“钢管技术”1984年第5期,邢瑞祯同志的“冷拔钢管减径量与减壁量之间的关系”一文提出,采用短芯棒拔制钢管时,编制拔制表不仅要考虑延伸系数,同时也要考虑减径量与减壁量之间的关系。邢文从定性意义认为“实际上减径量与减壁量之间的关系正确与否,对钢管拔制力的大 “Pipe technology” 1984 the fifth period, Comrade Xing Rui-zhen, “the relationship between the reduction of the amount of cold drawn steel pipe and the amount of reduction of the wall,” a paper proposed, drawn short steel pipe, the preparation of the draw table not only to consider the extension coefficient , But also consider the relationship between the amount of reduction and the amount of reduction. Xing Wen from the qualitative significance of that "in fact the amount of reduction and reduction of the amount of the relationship between the right or not, on the steel drawing power
