What About Using Slag Ball?

1. How to determine the time and location of the Slag Ball?

When tapping to 3/4, the slag ball is dropped from the tapping point 500mm above the tapping surface with a special device, and the slag blocking effect is the best.

2. How to evaluate the effect of slag ball?

The effect of the slag ball can be evaluated by observing the shape of the molten steel in the steel port. When the slag blocking effect is good, the molten steel of the taphole should flow down in a ring shape. In addition, it can also be judged by the color of the slag.

3. What is the role of the groove on the slag ball? How to calculate?

The effect of the groove on the slag ball is that the slag ball facilitates the outflow of molten steel during the slag blocking process.

The formula for calculating the groove volume is: V1 = area of the groove * slot length = πr2 / 2 * L

4. How to evaluate the performance of the slag ball after use?

The effect of the slag ball after use can be assessed by the thickness of the slag layer in the ladle and the alloy yield. The thickness of the slag layer is small, the alloy yield is high, and the slag blocking effect is good.

5. What data needs to be recorded in the field test?

The data to be recorded in the field test are: tapping temperature, slag ball use time, slag layer thickness, alloy yield and so on.
