Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the Q460D carbon steel plate sheet steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of Q460D carbon steel plate sheet seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life.
