Two kinds of forming process knowledge of Q345B square steel pipe

1: Extrusion processing: using Q345B square pipe production line equipment, the machine is composed of four extrusion forming wheels at the front, rear, left and right.Katra grupa duas rotationes habet, et duae grupae semper in series ordinentur.Cubiculae sine sinus secundum rotationem rotantur.The shaft is guided into the first group of extrusion forming wheels→secundum grupam rotarum extrustionis formantur→the third group of extrusion forming wheels (the number of extrusion forming wheels depends on the actual specifications and models), Q345D seamless steel pipe Seam steel pipes are gradually extruded. The production characteristics of Q345B seamless square pipe manufacturers are highly efficient, faster and low in consumption.In addition to larger diameters, this type of processing technology is generally used.

2: Cold-drawn forming: the diameter of the top of the seamless tube blank is reduced, Q345B square tube-Q345B seamless square tube-Q345B square steel tube-Q345B cold drawn square tube-Shandong Dingyu Metal Material Co.Ltd. then crosses the Q345B square steel tube to form The abrasive tool is connected with the driving force of the generator set.Under the effect of the driving force, the seamless tube is blank produced and processed in Q345B square steel pipe according to the shaped abrasive tool.Hoc modus production is et processionis conformitur ad parabolam specificationis Q345B quadraticum pellicum quadraticum.An abrasive tool, the Q345D seamless steel pipe abrasive tool cannot adjust.The relative cost of one ton of abrasive tools is high, and the finished product is highly accurate in single production and processing. It can also be equipped with an internal grinding tool in the tube in general production and processing.Q345B seamless square tube manufacturer's production characteristics knowledge enables the internal and external abrasive tools to cooperate with each other to produce and process
