短應(yīng)力線軋機(jī)具有如下優(yōu)點(diǎn)：

⑴容易實(shí)現(xiàn)負(fù)公差軋制，因?yàn)檐垯C(jī)的高剛度保證了產(chǎn)品的。

⑵可實(shí)現(xiàn)軋機(jī)左右兩個(gè)軸承的對稱調(diào)整，這對于穩(wěn)定軋制條件，提高作業(yè)率，節(jié)省檢修和更換導(dǎo)衛(wèi)、橫梁時(shí)間等具有重要意義。

Short stress line mill has the following advantages:

It is easy to realize negative tolerance rolling mill, because of the high rigidity to ensure high precision products.  

The symmetric adjustment can achieve about two rolling bearings, the stable rolling condition, improve operation efficiency, saving maintenance and replacement has important significance to guide and beam time etc.

在鍛造和軋制生產(chǎn)中，鋼坯一般在完全燃燒火焰的氧化氣氛中加熱。采用不完全燃燒的還原性火焰（即“自身保護(hù)氣氛”）來直接加熱金屬，可以達(dá)到無氧化或少氧化的目的。這種加熱方式稱為明火式或敞焰式無氧化加熱，成功地應(yīng)用于轉(zhuǎn)底式加熱爐和室式加熱爐。

In forging and rolling production, billets are usually heated in the combustion atmosphere of complete combustion flame. The direct combustion of metal can be achieved by the incomplete combustion of reduced flame (i.e., the "self protective atmosphere"), which can achieve the  of no oxidation or less oxidation. This heating method is called open flame or open flame oxidation free heating, which has been successfully applied to rotary hearth furnace and chamber heating furnace.
