CN101966641A 一种制造铝板生产用卷筒的方法及其用该方法制造的卷筒 无效 - 驳回

一种制造铝板生产用卷筒的方法及其用该方法制造的卷筒
摘要：
本发明公开一种制造铝板生产用卷筒的方法，其工艺步骤为：①配料，②熔炼，③浇注，即将熔融的钢液浇注到离心铸管管模中，④脱模，⑤正火，⑥回火，⑦粗加工，⑧调质，⑨精加工。使用该生产技术生产的卷筒，常温下屈服强度≥827MPa，400℃条件下屈服强度≥792MPa，600℃条件下屈服强度≥634MPa，有效保护铝板带轧制、堆放、吊运和退火时卷材的内外质量，使用时间长，性能可靠。
摘要（英）：

The invention discloses a method for manufacturing a winding drum for aluminium sheet production, which comprises the following process steps of: 1, mixing materials; 2, smelting; 3, casting, namely casting molten steel into a pipe die of a spun cast pipe; 4, demolding; 5, normalizing; 6, tempering; 7, roughing; 8, hardening and tempering; and 9, finishing. The winding drum produced by the production technology has the yield strength of more than or equal to 827MPa at normal temperature, the yield strength of more than or equal to 792MPa at 400 DEG C and the yield strength of more than or equal to 634MPa at 600 DEG C, effectively protects the internal and external quality of coils when aluminium sheet strips are rolled, stacked, hoisted and annealed, and has the advantages of long service life and reliable performance.
