Abstract

Bir sıvı dökme demir için kesintisiz kükürt giderme yöntemi olup; sıvı dökme demir işleme tertibatı içine kesintisiz olarak akan sıvı dökme demir içine bir kılıf ve bir astar içeren bir dolgulu tel enjekte edilmektedir. Söz konusu astar kükürt giderici bir ürün içermektedir; söz konusu kükürt giderici ürün metalik kalsiyumdur.It is a continuous desulfurization method for a liquid cast iron; A filled wire comprising a sheath and a liner is injected into the liquid cast iron flowing continuously into the liquid cast iron processing apparatus. The primer contains a desulfurizing product; said desulfurizing product is metallic calcium.
