What are the commonly used cast iron rolls?

In China's current standards, cast iron rolls are divided into chilled cast iron rolls, infinite chilled cast iron rolls, ductile iron rolls and high chromium cast iron rolls four categories. Because of the composition, inoculation, cooling rate, heat treatment, etc., cast iron has formed a huge system. Various cast iron rolls have different arrangement structures and functions and can be used in different rolling mills.

What are the material characteristics of cast iron roll?

Aiming at the problems of difficult processing and low processing power of cast iron roll, this paper expounds the characteristics of cast iron roll, tool raw materials, machine tool function, processing technology and application, and clarifies the influence of tool selection, processing technology, machine tool requirements and roll application on the use of cast iron roll.

What is the classification method of cast iron roll?

(1) Alloy chilled cast iron rolls for alloy chilled cast iron rolls can form a white layer by developing the supercooling degree and surface cooling of molten iron. Is there any free graphite in the basic economic structure design of the roll body working layer? Metallographic analysis is arranged as fine pearlite and carbide, with high hardness and good wear resistance. Suitable for small bar, wire rod mills and narrow band finishing mills.

Contrast characteristics of hot-rolled ball mill steel ball and cast ball

In recent years, the domestic market is gradually introduced a new type of ball mill ball-hot rolled ball mill ball, it can be widely used in mining concentrators, thermal power plants, cement plants, refractory plants and other industries that need to use grinding machines. The hot-rolled ball mill steel ball has good quality, high cost performance, energy saving and environmental protection, and has been widely used by large foreign mining companies, and has gradually replaced the traditional casting ball. The research on hot-rolled ball mill is helpful to environmental protection and energy saving, improve the technological level, and improve the economic benefits of enterprises.

Function and Working Principle of Bending Straightening Machine

The equipment first uses straightening rollers to apply pressure to materials such as aluminum plates and aluminum strips, and extrude to change the straightness of the metal plates. There are usually two rows of straightening rollers with different numbers. The bending and straightening machine also has a two-roll straightening machine, which straightens materials of different diameters by changing the angle of the two rolls (concave in the middle and hyperbolic rolls). The main types are pressure straightening machine, balanced roll straightening machine, shoe roll straightening machine and so on.
