Cemented Chute Wear Liners Wear Resistant Lining Applied In Mining Industry

Product Description

In the pulverizing, ash, dust removal, and coal conveying systems of coal-fired power plants, the equipment is constantly affected by factors such as friction, corrosion, collision, and impact of the medium during the operation of the equipment, and the system is extremely prone to leaks and cause environmental pollution. For this reason, various power plants have adopted different leakage control methods accordingly; among them, wear liners are an ideal leakage control material, and their wear resistance, practicability, and economy are superior to other wear-resistant materials.

Ceramic lining for power plant equipmentceramic wear resistant tiles

Product Features

The wear liner is a special corundum ceramic made of aluminum oxide as the main raw material, rare metal oxide as a flux, and sintered at a high temperature of 1700℃, and then combined with a special rubber and a high-strength inorganic binder. become.

(1) High hardness: its Rockwell hardness is 85-90.

(2) Good wear resistance and long service life: wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.

(3) Wide range of applications: wear liners include adhesive liners suitable for low-temperature environments, impact-resistant liners suitable for the impact of large pieces of materials, porcelain steel liners suitable for wind conveying, and high-speed operation suitable for dynamic operation. Of cemented ceramic fan blades.

Product Advantages

1. Wear-resistant ceramic liners are used more and more widely because of their super abrasion resistance. The reason is that the technology is mature and the cost is getting lower and lower; it is generally favored by users.

 

2. Since the wear-resistant liner has various series such as adhesive type, impact-resistant type, cemented type, etc., users can choose different types according to actual conditions.

 

3. As the adhesive is affected by certain conditions, its scope of application is still limited, but as new materials and technologies continue to emerge, the application will become wider and wider.

 

Application in power plants

Application in the pulverizing system: Most of the abrasion of the pulverizing system of coal-fired power plants is mainly caused by the collision, friction, and impact of the pulverized coal. The high-speed pulverized coal airflow is particularly serious to the pulverizing system equipment, especially to the outlet pipe of the coal mill, the elbow of the primary air pipe, and the inlet and outlet pipes of the coarse and fine powder separator. The methods adopted by various power plants for the treatment of the pulverizing system are the application of wear-resistant rubber series, although its wear resistance is superior to that of steel plate and has better strength and adhesion; its disadvantage is that the construction is more difficult and the cost is higher. The use of cast stone for anti-wear, its wear resistance is stronger than that of ordinary steel plates, but its major disadvantage is that it is brittle and heavy. It is not only restricted by the load safety system of the equipment system but also easily broken during installation. Also due to the thicker thickness and large volume of the cast stone slab, the flow cross-section of the equipment is reduced, the flow rate is increased, and the degree of wear is aggravated. Its service life is also difficult to compare with wear-resistant ceramic liners. The application of wear-resistant ceramic liners has an ideal effect and has been well-received by users. After the pulverizing system is used, it is not only wear-resistant and does not fall off, but also has no effect on the system. Its big advantage is that the construction is simple and the cost is low, showing its good development prospects.

 

Application in ash and slag system: In power plants that use hydraulic ash and slag removal systems, ash pumps, ash ditch nozzles, and other inlet and outlet pipe sections are easy-to-wear parts. According to on-site working conditions, sticky ceramics are more suitable. According to the usage of some power plants, the effect of these parts is very satisfactory. Maintenance personnel no longer frequently plug leaks and replace equipment.

 

Application in coal handling system: Most of the wear and tear of coal conveying system equipment is mainly abrasion and impact. The parts that are easy to wear are coal hoppers, tees, baffles, etc. The general anti-wear method used in power plants is the use of lining manganese steel plates, this method is not ideal, the reason is that the steel plates are not wear-resistant the service life is short (generally In about 6 months), and it is easy to be clogged by coal sticking; it brings maintenance workload to maintenance personnel. In the application of ultra-high molecular weight polyethylene board, although it is not easy to stick to coal and block; the wear resistance and impact resistance are not as good as steel plate, especially since the raw coal is easily squeezed into the joint between the liner and the cylinder wall, causing the liner to bulge and fall off. Some coal plants use ultra-high molecular weight polyethylene sheets, and the liner has fallen off many times, which has caused the coal machine chain to jam or even cause the chain to bend; it brings unnecessary maintenance workload to the maintenance personnel and also brings safety production Serious impact. Adhesive ceramic liner is a composite liner composed of ceramic liner that is pressed and embedded in special rubber, and its wear resistance, impact resistance, and smoothness of the inner wall are greatly improved. Judging from the use of some power plants, it is an ideal method for preventing wear and leakage.
