Technology of the Wear Resistant Chromium Carbide Plates

As we all know, China's steel production has leapt to the world's first, the huge amount of iron ore, mining, transportation, crushing, sintering and other parts of the production equipment wear problems are increasingly present, high temperature conditions, the performance of the wear problem is particularly prominent. High temperature conditions, the key parts of the service life is short, frequent replacement, overhaul for a long time, not only spent a lot of manpower and resources, but also often cause shutdown, cut production, seriously affecting the continuity of production. China's metallurgical enterprises have long been troubled by them, so far, to solve the conditions of different conditions of wear problems, especially under high temperature conditions of wear and tear, is the general voice of the metallurgical enterprises.

For a long time, high temperature wear-resistant surfacing materials research and development and application of China's weak links, domestic high-temperature wear-resistant surfacing materials are limited, more typical cobalt-based alloy. Cobalt-based alloy is not only expensive, high cost, and can not fully meet the special requirements of metallurgical equipment requirements; abroad, in the same conditions, has been widely used high-performance iron-based wear-resistant surfacing alloy is very lack of early Developed and incorporated into the national standard D667 electrode, the use of temperature is limited to 500 ℃ below. So the high temperature wear of metallurgical equipment has not been a very good solution, which also led to China's high temperature wear conditions in the service parts of the surface wear-resistant surfacing materials rely mainly on imports. Imported high temperature wear-resistant surfacing material wear resistance is better than domestic, but there are two outstanding problems can not be resolved, one is expensive, high cost, the enterprise can not afford; the second is due to geographical relations, foreign enterprises pre-sale technology Support, after-sale technical services can not keep up, the purchase of materials can not be properly used and other reasons, resulting in the actual effect is not ideal.
