用斯大林尼特硬質合金堆焊于快速磨損零件的表面,在我厂已广泛应用于PC-2型密閉式混胶机的混和轉子上。轉子的材料原为45-55-16,在鋼材缺乏的条件下,我厂正考虑轉子材料由鑄鋼改为球墨鑄铁,因此能否在球墨鑄铁上堆焊斯大林尼特成为决定代用的首要問題。試驗所用的球墨铸铁試件尺寸为120×60×40毫米,沿其表面堆焊斯大林尼特合金数層。焊条为我厂自制,直徑φ6毫米焊条芯采用CBO8。塗料成分;銘铁45％;
With Stalinit carbide hardfacing on the surface of rapidly wearing parts, it has been widely used in the mixing rotor of PC-2 closed mixing machine in our factory. Rotor’s material was originally 45-55-16, in the absence of steel conditions, our plant is considering the rotor material from cast steel to ductile iron, so it can be cast on ductile iron Stalinit became the decider to replace main issue. The ductile iron used in the test was 120 × 60 × 40 mm and a few layers of Stalinit alloy were deposited along its surface. Electrode for my factory-made, diameter φ6 mm electrode core using CBO8.
