冷床厂家服务放心可靠「多图」

拉钢式冷床，其特点是利用单爪绳式或链式拉钢机，横向成批拖运轧件。这种拉钢机往往配备有潜行装置，以达到有选择性地拖运某一根（束）轧件的目的。潜行装置有两种形式：一种是杠杆式，另一种是滑块式。

Pulling type cooling bed is characterized by single rope or chain machine, horizontal rolling batch haulage. This kind of steel are often equipped with stealth device to selectively hauling a workpiece to root (beam). There are two forms of the lurking device: one is leveraged, the other is a slider.

近年来, 为适应轧制制度变化繁多, 产品规格多、优质产品及高产量等要求, 我院认真消化、吸收国内外***技术, 设计了一套具有同类***水平的高速度、多品种、高质量的小型型钢和棒材冷床设备, 年产棒材可达90万吨, 已达到了国外同类设备的***水平。

In recent years, in order to adapt to various changes in rolling system, many specificati***, high quality products and high output, our hospital has carefully digested and absorbed advanced technology at home and abroad, designed a set of ***all steel and bar cold bed equipment with high speed, variety and high quality with the same kind of International advanced level. The annual production of rod can reach 900 thousand t***, which has reached the advanced level of the same kind of equipment abroad.

当流态层温度为250℃时，奥氏体分解温度为550～600℃，同铅浴淬火相似；当流态层温度为300℃时，奥氏体分解温度约为500℃左右，比铅浴淬火还低。

When the temperature of the flow layer is 250 C, the austenite decomition temperature is 550~600, similar to that of lead bath quenching. When the flow state temperature is 300, the austenite temperature is about 500 C, which is lower than the lead bath quenching.
