我院胡梦怡副教授等与贵阳钢厂合作研究高精度优质钎钢的生产工艺。研究了55SiMnMo钢坯的合理退火工艺,改制了喷吸钻具和研制了喷吸钻头。提高了钻头寿命和钻孔速度。确定了最佳轧后控制冷却工艺参数。研制了适合于制造重型钎杆的40SiMnMo
Associate Professor Hu Mengyi hospital and other Guiyang steel mills to study the production of high-precision high-quality stainless steel. The reasonable annealing process of 55SiMnMo steel billet was studied, the spray suction drill was modified and the nozzle was developed. Improved bit life and drilling speed. After determining the best rolling control of cooling process parameters. Developed 40SiMnMo for heavy duty drill rods
