Coal mill lining plate has good impact resistance when used, its wear-resisting composite steel plate is low carbon steel or low alloy, when used stainless steel and other ductile materials reflect the advantages of bimetal, wear layer resistance to wear medium wear, the substrate bears the load of the medium, so it has good impact resistance.It can withstand the impact and wear of high drop hopper in the material conveying system.
Coal mill lining board has good heat resistance, wear-resisting layer is recommended to use when operating 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.Recommended temperature is as follows: ordinary carbon steel substrate recommended is not higher than 380 ℃ condition of use;Low alloy heat-resistant steel plate (15 crmo, 12 cr1mov, etc.) recommended base plate is not higher than 540 ℃ condition of use;Heat resistant stainless steel substrates recommend used at not higher than 800 ℃ condition.
Coal mill liner generally good corrosion resistance of wear resistant composite steel plate alloy layer will contain a high percentage of metal chromium, it has a certain rust and corrosion resistance.It can prevent coal from sticking when used in coal chute and funnel.
Applicability of strong wear-resistant composite steel plate specifications, varieties, has become a series of goods.The thickness of wear resistant alloy layer is 3~20mm.The thickness of the composite steel plate is 6mm at most, and the thickness is not limited.Standard wear-resistant composite steel plate can be provided with 1200 or 1450 2000mm, or according to user demand, according to the size of the drawing customized processing.Wear-resisting composite steel plate is divided into three types: ordinary type, impact type and high temperature type.www.wuxiorient.com
