Abstract
The invention discloses an anti-adhesive slag agent for a tank mouth of a semi-steel tank, which contains the following components in percentage by weight: 20-40 percent of Al2O3, 15-35 percent of SiO2, less than 5 percent of SiC and 20-40 percent of H2O. The anti-adhesive slag agent has excellent slag resistance, and an isolation film for isolating slag is formed on the tank mouth of the semi-steel tank, so that the slag is easy to remove from the tank mouth of the semi-steel tank.
Description
Technical field
The present invention relates to a kind of anti-dry slag agent, specifically, relate to a kind of anti-dry slag agent for half steel jar jar mouth.
Background technology
Along with the increase of iron and steel output, common ore resources is more and more deficienter.Therefore, for the resource strategic concerns, increasing steel mill smelts with addition of vanadium titano-magnetite, because the special nature of vanadium iron magnetite, it brings more difficulty for the production direct motion, and wherein, half steel jar (hot-metal bottle) jar mouthful dry slag is distinct issues the most.
Behind half steel jar jar mouth dry slag, the quality of slack tank can increase, and makes to move on the half steel jar center of gravity, also can't guarantee safety in production when influencing the production direct motion.Simultaneously because dry slag is very hard and with jar mouth strong bonded, remove very difficultly, so have to remove overhaul in advance, cause short, turnover anxiety of half steel jar life-span and refractory consumption to increase.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and provide a kind of anti-dry slag agent for half steel jar jar mouth, this anti-dry slag agent to be specially adapted to the half steel jar jar mouth of splendid attire vanadium extraction by converter blowing molten steel.
According to an aspect of the present invention, prevent that the dry slag agent comprises the Al of 20%-40% by weight percentage
2O
3, 15%-35% SiO
2, the SiC less than 5% and 20%-40% H
2O.
According to embodiments of the invention, anti-dry slag agent can also comprise phosphate as binding agent.
According to embodiments of the invention, the SiO in the anti-dry slag agent
