Flux Cored Welding Wire and Wear Resistant Chromium Carbide Steel Plate

The surfacing composite wear-resistant plate is based on mild Steel Plate, and a layer of chromium carbide is surfacing on the surface to make the steel plate have higher strength. Therefore, the quality of the surfacing wear-resistant plate is mainly determined by the Welding Wire and the surfacing process. There are many detailed classifications of wear-resistant welding wires. First, it can be divided into single-layer welding wire, double-layer welding wire and multi-layer welding wire. From the use category, it can be divided into various repair welding wires and gas shielded welding wires. High-quality welding wire has smooth wire feeding, stable arc and uniform diameter. The spatter of the welding wire is small, the smoke is small, and the deposition efficiency is high. For high-quality welding wire, each package of welding wire is basically a whole welding wire without seams. The welding wire with the above characteristics is a high-quality welding wire.

Welding wire is classified according to diameter. There are mainly several specifications, 1.2mm, 1.6mm, 2.4mm, 2.8mm and 3.2mm. Different specifications of welding wire have different hardness. The hardness of high-quality welding wire must reach HRC55 or more. The content of carbon and chromium determines the hardness of the welding wire. The carbon content of the basic welding wire is about 3.0-5.0, and the chromium content is between 15-40. After the high-quality welding wire is surfacing, the butt welding layer on the surface should have good impact resistance and not easily fall off. Welding wire can also be subdivided in more detail according to different industries. For example, in some manufacturers, the welding wire can be subdivided into cement vertical grinding surfacing welding wire, roll surfacing welding wire, squeeze roller surfacing welding wire, star wheel for different use machines. Repair welding wire and other specific classifications. The gas shielded welding wire can also be subdivided into impact-resistant welding wire, high-temperature welding wire, gas-shielded repair welding wire, and welding wire containing various special elements.

In the production of surfacing wear plates, the welding plate platform is very important. The current advanced welding plate platforms are all fully automatic multi-head platforms. The multi-head platforms have higher welding efficiency than single-head platforms. The wear-resistant plate of surfacing welding is not easy to fall off, and the flat plate is bent. Moreover, the new welding plate platform has a high level of automation, which can control the start and stop, height of each welding torch, and can realize the function of continuous welding at interruption points. The welded bimetal composite wear-resistant plate should have uniform surface hardness, flat surface and fine cracks.

In addition, the surfacing process can not only produce bimetal wear-resistant plates, but also can use wear-resistant pipe surfacing equipment to perform surfacing in the steel pipe to produce surfacing wear-resistant plates.
