The present application discloses a method for preparing a flow channel component of a pouring system, comprising: preparation of a first slurry: mixing organic fibers, a first refractory material and a first dispersant, and stirring uniformly to form a first slurry; Forming of the component embryo: put the first slurry into the first slurry pool, put the molding die into the first slurry pool to form the first component embryo; preparation of the second slurry: the inorganic fiber, the second refractory And the second dispersant is mixed, stirred evenly to form the second slurry; the molding of the second component embryo: put the second slurry into the second slurry pool, put the first component embryo with the forming mold into the second In the slurry pool, the second component embryo body is formed; shaping: put the dried second component embryo body into the shaping machine mold, and perform high temperature hot pressing shaping; cutting and trimming: remove the second component embryo body after hot pressing and shaping The flash and excess parts form the runner components of the gating system. |
