steel-backed bearing alloy

The relations between the tempering hardness and the temperature for hardened bearing steel and low alloy steel were studied.

研究了淬硬轴承钢及一些低合金钢回火硬度与回火温度的关系。

The fatigue life test of casting bearing steel showed that the steel treated with barium alloy and casted with lower superheat temperature, lower casting speed and soft cooling process can be used for producing quality bearing.

结果表明：采用钡合金处理钢液、低过热度、低拉速和弱冷却连铸工艺可使连铸轴承钢的疲劳寿命满足优质轴承的考核寿命要求。

Influence on stable load bearing of scaffold by using pellicle-low alloy steel pipe

薄壁低合金钢管杆件对脚手架稳定承载能力的影响

When studying the stable load bearing of scaffold made of pellicle-low alloy steel pipe, it was found if the actual load was lower than 73% designed load the steel pipe remains safe.

将薄壁低合金钢管用于脚手架时，对其稳定承载能力的研究表明：当荷载作用的设计值小于其稳定承载能力设计值的73%时，杆件安全；

A bloom continuous Casting machine main cast quality steel and alloy steel, such as heavy rail steel, hard-line steel, spring steel, bearing steel, alloy structural steel, and other key species.

大方坯连铸机主要浇铸优质钢和合金钢，如重轨钢、硬线钢、弹簧钢、轴承钢、合金结构钢等重点品种。
