PRODUCTIONS
The entire production of the plant is made directly on Mettek Steel. In addition to rolling mills and production of calibrated products, the factory has its own steelmaking that ensures product quality throughout the production chain.
Mettek Steel Production Process
Steel Smelting
Our steels are produced by melting recyclable metallic scrap. During the melting process, the specified chemical composition is always controlled and, if necessary, corrected by adding alloying components.
Continuous casting
When the steel reaches the required temperature and chemical composition, a ladle containing the molten metal is conveyed to the continuous caster. As it passes through the continuous caster, the molten steel gradually cools and solidifies in the form of a commercial square billet.
Hot rolling
The continuously cast billets are heated to a temperature of about 1150°C in a pusher furnace and then formed as required on the rolling mill. The entire forming process consists of several stages which are implemented by a series of successive rolling.
Cold rolling
In this production step, the hot-rolled material serves as a semi-finished product for further forming, which, in contrast to hot rolling, takes place at room temperature. The advantages are a higher precision of the geometry as well as a higher quality surface of the product.
Cold drawing
Similar to cold rolling, hot rolled material is the starting product for drawing. The pre-profiles are drawn through a high-strength tungsten carbide matrix and thus formed in cross-section. Depending on the complexity of the geometry, up to eight drawing steps may be necessary. Forming is carried out with the addition of lubricants to reduce the high drawing forces.
