Classification and selection of cladding wear plate wire
In this article, we will discuss the welding wire used for surface treatment. Surfacing wear plate is made of ordinary steel plate with chromium carbide layer covered on the surface, which makes the plate have higher strength. Therefore, the quality of cladded wear plate is mainly determined by the welding wire and cladding process.
In this article, we will discuss the welding wire used for surface treatment. Surfacing wear plate is made of ordinary steel plate with chromium carbide layer covered on the surface, which makes the plate have higher strength. Therefore, the quality of cladded wear plates is mainly determined by the welding wire and cladding process. Wear-resistant welding wire, there are a lot of detailed classification, can be divided into single-layer wire, double-layer wire and multi-layer wire from the use of the category, can be divided into a variety of repair wire and gas-shielded wire wire wire feeding smooth, stable arc, uniform diameter. Welding wire spatter less, less soot, high deposition efficiency. High-quality welding wire basically every package of welding wire is seamless and complete welding wire welding wire with the above characteristics is high-quality welding wire
1.2 mm, 1.6 mm, 2.4 mm, 2.8 mm and 3.2 mm specifications in the wire according to the thickness of different specifications of the wire has different hardness, and good wire hardness can reach HRC55 or higher, the higher the better. Carbon and chromium content determines the hardness of the welding wire alkaline welding wire, the carbon content of about 3.0-5.0, chromium content of 15-30. the surface of the butt-welding layer should have good impact resistance, not easy to fall off, which is the advantage of a good welding wire overlays. Welding wire can be further subdivided according to different industries. For example, if there is a manufacturer, the welding wire can be divided into concrete categories such as cement vertical grinding overlay welding wire, roll overlay welding wire, extrusion roll overlay welding wire, star wheel repair welding wire and so on. Gas-shielded welding wires can also be categorized into impact resistant wires, high temperature resistant wires, gas-shielded repair wires and welding wires containing various special elements.
In the production of surfacing wear-resistant plate, the welding platform is crucial. Currently advanced welding plate platform are fully automatic multi-head platform. Multi-head platform is more efficient than single-head platform welding. The hardfaced wear-resistant plate is not easy to fall off from the welding layer, and the plate bends more. And the new welding plate platform has a high degree of automation, which can control the start, stop and height of each welding gun, and can realize the function of continuous welding at the break point. Welded bimetallic composite wear-resistant plate should be characterized by uniform surface hardness, smooth surface and fine cracks.
In addition, the surfacing technology can not only produce bimetallic wear-resistant plate, but also use the wear-resistant pipe surfacing equipment to surfacing in steel pipe to produce surfacing wear-resistant plate. The production process uses ordinary straight steel pipes with internal wear-resistant layers, which can realize at least 80 mm wear-resistant pipe surfacing. Production lengths of up to 3000 mm are possible.
It can also be welded directly onto elbows. This process is more effective than rolling tubes with wear-resistant plates, and the parts are more durable
A few things to keep in mind when buying wear-resistant cladding plates
In the eyes of professionals, it is not difficult to choose hardfaced wear-resistant plates, just pay attention to the following issues.
1. Understand the basic situation. The main thing is to understand what styles of hardfaced wear plates are available on the market, the performance price of different styles, etc.. Provide a basis for purchase.
2. Choose a reliable manufacturer. Nowadays, there are many manufacturers that provide customized hardfaced wear plates, and the comprehensive strength of different manufacturers is different, which makes the performance of the products different.
3. Choose a good purchasing channel. There are many kinds of purchasing channels at present, such as contacting manufacturers for customization and purchasing in the wholesale market. Before choosing the procurement channel, we should understand the procurement price of each channel, and try to choose the procurement channel with the same type and the same cladding wear-resistant plate with the lowest quotation.
Of course, there are many other issues to consider when purchasing hardfaced wear plates, such as paying attention to the quality of hardfaced wear plates. If the quality is not good, it will inevitably affect the service life and use effect. Surfacing wear plate is formed by adding special elements, such as silicon and manganese elements, to ordinary steel, which can enhance the wear resistance of the steel plate. Before purchasing, qualified customers can also visit the wear surfacing wear resistant plate manufacturers on the spot to understand their production capacity, scale of operation and industry reputation.
