Problems solved by technology

The ladle with sticky slag is difficult to clean, and safety accidents are prone to occur
[0003] After the existing anti-adhesive slag spray coating is sprayed, the anti-adhesive isolation protective film formed has a large thickness and low adhesion, which is easy to fall off and has poor protection effect on iron ladles.
Furthermore, the production cost of spray coating is high and the economic benefit is poor.

Abstract

The invention provides molten-slag-resistant spray paint for a ladle. The molten-slag-resistant spray paint comprises the following components in percentage by weight: 70-80 percent of aggregate, 16-25 percent of a bonding agent, 1-10 percent of a molten-slag-resistant functional additive and 0.01-1 percent of an additional additive, wherein the bonding agent is a composite bonding agent, and comprises silica powder, silicate cement, sodium silicate powder and bentonite. A method for applying the spray paint comprises the following steps: firstly, preparing a mixture in the weight ratio; secondly, adding water in an amount of 5-8 percent based on the weight of the mixture under strong stirring; and lastly, spraying the mixture onto a molten slag resisting position on the ladle through a spray gun. Compared with the prior art, the molten-slag-resistant spray paint provided by the invention has the advantages of high strength, high molten slag resistance, molten slag erosion resistance, oxidation resistance and high thermal shock resistance. Moreover, a waste sliding plate reclaimed material is taken as a main component for the aggregate of the molten-slag-resistant spray paint, so that the production cost of the molten-slag-resistant spray paint is lowered greatly, and high comprehensive benefit is achieved.

Description

technical field [0001] The invention relates to the technical field of spray paint, in particular to an anti-sticking slag spray paint for iron ladle and its application method. Background technique [0002] The molten iron is poured into the converter through the reverse transport of the ladle. During the use of the ladle, the brick lining is eroded by high temperature, and it is easy to stick to slag and iron, which shortens the service life of the ladle. There are two main methods of sticking slag and iron in the ladle: one is that the molten iron and slag are directly fused with the castable along the ladle, react with each other, and finally merge into one; the other is that the molten iron slag solidifies in the Package along the castable. The ladle with sticky slag is difficult to clean up, which is prone to safety accidents. [0003] After the existing anti-adhesive slag spray coating is sprayed, the anti-adhesive isolation protective film formed has a large thickn...
