Different Types of Rolling Roll Mills used by Steel Roll Manufacturers

The rolling process is the most common industrial process, which is used for making large length cross section like sheets and plates of steel and aluminum for structures. Rolling mills are used for completing the rolling process. These are available with various steel roll manufacturers in a variety of shapes and sizes as per requirement of the […]

Metallurgy of Rolling mill Rolls


Rolls are implements or tools used in rolling mills to reduce the cross section of the material being rolled. They are highly stressed tools and are subject to wear. They are needed both for the rolling of sectional as well as flat products. In recent past, rolling technology has improved and changed dramatically, but the […]

Mill Roll classification summary

Classification of pressed metal types Rolling steel products are called black rolls. Rolling non-ferrous metal materials (copper, aluminum, etc.) products are called non-ferrous rolls.   According to the temperature of the rolled material when it is rolled The rolling temperature higher than the recrystallization temperature of the rolled material is called hot rolling, and the corresponding roll […]

Determine the type of rolling mill and its layout

Principles of rolling mill selection The main basis for the selection of the rolling mill is the steel grade, product variety and specification, the size of the production scale and the product production process determined by the workshop. When choosing a rolling mill, generally pay attention to the following principles: 1) Under the premise of […]

HSS ROLLS Material

The high-speed steel roll material contains high alloy elements such as vanadium, tungsten, chromium, molybdenum, niobium, etc. The types of carbides in the roll structure are mainly MC type and M2C type. Compared with ductile iron rolls and high-nickel-chromium rolls, the single-groove (time) steel passing is higher, which saves roll changing time, improves rolling mill […]
