火炮身管用钢各国有其特点,我国有许多钢号是很有特色的,然而往往不易纳标,而引进的东西却容易被人接受。随着产品更新,对火炮身管用钢的性能提出了更高的要求,单纯用调整化学成分是很难达到的,必须对钢的精炼工艺予以创新。最佳的过程冶金工艺组合应从产品的性能要求出发,以获得最佳的经济效益为目的。火炮身管的设计应从单纯追求强度转变到“适当的强度,高的塑、韧性”的轨道上来。在强度计算中采用σ_(0.1),比采用σ_p较为合适。 Gun barrel steel has its own characteristics, many of our steel is very unique, but often not easy to accept the standard, but the introduction of things is easy to be accepted. As the product is updated, the performance of the gun barrel steel made higher requirements, simply to adjust the chemical composition is difficult to achieve, the steel refining process must be innovative. The best combination of process metallurgical process should be based on the performance requirements of the product, in order to obtain the best economic efficiency for the purpose. Artillery barrel design should change from the simple pursuit of strength to “appropriate strength, high plasticity, toughness” track. In the strength calculation using σ_ (0.1), than using σ_p is more appropriate.
