Manufacturing method for ceramic mold casting
The invention discloses a manufacturing method of ceramic mold casting, which comprises the following steps of refractory material selecting, adhesive selecting, electrolyzed water preparing, ceramicslurry preparing, ceramic slurry pouring, drawing, torch firing, and roasting, wherein a ventilating agent and a coagulation accelerator are added during preparation of the ceramic slurry, the gelatinization time after ceramic slurry pouring can be adjusted through the addition amount of a coagulation accelerator, the gelatinization time for a small piece can be controlled to be 4-6 seconds, the gelatinization time for medium and large pieces can be controlled to be 8-15 seconds, when the drawing time is about two times of the gelatinization time, the roasting temperature is 870-950 DEG C after gelatinizing is conducted for 5-15 minutes, roasting lasts for 1-3 hours, and therefore cracks are prevented from being generated. Products machined through the method are high in surface precision,low in cost, and high and stable in quality.
本发明公开了一种陶瓷型铸造的制作方法，具体工艺为：选择耐火材料‑选择粘结剂‑配电解水‑配陶瓷浆料‑灌浆‑起模‑喷烧‑焙烧，在配陶瓷浆料时，还加入有透气剂和促凝剂，同时灌浆后结胶时间可用促凝剂加入量来调整，小件可控制在4‑6秒，中大件控制在8‑15秒，起模时，时间约等于2倍结胶时，在结胶后5‑15分钟，焙烧温度在870°‑950℃，焙烧时间1‑3小时，以防止产生裂纹。本发明所加工出来的产品表面精度高，成本低，产品质量高且稳定。
