从1970年起,工厂中就掌握了电磁结晶器铸锭铸造的工业工艺技术。起初,这一先进的铸造方法用于生产圆铸锭。以后,工作的主要方向就改为扁铸锭铸造工艺的研究,因为扁铸锭必须铣去6～7毫米的表面层。铸造成功表面光滑的铸锭,就可以省略铣面作业,而获得很好的经济效果。生产时在电磁结晶器中铸造扁铸锭的方法可以分为以下三个阶段: 研究适宜的结晶器结构和掌握断面为300×1460毫米、长到6米铝-镁系合金扁铸锭的铸
Since 1970, the factory has mastered the industrial process technology for the casting of electromagnetic mold ingots. Initially, this advanced casting method was used to produce round ingots. Later, the main direction of work was changed to the research of the casting process of the flat cast ingot, because the flat cast ingot must be milled to the surface layer of 6 to 7 mm. Casting a smooth surface of the ingot, you can omit the milling operation, and get good economic results. The method of casting the flat ingot in the electromagnetic mold during production can be divided into the following three stages: researching the proper mold structure and mastering the casting of the aluminum-magnesium alloy flat ingot with a cross section of 300 × 1460 mm up to 6 m
