摘要： A vessel, such as a ladle or converter has a wall having extending therethrough a bore. A tube is fixed in a gas tight manner within the bore. The tube has therethrough a cylindrical passage. At least one gas permeable insert is fitted in a gas tight manner within the passage. The insert may be a pre-shaped insert or may be a mass tamped and packed into the passage. The insert may be replaced by drilling the insert from the passage of the tube and fitting a new insert within the passage. A gas connection is connected to the outer end of the tube to supply gas into the tube and through the insert into the interior of the vessel.

摘要： A tap spout, particularly for allowing molten metal to be discharged from oxygen-steel converters, includes a replaceable unit including a tubular wear lining and a jointing layer secured thereto. An inner lining of the tap spout may thus be repaired with relatively simple maintenance work by removing the inner lining and subsequently inserting the replaceable unit into an outer lining of the tap spout to form a new inner lining of the tap spout. The replaceable unit is adapted to facilitate either a press fit, and in particular, a fit ensured by axial compression of the jointing layer, or an expansion fit with the outer lining to secure the replaceable unit therein.
摘要翻译：特别是用于允许熔融金属从氧 - 钢转炉排出的排水口包括可更换单元，其包括管状耐磨衬里和固定在其上的接合层。因此，可以通过移除内衬并随后将可更换单元插入到排水口的外衬里中以相对简单的维护工作来修理排水口的内衬，以形成排水口的新内衬。可替换单元适于促进压配合，特别是通过接合层的轴向压缩确保的配合，或者与外衬的膨胀配合以将可更换单元固定在其中。

摘要： The invention relates to an arrangement of a blow pipe containing at least one gas permeable refractory plug. The blow pipe is disposed in the wall of a melt-containing vessel for the introduction of gases into the vessel. The blow pipe may be a metallic or ceramic pipe which passes through the vessel wall, and is longitudinally slidable in the vessel wall. Additional pieces of blow pipe in the form of pipe inserts can be added onto the blow pipe, which is in the wall vessel, to replenish the pipe insert material as it is consumed inside the vessel. The arrangement may include mechanical, pneumatic or hydraulic means to advance the pipe inserts into the vessel. The pipe inserts forming the blow pipe may be coated with a suitable lubricant. Alternatively, the pipe inserts may be surrounded by fire-bricks which may contain graphite.
摘要翻译：本发明涉及一种包含至少一个透气性耐火塞的吹管的布置。吹塑管设置在用于将气体引入容器中的含熔融容器的壁中。吹管可以是穿过容器壁的金属或陶瓷管，并且可以在容器壁中纵向滑动。在管状插入件形式的附加吹塑管件可以被添加到位于壁容器中的吹管上，以便当其在容器内消耗时补充管插入材料。该装置可以包括用于将管插入件推进到容器中的机械，气动或液压装置。形成吹塑管的管道插入件可以涂覆合适的润滑剂。或者，管道插入件可以包含可能包含石墨的火砖。

摘要： A refractory bottom lining has extending therethrough at least one inclined decarburization or refining nozzle or tuyere. Surrounding the nozzle is an outer perforate brick having a hole therethrough. An inner brick fits within the hole of the outer brick and has a bore which is inclined at the same angle of inclination as the nozzle. The nozzle extends through the bore.
