耐磨板NM450行情(图1)

  NM450耐磨板轧后冷却可分为轧后工艺冷却和轧后自然冷却两种。轧后工艺冷却是指对不同钢号的NM450耐磨板根据不同的化学成分、厚度、轧制工艺和性能要求采用不同的冷却方式、冷却…

The cooling of nm450 wear-resistant plate after rolling can be divided into process cooling and natural cooling. Process cooling after rolling refers to adopting different cooling methods and cooling methods for nm450 wear-resistant plates of different steel grades according to different chemical composition, thickness, rolling process and performance requirements
NM450耐磨板轧后冷却可分为轧后工艺冷却和轧后自然冷却两种。轧后工艺冷却是指对不同钢号的NM450耐磨板根据不同的化学成分、厚度、轧制工艺和性能要求采用不同的冷却方式、冷却速度、开冷和终冷温度,以控制组织结构和综合力学性能。
The cooling of nm450 wear-resistant plate after rolling can be divided into process cooling and natural cooling. Process cooling after rolling refers to different cooling methods, cooling rates, starting and final cooling temperatures for different grades of nm450 wear-resistant plates according to different chemical composition, thickness, rolling process and performance requirements, so as to control the microstructure and comprehensive mechanical properties.
为了实现控制冷却热轧后NM450耐磨板要在矫前或热矫后进行强制冷却,主要采用水幕冷却、管层流冷却和汽水混合喷射冷却。在冷床上冷却的温度在200?150以下,对冷床的要求是使NM450耐磨板冷却均匀,并防止NM450耐磨板表面的刮伤
In order to achieve controlled cooling, the nm450 wear-resistant plate after hot rolling should be forced cooled before or after straightening, mainly using water curtain cooling, pipe laminar cooling and steam water mixed jet cooling. The cooling temperature on the cooling bed is below 200? 150. The requirement of the cooling bed is to make the nm450 wear-resistant plate cool evenly and prevent the scratch on the surface of the nm450 wear-resistant plate
