Hss Rolls

Adamite rolls and rings are performance steel rolls with an optimum combination of wear and fire-crack resistance. This quality has a short range of carbon content, plus varying quantities of Nickel, Chromium and Molybdenum to achieve higher hardness levels. It can be produced either by the Static Monoblock conventional method, or by the horizontal Centrifugal Cast method.

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.

These kind of rolls are mainly for grain and oil, foodstuff, with special alloy content in white iron and grey iron, makes it good for applications, our manufacturer has participated in grain rolls standard drafts and compiles, which has good experience and high cost performance.

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. Papermaking 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. 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.).

SGA rolls are widely used in intermediate stands and finishing stands, due to it's stable quality, and better strength, toughness and wear resistance. In normal steel rolling process, it has no rolling accident, no breakage, in most of severe situation, mills used for replacing AIC rolls.

Graphite Steel (GST) 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.

Adamite is a material that has both high strength and toughness of cast steel and good wear-resistance and hardness of cast iron. Due to its alloy elements such as Si, Ni, Cr, Mo etc, and some amount of carbides in the matrix, through a certain of special heat treatment technology, making it has a good wear-resistance and toughness. AD roll also has small amount of hardness drop and deep cutting depth.
