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.).
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
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.

Chilled cast iron contains almost no free graphite in the matrix of working layer of the barrel. The microstructure is fine pearlite and carbides. It has a high hardness and excellent wear resistance. It is suitable for finishing stands of light bar and wire-rod rolling mills and narrow strip mills.
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.
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 Cr iron 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 80-85HSC, 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.
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.

The Oil casing is used to support the well bore of oil and gas wells to ensure the normal operation of the whole well after drilling and completion. Each well should use several layers of casing according to different drilling depth and geological conditions. Cement cementing is used after casing goes down. It is different from tubing and drill pipe. It can not be reused. It belongs to disposable consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well tubes. Casing can be divided into: conduit, surface casing, technical casing and reservoir casing.

5052 aluminum sheet and coil have good workability, high fatigue strength and good weldability. It has very good corrosion resistance, especially in marine environments. 5052 aluminum sheet can be anodized to improve the corrosion resistance of the material in corrosive environments.
Alloy 5083 aluminum sheet have higher strength than 5052 plate and has exceptional thermal conductivity. In the tempered condition, it retains good formability due to excellent ductility. It is highly suitable for welding and can be hardened by cold work. Because Alloy 5083 exhibits excellent resistance to general corrosion, it is used in marine applications. Since alloy 5083 aluminum sheet is capable of withstanding extremely low temperatures without brittleness or loss of properties, it is especially suited to the cryogenic market.
