Metal rolling mills are widely used in all aspects due to their superior performance. Our common automobile plates, bridge steel, boiler steel, pipeline steel, rebar, steel bars, electrical silicon steel, galvanized steel, tinned steel, including train wheels, are all processed through steel rolling.

What is the use of a metal rolling machine?

A metal rolling mill is a complete set of machines and equipment for parallel processing and rolling of metal balls, rolling is generally divided into cold rolling and hot rolling, so rolling mills are divided into cold rolling mills and rolling mills But the general rolling mill is based on the arrangement of the rollers. Number classification. The metal rolling mill mainly rolls the unformed metal blanks into the necessary metal material such as pipes and sheets. The sheet is rolled using cylindrical, curved, fan-shaped, conical parts, etc. General equipment for bending, shaping, and grinding of sheet metal.Used in shipbuilding, chemical industry, boilers, water and electricity, pressure vessels, and machinery manufacturing. Metal rolling mill is widely used in various industrial fields.

What is the working principle of a metal rolling mill?

Hot rolling is a metal processing process that occurs above the recrystallization temperature of the material. In the process of processing, after the grains are deformed, the grains recrystallize, which maintains an equiaxed microstructure and prevents the metal from hardening during cold work. The starting material is usually a large piece of metal, such as semi-finished castings, slabs, billets, and billets. If the raw material comes from continuous casting, the raw material is usually sent directly to the rolling mill at the appropriate temperature. For smaller production scales, the raw materials start at room temperature, so they must be heated.

Larger metal rolling mills are heated in a soaking furnace fueled by oil, gas, or natural gas, and smaller metal rolling mills are heated in an electric induction furnace. When the raw material is heated in the furnace, its temperature must be monitored to ensure that the temperature of the material is higher than the recrystallization temperature of the metal material. To ensure a certain safety factor, it is defined that the heating temperature of the raw material must be above the recrystallization temperature; this temperature value is generally 50 to 100 ℃ higher than the recrystallization temperature.

Hot-rolled metals generally have almost no directionality in terms of their mechanical properties and residual stresses caused by deformation. However, in some cases, non-metallic inclusions will transmit some directionality, and metal rolling mills less than 20 mm thick usually have some directionality. In addition, non-uniform metal rolling mill can cause a large amount of residual stress, which usually appears in shapes with non-uniform cross-sections, such as I-beams. There is an oxide scale on the surface of the metal rolling mill, which is an oxide formed at high temperatures. Usually by pickling or surface cleaning surface process to remove oxide scale.

 

What is the meaning of metal rolling mills?

Hot-made low carbon steels have a higher carbon content than cold steel sheets and blacksmiths seem to have a harder time managing the quality of the metal rolling mill In addition, for similar metals, the cost of hot-rolled products is generally lower than that of cold-rolled products.

Hot rolling is mainly used to produce sheet metal parts or products for simple business documents like railroads, other general uses for hot rolled metals are truck chassis, automobile wheels, pipes and hoses, water heaters, farm equipment, belts, stamping, compressor housing, railway equipment accessories, rollers, structural metal structures, railroad guardrails, cars, doors, machine tools, CDs, guardrails car body, clutch plates.

 

The continuous metal rolling milll adopts a complete set of the advanced automatic control system. The production process and operation monitoring of the whole line is controlled and implemented by the computer. The metal rolling mill is rolled on several rolling mills at the same time. ChaoLi Company has worked for several years to meet the need of customers from the food processing industry, steel production, and so on.
