结瘤堵塞物主要来自钢水内原已存在的高熔点夹杂,由于它们与钢水不润湿,在流经水口时,若遇上能满足(cosQ粒+cosθ料<0)式的水口材质,就会粘附到水口表面上。为了防止水口结瘤,除尽量降低高熔点固体颗粒的数量、改变其物化特性外,选用易被钢水润湿的水口材质,将是有效的。
Knot nodules mainly come from the existing high-melting inclusions in the molten steel. Because they are not wetted with molten steel, if they meet the nozzle material that satisfies the formula (cos Q + cos θ <0) when flowing through the nozzle, Adhesion to the nozzle surface. In order to prevent the nozzle nodules, in addition to minimize the number of high melting point solid particles, changing its physical and chemical properties, the use of water is easy to wet the nozzle material will be effective.
