Ceramic runner tube for GM casting and production method thereof
The invention discloses a ceramic runner tube for GM casting. The ceramic runner tube is mainly composed of main materials, bauxite and Qing clay, and high-aluminum grogs, used for fine adjustment. The ceramic runner tube is sintered at high temperature by means of ceramic production. The batch is fully finely ground, stock has no graded rough particles, and porosity of a product is reasonably high; more importantly, air pores are evenly distributed, and inevitably the product is high in density, mechanical strength, stripping resistance and thermal shock resistance; a main crystal phase is a mullite phase with well-developed crystal, a secondary crystal phase is a corundum phase, and the requirements on the ceramic runner tubes for high-end casting. The invention further discloses a production method of the ceramic runner tube.
