Embodiment 1

[0025] The present invention provides a recycled corundum self-flowing castable, which includes the following components by weight percentage:

[0026]

[0027] During construction, 0.12% dispersant and 5% water of the total mass of the above corundum self-flowing castable should be added;

[0028] The dispersant is German P530 dispersant;

[0029] During construction, the mold needs to be supported, and the self-flowing castable mixed with water and dispersant is injected into the mold. The self-flowing castable can flow through any surface and fill any space, and quickly bond with the original leftover material without vibration. No noise, while reducing the labor intensity of workers.

Embodiment 2

[0031] The present invention provides a recycled corundum self-flowing castable, which includes the following components by weight percentage:

[0032]

[0033] It is necessary to add 0.05% dispersant and 5.5% water of the total mass of the above corundum self-flowing castable during construction;

[0034] During construction, the mold needs to be supported, and the self-flowing castable mixed with water and dispersant is injected into the mold. The self-flowing castable can flow through any surface and fill any space, and quickly bond with the original leftover material without vibration. No noise, while reducing the labor intensity of workers.

[0035] The dispersant is German P530 dispersant;

Embodiment 3

[0037] The present invention provides a recycled corundum self-flowing castable, which includes the following components by weight percentage:

[0038]

[0039]

[0040] During construction, it is necessary to add 0.2% dispersant and 6% water of the total mass of the above corundum self-flowing castable;

[0041] During construction, the mold needs to be supported, and the self-flowing castable mixed with water and dispersant is injected into the mold. The self-flowing castable can flow through any surface and fill any space, and quickly bond with the original leftover material without vibration. No noise, while reducing the labor intensity of workers.

[0042] The dispersant is a mixture of German P530 dispersant and sodium tripolyphosphate, wherein the weight percentage of German P530 dispersant and sodium tripolyphosphate is 3:2;

Abstract

The invention discloses a recovered corundum natural-flow castable and a construction method thereof. The recovered corundum natural-flow castable comprises the following components in percentage by weight: low-carbon brown fused alumina, recovered corundum, silicon carbide, silicon dioxide micropowder, pure calcium aluminate cement and high-purity zircon sand. A dispersing agent and water need to be added during construction. The construction method comprises the following steps: the mold is arranged, the water, dispersing agent and ready-mixed natural-flow castable are injected into the mold, and the material can flow across any surface and fill any space, and can be quickly bonded with the original remnant material. By using abundant recovered corundum, the method conforms to the strategic requirements of national sustainable development, and only a small amount of dispersing agent is added to regulate the properties, thereby effectively lowering the production cost and enhancing the flowability of the product.

Description

Technical field [0001] The invention relates to the technical field of refractory materials, in particular to a recycled corundum self-flowing castable and a construction method thereof. Background technique [0002] Self-flowing castable refers to low cement, ultra-low cement or cement refractory castables characterized by their fluidity after mixing. The refractory castables with this fluidity can flow and degas without applying external force, and there is no obvious segregation. . Since self-flowing castables have good flow characteristics, they have attracted people's attention in recent years. [0003] The corundum castable is suitable for filling the gap between the bottom of the ladle and the seat bricks, and the top of the electric furnace. It is used for repairing the damaged parts of refractory bricks or pouring when the high temperature furnace is subjected to different degrees of impact during feeding or discharging. Especially for non-stop production to repair furn...
