Problems solved by technology

This type of product is very difficult to form in fused refractory materials. The traditional sand mold design is a strip design, (each strip can be cut into five pieces) with a sand riser placed on it. Since the size of the hanging brick is small, the size of the sand riser is also large. It is relatively small, so that the casting speed cannot be effectively increased during the casting process, and the material liquid is sprinkled more. In addition, the cooling speed is faster during the annealing process, resulting in cracks in the hanging wall bricks, and the pass rate of the hanging wall bricks is not high.

Embodiment 1

[0019] (1) if figure 1 As shown, two wooden molds 2 are set on opposite sides of a flat steel plate 1 as the outer mold of the main body of the sand mold of the hanging wall brick, and then the hanging wall brick model 3 is placed at the center of the outer mold of the main body of the sand mold of the hanging wall brick, and then placed on the hanging wall The other opposite sides of the external mold of the main body of the brick sand mold are close to the hanging wall brick model 3 and a sealing plate (wooden board) is added to form a closed body with a closed perimeter and an open top, and then pass through the open top of the main outer mold of the hanging wall brick sand mold. The surface of the hanging wall brick model 3 is paved with 1mm thick paving sand; the preparation method of the paving sand is: mix 120-mesh silica sand and 8% sodium silicate with silica sand quality;

Embodiment 2

[0024] (1) Set two wooden molds on the opposite sides of a straight steel plate as the main outer mold of the hanging wall brick sand mold, then place the hanging wall brick model at the center of the main outer mold of the hanging wall brick sand mold, and then place the hanging wall brick sand mold on the hanging wall brick sand mold. The other opposite sides of the outer mold of the main body are attached to the hanging wall brick model and a sealing plate (wooden board) is added to form a closed body with a closed perimeter and an open top. Paving sand with a thickness of 3 mm is laid on the surface of the model; the preparation method of the paving sand is: mix 80 mesh silica sand and 9% sodium silicate with silica sand quality;

[0025] (2) Add material sand to the outer mold of the main body of the hanging wall brick sand mold and compact it (knock it firmly with a mallet) to ensure that the material sand is flush with the top of the main outer mold of the main body of t...

Embodiment 3

[0028] (1) Set two wooden molds on the opposite sides of a straight steel plate as the main outer mold of the hanging wall brick sand mold, then place the hanging wall brick model at the center of the main outer mold of the hanging wall brick sand mold, and then place the hanging wall brick sand mold on the hanging wall brick sand mold. The other opposite sides of the outer mold of the main body are attached to the hanging wall brick model and a sealing plate (wooden board) is added to form a closed body with a closed perimeter and an open top. Paving sand with a thickness of 2 mm is laid on the surface of the model; the preparation method of the paving sand is: mix 100 mesh silica sand and 8.5% sodium silicate with silica sand quality;

[0029] (2) Add material sand to the outer mold of the main body of the hanging wall brick sand mold and compact it (knock it firmly with a mallet) to ensure that the material sand is flush with the top of the main outer mold of the main body o...

Abstract

The invention discloses a method for manufacturing a sand mold of an AZS suspension wall brick. The method for manufacturing the sand mold of the AZS suspension wall brick comprises the steps that a suspension wall brick model is placed in a body outer mold of the sand mold of the suspension wall brick and is located in the center of the body outer mold of the sand mold of the suspension wall brick, a sand material is added to the body outer mold of the sand mold of the suspension wall brick and compressed, the plane of the sand material is higher than the upper surface of the suspension wall brick model, air holes are formed in the sand material, carbon dioxide is introduced into the air holes until the sand material is solidified, and then bodies of the sand mold of the suspension wall brick can be obtained by removing the body outer mold of the sand mold of the suspension wall brick and the suspension wall brick model; the sand mold of the suspension wall brick is constructed, wherein the sand mold of the suspension wall brick comprises a suspension wall brick sand mold base plate, suspension wall brick sand mold side plates are vertically arranged on the suspension wall brick sand mold base plate, and the bodies of the sand mold of the suspension wall brick are arranged on the two sides of the suspension wall brick sand mold side plates respectively. The method for manufacturing the sand mold of the AZS suspension wall brick has the advantages that the method is simple, using is convenient, raw materials are low in price and easy to obtain, when the sand mold manufactured with the method is used for casting, feeding is convenient, the amount of splashed feed liquid can be effectively reduced, the percentage of pass of manufactured suspension wall bricks is high, and waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of sand mold preparation, and in particular relates to a preparation method of AZS hanging wall brick sand mold. Background technique [0002] The surface shape of the fused AZS hanging wall brick is complex, the size of the lower part is large, the size of the upper part is small, and the size of the neck in the middle is smaller. This type of product is very difficult to form in fused refractory materials. The traditional sand mold design is a strip design, (each strip can be cut into five pieces) with a sand riser placed on it. Since the size of the hanging brick is small, the size of the sand riser is also large. It is relatively small, so that the casting speed cannot be effectively increased during the casting process, and the material liquid is sprinkled more, and the cooling rate is faster during the annealing process, resulting in cracks in the hanging wall tiles, and the pass rate of the hanging wa...
