阐述了目前液压支架用立柱中缸管工艺的缺陷,改变传统的工艺,大胆采用新工艺,调整工艺顺序,针对不同的材质采用不同的工艺,减少了中缸管堆焊层处气孔的产生,并提高了堆焊层的硬度,此工艺提高了生产效率,目前在国内外处于领先水平,并被广泛推广。
The defects of the cylinder tube in the column for hydraulic support are expounded. The traditional process is changed, the new process is adopted boldly, the process sequence is adjusted, the different process is adopted for different materials, the generation of blowholes in the middle tube stack is reduced, And improve the hardness of surfacing layer, this process improves production efficiency, at home and abroad at the leading level, and has been widely promoted.
