When the electric furnace gas discharges to form an arc, the energy is very concentrated, and the arc zone temperature is above 3000 ℃. For electric arc steelmaking furnaces, the bottom and walls of the furnace are built with alkaline or acidic refractory materials. During the steelmaking process, the working layer of the inner lining…
Functional refractories for continuous casting refer to the integral stopper, (ladle) shroud and immersion nozzle, which are called the three major pieces of continuous casting. Some people also include the ladle slide plate, the tundish slide plate, and the tundish top nozzle. Carbon refractories are commonly known as carbon-bonded refractories. In fact, the flow control…
Before talking about the reasons for the damage of the ladle slide, we first have a general understanding of the sliding mechanism of the ladle. The structure diagram of the nozzle and the sliding plate is as follows: The ladle sliding nozzle is composed of a sliding mechanism, an upper nozzle, a sliding plate,…
