Q345 hot-rolled seamless steel pipe knowledge shared by Shandong Liaocheng Q345B seamless steel pipe plant
The process flow of q345 hot-rolled seamless steel pipe is mainly perforated, rolled pipe and fixed reduction. Q345 is a steel material. It is a low alloy steel and will decrease its yield value as the thickness of the material increases. Q345A, Q345B, Q345C, Q345D, Q345E. This is a distinction of grades, which represents the difference in the temperature of the impact. Q345 hot-rolled seamless steel pipe in the rolling tube should pay attention to the problem First, the thick-walled capillary tube into a thin-walled waste pipe (wall extension) must first ensure that the waste pipe has a higher wall thickness uniformity; The tube has a good internal and external surface quality. The main purpose of the rolling tube is to determine the wall thickness of the step tube.
