What is the biggest difference between the billet mold copper tube and the round billet mold copper tube?
As we all know, the strength of the billet mold copper tube and the round billet mold copper tube of the same specification is determined by the shape. The strength of the billet mold copper tube is greater than the round billet mold copper tube, so the thermal deformation resistance is different. Conventional design standards, the wall thickness of the copper tube billet is 8%~10% of the nominal size of the billet; for example, the wall thickness of the 150-square mold copper tube is 12~15mm, and the round billet mold copper tube is also 8%~ 10%, because the round billet mold copper tube is easy to deform. For this reason, when Shandong Jinan Dongfang Mould Co., Ltd. designed the round billet mold copper tube, the wall thickness was 9%~12% of the nominal size of the billet, which improved the crystallization The strength of the copper tube.
