连铸用铝锆炭复合塞棒的研制与使用

Development and application of compound tap stopper from alumina zircon graphite for c.c.

本文介绍了利用电熔刚玉、鳞片状石墨、电熔锆莫来石、少量添加剂与结合剂,分别造粒后于150Mpa压力下一次复合而成整体式塞棒。其使用效果接近自德国进口的同类产品的水平。

This article introduced the whole tap stopper made of particles from fused corundum, scaled graphite, fused zircon mullite and a little of additive and binder under 150 Mpa. The effect of utilizing the tap stopper is approaching to the level of the same kind one imported form Germany.
