Αδιάβροχο Breathable Brick

Permeable bricks can be divided into ladle breathable bricks, converter (electric furnace) breathable bricks, intermediate frequency furnace breathable bricks, aluminum smelting breathable bricks and rotary anode furnace breathable bricks according to their applications.

One ladle breathable brick

The ladle breathable brick sits at the bottom of the ladle, and blows argon or nitrogen through the bottom of the breathable brick to cause the molten steel to agitate, which can partially remove the gas dissolved in the molten steel, and at the same time uniform composition, if used with a continuous casting machine, it can also adjust the molten steel The role of temperature.

Two converter (electric furnace) breathable bricks

The converter (electric furnace) breathable brick sits at the bottom of the converter (electric furnace), and argon is blown through the bottom of the breathable brick, which can effectively reduce the iron oxide content in the converter slag, increase the metal recovery rate, and effectively reduce the consumption of ferroalloys, so that the molten steel in the converter can be effectively reduced. The temperature and composition are more uniform.

Three ventilating bricks for intermediate frequency furnace

The intermediate frequency furnace ventilated bricks can reduce the content of various inclusions in the intermediate frequency furnace smelting process at low cost and high efficiency, improve the grade of castings, and improve economic benefits. Breathable bricks can achieve the purpose of degassing, decarburizing and removing oxide inclusions in molten steel. The most important thing is that by blowing argon into the chromium-containing molten steel, while decarburizing, the chromium content of the molten steel will not change. To

Four aluminum smelting breathable brick

Breathable bricks have been widely used in the aluminum smelting industry, and can be used in launders, degassing filter boxes, aluminum liquid transfer packages, holding furnaces and melting furnaces. It can greatly improve the thermal cycle, make the temperature in the furnace more uniform, increase the dissolution rate, reduce the precipitation of aluminum slag, and improve the exhaust efficiency.

Five air brick for rotary anode furnace

Breathable bricks for rotary anode furnaces have gradually become popular in China in recent years. The rotary anode furnace adopts bottom blowing nitrogen. The ventilating brick can effectively shorten the smelting time of a single furnace, has high thermal efficiency, and handles a large amount of cold material. It can make the temperature in the furnace more uniform, reduce the dead zone, and avoid the occurrence of nodules in the furnace. At the same time, impurities can be effectively removed, the quality of the anode plate is improved, the composition of the anode copper is optimized, and the taste of copper liquid is greatly improved.
