Ceramic filter sieve for casting molten iron
The invention relates to the technical field of casting, and discloses a ceramic filter sieve for casting molten iron, hybrid silicon carbide and coal gangue composite powder are used as base materials, the base materials are mixed with water and a binder, then grinding is performed to obtain slurry, and the ceramic filter sieve is obtained through mold pressing, drying, demolding and sintering. The prepared ceramic filter sieve for casting molten iron can bear thermal shock from normal temperature to 1600 DEG C, is high in thermal conductivity and small in thermal expansion, and can filter the casting molten iron, remove impurities and improve the quality of the casting molten iron, so that the rejection rate of castings can be reduced. And the collision frequency of casting molten iron and the internal framework of the ceramic filter sieve can be increased, so that the filtering effect can be effectively improved.
本发明涉及铸造技术领域，且公开了一种铸造铁水用陶瓷过滤筛，以杂化碳化硅和煤矸石复合粉为基料，与水、粘结剂进行混合后，再进行研磨，得到浆料，经过压模，干燥，脱模，烧结，得到所述陶瓷过滤筛；本发明制备的铸造铁水用陶瓷过滤筛能够承受从常温到1600℃的热冲击，导热率高，热膨胀小，能够对铸造铁水进行过滤，去除夹杂，提高铸造铁水的质量，进而能够降低铸件的废品率本发明制备的陶瓷过滤筛内部结构更加复杂，能够增加铸造铁水与陶瓷过滤筛内部骨架的碰撞次数，从而，能够有效的提高了过滤效果。
