In the industrial field, the selection of high - performance refractory materials is crucial for the long - term operation of equipment. Chrome corundum bricks, as a key material to enhance the service life of industrial equipment, have attracted wide attention due to their excellent properties. This article will delve into the core technical performance of chrome corundum bricks and explain how they meet the needs of different industries.
Wear is a common problem in many industrial environments. Chrome corundum bricks have outstanding wear - resistant properties. According to industry research, in a high - speed material conveying system, chrome corundum bricks can reduce the wear rate by up to 70% compared with ordinary refractory materials. For example, in a cement plant, the use of chrome corundum bricks in the material chute can extend the service life of the chute from 6 months to 18 months, greatly reducing maintenance costs and downtime.
Thermal shock stability is one of the most important features of chrome corundum bricks. In industrial processes, equipment often experiences rapid temperature changes. Chrome corundum bricks can withstand sudden temperature changes from 1200°C to room temperature without cracking or spalling. In a steelmaking plant, the ladle lining made of chrome corundum bricks can endure more than 200 times of hot - cold cycles, ensuring the continuous and stable operation of the ladle.
In chemical, metallurgical and other industries, equipment is often exposed to acidic or alkaline environments. Chrome corundum bricks have excellent acid - base corrosion resistance. In a chemical plant producing phosphoric acid, the use of chrome corundum bricks in the reaction tank can resist the corrosion of strong acid for more than 5 years, while ordinary materials may need to be replaced within 1 - 2 years.
At high temperatures, materials may experience creep deformation, which affects the structural integrity of equipment. Chrome corundum bricks have low creep rates at high temperatures. Under a temperature of 1500°C and a load of 0.2MPa, the creep rate of chrome corundum bricks is less than 0.5% after 50 hours, ensuring the long - term stability of the refractory structure in high - temperature equipment.
By comparing with other similar products in the market, it is easy to find that chrome corundum bricks have obvious advantages in terms of performance and service life. These advantages make chrome corundum bricks widely used in various industries, such as steelmaking, cement, chemical, and glass industries.
