紹介され、使用されるようになってきた。Conventionally, during steel ingot making and continuous casting, for example, synthetic wollastonite, fly ash, etc.
The mold additive used in the form of a powder was used up, or the work environment was unfavorable due to the generation of dust at 11 o'clock. It has started to be done.

力[たな厄介な問題か出現している。In some ways, these shapes do have the advantage of being less dusty in the working environment, but because of their shape, they tend to have a high specific gravity, so their melting speed is slow, and when they come in contact with molten steel, It does not melt quickly and may cause scratches on the steel ingot, has poor insulation and heat retention effect, may cause scratches on the steel ingot due to bare hot water, and may even cause cracks in the casting iron due to the protrusion of the hot water surface. A troubling problem has emerged.
