U92 coal cutter
Coal cutter, gear sets , tooth Block , U82, U84, U85, U92, U94, U95, U47, U765, U76, U119, U138, C31, S100, S120, S150, S160, S170, 75C, B47K22, 3050, C31HD, C21HD, 13 #, 23 #, 55 # , etc. complete model specifications , high strength, wear resistance and long life . This product is heat-treated steel body use high-strength alloy steel, shaped to maintain a high toughness and high wear resistance ; heads through hot isostatic selection of high quality carbide . Widely used in a variety of mechanized mining machine, mechanized excavation machines, continuous mining machine . According to the different rock, half coal production performance of different design cutter, to meet different needs of customers . While the design , production, maintenance boring cannon head , shearer drum .
二、Coal mining machinery cutter is wearing parts , the company through long-term coal cutter analysis and research , the selection of new coal pick , coal pick cutter layout and structural improvements , and several other aspects of the coal pick a reliable was analyzed . Improve the reliability of the coal cutter , reducing consumption of coal cutter unit cost attributable to the proportion of effective working time to improve shearer .
三、Coal cutter uses: mainly used in coal mining and roadway, tunnel, ditch excavation of these works on the ground. Mainly completed with Shearer, boring machines, milling machines and other equipment. Coal-cutter model is mainly based on the hardness of coal mining, coal cutter teeth divided factors such as model, cutting teeth are divided into: U62,U47, U82, U84, U85, U82, U92, U94, U95, S100, S120, S135, S150, S160, S170 model, such as special models of quantitative production. Coal-cutter dental unit selection of heat treated high strength alloy steel, maintaining high strength and high toughness and high resistance to wear; all spring for high strength spring steel production, wear resistance is excellent. Isothermal quenching process of coal cutter head, hardness is not reduced. YG13C of cemented carbide using the regular factory production, quality and stability. Plus welding wear-resisting layer according to customer needs. Hardness reach 65 degrees.
四、Coal cutter advantages: 1, long life, is a traditional coal cutter 1-1.5 times. 2 high efficiency: an old-fashioned coal-cutter 2.5 times. 3, good energy efficiency: replacement number dropped substantially, shortens the downtime for coal, reducing the cost of extraction. Production quality standards: Parts a, cone hardness: hardness of HRC>65B, cutter rod: HRC28 °-32 ° c, Surface hardness: HV>2000 using a special heat treatment process, 40-45, basic non-oxidation
