Treatment, rolling and deformation of the zinc
The company Electrocentury-steel offers affordable procurement price of zinc, which fully comply with the requirements of GOST 3640−94. The supplier ensures prompt delivery of products to any place specified by the consumer.
General technological characteristics of zinc
Zinc is a low-plasticity metal, so the workpiece for further processing is obtained by casting or hot rolling. The smelting of zinc is carried out at a temperature of 440…4800 C and hot deformation — at 150 to 2000 C.
During rolling of zinc only receive a rolled metal sheet, strip, tape, foil. In the future they can be used in the absence of significant mechanical loads. In the modern metallurgical production is also used combined treatments of zinc and its alloys. Their essence lies in the fact that the sheets and strips produced from the cast metal with the technology of continuous casting or a method of combining continuous casting with rolling.
The company Electrocentury-steel proposes to implement a rolled sheet of zinc of various thicknesses and dimensions at economical price from the manufacturer. The provider ensures efficient transportation of the metal at any point, wasany by the customer.
Features of rolling zinc
Since in the initial state, zinc has a pronounced coarse grain structure, when hot rolling ingots or billets obtained by semicontinuous casting, compression is produced with a small degree of deformation that does not exceed 8…10%. Otherwise, the observed cracking of the original blanks.
On subsequent transitions of hot rolling cast zinc ductility of the metal increases because the cast structure is transformed into strain, with the characteristic small grain size, which is elongated along the axis of rolling. With increasing number of passes at temperatures of 150…2200 With the ductility continues to increase, reaching 40…50%.
Zinc has a strong influence of the thermal effect of deformation, therefore, in subsequent passes the initial temperature of the rolled metal increased by 50…700 C. This affects the processes of hardening/softening of zinc. Therefore, in the temperature range 50…1000 C, a deformation of the zinc is already incomplete hot.
The peculiarities of the processing of zinc have a significant influence on the final mechanical properties of rolled sheets, which should be considered when assigning the modes, post-processing of semi-finished products and workpieces made of the metal.
Buy rolled billets and semi-finished products of zinc at affordable prices from manufacturers, the company offers Electrocentury-steel. Provider ensures timely delivery of metal to any destination specified by the customer.
