High Speed Steel roll has a high hardness and outstanding wear-resistance in high temperature, by controlling the chemical composition and heat treatment process, the hardness of working layer of roll barrel can reach 75-95HSD, there is complex carbides of vanadium, wolfram, niobium, molybdenum in matrix of martensite, which commits homogeneous hardness throughout the working layer, and even wear in grooves. Chemical composition
Alloy Indefinite Chilled is cast iron with fine inter-crystalline graphite evenly distributed throughout the working layer of roll barrel.The sizes, shapes and distributions of graphite and carbide are controlled by the chilling effect and the contents of alloy elements.The addition of alloy elements such as Mg,Ni,Cr,and Mo changes the matrix from pearlite and bainite to martensite. Plus the present of small amount of fine graphite, the performance of spalling resistance, thermal crack resistance and wear resistance were enhanced significantly. The material has small hardness gradient in the working layer of roll barrel and is suitable for intermediate and finishing stands for bar,wire and section mills.
The character of graphite steel roll is similar to that of adamite roll. The main character is that it contains a small amount of fine graphite in its micro-structure, which increases its resistance to fire-crack and prevent oxidized scales from adhering. Thus making it suitable for blooming and roughing stands.
Alloy steel formed by adding some alloy elements into the common carbon steel, through heat-treatment process, the good performance of wear-resistance and toughness can be achieved. It is widely used for backup/roughing roll for plate/strip mill and backup
roll for leveling mill, Roughing roll for plate/section/bar & wire-rod mill; Break-down roll for rail beam/universal section mill; Descaling/roughing/backup/vertical roll for strip mill.
High chrome steel contains a lot of Cr, Ni, Mo and other alloy elements in the liquid metal. When the liquid metal solidifies, the carbide precipitated in the matrix structure is M7C3 eutectic carbide, , so it has good wear resistance.

Paper-making cots are cots used for papermaking. According to the structure, they can be divided into smooth roll (flat roll, no pattern on the surface), groove roll, screw roll, vacuum roll, movable arc roll (hollow bending roll) and medium high roll. It is used in different parts of the paper machine to squeeze water, press and polish.

It is used in different parts of the paper machine to squeeze water, press and polish. A long net paper machine usually has 70 or 80 rubber rollers of different sizes. According to the structure, it can be divided into smooth roll (flat roll, no pattern on the surface), grooved roll (groove on the surface of the coating), threaded roll (thread groove on the surface of the coating), vacuum roll, movable arc roll (hollow bending roll) and medium high roll. It is used in different parts of the paper machine to squeeze water, press and polish. Generally, it is made of various Sr (such as PU, etc.).
