Description
Technical Field
The utility model relates to a technical field is made to glass melting furnace refractory material, specifically is a sand mould for electric smelting M silo brick.
Background
The material channel brick is mainly used for a distribution material channel of a glass kiln, generally adopts two materials of an electric melting AZS brick and an electric melting M brick, has better anti-corrosion performance of an electric melting M brick product because the temperature of the glass at the position is reduced, does not cause pollution to the glass, and is the most suitable material known at present. The price of the M trough brick is 50% higher than that of the AZS product, and the main reason is that the production process of the M trough brick is more complex and the probability of appearance defects of the brick material is higher. How to improve the yield of the M trough brick and reduce the production cost is very important for the popularization and the application of the high-quality refractory material.
The main appearance defect of the M trough brick is crack, and factors influencing the product quality comprise: formulation design, melting process, heat preservation annealing and casting mold design. Through the accumulation of the experiences of electric melting refractory material enterprises at home and abroad, the formula design, the melting process and the heat preservation annealing are basically greatly improved, but various enterprises in casting mold design are different, so that the production level of various enterprises is uneven.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a sand mould for electric smelting M silo brick, this sand mould can reduce the production of electric smelting M silo brick outward appearance crackle, improves the yields.
The utility model provides a technical scheme that its technical problem adopted is:
a sand mould for electrically melting M trough bricks comprises a rectangular casting shell, wherein a cubic inner mould is arranged in the casting shell, and four corners of the top of the inner mould are provided with round corners so that the shape of the M trough bricks is formed between the inner mould and the casting shell; a rectangular open slot is formed in the middle of the inner die along the longitudinal direction, through holes are formed in the inner die on two sides of the open slot along the longitudinal direction, steps are arranged at four corners of the top of the open slot, and a cover plate is arranged on each step; a thermal expansion joint is reserved between the cover plate and the vertical wall of the step, and a paperboard is filled in the thermal expansion joint;
a vertical supporting plate is arranged in the open slot and used for supporting the cover plate;

A vertical supporting plate 9 is arranged in the open slot 3, and the supporting plate 9 is used for supporting the cover plate 6.
And alumina powder 10 is filled in the open slot 3 and the through hole 4.
The casting shell 1, the inner mold 2 and the cover plate 6 are all made of white corundum.
The original structure of the solid inner mold is abandoned, the inner mold is provided with an open slot and a through hole, and is filled with an alumina powder heat-insulating medium, so that the heat-insulating effect is improved on the premise of ensuring the strength of the sand mold; the cover plate is designed uniquely, a thermal expansion gap is reserved, and an expansion space is reserved for expansion of the cover plate during casting, so that appearance cracks of the electric melting M trough brick are reduced, and the yield is improved. The cardboard 8 will disappear by carbon pulverization at the high temperature of casting, will not hinder the inflation of apron, and on the other hand also can guarantee the cleanness in the thermal expansion seam when not casting, avoids falling into impurity.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments according to the invention, and may be used in various other applications, including, but not limited to, industrial. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments by the technical entity of the present invention all still belong to the protection scope of the technical solution of the present invention.
