10吨钢锭模是我公司为生产50Kg/M轨设计的专用锭模,近两年来用该锭模生产的钢锭占总钢锭产量的30～40％,其中约15％用于50Kg/M轨的生产。合理地确定10吨钢锭本体重量对提高成材率、增加公司的经济效益有极为重要的意义。 今年,结合50Kg/M轨的生产,初轧厂和轨梁厂对重轨坯料,轨梁热锯切头、切尾及成品轨单重进行了调查,并通过调查结果,提出我们对10吨锭本体重量的修改和重轨初轧坯尺寸公差的改进意见。 一、10吨锭本体重量的原始设计及改变情况
The 10-ton ingot mold is a special ingot mold designed by our company for the production of 50Kg / M rail. In the past two years, the ingot produced with this ingot mold accounts for 30-40% of the total ingot output, of which about 15% is used for 50Kg / M rail produce. Reasonably determine the body weight of 10 tons of ingot to improve the yield, increase the economic efficiency of the company is extremely important. This year, in combination with the production of 50Kg / M rails, the preliminary mill and the track beam factory investigated the weight of heavy rail blanks, the hot-headed cutting of rail beams, the tail cuts and the finished rails. Based on the survey results, Modification of ingot body weight and improvement on initial dimension tolerance of heavy rail preform. A, 10 tons of ingot body weight of the original design and change situation
