机电修配厂试制了 ZQAL9—4铝铁青铜材料。该材料的机械性能:b=59.96kgf/mm~2,δ=42%,Ψ=27.75%,HRC=135;化学成份:AL=9.3,Fe=3.5;金相组织等均符合国家标准。该材料现已正式生产。第一批产品已在露天矿电铲上使用。 (杨世省)低合金白口铁耐磨材料,是机电修配厂技术科与铸铁车间共同研制的新型耐磨材料。该材料冲击值为 ak=0.3kge/cm~2,化学成份、金相组织(以珠光体为基体碳化物分布均匀)均符合设计要求。工业性能试验将在百花岭选矿厂和卅亩地选矿厂进
Mechanical and electrical repair factory trial ZQAL9-4 aluminum bronze material. The mechanical properties of the material: b = 59.96kgf / mm ~ 2, δ = 42%, Ψ = 27.75%, HRC = 135; chemical composition: AL = 9.3, Fe = 3.5; The material is now officially produced. The first batch of products have been used in surface mining shovels. (Yang Shi Province) low-alloy white iron wear-resistant materials, is the mechanical and electrical repair shop technology and cast iron workshop jointly developed a new type of wear-resistant materials. The impact value of the material ak = 0.3kge / cm ~ 2, chemical composition, microstructure (pearlite matrix carbide distribution) are in line with the design requirements. The industrial performance test will be carried out at Baihualing Concentration Plant and Xihu Mudi Concentrator
