Composite fire-resistant prefabricated brick for artificially synthesized mica smelting furnace and preparation method of composite fire-resistant prefabricated brick
The invention provides a high-temperature-resistant and corrosion-resistant fire-resistant precast block, the fire-resistant precast block comprises a working surface and a backing surface, and the working surface realizes corrosion resistance by using small-size crystal grains and a unique dendritic eutectic structure formed by white corundum, zirconium oxide or synthetic fused alumina zirconia under a high-temperature condition; the bridging agent A is added into the working face raw material, the bridging agent B is added into the backing face raw material, and the working face and the backing face form a complete integrated structure under the action of the bridging agent A and the bridging agent B, so that the working face is prevented from falling off, pollution to products is avoided, impurities in artificially synthesized mica are further reduced, and the service life of the mica is prolonged. And the product yield is improved.
本发明提出一种耐高温、耐侵蚀的耐火预制块，该耐火预制块包括工作面和背衬面，工作面利用白刚玉、氧化锆或合成锆刚玉在高温条件下形成的小尺寸晶粒和独特的枝状共晶结构，实现抗侵蚀性能；在工作面原料中加入桥接剂A，在背衬面原料中加入桥接剂B，通过桥接剂A和桥接剂B的作用使得工作面和背衬面形成完整的一体结构，从而避免了工作面的脱落，进而避免了对产品的污染，进一步减少了人工合成云母中的杂质，提高了产品的收率。
