摘要： A system that employs air to directly cool heat-accessible metallurgical vessels that are provided with separate annular supports, characterized in that air channels (6) are positioned on the outside of the annular support (5) with a number of air-injection pipes (7) distributed along the circumference and extending radially from the channels to the inner wall of the annular support, whereby outlets (8) slope up into the gap (3) between the annular support and the outer wall (1) of the metallurgical vessel, in that air is injected into the cooling system through one or both load-bearing connectors (4), and in that the difference in pressure within the system is less than 2000 mm H.sub.2 O and the air travels at less than 25 m/sec.

摘要： A method for producing steels of high purity and low gas content in steel mills and steel foundries comprises melting the steel with the desired alloying components in a ladle, directing an inert gas and oxygen mixture to the ladle with the molten steel to decarburize the steel in at least one phase, and carrying out decarburization, deoxidation and fining in separate operational steps without disturbing the coherence of the entire process cycle. The apparatus for carrying out the method includes a converter for the decarburization of the steel in several phases permitting successively a treatment with an air inert gas oxygen mixture and pure inert gas in gas amounts greatly varying from each other. In addition, a ladle is required for fine-flushing the steel succeeding the converter. The converter mouth advantageously has a mechanism permitting temporary reduction of the converter opening area. The converter also has a gas volume control and injection holes permitting a variation of the different gases to be injected. Injection holes are advantageously provided with individual controls. A ladle for the finished melt is lined with basic or neutral refractory materials so that the ladle lining can furnish no oxygen to the melt. A tapping ladle for the finished melt is advantageously lined with dolomite.
摘要翻译：一种在钢厂和钢铁铸造厂中生产高纯度和低含气量的钢的方法包括在钢包中用所需的合金成分熔炼钢，用钢水将惰性气体和氧气混合物引导到钢包中，使钢脱碳至少一个阶段，并且在不同的操作步骤中进行脱碳，脱氧和澄清，而不会干扰整个过程循环的一致性。用于实施该方法的装置包括用于多次脱碳的转炉，其允许连续地用空气惰性气体氧气混合物处理，并且以相当大的变化的气体量的纯惰性气体进行处理。此外，需要一个钢包来对转炉后的钢进行精细冲洗。转换器口有利地具有允许转换器开口面积临时减小的机构。该转换器还具有气体体积控制和允许注入不同气体变化的喷射孔。注射孔有利地设置有各自的控制。用于成品熔体的浇包用碱性或中性耐火材料衬里，使得钢包衬里不会向熔体提供氧气。用于成品熔体的攻丝钢包有利地衬有白云石。

摘要： An arresting device for preventing a steel making converter which is carried by a trunnion for moving itself during the blowing operation includes a rotatable bearing support for the trunnion or trunnion parts which extend from each side of the bessimer converter which carries a braking disc which is secured to at least one of the trunnion parts. The disc is advantageously mounted so as to be perpendicular to the axis of the trunnion. The trunnion is rotable on bearings carried on bearing supports on each side of the trunnion and a compresser mechanism including two braking jaws engage the disc from respective sides in braking contact therewith.
