日本钢公司堺厂开发了一种用于转炉炉气收集(OG)的不可分离式系统。通过转炉炉口和气体收集部分之间缝隙的完全闭合,阻止了渣子泡沫外溢、钢水喷溅和 LD 炉气(LDG)的燃烧损失,见图1。.性的氧枪亲纷集气4』议护口与军裙之月的双层闸板烟草的升降气缸外部封旧气缸LU.转护的1 ION也3提高到120Nm3.这个数量可以认为是 Nippon Steel, a Japanese steel company, has developed a non-separable system for converter gas collection (OG). Through the complete closure of the gap between the converter mouth and the gas collecting part, slag foam outflow, molten steel splashing and LD combustion loss are prevented (see Fig. 1). . Sexual oxygen guns have gathered gas 4 "mouth and arms to protect the mouth of the double-decker racking tobacco lifting cylinder external seal old cylinder LU. The 1 ION transfer protection also increased to 120Nm3. This number can be considered
