Fused alumina zirconia electrically fused brick pavement brick continuous casting sand mould

Abstract

The invention relates to a fused alumina zirconia electrically fused brick pavement brick continuous casting sand mould. According to the technical scheme, the sand mould comprises a bottom sand mould, multiple intermediate sand moulds which are sequentially piled up on the bottom sand mould and a top sand mould piled up on the intermediate sand mould at the topmost end, a feeding channel communicated with the inner cavity of the bottom sand mould is formed in the side surface of the bottom sand mould, the feeding channel extends upward and is connected with a public riser arranged above the top sand mould, and multiple material liquid circulating channels communicating the inner cavities are arranged between the upper part of the bottom sand mould and the intermediate sand mould arrangedat the bottom, between two adjacent intermediate sand moulds and between the uppermost intermediate sand mould and the top sand mould respectively. The fused alumina zirconia electrically fused brickpavement brick continuous casting sand mould provided by the invention has the advantages that multiple pavement bricks can be moulded during casting every time, casting efficiency is greatly improved, all the sand moulds share one riser, individual production of the riser is eliminated, sand mould processing efficiency is improved, and cost for enabling the riser to correspond to the sand mould is saved at the same time, so that the traditional shrinkage-free electrically fused brick casting thinking of 'one riser for one brick' is changed.

Description

technical field [0001] The invention relates to an electric fused brick sand mold, in particular to a zirconium corundum electric fused brick pavement brick continuous casting sand mold. Background technique [0002] The paving bricks of zirconium corundum fused bricks are used in the bottom part of the glass furnace. The common specification of the paving bricks in the horseshoe flame glass kiln is 100mm×400mm×600mm, and the common specification of the paving bricks in the float glass furnace is 75mm× 400mm×600mm, in the production of paving bricks, it belongs to the non-shrinkage casting form, and it is necessary to configure a non-shrinkage riser sand mold. The riser belongs to the funnel function or the solution in the riser feeds the brick body to make the brick body dense. effect. In terms of the use of the final product, only the brick body is the usable part, and the riser needs to be cut off and broken to be used as raw materials. The weights of the two kinds of p...
