继南京永利宁厂和哈尔滨锅炉厂之后,发展化学肥料生产的重要设备——高压容器于六月十一日又在大连工矿车辆厂试制成功。本厂是根据德国冶金专家孔歇尔教授建议,采用国产高强度低合金结构钢板St52和K2M钢德国钢种水代替进口锅炉钢板20K和24铜,它只含有少量合金元素,而强度即大大提高(见表1)。原来筒体为二十一层,现在减少到十四层,按下半年生产任务计算,可节约工时和钢材共八十万元。由于筒体层数的减少,筒体环缝深度从139公厘减到97公厘,两端环
Following the Nanjing Yongli Ning Factory and the Harbin Boiler Works, the development of an important equipment for the production of chemical fertilizers, the high-pressure vessel, was successfully piloted in Dalian Industrial and Mining Vehicle Factory on June 11. The factory is based on the German metallurgical experts Professor Klose recommended the use of domestic high-strength low-alloy steel plate St52 and K2M German steel instead of imported steel boiler plate 20K and 24 copper, which contains only a small amount of alloying elements, and the strength is greatly enhanced (See table 1). The original cylinder is twenty-one layers, and now reduced to fourteen layers, according to the second half of the production tasks can save hours and steel a total of eight hundred thousand yuan. Due to the reduction of the number of cylinder layers, the cylinder girdle depth was reduced from 139 to 97 mm and both ends of the ring
