反压铸造,由于它的充型、结晶和凝固过程始终是处于高的压力场作用下,以及充型压力、充型速度和熔池中的气氛种类和分压可控性等一系列优点,正日益为广大铸造工作者所重视。 我所从81年起开展了对反压铸造设备的研制及其在铝合金砂型铸造上的应用,并于82年10月通过了对设备的技术鉴定。 Backpressure casting, because of its filling, crystallization and solidification process is always under the action of the pressure field, as well as filling pressure, filling speed and melting pool atmosphere type and partial pressure controllability and a series of advantages, Is increasingly valued by the majority of foundry workers. From 81 onwards, I started the development of the anti-pressure casting equipment and its application in the aluminum alloy sand casting, and in October 82 passed the technical appraisal of the equipment.
