How to Grind Chromium Carbide Plate?
Chromium Carbide plate is composed of two parts: mild steel plate and alloy wear-resistant layer. The wear-resistant layer generally accounts for 1/3-1/2 of the total thickness, and the substrate provides the strength, toughness and plasticity to resist external forces during operation. The wear layer provides the wear resistance to meet the requirements of the specified working conditions.
When the construction of overlay wear plates is used, it is always necessary to grind the high strength overlay wear plates. The main purpose is to maintain the aesthetics of the surfaced wear plate and to ensure the safety of the construction. The grinding method for the surfacing wear plate has three methods: wet grinding, mechanical grinding and dry grinding.
Wet sanding
Use water sandpaper dipped in water or soapy water to sand the high strength surfacing wear plate. Water grinding can reduce the abrasion marks, improve the smoothness of the coating, and save sandpaper and effort. But after the water grinding should pay attention to when spraying the next layer of paint, one is to wait for the water grinding layer completely dry before the next layer of paint, otherwise the paint layer is easy to flood white. In addition, water-absorbent substrates are also not suitable for water-grinding.
Mechanical grinding
High strength surfacing wear plate large area construction, in order to improve efficiency, can use mechanical grinding methods. Such as electric sanding machine, there are disc type and vibration type.
Dry sanding
Sandpaper is used for sanding, which is suitable for hard and brittle paint. The disadvantage of this kind of sanding for high strength surfacing wear plate is that the operation process will produce a lot of iron chips, affecting environmental hygiene.
The above is how to polish the overlay wear-resistant plate, and hope it will be helpful to you. The rapid occupation of the market of surfacing wear-resistant steel plate, in addition to high quality and good performance, also lies in its performance-price ratio higher than other wear-resistant and corrosion-resistant pipes. In the same specification and unit length of the surfacing wear plate, the weight of the surfacing wear plate is only about one-half of the wear-resistant alloy cast steel plate, and its project cost per meter is reduced by 20%-30%; only one-third of the weight of the cast stone pipe, and the project cost per meter is reduced by 5%-10%; the price of the surfacing wear plate used in corrosive or high temperature occasions is only a fraction of that of the stainless steel plate and nickel-titanium plate.
