为了掌握鑄铁冷焊的方法,曾参考了各种資料,吸收了兄弟厂的經驗并作了长时間的試驗,其中以使用在焊道上洒焊剂用包药皮的焊条冷焊的方法性能最为优越,适用的范圍也較广泛,同时,成本还比較低廉。焊剂的配方和制造 1.硼砂50％、氫氧化鉀17％、氧化鉄皮(鍛件脫落下来的氧化皮)31％、白堊粉(碳酸鈣)2％。 2.熔炼:用一个鑄鉄坩堝或是鉄箱,把氫氧化鉀鋪在最下层,然后将氧
In order to grasp the method of cold welding of cast iron, various information has been consulted, which has absorbed the experience of Brother Plant and has been tested for a long time. The method of cold welding using welding rod coated with flux on the weld bead The most superior, the scope of application is also more extensive, at the same time, the cost is still relatively low. Flux formulation and manufacturing 1. Borax 50%, potassium hydroxide 17%, 氧 oxide skin (forging falling off the scale) 31%, chalk powder (calcium carbonate) 2%. 2. Smelting: Use a cast crucible or trowel box, the shop in the lowest potassium hydroxide, and then oxygen
