Problems solved by technology

The process of this method is cumbersome, and because the residues in the visible pores of the skateboard are pitch carbon, the actual use of the product, due to the poor oxidation resistance of pitch carbon, will cause board surface erosion and roughening, which is not conducive to the improvement of the number of skateboards

Embodiment 1

[0020] During the impregnation process, the mixed liquid enters the vacuum oil immersion chamber, and the liquid can enter the interior of the slide tile to the maximum extent by pumping to 45Pa and pressurizing to 1.3MPa to effectively fill the pores.

[0021] During the heat treatment process, the pitch is carbonized, and the micropowder component in the mixed liquid is itself solid, and its residual amount is 100% in this temperature environment.

[0022] As a result, the apparent porosity of the skateboard tiles can be reduced to less than 3% through this process once.

[0023] Due to the high-efficiency anti-oxidation, anti-corrosion, and anti-slag materials used in the micropowder material composition, during use, the sliding plate of the same material is processed according to the technical process of the present invention, and the number of times of use increases twice on average.

[0024] Example 2

Embodiment 2

[0026] During the impregnation process, the mixed liquid enters the vacuum oil immersion chamber, and the liquid can enter the interior of the slide tile to the maximum extent by pumping to 43Pa and pressurizing to 1.4MPa to effectively fill the pores.

[0027] During the heat treatment process, the pitch is carbonized, and the micropowder component in the mixed liquid is itself solid, and its residual amount is 100% in this temperature environment.

[0028] Therefore, the apparent porosity of the slide tile can be reduced to less than 2.9% through this process once.

[0029] Due to the high-efficiency anti-oxidation, anti-corrosion, and anti-slag materials used in the micropowder material composition, during use, the sliding plate of the same material is processed according to the technical process of the present invention, and the number of times of use is increased by more than two times on average.

[0030] Example 3

Embodiment 3

[0032] During the impregnation process, the mixed liquid enters the vacuum oil immersion chamber. By pumping 46Pa and pressurizing 1.5MPa, the liquid can enter the interior of the skateboard tile to the maximum extent and effectively fill the pores.

[0033] During the heat treatment process, the pitch is carbonized, and the micropowder component in the mixed liquid is itself solid, and its residual amount is 100% in this temperature environment.

[0034] Therefore, the apparent porosity of the slide tile can be reduced to less than 3.0% through this process once.

[0035] Due to the high-efficiency anti-oxidation, anti-corrosion, and anti-slag materials used in the micropowder material composition, during use, the sliding plate of the same material is processed according to the technical process of the present invention, and the number of times of use is increased by more than two times on average.

Abstract

The invention discloses an impregnation process for sliding tiles. In the impregnation process of the product, the micropowder is added to the medium temperature bitumen for impregnation. In the asphalt storage tank, the asphalt solution and the micropowder are thoroughly mixed through the electromagnetic stirring device to form a mixture of asphalt and micropowder. When the skateboard bricks are impregnated in the vacuum oil immersion system, the mixed solution enters the visible pores of the skateboard and passes through In the subsequent process, after the mixture is cooled and heat-treated to carbonize the pitch, the residue of the mixture significantly reduces the apparent porosity of the slide, and the addition of micro powder effectively improves the performance of the slide, thereby increasing the number of times the slide is used and reducing the steel refractory per ton consumption cost.

Description

technical field [0001] The invention relates to the technical field of production technology of refractory products, in particular to a new treatment process of functional refractory sliding bricks for controlling the flow of molten steel in the steelmaking process, specifically a sliding brick impregnation process. Background technique [0002] As an important part of flow control in the steelmaking process, slide bricks have high production process requirements. The number of consecutive uses of slide plates is directly related to the consumption cost of refractory materials per ton of steel, the labor intensity of on-site workers, and the continuity of steelmaking rhythm. High-grade skateboard bricks generally have to undergo firing treatment. Due to the complex physical and chemical changes and reactions between various components, the fired products have a relatively high porosity, generally 10%-20%. It must be impregnated to reduce apparent porosity. The traditional t...
