Mould for preparing electric smelting zirconium adamantine spar rotating cylinder brick

Abstract

The invention relates to a mould for preparing an electric smelting zirconium adamantine spar rotating cylinder brick, which can effectively solve the problem that the existing special type electric smelting zirconium adamantine spar brick is difficult in molding, poor in molding quality and large in production difficulties. The method is that an outer mould is placed outside a lower inner core, the outer mould and the lower inner core are homocentrically arranged on a bottom fixing piece, an upper inner core is homocentrically arranged on the lower inner core, the lower inner core, the upperinner core and the upper portion of the outer mould are fixed together through upper fixing pieces, the bottom fixing piece is fixed on a base, a pouring conduit which is vertical to the base and parallel to the lower inner core is arranged on the upper portion of one side of the bottom fixing piece, the pouring conduit is communicated with a space on the upper portion of the base, a pouring deadhead is arranged on the upper portion of the pouring conduit, and a feeding head homocentric with the upper inner core is arranged outside the upper inner core and arranged above the upper fixing pieces. The mould for preparing the electric smelting zirconium adamantine spar rotating cylinder brick effectively uses characteristics that resin sands are hard and dry and complex moulds are integrally made, guarantees product accuracy, uses water-glass sands and white corundum, improves rate of finished products, avoids color and luster pollution of products, and improves later-stage processing efficiency.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for preparing fused zirconia corundum rotary 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 yield rate is low, and the formed products are prone to defects. Among them, the rotary drum brick is a special product, the production process is complicated, the existing mold is difficult to shape, and the quality of the molding is poor, and the production is difficult. It is imperative. Contents of the invention [0003] In view of the above ...
