我厂为了保证今年大量生产新货车任务的需要,自制成一套生产电焊条的简易设备,并投入了小批试生产。经过检验和使用,证明电焊条质量良好。生产的焊条类型是灰黑色42型电焊条,主要用来焊接低碳钢结构。所用焊芯钢丝成分要求:C<0.10％;Si<0.03％;Mn0.35—0.6％;S<0.03;P<0.03％。药皮配方为:钛白粉6％;金红石28％;长石10％;常锡白泥20％;木层5％;锰矿8％;云母8％;高碳锰铁12％;铁砂10％。目前由于原料供应困难,因此常鍚白泥以陶土5％加黄土15％代用,高碳锰鉄以铸造用锰铁
I plant in order to ensure mass production of new trucks this year, the task needs to self-made a set of simple equipment for the production of welding electrodes, and put into trial production. After testing and use, that the quality of welding electrodes. The type of electrode produced is a gray-black Type 42 electrode, which is mainly used to weld mild steel structures. The core wire composition used requires: C <0.10%; Si <0.03%; Mn 0.35-0.6%; S <0.03; P <0.03%. The prescription of the medicinal skin is as follows: 6% of titanium dioxide, 28% of rutile, 10% of feldspar, 20% of limestone of Changxiu, 5% of wood layer, 8% of manganese ore, 8% of mica, 12% of high carbon ferromanganese and 10% of iron sand. At present, due to the difficulty of raw material supply, so often 钖 clay to clay 5% plus loess 15% substitution, high-carbon manganese 鉄 to cast with ferromanganese
