Abstract

The invention discloses a double-ventilation-element bottom blowing brick device, belonging to the technical field of steelmaking. The double-ventilation-element bottom blowing brick device comprises an entire type bottom brick (1), double-ventilation core bodies (2), a ventilation connecting device (3), and a lifting lug assembly (4); the double-ventilation core bodies (2) are coated in the entire type bottom brick (1), and the entire type bottom brick (1) is connected with a gas connecting device on a metallurgical liquid container through the ventilation connecting device (3); the lifting lug assembly (4) and the entire type bottom brick (1) are connected and used for lifting the double-ventilation-element bottom-blowing brick device. The double-ventilation-element bottom-blowing brick device has the advantages of being applicable to meeting the high-flow gas supply requirement, the strict requirement of a special refining device on a bottom blowing system, especially the requirement of a small-capacity ladle distribution hood type refining device on the bottom blowing brick distribution mode, and being simple to produce, convenient to operate, easy to produce and realize, and capable of meeting the usage safety requirement.

Description

technical field [0001] The invention belongs to the technical field of steelmaking, and particularly relates to a double-ventilating-element bottom blowing brick device, which is suitable for determining the layout design of the bottom blowing bricks in a large-flow gas supply environment and a small-capacity ladle arrangement bell-type refining device. Background technique [0002] At present, large and medium-sized iron and steel enterprises in the metallurgical manufacturing industry need to produce high value-added products, technology and cost requirements. Refining devices are widely used in iron and steel enterprises. Ladle blowing argon is a simple and effective method of refining outside the furnace, and it is compatible with various refining devices. Matching to achieve a good treatment effect, in order to achieve uniform temperature and composition of molten steel and the purpose of purifying molten steel. [0003] There are two ways to blow argon in the ladle, on...
