Silicon carbide bricks in the non-ferrous metal industry application of real cases


In the non-ferrous metal industry, silicon carbide bricks are widely used in various smelting and processing equipment due to their excellent high temperature, wear and corrosion resistance. The following is a real case of silicon carbide brick application in the non-ferrous metal industry.

Case background
A large non-ferrous metal smelting enterprise is mainly engaged in smelting and processing of aluminium, zinc and other metals. During the production process, the enterprise faces multiple challenges such as high temperature, corrosion and abrasion, which puts forward extremely high requirements for the refractory materials of smelting equipment. Traditional refractory materials often suffer from poor thermal shock stability, easy flaking, short life span and other problems during use, which seriously affects production efficiency. Therefore, the enterprise decided to introduce silicon carbide bricks to replace the traditional refractory materials.

Application process
1、 Material selection: the enterprise chose a high-quality silicon carbide brick, whose main component is silicon carbide (SiC), with extremely high hardness and wear resistance. At the same time, the silicon carbide brick also has good thermal shock resistance and corrosion resistance, and can operate stably for a long time under the harsh environment of high temperature and corrosion.
2、 Equipment transformation: in smelting equipment, the enterprise will be silicon carbide bricks for furnace lining, furnace bottom, furnace wall and other key parts. Especially in aluminium smelting furnace and zinc smelting furnace, silicon carbide bricks are widely used as furnace lining materials to withstand high temperature and erosion of metal solutions.
3、Performance test: After the installation of silicon carbide bricks was completed, the enterprise carried out a comprehensive performance test. The test results show that the silicon carbide bricks have excellent stability and abrasion resistance at high temperatures, and can keep the normal operation of the equipment for a long time. At the same time, the silicon carbide brick also has good corrosion resistance, can effectively resist the erosion of metal solutions and corrosive gases.

Application effect
1、 Production efficiency: due to the excellent high temperature resistance and wear resistance of silicon carbide bricks, making the smelting equipment run more stable, production efficiency has been significantly improved.
2、Equipment life extension: the high hardness and wear resistance of silicon carbide brick makes its service life significantly longer than traditional refractory materials, reducing the replacement frequency and maintenance costs of equipment.
3、 Product quality enhancement: the corrosion resistance of silicon carbide bricks makes the metal solution in the smelting process more pure, improving the quality and purity of non-ferrous metal products.
4、Energy saving and emission reduction: the high thermal conductivity and good thermal stability of silicon carbide bricks help to reduce the heat loss in the smelting process, improve the efficiency of energy use, and achieve the goal of energy saving and emission reduction.

Case Summary
The practice of this large-scale non-ferrous metal smelting enterprise adopting silicon carbide bricks to replace traditional refractory materials shows that silicon carbide bricks have a wide range of application prospects in the non-ferrous metal industry. It not only improves production efficiency, prolongs equipment life, improves product quality, but also achieves the goal of energy saving and emission reduction. This successful case provides useful reference and inspiration for other non-ferrous metal smelting enterprises, and promotes the technological progress and sustainable development of the non-ferrous metal industry.
