    摘要： In bottom blown oxygen steel making or in top and bottom blown combined oxygen steel making, a tip end of a tuyer immersed in molten steel is seriously damaged or melted away due to very high temperatures due to the vigorous combustion of carbon, manganese and so on by the oxygen blown into a furnace.In order to prevent such damage, hydrocarbon gas has been blown through space between an outer pipe and an inner pipe of a dual pipe tuyere or tuyeres, but such hydrocarbon gas rather excessively lowers the temperature of the molten metal adjacent to the tip end of the tuyere and often blocks the opening of the tuyere.Now, instead of blowing in hydrocarbon gas, particulate material such as limestone magnesite, dolomite and the mixture thereof are proposed to be blown into the molten metal in the decarburization steel making vessel carried by an innert gas, combustion gas, blast furnace gas, LD process gas and oxygen or a mixture of these gases.Particulate material mentioned above, when blown into the molten metal, increases the momentum of the gas flow, enhances a shielding effect, against high radiation heat by fire point, or further forms either a kind of protective layer or deposit of refractory mineral material at the tip of the tuyere thereby effectively preventing damage of the tuyere and lengthens the service life of the refining vessel.Addition of particulate material in continuously linearly or in stepwise manner has been proved to be effective for accomplishing the above-mentioned cooling and protecting effect of the particulate material.

    摘要翻译： 在底吹氧钢制造或顶吹和底吹组合氧钢制造中，浸入钢水中的风嘴的尖端由于碳，锰等的剧烈燃烧而导致非常高的温度严重损坏或熔化 通过吹入炉中的氧气。 为了防止这种损坏，烃气已经吹过双管风口或风口的外管和内管之间的空间，但是这样的烃气体相当地过低地降低了与熔池的尖端相邻的熔融金属的温度 风口并经常阻塞风口的开启。 现在，代替吹入烃类气体，提出了诸如石灰石菱镁矿，白云石及其混合物的颗粒材料被吹入由内燃气体，燃烧气体，高炉煤气，LD所携带的脱碳炼钢容器中的熔融金属中 工艺气体和氧气或这些气体的混合物。 上述微粒材料在吹入熔融金属时，会增加气流的动量，增强屏蔽效果，防止火点发生高辐射热，或进一步形成一种保护层或难熔矿物材料的沉积物 从而有效地防止风口损坏，延长了精炼容器的使用寿命。 已经证明连续线性或逐步添加颗粒材料对于实现上述颗粒材料的冷却和保护效果是有效的。

    摘要： An apparatus for determining carbon contents in molten metal comprising an entrance chamber with an entry port in a side wall, a sampling chamber, a ring-shaped disk to be set between both chambers and a temperature sensing means which is protected from the flowing sample metal by a protective thermal insulation member, protruding through the entrance chamber to the sampling chamber. The molten metal flowing from the entry port is cooled by contacting with the protective thermal insulation member. The insulation member will turn to be a riser when the sample metal starts solidifying in the sampling chamber. Thus enabling precise rapid carbon determination and simultaneously offering appropriate specimen for spectrographic analysis.
