The impact of “dirt”
It is common to talk about the problems of cleaning refractory bricks and “dirt” with the impurities from the first casting jet that end up in the freshly cast ingot.
Everyone knows that the dirt from the first jet that arrives is not ideal, so improvement is essential. We cannot consider this element to be marginal in terms of quality when we look at, for example, a 50 x 100 mm diameter source tail that will end up in a 10-ton cast ingot.
We are here in a process of improving the quality of the cast product. The purpose concerns product quality and has no impact on improving the casting equipment.
THE OBJECTIVE: PREVENT DIRT FROM BEING INCORPORATED INTO THE INGOT
