Method for manufacturing fused zirconia corundum basin brick die

Abstract

The invention relates to a method for manufacturing a fused zirconia corundum basin brick die. The problems of difficult molding, low yield and raw material waste of a current special fused zirconia corundum basin brick are effectively solved. The structure of the fused zirconia corundum basin brick is that an inner core is arranged at the central position of an inner die; the inner die, the inner core and an outer die are concentrically arranged in the outer die; the inner core, the inner die and the outer die are made from resin sand; an exhaust conduit and a casting conduit which are communicated with a basin brick-shaped cavity formed between the inner die and the outer die are respectively arranged on the two sides of the outer die through casting openings; an exhaust dead head is formed in the upper part of the vertical exhaust conduit; a casting dead head is formed in the upper part of the vertical casting conduit; a loosen layer is arranged on a cutting line on the upper part of the outer die; a heat-preserving dead head is formed in the loosen layer; and on the two sides of a material basin, the exhaust conduit and the exhaust dead head are symmetrical with the casting conduit and the casting dead head. The characteristic that the resin sand is naturally collapsed under a high temperature is effectively used, and the utilization combining with a water glass sand dispersing plate is realized, the yield is high, color pollution of a product is avoided, and the post processing efficiency is improved.

Description

technical field [0001] The invention relates to a mould, in particular to a manufacturing method of a fused zirconia corundum brick mold for preparing fused zirconia corundum bricks. Background technique [0002] The production of fused zirconia corundum products is to pour the melted material liquid in the electric furnace into the sand mold, and then form it after cooling and solidifying. Due to its product characteristics, the production is affected by material properties, production technology and production equipment, so it is difficult to form some special-shaped products (more than 3 measuring scales), ultra-wide, ultra-long, ultra-thin, and disproportionate bricks , the production is very difficult, especially the specific type of pot brick, the surface shape is complex, the corners are many, the surface is many, the production process is complex, the yield is low, the formed product is prone to defects, the existing mold is difficult to form, and the production is d...
