自流成型蜂窝体的研制与应用

Development and application of the self-flow casting honeycomb regenerator

以电熔白刚玉、莫来石、氧化锆细粉、硅微粉、氧化铝微粉、纯铝酸钙水泥添加剂等为主要原料,研究了自流料的高温性能和热震稳定性。结果表明,所研究的自流料具有良好的高温性能和热震稳定性,自流成型的蜂窝体在蓄热式加热炉上使用,寿命已达一年,目前仍在使用。

An investigation on high temperature performance and thermal shock resistance of self-flow castables was conducted by adopting fuse white corundum, mullite, ZrO2 fine powders, silica and Al2O3 micro powders, pure calcium aluminate cement additive, etc. as main raw materials. The results showed that the self-flow castables studied are of favorable high temperature performance and thermal shock resistance, which can be well represented by the achievement that service life of self-flow casting honeycomb regenerator applied to regenerative heating furnace has been lasting for a year and still in service at present.
