises by an electric motor, and the operator is placed on a special platform. Thanks This increases the velocity of the stacker, the work becomes more efficient and productive.

However, this is not enough to transport goods in warehouses of a large area, which uses high racks (about 10 meters). For such objects created special stacker – reach trucks. They are installed retractable mast, which would push shipments even to such a height. Reach trucks (high-rise stacker) equipped operator cabin, so It is convenient to travel long distances, carrying goods with good speed. Compared with other types of stackers, reach trucks is undoubtedly the most powerful device, but its application is impossible to close warehouses because of the large size.
