短應(yīng)力線軋機(jī)有什么特點(diǎn)？

短應(yīng)力線軋機(jī)具有體積小、重量輕、軋機(jī)剛度大、軸承使用壽命長(zhǎng)等優(yōu)點(diǎn)。近年來(lái)該軋機(jī)在小型軋機(jī)上使用越來(lái)越廣泛。隨著短應(yīng)力線軋機(jī)在線快速換輥裝置的出現(xiàn)，使軋機(jī)投資減少，導(dǎo)致其應(yīng)用將會(huì)更普遍。

What are the characteristics of a short stress line mill?  

Short stress line mill has the advantages of small volume, light weight, large rigidity of rolling mill and long service life of bearing. In recent years, the rolling mill has been used more and more widely in small rolling mill. With the emergence of on-line fast roll change device for short stress line rolling mill, the investment of rolling mill is reduced, and its application will be more common.

楔橫軋機(jī)類型有輥式、板式和單輥弧式楔橫軋機(jī)。三種類型的楔橫軋機(jī)相比，板式楔橫軋機(jī)模具制造較為簡(jiǎn)單，模具的調(diào)整比較容易，因而軋件的精度較高，并且工藝可靠.

The cross wedge rolling mill has roller type, plate type and single roll arc cross wedge rolling mill. Compared with the three types of cross wedge rolling mill, the mould manufacturing of the plate type cross wedge rolling mill is simpler and the adjustment of the die is easy, so the precision of the workpiece is high and the process is reliable.

四棍軋機(jī)的工作輥直徑較小，傳遞軋制力矩，軋延壓力由直徑較大的支承輥承受。這類設(shè)備的主要優(yōu)點(diǎn)是相對(duì)剛度較大，壓下量大、軋延力小，可軋制較薄的板材，也包括有可逆和連軋兩種。

The working roll diameter of the four bar mill is small, and the rolling torque is transferred. The rolling pressure is borne by the backup roller with larger diameter. The main advantages of this type of equipment are relatively large stiffness, large reduction, low rolling force, thin rolled sheets, and reversible and continuous rolling two.

使用熱軋的第二個(gè)優(yōu)點(diǎn)就在于其可以適當(dāng)?shù)母纳平饘僖约昂辖鸩牧系募庸すに囆阅?。也就是說(shuō)，其可以把較大的晶粒進(jìn)行破碎，同時(shí)可以減少裂紋的出現(xiàn)，這樣一來(lái)，也就相當(dāng)于減少了鑄造過(guò)程中的缺陷問(wèn)題，提高合金的加工性能。

The second advantage of hot rolling is that it can appropriately improve the processing performance of metal and alloy materials. That is to say, it can break the larger grain and reduce the appearance of the crack, which is equivalent to reducing the defects in the casting process and improving the processing performance of the alloy.
