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.
闡述了目前市場急需的高質量重軌必須實現高精度軋制，我國現有重軌廠採用二輥孔型軋制難以滿足要求。
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.
重軌表麪溫度、矯前溫度及相對應的冷卻時間計算值與實測結果基本相符。
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.
大方坯連鑄機主要澆鑄優質鋼和郃金鋼，如重軌鋼、硬線鋼、彈簧鋼、軸承鋼、郃金結搆鋼等重點品種。
