农用复合周期断面钢材,是综合双金属轧制和周期断面钢材轧制的加工方法而设计出来的新品种。由于它是以各种铁制小农具使用性能和目前手工业生产特点为依据,并尽可能提高手工制造农具的劳动生产率、提高质量和降低农具成本而设计的,因此它是作为小农具制造原料的一种经济断面钢材。这种钢材于1963年试轧成功,今年即将投入生产,本文主要将这种钢材的有关生产技术问题作一初步介绍。一、目前小农具的生产简况根据全国手工业管理总局提供的资料,1963年全国手工业系统共用钢材33.6万吨(其中13.6万吨为边角废料),仅锄头、镰刀、镐、锹等四个主要品种农具就生产了约两
Agricultural composite periodic cross-section steel, is a new variety of dual-metal rolling and periodic cross-section steel rolling processing method designed. Because it is designed on the basis of the performance of various iron small tools and the characteristics of current handicraft production and maximizing the labor productivity of handmade tools, improving the quality and reducing the cost of tools, it is used as a raw material for small tools An economic section of steel. This kind of steel was successfully trial-rolled in 1963 and will be put into production this year. This article mainly introduces the production technology of this kind of steel for a preliminary introduction. First, the current production of small tools According to the information provided by the China Administration of Art, the handicrafts system in the country in 1963 336,000 tons of steel (of which 136,000 tons for scrap scrap), hoes, sickles, picks, spade and other four major Varieties of agricultural tools on the production of about two
