非对称截面铸铁梁在煤矿中应用广泛,因为铸铁的价格便宜,更主要的是铸铁的抗压性能远大于抗拉性能,如使用合理,既经济又能充分发挥材料的抗压优势,但由于它不是对称截面的铸铁梁,在煤矿实际应用中需注意梁的使用方法。
Asymmetric cross-section cast iron beam is widely used in coal mines, because the price of cast iron is cheap, more importantly, the compressive strength of cast iron is far greater than the tensile properties, such as the use of reasonable, both economical and give full play to the material compression advantages, It is not a symmetrical cross-section of cast iron beams, the practical application of the mine should pay attention to the use of beams.
