新型Q890高强钢在液压支架中的应用研究
|
摘要
分析了液压支架用钢的发展趋势和性能要求,并针对某新型Q890高强钢进行了切割、成形及焊接工艺研究,给出了可用于指导生产的工艺参数。实践结果表明,液压支架选用新型Q890高强钢板制造,在同等工作阻力下,可节约钢材22.5%、焊材37.8%,并使液压支架具有更高的强度及塑韧性,提高了液压支架的抗压能力、使用寿命、使用安全,经济和社会效益显著。
The development trend and performance requirements of steel used for hydraulic support were analyzed,and study on thermal cutting, forming and welding technology of a new-type Q890 high-strength steel was conducted,and the process parameters used to guide production were given. The practice results show that the hydraulic support made with new-type Q890 high-strength steel,under the same working resistance,can save 22.5% of steel and 37.8% of welding materials,and endowed hydraulic support with higher strength and toughness of the reserves,raise the anti-pressure capacity,service life and the use safety of hydraulic support. Economic and social benefit is remarkable.
