为了提高圆弹簧棒料加热质量,减轻劳动强度,遵照毛主席关于“我们必须打破常规,尽量采用先进技术”的教导,高举“鞍钢宪法”旗帜,组成三结合小组,通过向兄弟工厂学习,在一九七五年九月制成液压传动步进加热炉一台。经过投产试用证明:这种炉子加热的棒料氧化、脱碳少,质量均匀,改善了劳动条件,很受工人欢迎。 In order to improve the quality of round spring bar heating and reduce labor intensity, in accordance with Chairman Mao’s teachings on “We must break the routine and try our best to adopt advanced technology”, we should hold the banner of “Ansteel Constitution” and form a three-in-one team to learn from Brother Factory. In September 1975, it made a hydraulic transmission step heating furnace. Proved after commissioning trial: This furnace heated bar oxidation, decarburization less uniform quality, improved working conditions, very popular with workers.
