Description

With the increasing requirements for steel quality, people have developed and applied many technologies to purify molten steel. However, the relatively pure molten steel may be re-contaminated after being injected into the tundish, especially during the pouring and pouring process of the tundish. After the roaster is lifted, the air quickly fills into the tundish, the covering agent is not added after pouring, the molten steel level in the tundish drops during the replacement of the ladle, and air enters the exposed part of the working layer of the tundish, thereby destroying the full protection pouring effect, causing secondary oxidation of the molten steel, and affecting the cleanliness of the molten steel.
