Service environment of stainless steel filter screen

Compared with stainless steel mesh belt, the service life of common mesh belt is very short, because our use environment is very complex, such as high temperature, corrosion and other environments As we all know, stainless steel mesh belt is characterized by high temperature resistance, corrosion resistance and high strength 1 When the mesh belt is used in the case of ultra-high temperature over 400 ℃, the temperature will rise due to the heat of the conveying materials, and the strength of the conveyor belt will gradually decline with the rise of the temperature The use limit of stainless steel mesh belt will depend on the temperature and material temperature produced by the rotating friction between material and mesh belt When the temperature is over 400 ℃, please consult the stainless steel mesh belt manufacturer if it will affect the service life of the stainless steel mesh belt Generally, the stainless steel mesh belt is heat-resistant, so it will not affect the service life of the stainless steel mesh belt at 400 ℃, but the service life of the stainless steel mesh belt manufactured by each manufacturer is different due to different manufacturing processes When using stainless steel mesh belt at high temperature, the following problems shall be considered A) heat generated by friction in the work of mesh belt B) due to different manufacturing processes, the thermal expansion coefficient of stainless steel mesh belt is different When different materials are welded together, there is the possibility of thermal fatigue C) when the ambient temperature exceeds 400 ℃, the intermittent reduction caused by the expansion between parts should also be fully considered D) creep E) the ordinary mesh belt has hot brittleness when working at high temperature, and so does the stainless steel mesh belt F) brittleness of carbon precipitation; g) effect of temperature change on the use of stainless steel mesh belt (cooling and expansion); H) effect of high temperature environment on lubrication, silicon, graphite and molybdenum disulfide lubricating oil have good heat resistance 2 When the mesh belt is exposed to corrosive materials, it will cause adverse consequences First of all, the mesh belt parts will become more and more thin, resulting in accelerated wear The rust on the common mesh belt parts will also affect the flexible rotation of stainless steel mesh belt hinge and roller When stainless steel mesh belt works continuously in acid or alkaline environment, stress corrosion and crystal stress corrosion will appear on parts When using mesh belt in corrosive environment, we must attach great importance to the selection of mesh belt parts materials Whether the mesh belt with martensitic stainless steel series as parts will rust depends on the specific working environment It is very useful to master the anti-corrosion technology and correctly use the mesh belt in corrosive environment 3 Using the mesh belt in the grinding environment Using the mesh belt in the grinding environment will cause serious wear In order to ensure the service life of the mesh belt, attention must be paid when using it: a) the mesh belt can be prevented from being directly exposed to abrasive materials by installing the chain cover B) when the mesh belt is exposed to abrasive materials, it is necessary to select a suitable conveyor type; c) reduce the chain speed as much as possible; d) to reduce the hinge pressure composed of the pin shaft and sleeve of the mesh belt, select a larger mesh belt; E) use grease lubricant.
