23MnNiMoCr54钢是制造高强度圆环链链条的主要材料,原材料为退火状态,经过编环-焊接-调质热处理后制成煤矿运输机械高强度圆环链链条。根据圆环链链条的使用状态,对原材料的化学成分、组织均匀性、硬度均匀性、力学性能提出了相应的严格要求,以满足矿用圆环链用钢对下料、弯曲、焊接等工艺性能的要求。23MnNiMoCr54钢是德国牌号,在20世纪80～90年代以前主要依靠从国外进口,从20世纪90年代以后,国内有钢厂按德国牌号成分要求进行小批量试制,但是,尽管成分和日本生产的钢材相近,用国内的
23MnNiMoCr54 steel is the main material for manufacturing high-strength circular chain, the raw material is in an annealed state, and is made into a high strength circular chain chain of coal mining machinery after being braided, welded and tempered and tempered. According to the state of use of the circular chain chain, the chemical composition of raw materials, the uniformity of the organization, hardness uniformity, mechanical properties put forward the corresponding stringent requirements to meet the mine ring chain steel cutting, bending, welding and other processes Performance requirements. 23MnNiMoCr54 steel is a German grade, which was mainly imported from abroad until the 1980s and 1990s. Since the 1990s, domestic steel mills have been trialled in small quantities according to the requirements of German grade compositions. However, although the composition and the steel produced in Japan Similar, with domestic
