摘要： The disclosure is based on the idea of providing a pipe flange coupling device (3), which is attachable in connection with a first pipe (1) of a first pipe flange (1a), having pawls (6) engaging a second pipe flange (2a) of a second pipe (2). The pawls (6) are fixed to a spindle (5) retractable by a translation arrangement so as to pull the second pipe flange (2a) against the first pipe flange (1a). More particularly, the translation arrangement is configured such that, when the flanged pipes (1, 2) are coupled and the pawls (6) are retracted, a force exerted on the pawls (6) towards the extended position is transmitted via the translation arrangement against a mechanical stopper. Moreover, the translation arrangement is biased such that the translation arrangement must work against this bias in order to extend the pawls and release the flanged pipes (1, 2) coupled to each other.

摘要： The invention relates to a method for injecting, into the bottom of a molten bath located in a metallurgical vessel (1), process gases or mixtures thereof and/or of fine-grained metallic and/or non-metallic solids or mixtures thereof using cooled nozzles (3) which are located under the bath. According to the invention, a gas stream consisting of protective gas which completely surrounds the stream of the injected process gases and/or solids is fed into the metallurgical vessel (1) in order to cool said nozzles (3), whereby the gas stream consisting of protective gas is controlled according to cooling conditions. In order to extend the serviceable life of the lining (4) of the metallurgical vessel (1) with fireproof material and to ensure the sufficient supply of process gases and/or solids into the molten bath, the quantity of protective gas fed to a nozzle (3) is controlled using combined quantity control and pressure and/or temperature control. This is accomplished in that at least one control loop ensures a base protective gas quantity with a quantity control, and at least one additional control loop controls fluctuations of the demand for protective gas for optimally cooling the nozzles (3) and keeping the same open during a process according to the pressure of the protective gas occurring on the nozzle (3) and/or according to the temperature of the molten bath (7) located in the metallurgical vessel (1).

摘要：本发明公开了一种利于炉底维护的溅渣补炉方法，当转炉炉底炉衬被侵蚀高度未超过第一侵蚀高度时，采用先倒渣后溅渣工艺对转炉实施溅渣操作；当转炉炉底炉衬被侵蚀高度超过第一侵蚀高度但未超过第二侵蚀高度时，采用调渣溅渣工艺对转炉实施溅渣操作；当转炉炉底炉衬被侵蚀高度超过第二侵蚀高度时，采用补炉料快补炉工艺对转炉实施补炉操作；在溅渣、补炉过程中，对转炉实施底吹供气，供气流量随时间逐步调整。在采用调渣溅渣工艺后，判断底吹风口处是否有凹陷，若有凹陷，则采用补炉料快补炉工艺对转炉实施补炉操作。本发明的溅渣补炉方法采用与转炉生产节奏相匹配的转炉溅渣和补炉工艺，提升了转炉底吹效率，延长了底吹风口寿命。
