Surfacing Wear Plate Compared with many wear-resistant materials, wear-resistant composite steel plate has its irreplaceable and significant features:. 1. Surfacing wear-resistant plate; high wear resistance
Surfacing Wear Plate Compared with many wear-resistant materials, wear-resistant composite steel plate has its irreplaceable and significant features:.
1.Surfacing wear-resistant plate; high wear resistance
The chemical composition of the alloy layer contains 4~6% carbon and 25~30% chromium.The volume fraction of Cr7C3 carbide in the metallographic organization is greater than 45%, and the macro hardness is HRC56~62. The hardness of chromium carbide is between HV1400~1800, which is higher than the due time hardness in sand and stone. Due to the vertical distribution of carbides along the wear direction, the wear resistance is more than doubled compared with casting alloys with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows.
(1) With mild steel; 20 to 25.
(2) With high manganese steel; 5~10.
(3) With tool steel; 5~10.
(4) With cast high chromium cast iron; 1.5~2.5:.
2. Surfacing wear-resistant plate; good impact resistance
Wear-resistant composite steel plate bottom layer is low carbon steel or low alloy. Toughness materials such as stainless steel show the superiority of bimetallic. The wear-resistant layer resists the abrasion of the wear medium,. The substrate withstands the load of the medium and therefore has good impact resistance. It can withstand impact and abrasion such as high level drop hopper in material conveying system.
3. Surfacing wear-resistant plate; good heat resistance
The wear-resistant layer is recommended to be used at ≤600℃. If vanadium, molybdenum and other alloys are added to the alloy layer, it can withstand high-temperature wear at ≤800℃. Recommended temperatures are as follows: ordinary carbon steel substrate is recommended for use at a temperature of not more than 380 ℃; low alloy heat-resistant steel plate (15CrMo, 12Cr1MoV, etc.). The substrate is recommended to be used at a temperature not higher than 540℃. Heat-resistant stainless steel substrate is recommended to be used at a temperature not higher than 800℃.
4. The alloy layer of the composite steel plate with good corrosion and abrasion resistance contains a high proportion of metallic chromium,. Therefore it has a certain degree of rust and corrosion resistance. Can be used for coal chutes and funnels,. Prevent sticking coal.
5. Strong applicability
Wear-resistant composite steel plate has complete specifications and many varieties. Has become a series of commodities. The thickness of wear-resistant alloy layer is 3 ~ 20 mm, and the minimum thickness of composite steel plate is 6 mm, with unlimited thickness. Standard wear-resistant composite steel plate can be supplied with 1200 or 1450 x 2000 mm, and can also be customized according to the user's requirements according to the size of the drawing. Wear-resistant composite steel plate is now categorized into three types: ordinary type, impact-resistant type and high temperature-resistant type. Ordering high temperature wear-resistant and impact-resistant composite steel plate should be specified.
6. Convenient processability
Wear-resistant composite steel plate can be cut, leveled, punched, bent, curled, and can be made into flat plate, curved plate, conical plate, cylinder. The cut composite plate can be welded into various engineering structures or parts. The composite plate can also be heated and pressed into complex shapes with molds. Wear-resistant composite steel plates can be bolted or welded to the equipment for easy replacement and maintenance.
7. High cost performance
Although the manufacturing cost of wear-resistant composite steel plate has been increased, the service life has been increased several times, which greatly reduces the maintenance cost and downtime loss, and its cost-effectiveness is about 2~4 times higher than that of ordinary materials. The larger the material handling capacity, the more serious the wear and tear of the equipment, the more obvious the economic effect of using wear-resistant composite steel plate.
