大连重型机器厂设计制造的热管和煤气加热炉是用于5吨炼钢电炉打结炉热衬用的耐火材料如镁砂、焦油等的加热工序上.炉体打对前需将镁砂均匀地加热到北106℃以上,焦油加热到80℃以上.再掺入镁粉,三者混拌均匀,即可投入炉体进行打结工序.热管材料采用20#无缝钢管,内壁镀 Dalian Heavy Machinery Plant design and manufacture of heat pipe and gas furnace is used for 5 tons of steel furnace knot furnace refractory lining with refractory materials such as magnesia, tar and other heating processes. Heated to above 106 ℃ in the north, the tar heated to above 80 ℃ .And then mixed with magnesium powder, the three mixed evenly, you can put into the furnace to knot the process.Heat-pipe material using 20 # seamless steel tube, the inner wall plating
