矿热炉水冷保护屏的新设计

水冷保护屏的材质由锅炉钢、不锈钢、锻造铜板改为纯铜；工艺由锅炉钢、不锈钢板冷弯、焊接，锻造铜板的机械加工、焊接制造改为主体部分用电解铜材料上引铸造；悬挂和水口零件部分与主体焊接。利用纯铜材质的高效导热率、隔磁性、耐腐蚀性，有效地降低自身的温度，使用寿命大大提高。并且废旧的保护屏回收价值很高，可大大降低二次投资成本，值得推广。

AN INNOVATION DESIGN OF ORE HEATING FURNACE WATER-COOLING SHIELD

In the new design , the materials of water-cooling shield include boiler steel , stainless steel and pure copper that is changed from forged copper plate , its manufacturing process is cold bending and welding of boiler steel and stainless steel , and upward casting of pure copper for the main part of the shield which is changed from machining and welding of forged copper plate , the hung parts and water in-let （ or outlet ） parts are welded to the main part .Pure copper has good heat conductivity , magnetic isola-tion and corrosion resistance , can lower its temperature effectively , and greatly improve its service life . The shield has highly recovery value that can reduce reinvestment cost remarkably .As a result, the pro-motion of the new method has a bright future .
