Preparation method of ceramic core material for refining alloy casting grains and slurry stirring equipment
The invention relates to the field of aerospace material manufacturing, in particular to a preparation method of a ceramic core material for refining alloy casting grains and slurry stirring equipment. The invention provides a preparation method of a ceramic core material for refining alloy casting grains, which comprises the following steps: weighing 87-91 parts by weight of silicon dioxide, 3-5 parts by weight of hafnium tetrachloride, 2-5 parts by weight of aluminum oxide and 1-9 parts by weight of catalyst, and fully mixing by using a stirrer. The catalyst is added into the raw materials of the ceramic core material for preparing the alloy casting grains, so that the prepared ceramic core material has a fine grain effect, a surface layer containing the catalyst does not need to be additionally coated, and the problem that the surface layer falls off in the subsequent process is avoided.
本发明涉及航天材料制造领域，具体涉及细化合金铸件晶粒的陶芯材料制备方法、浆料搅拌设备。本发明提供了一种细化合金铸件晶粒的陶芯材料制备方法，按照重量份计，称取二氧化硅87—91份，四氯化铪3—5份，氧化铝2—5份，催化剂1—9份，使用搅拌机充分混合。通过在制备合金铸件晶粒的陶芯材料的原料中加入催化剂，使得制备后的陶芯材料本身就具备细晶的效果，而无需额外涂覆含有催化剂的面层，进而避免在后续工艺中面层脱落的问题。
