摘要： A method for operating a converter on the basis of a direct observation of the slag-forming conditions in a vessel interior.A device for observing the vessel-interior light is disposed in a throughhole extending through the side wall of a top-blowing or top- and bottom-blowing converter to reach the vessel interior. The converter operation can be carried out at a high accuracy of the slag-amount control on the basis of this observation.

摘要： An exhaust-gas treatment system for a sealed-type converter has a hood for guiding converter exhaust gas and is provided with an emergency air admission valve device communicatively connected to the hood and comprising, essentially, a valve seat communicating with a valve entrance for inflow of outside air, a valve body normally in valve closed position against the valve seat to shut off air from entering the hood, and a valve body locking device functioning to normally hold the valve body in locked state in the valve closed position and operating in an emergency to release the valve body, which thereupon separates away from the valve seat thereby to admit outside air into the hood to prevent occurrence of negative pressure in the hood.
摘要翻译：用于密封型转换器的废气处理系统具有用于引导转换器废气的罩，并且设置有通气连接到罩的应急进气阀装置，其基本上包括与用于流入的阀入口连通的阀座外部空气的阀体，通常处于阀关闭位置以抵靠阀座以截止空气进入罩的阀体;以及阀体锁定装置，其功能是将阀体正常地保持在处于闭合位置的锁定状态并以紧急释放阀体，其随后与阀座分离，从而允许外部空气进入罩内，以防止发动机罩内产生负压。

摘要： Treatment of molten steel in a ladle, which comprises blowing inert gas into the ladle from its bottom, partially immersing a receptacle which covers the portion of the molten steel where the inert gas bubbles out and maintain non-oxidizing atmospheres within the receptacle with the gas so as to prevent oxidation of the molten steel by the slag.
摘要翻译：在钢包中处理钢水，其中包括从其底部向惰性气体中吹入惰性气体，部分地浸没一个容器，该容器覆盖钢水部分，惰性气体在该位置发生气泡，并在气体内保持非氧化气氛以防止熔渣对钢水的氧化。
