What is the biggest difference between square billet copper mold tube and round billet copper mold tube?
As we all know, the strength of square billet copper mold tube is different from that of round billet copper mold tube with the same specification. The strength of square billet copper mold tube is greater than that of round billet mold copper tube, so the thermal deformation resistance is different.
According to the conventional design standard, the square billet of copper mould tube wall thickness is 8% ~ 10% of the nominal size of the billet; For example, the wall thickness of 150 square copper mould tube is 12 ~ 15mm, while the round copper mould tube is also 8% ~ 10%, because the round copper mould tube is easy to deform. Therefore, when designing the round copper mould tube, Shengmiao takes 9% ~ 12% of the nominal size of the billet, which improves the strength of the copper mould tube.
