How to cut alumina wear resistant tiles?

Alumina ceramic wear-resistant tiles/linings have been used in thermal power plants for a long time, mainly used in coal conveying pipelines. The pulverized coal wears off ordinary steel pipes very quickly, and most of them are repaired after being thoroughly ground. This is not a long-term solution. . However, wear-resistant pipes using alumina ceramic patches can be used for at least two years without wearing through if the design is reasonable. Although the first purchase is a bit more expensive, the price/performance ratio is very high.


Performance advantages of wear-resistant ceramic tiles/lining:


1. High hardness

As determined by the Shanghai Institute of Ceramics, Chinese Academy of Sciences, its Rockwell hardness is HRA80-90, which is second only to diamond and far exceeds the wear resistance of wear-resistant steel and stainless steel.


2. Excellent wear resistance

Measured by the Institute of Powder Metallurgy, Central South University of Technology, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. According to our customer follow-up surveys over the past ten years, under the same working conditions, the service life of the equipment can be extended by at least ten times.


3. Lightweight

Its density is 3.5g/cm3, only half that of steel, which can greatly reduce the equipment load.


4. Wide range of application

For example, all the mechanical equipments such as coal conveying, conveying system, pulverizing system, ash discharge and dust removal system of thermal power, iron and steel, smelting, machinery, coal, mining, chemical, cement, ports and wharves can be based on Choose different types of products for different needs.


Cutting method of wear-resistant  tiles:

We use high-hardness diamond blades to cut wear-resistant ceramic liners. The cutting machine can be either a large desktop or a hand-held one, as long as it is protected when cutting, so that the skin is not cut by the cut pieces. Then talk about how to cut, this is the point. Many customers encounter difficulties in this place, saying that everything is broken. Today I will give you a trick. You must pay attention to the position of the knife. You may think that any position can be cut. But our technicians told us that when the high-speed rotating blade touches the wear-resistant ceramic plate in the center position

When subjected to shear stress, the porcelain plate will break. Therefore, the knife must be cut from the end, so that the stress can be reduced to a minimum without affecting the cutting of the wear-resistant porcelain plate. The last thing is to pay attention to the cooling of the cutting blade. When cutting this hard material, the temperature of the blade rises quickly, which will cause the strength of the blade to decrease, so pay attention to cooling the blade with water.
