首先确定所需压力的大小,主要取决于以下几方面:被矫钢材的品种、规格;待矫轧件的原始弯曲程度;待矫轧件的终轧温度;被矫轧件的机械性能;矫直温度等。
First, determine the size of the required pressure, which mainly depends on the following aspects: the varieties and specifications of the straightened steel, the original bending degree of the rolled piece, the finishing temperature of the rolled piece, the mechanical properties of the leveled piece, the straightening temperature and so on.
冷床下料装置将其收集成组送至输出辊道上,冷床厂家, 再由输出辊道将其送到冷剪剪切成定尺成品。冷床的设计质量与安装精度直接决定着产品的Zui终质量。
The cooling bed feeding device collect group sent to the output roller, the roller output will be sent to the cold shear into thespecified product. Design quality and installation accuracy of cooling bed directly determines the final quality of the product.
当流态层温度为250℃时,奥氏体分解温度为550~600℃,冷床,同铅浴淬火相似;当流态层温度为300℃时,冷床报价,奥氏体分解温度约为500℃左右,冷床价格,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.
