我厂焊补铸件使用的三种焊条,都能保证焊补质量,不影响机械加工。这几种焊条成本低,所用原料市场上都能够买到。现在介绍出来给大家参考。 1.软钢焊条:焊条芯是用退火过的直径4公厘的铁丝(退火温度800～850‘C℃)。药皮成分为生石灰(用熟石灰代替也可以)10％、小苏打13％、硼砂24％、二氧化锰20％、石英砂8％、石墨粉20％、黄血盐5％。各种药品都要用碾子研成细末,用120号筛子过筛。然后
I plant welding castings used in three kinds of electrodes, welding quality can be guaranteed, does not affect the machining. These electrodes are low cost, the raw materials used on the market can buy. Now introduced for your reference. 1. Soft steel electrode: The core is annealed with a diameter of 4 mm wire (annealing temperature 800 ~ 850’C ℃). The ingredients of the medicinal skin are quicklime (can also be replaced by hydrated lime) 10%, baking soda 13%, borax 24%, manganese dioxide 20%, quartz sand 8%, graphite powder 20%, yellow blood salt 5%. A variety of drugs should be used to study into a fine grinding machine, with 120 sieve sieve. then
