Embodiment 1

[0016] According to the required amount of one kilogram of binder per ton of casting mold, 80 parts of quartz powder with a particle size of ≥180 mesh, 0.8 part of 400# Portland cement, 4 parts of light clay powder, and 0.2 part of sodium fluorosilicate Put it on the steel plate and mix it for 3-5 minutes until it reaches a uniform state, then put the mixed material into the plastic bucket, add 12 parts of 40 Baume degree water glass, stir it with a wooden stick for 2-3 minutes, and then it can be used for sticking. figure 2 Shown is the whole model bonded with this adhesive. The model is simple to manufacture, high in strength, convenient in casting, and accurate in finished product size, which reduces the amount of cutting and grinding in the later stage.

Embodiment 2

[0018] According to the required amount of one kilogram of binder per ton of casting mold, 88.8 parts of quartz powder with a particle size ≥ 180 mesh, 1 part of 400# Portland cement, 5 parts of light clay powder, and 0.3 parts of sodium fluorosilicate Put it on a special steel plate and mix it for 3-5 minutes until it reaches a uniform state, then put the mixed material into the plastic bucket, add 14 parts of 40 Baume degree water glass, stir it with a wooden stick for 2-3 minutes, and then it can be used for sticking. . figure 2 Shown is the whole model bonded with this adhesive. The model is simple to manufacture, high in strength, convenient in casting, and accurate in finished product size, which reduces the amount of cutting and grinding in the later stage.

Embodiment 3

[0020] According to the required amount of one kilogram of binder per ton of casting mold, 90 parts of quartz powder with a particle size ≥ 180 mesh, 1.2 parts of 400# Portland cement, 6 parts of light clay powder, and 0.4 parts of sodium fluorosilicate Put it on a special steel plate and mix it for 3-5 minutes until it reaches a uniform state, then put the mixed material into the plastic bucket, add 15 parts of 40 Baume degree water glass, stir it with a wooden stick for 2-3 minutes, and then it can be used for sticking. . figure 2 Shown is the whole model bonded with this adhesive. In this way, the operation is simple and convenient during model making and casting, the strength of the model is greatly improved, the size of the finished product is more accurate, the dimensional accuracy of the product is guaranteed, the amount of cutting and grinding is reduced, and the inner quality and appearance of the product are greatly improved. Great improvement.

Abstract

The invention discloses a model adhesive for fused cast zircon-corundum bricks, which comprises the following raw materials by weight portions: 80-90 portions of quartz powder, 12-15 portions of soluble glass, 0.8-1.2 portions of Portland cement, 4-6 portions of light clay powder and 0.2-0.4 portions of sodium fluosilicate. The method for manufacturing the adhesive comprises the following steps: weighing the quartz powder, the Portland cement, the light clay powder and the sodium fluosilicate according the required quantities, evenly mixing on a steel plate, putting in an adhesive bucket, adding the soluble glass, and evenly stirring with a wood stick for use. According to the physicochemical properties of the corundum type, free-piece plates are adhered to form an integral shape by the adhesive according to the shape and the dimension of the product, so that the operation is simple and convenient when manufacturing and casing the model, the model strength is greatly enhanced, and thedimension of the finished product is more precise so as to ensure the dimension precision of the product, reduce the processing amount for cutting and grinding and greatly improve the internal qualityand the appearance of the product.

Description

technical field [0001] The invention relates to a model of a refractory product zirconium corundum brick, in particular to a model binder for melting and casting a zirconium corundum brick. Background technique [0002] Over the years, the models used for melting and casting zirconium corundum bricks are made into pieces with quartz sand and water glass binder, and then baked in a drying oven at 80-280°C to assemble the models, such as figure 1 As shown, fixing by bundling, branching, landfilling and other methods is not only difficult to operate, but also easily deformed when the brick body is fired, which affects the quality of the finished brick. Contents of the invention [0003] The object of the present invention is to provide a model binder for fused-cast zirconium corundum bricks which combines loose model plates into one. [0004] To achieve the above object, the present invention can take the following technical solutions: [0005] The model binder of fused-cas...
