heavy rail

基本解釋

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(zhì)量重軌必須實(shí)現(xiàn)高精度軋制，我國現(xiàn)有重軌廠采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.
重軌表面溫度、矯前溫度及相對應(yīng)的冷卻時(shí)間計(jì)算值與實(shí)測結(jié)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(jī)主要澆鑄優(yōu)質(zhì)鋼和合金鋼，如重軌鋼、硬線鋼、彈簧鋼、軸承鋼、合金結(jié)構(gòu)鋼等重點(diǎn)品種。

In heavy rail rolling by universal mill,a simplified 3-dimention geometrical model has been built firstly. The kinematically admissible velocity field of the web,head and base of rail have been determined respectively,moreover the corresponding shear strain rate have been also obtained.
在重軌萬能軋制過程中,首先建立了簡化的三維幾何模型,然后分別給出了軌腰、軌頭及軌底的運(yùn)動(dòng)學(xué)許可速度場以及相應(yīng)的應(yīng)變速度場和剪應(yīng)變速度強(qiáng)度。
