目前全国各地正在大力解决土铁利用问题为机械工业更大跃进扫清道路。但由于多数厂缺乏化验设备,无法化验分析,影响这项工作的开展。重庆黑色冶金设计院试验工厂建成的钢铁土化验室,设备简单,费用很少,一般县社工厂都有条件设置,对解决合理利用土铁的技术关键有其现实意义,现予转载,供大家多考。—编者 At present, efforts are being made to solve the problem of the utilization of soil and iron in all parts of the country to clear the road for greater leap forward in the machinery industry. However, due to the lack of laboratory equipment in most plants, it is impossible to test the analysis and affect the implementation of this work. Iron and steel laboratory built in Chongqing Black Metallurgical Design Institute pilot plant, the equipment is simple, the cost is very small, the general county community factory conditions are set to solve the rational use of soil iron technology has its practical significance, is reproduced for everyone More test. -editor
