Two kinds of forming process knowledge of Q345B square steel pipe

Article author:administrators release time:2021-08-10 14:25:41 Reading:205

1: Extrusion processing: using Q345B square steel pipe production line equipment, the machine equipment is composed of four extrusion forming wheels at the front, rear, left, and right. Each group has two rotating shafts, and the two groups are continuously arranged in series. The seamless tube blanks are rotated according to the rotation. The shaft is guided into the first group of extrusion forming wheels→the second group of extrusion forming wheels→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 blank is produced and processed into Q345B square steel pipe according to the shaped abrasive tool. This kind of production and processing method is matched with a specification model Q345B square steel pipe. An abrasive tool, the Q345D seamless steel pipe abrasive tool cannot be adjusted. 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 high-precision Q345B square steel pipes. After forming, they undergo quenching and other heat treatment processes to remove the thermal stress of the pipe fittings. Q345D seamless steel pipes have high production and processing methods. The efficiency is relatively low, and the consumption of goods is very large. Generally, only Q345B square steel pipes of relatively caliber are produced, and high-precision Q345B square steel pipes are manufactured.
