Abstract
The present invention provides a production method of zirconia-corundum refractory bricks. In the method, high-temperature oxidation aluminium powder, zircon sand, desilication zirconium, sodium carbonate, borax and waste materials (secondary casting materials) are used as raw materials for preparing zirconia-corundum refractory bricks. The zirconia-corundum refractory bricks having low cost and good quality are produced by the control of each component content and the methods of batching fusion, etc.
Description
Technical field
The present patent application relates to a kind of refractory materials---the manufacture method of zirconia-corundum refractory brick.
Background technology
At present, the glass kiln adopts full raw material method to produce with refractory brick is a kind of by traditional technology, and the full waste material method of another kind of employing is produced, and CN1019666B is disclosed as Chinese invention patent, and the former can be protected at quality product, but production cost is too high; Though latter's production cost is low, quality product can not effectively be ensured, mainly is that wherein silicon-dioxide and foreign matter content is difficult to control.Also there is employing that the method that raw material and waste material combine is produced in addition, CN1322696A is disclosed as Chinese patent application, but this patent application does not specifically disclose each components contents in the used raw material on the one hand, used waste material is only disclosed---the content of each active principle in the secondary cast material, also there is certain drawback in its production method on the other hand, promptly when fused raw material, do not adopt fused mode in batches, thereby be difficult to make its fusion homogenizing, thereby influenced the final quality that obtains product.
