Abstract

The invention discloses a high-property spraying paint for a slag pot and a preparation method thereof. The high-property spraying paint for the slag pot comprises a main material and additives, wherein the main material is prepared from the following raw materials in percentage by weight: 10 to 20% of mill-cleared waste particle, 70 to 80% of mill-cleared waste fine powder, 1 to 5% of silicon micropowder and 5 to 8% of Guangxi clay; the weight of the additive is 0.2 to 2% of that of the main material. The high-property spraying paint for the slag pot, disclosed by the invention, is better inall properties, has the characteristics of less than 8% of resilience rate, good adhesion property, no stickiness to slag, good slag-erosion resistance and easy slag overturning, and also has the beneficial effects that the service life of the pot can be prolonged, the manual clearing can be reduced, the economic and social benefits are obvious, and a pot returning rate is increased by 20% or more.

Description

technical field [0001] The invention belongs to the field of refractory unshaped refractory products, and in particular relates to a high-performance slag tank spray coating and a preparation method thereof. Background technique [0002] The slag tank is a container used to hold the high-temperature slag produced in the iron and steel smelting process. The operating temperature is 1200-1400°C, and it is used for short-distance transportation in the production process of steel mills. In order to prevent the molten slag and residual molten steel from directly contacting the slag tank body during the filling process and cause the slag tank to stick to death, facilitate slag turning, increase the return rate of the tank, effectively reduce the damage of the slag tank, and maintain a virtuous cycle in the production process, steel mills use spray The method of coating is used to protect the slag tank and improve the service life of the tank. [0003] At present, most of the slag...
