Chute liner

Chute liner
Henan sebon industrial co., LTD is a professional manufacturer of wear-resisting lining board, with advanced production technology. Sebon wear-resisting lining board products are sold at home and abroad, by the broad masses of the user's consistent high praise.
Wear-resisting lining board, is refers to the wear resistant steel plate through cutting, plate bending deformation, punching, and welding production process, such as all kinds of wear resistant lining board, such as conveyor lining plate, coal feeder plate/inverted cone cyclone separator and blade plate, wear-resisting, etc., wear-resisting over 15 times life span than ordinary steel plate. Wear-resistant steel plate is in ordinary steel and heat-resistant steel, stainless steel plate on welding form is given priority to with Cr7C3 carbide volume fraction greater than 50% of the alloy wear-resisting layer.
Wear-resistant steel with high abrasion resistance, impact resistance, deformation and welding performance, can be crimped as directly as steel plate, such as cutting and punching processing, processing into engineering parts wear to meet industrial and mining.

Compared with a number of wear-resisting material, wear-resistant composite steel plate has its irreplaceable significant characteristics:
1, high wear-resistant carbon content in the chemical composition of the alloy layer of 4 ~ 5%, the chromium content up to 25 ~ 30%, the microstructure of Cr7C3 carbide volume fraction of 50% or more, the macro hardness HRC56-62, the hardness of chromium carbide is HV1400 ~ 1800, higher than the hardness of quartz sand in HV800 ~ 1200. Because carbide into the vertical distribution of the direction of wear, even with the same composition and hardness of the casting alloy, wear-resisting performance is more than double. Compared with several kinds of typical material abrasion resistance is as follows:
(1)with low carbon steel; 20 ~ 25:
(2)with high manganese steel; 5 ~ 10:
(3) and tool steels; 5 ~ 10:
(4) and as-cast high chromium cast iron; 1.5 ~ 2.5:
2, good impact resistance: the ground floor of the wear-resistant composite plate is low carbon steel or low alloy. Ductile material such as stainless steel, and demonstrate the superiority of double metal, wear-resisting layer medium resistance to wear of wear and tear, substrate under medium load, therefore has the good resistance to impact. Can withstand conveying system under high impact and abrasion head hopper, etc.
3, good heat resistance, wear-resisting layer is recommended to use under the working condition of 600 ℃ or less use, if adding vanadium alloy layer, such as molybdenum alloy, can withstand the high temperature of 800 ℃ or less wear and tear. Is recommended to use temperature as follows: ordinary carbon steel base board recommended is not higher than 380 ℃ condition of use; Low alloy heat-resistant steel base board (15 crmo, 12 cr1mov, etc) recommendation is not higher than 540 ℃ condition of use; Heat resistant stainless steel base board recommended which used in working conditions is not higher than 800 ℃.
4, good corrosion resistance, wear resistance of composite steel plate contains a high percentage of metal chromium alloy layer, so it has some rust and corrosion resistance ability. Used for coal cylinder and hopper, etc can be done to prevent caking coal.
5, strong applicability wear-resistant composite steel plate specifications complete, many varieties, has become a commodity series. Wear resistant alloy layer of 3 ~ 20 mm in thickness. Composite steel plate thickness is 6 mm, the thinnest thickness of unlimited. At present, the standard wear resistant composite plate can provide 1200 or 1450 x 2000 mm, can also according to customer requirements, size make to order according to the drawing processing. Wear-resistant composite steel plate is divided into common type, impact resistance and high temperature, composite steel plate to order high temperature wear resistance and impact resistance.
6, convenient processing performance of the wear-resistant composite plate can be cut, leveling, punching, bending and crimp, it can be made into flat, arc, cone plate, cylinder. Cutting good composite board can welding into various engineering structures or components. Composite panels can also be heating tools were compressed into complex shapes. Wear resistant composite steel plate can be fixed by bolts or welding on the device, convenient replacement and maintenance.
7, high price performance ratio of wear-resistant composite steel plate material costs increase, but several times to improve service life and greatly reduce maintenance costs and downtime loss, its price performs about 2 ~ 4 times higher than ordinary materials. Material processing, the greater the equipment wear more serious factories and mines, more obviously when using the economic effect of wear-resistant composite steel plate more obvious.
