Silicon carbide sic bushing is a new type of high-tech and wear-resistant material in the world. It was made of high-purity silicon carbide powder, high-purity high-temperature carbon black and binders,by pouring, blanking, sintering, and sand-removing processes,made of a composite high wear product.
It is currently used as a bushing in mining equipment,such as copper, gold, iron ore,nickel ore and other in non-ferrous metals.It plays a role of high wear resistance,the wear life is more than 10 times that of conventional steel bushings and alumina bushing.
1.Application of sic bushing in the mining industry
For mine filling, the concentrate powder and tailings transportation has serious wear on the pipeline.The service life of the ore powder conveying pipeline used in the past is less than one year, and now choose silicon carbide bushings can increase the service life by more than 10 times.
2.Why silicon carbide linings are widely used in the mining industry?
Due to the wear resistance of ceramic tubes, the following is a comparison of wear resistance of ceramic tubes and other materials.
Comparison of wear resistance of silicon carbide bushings
|Sandblasting contrast test（SiC sand）||30%SiO2 mud slurry contrast test|
|Material||Reduced volume||Material||Reduced volume|
|97% alumina tube||0.0025||45steel||25|
|Silicon carbide bushing||0.0022||Silicon carbide bushing||3|
