棒材精軋件后為什么要采用穿水冷卻工藝？軋件軸線與軋輥軸線平行，軋件作轉(zhuǎn)動，其轉(zhuǎn)動方向與軋輥相反，進(jìn)出料需專門裝置。（1）提高了產(chǎn)品的力學(xué)性能；（2）減少了產(chǎn)品表面二次氧化損失；（3）穿水后，由于軋件溫度低，剛度大，在冷床輸入輥道上事故減少，軋件在冷床上冷卻時塌腰彎曲減少，可以提高成材率和產(chǎn)品質(zhì)量；（4）冷床長度可相應(yīng)減少。

Why do we need to wear water cooling technology after finishing bar?

(1) improve the mechanical properties of the product; (2) reduce the two oxidation loss on the surface of the product; (3) after water, because the rolling temperature is low, the stiffness is large, the accident on the roller table of the cold bed is reduced, the bending of the rolled piece in the cold bed is reduced, the yield and quality of the product can be improved; (4) the length of the cold bed can be reduced correspondingly.

我國經(jīng)濟(jì)一直快速穩(wěn)定發(fā)展，而軋鋼設(shè)備行業(yè)也是迅速發(fā)展，在我國軋鋼機(jī)設(shè)備行業(yè)中，自動化和計算機(jī)控制系統(tǒng)主要還是靠引進(jìn)。

China's economy has been developing rapidly and steadily, and the steel rolling equipment industry is developing rapidly. In China's steel rolling machine equipment industry, automation and computer systems are mainly
