Description
The wear-resistant steel plate produced by our company contains a certain amount of carbonized chromium, which is the most important hard phase in the wear-resisting steel plate. It has the following characteristics:
Chromium carbide (Cr3C2) have lower melting point 1710 ℃, the density of 6.68 g cm - 3, thermal expansion coefficient of 10.3 * 10-6 K - 1 (20 ℃ ~ 1200 ℃), 19.1 W, m - 1, the thermal conductivity K - 1. Main feature is the hardness of chromium carbide at room temperature and heat is very high hardness, good wettability and C0, Ni and other metal, the highest antioxidant capacity in the type metal carbides, in 1100 ℃ ~ 1400 ℃ in air to severe oxidation, good corrosion resistance superior. It is an excellent combination of high temperature oxidation, friction wear and gas erosion resistant materials. It is mainly applied to high temperature coating, but direct coating of carbonized chromium coating is not strong adhesion. Therefore, it is mainly used for the preparation of the main components of Ni cr-cr3c2 composite powder.
Leading sizes:1500*3000, 1450*3450, etc
Leading thickness:6+4,8+5,10+10,20+12,20+20 etc
5+3,6+4,8+5 chromium carbide plates are usually used in some cement industries.10+10,12+12,20+12,20+20,these chromium carbide plates are usually used in mining companies.
base materials of the chromium carbide plate:Q235/Q345
Performence
1、Good impact resistance
Wear-resistant composite steel plate using low carbon steel or low alloy, stainless steel and other tough as the base material, the material of the metal not only has good wear resistance, but also can withstand the impact and wear in the process of conveying from a high fall and so on.
2、Better heat resistance
Alloy wear-resistant layer in the production process added vanadium, molybdenum and other alloy materials, so it can be used and worn at a high temperature of ≤ 800 ℃. Compared with the ordinary carbon steel substrate can only be used below 380℃, low alloy heat resistant steel plate is working below 540℃. This shows how high the heat resistance coefficient of the wear-resistant plate is.
3、Good corrosion resistance
The wear-resistant plate contains a large amount of metallic chromium, so it has good rustproof and anti-corrosion properties. It is especially suitable for the use of coal fall barrels and funnels. It is not only solid and firm, but also can prevent sticking coal.
The role of the lining plate
1. It is to protect the inner wall and end cover of the mill barrel from being worn by the grinding body
2. To enhance the stiffness of the cylinder to a certain extent.
3. Adjust the motion state of the grinding body, so that the energy obtained by the grinding body in the running process of the mill can be reasonably utilized. As in a bin mounted step lining board or batten lining board
The lifting height of the large grinding body can be increased, so that the grinding body can crush the material with greater kinetic energy. The corrugated lining board or flat lining board can be installed in the fine grinding bin to make the grinding body
The effect is enhanced.
4, the classification lining plate can make the steel ball in the bin according to the size of the ball diameter along the axial direction of the mill for positive classification, so that each diameter of the steel ball in the grinding process to play a full role.
