8K型电力机车是我国从西欧五十赫兹集团引进的货运机车,在两台车的合作生产中,8K车用钢板(法国供应)根据法方规定,在下料前要进行予处理。钢板进行予处理的主要作用为:1.钢板表面除油除锈。2.表面达到一定粗糙度,增强油漆的粘着力。予处理的钢板上喷可焊性底漆。我厂在无钢板予处理设备的情况下,委托武昌造船厂在从西德因特曼公司引进的钢板予处理流水线上进行钢板予处理。板厚大于6mm的在予处理线上进行喷丸,板厚小于4mm的采用人工用砂轮片磨削后再上予处
8K electric locomotive is a freight locomotive introduced from the fifty Hertz Group in Western Europe. In the co-production of two vehicles, the 8K car steel plate (supplied by France) is to be disposed of before cutting according to the law. Steel for pretreatment of the main role: 1. Steel surface degreasing rust. 2. The surface reaches a certain degree of roughness, enhance paint adhesion. Pretreatment of steel spray primer on the weldability. I plant in the absence of steel to the case of processing equipment, commissioned the Wuchang shipyard in West Germany from the introduction of the company to deal with the steel plate to the processing line for processing. Shot thickness of more than 6mm in the pre-treatment line shot peening, plate thickness of less than 4mm grinding with artificial grinding wheel after the place
