Problems solved by technology

[0002] The slag pots or slag pots used in converter steelmaking in iron and steel plants are easy to stick to slag. After sticking to the slag, the slag pots or slag pots need to be hoisted by aircraft to collide with each other. Due to the collision, the slag pots or slag pots are easily broken or deformed. Once the slag tank or slag basin breaks or deforms, it not only needs manual handling, but also is prone to accidents, and it will also cause a high probability of damage to the aircraft
The cost of repairing the aircraft is high, which affects production. In addition, the steel mill needs to purchase new slag basins and slag tanks every year, resulting in an increase in production costs
The existing anti-sticking slag coating is not ideal, the slag tank and the slag basin are not clean, and there are 30%-50% sticky slag, which is very unsafe

Abstract

The invention relates to an anti-slag-adhesion spray coating, which comprises the following raw materials in weight percent: 10%-13% of bauxite granules in grain size of 0-1mm, 20%-24% of bauxite powder in grain size of 325-800 meshes, 13%-18% of silica powder in grain size of 280-325 meshes, 35%-45% of silica powder in grain size of 600-1000 meshes, 1.5%-2.5% of metal silicon powder in grain size of 180-260 meshes, 0.5%-3% of zirconium oxide in grain size of 325-400 meshes, 2%-5% of silicon carbide in grain size of 180-280 meshes, 1.5%-3% of silica powder, 0.2%-0.5% of sodium tripolyphosphate, 0.3%-0.5% of sodium hexametaphosphate and 35%-40% of water. The anti-slag-adhesion spray coating has an excellent anti-slag-adhesion effect, a slag pot and a slag ladle are free from slag adhesion and the service life of the slag pot and the slag ladle is greatly prolonged.
