大连工矿车辆厂铸钢车间积极采用以石代钢,成功地把辉绿岩铸石作耐磨件应用于混砂机上,为国家节约大量钢材。他们在S116型混砂机上采用辉绿岩铸石作耐磨件分别代替原来的锰钢辗底和普通钢围板,具有经久耐用,不粘砂、成本低,节省检修工时等优点。现五台混砂机已全部采用辉绿岩铸石作耐磨件,据估算,五年之内将可为国家节约钢材一百吨,资金五万六千元。 Dalian Industrial and mining vehicles plant steel shop to actively adopt the stone on behalf of the steel, the success of the diabase cast stone wear parts used in the sand mixer, save a lot of steel for the country. They use the S116-type sand mixer for the wear-resistant parts of diabase stone cast instead of the original manganese steel roller bottom and ordinary steel panels, with durable, non-stick sand, low cost, save maintenance hours and other advantages. Now five mixer has all used diabase stone for wear-resistant parts, it is estimated that within five years will be able to save the country a hundred tons of steel, capital 56,000 yuan.
