Corundum wearing-resistant plastic refractory and preparation method thereof
The invention provides a corundum wearing-resistant plastic refractory. The corundum wearing-resistant plastic refractory comprises corundum, chromium corundum, zirconite, alumina micro powder, zirconium powder, lanthanum and lanthanum group metal oxide micro powder, and 0.01-0.1% of yttrium powder. The invention further claims a preparation method of the corundum wearing-resistant plastic refractory at the same time. The preparation method comprises the steps of fine milling, pre-mixing, mixing, drying, sorting, checking, packaging and storing. Through adding zirconium powder, lanthanum and lanthanum group metal oxide micro powder, and yttrium powder, the high-temperature bonding property of the plastic is improved, and therefore the slag resistance, the thermal stability and the service life of the product are improved.
