heavy rail

基本解释

The high quality heavy rail must be produced by high precision rolling technology. The conventional technology of 2-H mill adopted in our country is difficult to produced it.
阐述了目前市场急需的高质量重轨必须实现高精度轧制，我国现有重轨厂采用二辊孔型轧制难以满足要求。
The theoretical prediction values of the surface temperature of heavy rail, the straightening temperature and corresponding cooling time are in reasonable agreement with experimental results.
重轨表面温度、矫前温度及相对应的冷却时间计算值与实测结果基本相符。
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。
