Problems solved by technology

[0002] In the steel (or copper, aluminum) smelting process of the prior art, the gas is supplied to the high-temperature molten steel through the ventilation element or the ventilation brick to uniform the composition and temperature of the molten steel, and promote the floating of impurities in the molten steel to improve the quality of the steel; However, the design of the ventilation slits of the existing ventilation elements or ventilation bricks is not reasonable enough, and steel seepage is prone to occur during actual use, resulting in clogging of the slits and low blow-through rate

Abstract

The invention provides a gas supply element, a composite gas supply brick and a manufacturing method of the composite gas supply brick. Gas supply channels, first anti-seepage anti-blockage channels and second anti-seepage anti-blockage channels are arranged in the gas supply element. The first anti-seepage anti-blockage channel is communicated with two or more other gas supply channels through fluid. The second anti-seepage anti-blockage channel is communicated with two or more other gas supply channels through fluid as well. Any two first anti-seepage anti-blockage channels and the corresponding second anti-seepage anti-blockage channel are communicated by the same gas supply channel through fluid. By the adoption of the gas supply element and the gas supply brick with the gas supply elements, steel seepage is not likely to happen in the actual use process, the gas supply channels are not blocked in the gas supply process, the blowing-through rate is high, the oxygen blowing amount is reduced, and the smelting cost is lowered; and due to the high blowing-through rate, the ablation amount of an air brick can be reduced as well, the service life of the air brick is prolonged, and the smelting cost is lowered.

Description

technical field [0001] The invention relates to the field of high-temperature smelting. More specifically, it relates to an air supply element for blowing air into a high-temperature melt, a composite air supply brick and a preparation method for the composite air supply brick. Background technique [0002] In the steel (or copper, aluminum) smelting process of the prior art, the gas is supplied to the high-temperature molten steel through the ventilation element or the ventilation brick to uniform the composition and temperature of the molten steel, and promote the floating of impurities in the molten steel to improve the quality of the steel; However, the design of the ventilation slits of the existing ventilation elements or ventilation bricks is not reasonable enough, and steel seepage is prone to occur during actual use, resulting in blockage of the slits and a low blow-through rate. In order to prevent the ventilation bricks from being blocked, the residual steel is m...
