铸管厂广大革命职工遵照毛主席关于“破除迷信,解放思想”的教导,打破洋框框,敢想敢干试制成功 HT 30—54低炭高强度(?)325×42×5000毫米连轧机输送辊。这项铸铁辊道新产品具有一定硬度,但又不致划伤钢板表面的良好性能。低碳铁水是由冲天炉强化冶炼而得,应用水平式离心铸造机生产。这项产品的试制成功为我国生产轧钢机铸铁辊道创出了一条既经济,又快的道路,为发展钢铁工业
The vast majority of revolutionary workers in the foundry plant, following Chairman Mao’s teachings on “breaking superstition and emancipating the mind”, set themselves apart from trying to make a successful trial of the HT 30-54 high-strength (?) 325 × 42 × 5000 mm continuous mill Roller. The cast iron roller new product has a certain hardness, but not scratch the surface of the steel plate good performance. Low-carbon hot metal is derived from the cupola enhanced smelting, the application of horizontal centrifugal casting machine production. The successful trial production of this product has created an economical and fast road for the production of rolling mill iron casting roller in China. In order to develop the steel industry
