The characteristics and advantages of wear resistant castings
As is known to all, wear and tear caused a lot of energy and raw materials consumption, they are the main failure forms of a workpiece. Because of the high molecular weight of wear resistant castings, they have excellent comprehensive performance such as wear resistance, impact resistance, corrosion resistance, self-lubrication, the coming of wear resistant castings can effectively solve the problem. Wear-resistant castings had been listed as national key scientific and technological achievements promotion plan by the ministry of science and technology countries KeJi words (2000) 056 document in 2001. Because of the mature and stable technology, Wear-resistant castings have been widely used in many fields. They can provide protection to wear occasions or wear parts, make the equipment have longer life, reduce maintenance overhaul downtime, and also reduce corresponding capital spending.
The advantages of wear resistant castings:
1. High wear resistance.
2. Good impact resistance.
3. Good resistance performance to high temperature.
4. Good connection performance. Wear resistant castings have toughness and plasticity, offering resistance to the strength of the external force.
Wear-resistant castings have high wear resistance and good impact resistance, so they can be cut, bended, and weided. And they can connect with other structure by welding, plug welding and bolt connection, and are time saving, convenient in maintenance process. Wear-resistant castings are widely used in metallurgy, coal, cement, power, glass, mining, building materials, tiles and other industries. Compared with other materials, Wear-resistant castings have a high cost performance, and have been favored by more and more industries and factories.
