In coal power generation, a process is that the coal material is pulverized by a ball mill and then flows into the blanking tank. The coal powder fan works to form a negative pressure, and is pumped into the dust separator to separate the gas powder. The separated coal powder falls into the lifting by its own weight. The device is sent to the boiler for combustion. However, it is not possible to operate the system in a completely ideal state, that is to say that the gas powder in the dust separator cannot be completely separated.
In this way, the gas sucked by the pulverized coal blower will have a certain amount of dust particles, and these dust particles will inevitably cause wear on the pulverized coal blower, mainly on the two parts of the impeller and the casing, and the severity of the wear is caused by The amount of dust varies.
The Faudi anti-wear plate is made by a special hard surface surfacing process. The substrate of the material is a low carbon alloy steel plate. The material plate can be cold rolled or hot rolled, and can be welded and screwed on the back of the plate. Or use other welding structures to fix.
In addition, symmetrical welding and step-down welding should be used for welding to disperse and reduce stress as much as possible to prevent deformation or residual stress of parts. Products with complex welds or for rotating and alternating stress conditions should be treated with stress relief.
