河北省辛集市民用机械厂与河北机电学院合作,完成了“辊锻方口钢锨”的研制。辊锻方口钢锨是由整块钢坯直接锻制成形的变截面锻件,该产品广泛用于矿山开采,筑路,建筑等行业,主要供外贸出口。方口钢锨是用扁钢经辊锻、切边、卷库、成形等工序制成。由于锨头部宽度大,锨库较长,锨头 Xinji City, Hebei Province civilian Machinery Factory and Hebei Institute of Mechanical and Electrical cooperation, completed a “roll forging square steel 锨” development. The square steel for roll forging is a kind of variable section forging which is forged directly from a single billet. The product is widely used in mining, road building and construction industries, mainly for export. Square steel 锨 is flat with roll forging, trimming, roll library, forming and other processes made. As 锨 head width, 锨 library longer, 锨 head
