Corten B hot rolled plate yield 3500 width steel plate production line

Our 12Cr2Mo1VR steel plate breaks through the specification limit, with a thickness of Corten B hot rolled plate yield up to 180 mm and a single weight of 43.7 tons. The flaw detection can meet the highest level of NB / T47013 flaw detection level. Its thickness and unit weight exceed the production limit of vanadium steel. The 12Cr2Mo1VR steel plate with such specifications has high technical requirements, severe performance requirements, and great production difficulties. In the Corten B hot rolled plate yield production process, it is easy to appear the tail area defects, which will cause the steel plate to fail inspection. So please choose your suppliers carefully.

After extrusion, the Corten B hot rolled plate yield tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

42CrMo alloy steel Corten B hot rolled plate yield: low temperature tempering welding performance thermal processing
The heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.
