Preparation method of composite sand mould plate for producing fused zirconia corundum product
The invention provides a preparation method of a composite sand mould plate for producing a fused zirconia corundum product. The preparation method comprises the following steps: step 1, manufacturing a corundum sand mould: mixing a white corundum sand material and a binding agent, molding, baking at high temperature, and storing for later use after molding; step 2, manufacturing a composite sand mold plate: putting a layer of mixture into a mold, then putting the corundum sand mold obtained in the step 1 into the mold, then filling the mixture into a gap between the corundum sand mold and the mold again, and then carrying out vibration molding to remove attached sand; step 3, standing at room temperature for self-hardening to form a composite sand mould plate, and then taking out the composite sand mould plate from the mold; and step 4, carrying out coating spraying operation on the composite sand mold plate, and then standing for 72 hours at room temperature. The preparation method provided by the invention is simple and convenient to operate, and the composite template is relatively high in structural strength and relatively few in pores, so that the quality of a cast refractory material can be effectively improved.
本发明提供一种生产电熔锆刚玉产品的复合砂型板的制备方法，它包括以下步骤：步骤一、刚玉砂型的制作：将白刚玉砂料和结合剂混合后，打制成型而后进行高温烘烤，待成型后存放备用；步骤二、复合砂型板的制作：在模具中放入一层混合料，而后将步骤一种所得的刚玉砂型放入到模具中，而后向刚玉砂型与模具的缝隙之间再次填充有混合料，而后振动成型除去附砂；步骤三、室温静置自硬后形成复合砂型板，而后将其从模具中取出；步骤四、对复合砂型板进行涂料喷涂作业，而后室温静置72小时即成。本发明提供的制备方法简单，便于操作，这种复合型的型板结构强度较强气孔较少能有效的提升熔铸耐火材料品质。
