Submerge-arc-welding-wear-plate

Although the cost of alloy wear plate is increased, the price is about 3-5 times higher than that of ordinary steel sheets and 25% cheaper than high-chromium stainless steel castings. However, considering the service life of the machine, reducing the maintenance cost, the loss of labor and other human and financial losses, etc., due to the rational use of materials, its performance brings double the harvest. The chemical composition of the wear-resistant layer has a carbon content of 4 to 5%, a chromium content of 25 to 30%, and a volume fraction of Cr7C3 carbide in the metallographic structure of 50% or more. For HRC 56 to 62, the hardness of chromium carbide is HV 1400 to 1800. Since the carbide is vertically distributed in the wear direction, the wear resistance is more than doubled even when compared with the cast alloy of the same composition and hardness.

The main characteristics of the alloy wear plate are as follows:

(1) High wear resistance:

It adopts the general alloy system of alloy wear plate, which has excellent anti-wear grain wear performance, and the wear resistance is much higher than heat-treated wear-resistant steel and casting resistance. Grinding cast iron, the wear resistance is also much higher than the spray welding or thermal spraying method.

(2) Impact resistance:

Since the substrate of the wear-resistant composite steel plate adopts a low-carbon steel plate with good plasticity, energy can be absorbed in the process of impact, and thus wear alloy plate has strong impact resistance and crack resistance, and it is applied to working conditions with strong vibration and impact.

(3) Easy to process:

The wear-resistant alloy plate can be made into a standard-sized plate, which is light in weight, convenient in processing and flexible. Due to the use of a soft substrate, it can be formed by cold bending in the inner direction, and can be cut by a heat source such as a plasma arc or a carbon arc. It can be welded and welded to make the field welding work time-saving and convenient.

(4) High-cost performance:

Considering maintenance costs, spare parts costs and downtime losses, the performance price of alloy wear plate manufacturing parts is 2 to 3 times higher than that of ordinary materials. The surfacing is a welding process in which a layer of wear-resistant, corrosion-resistant, heat-resistant metal is applied to the surface or edge of the workpiece. The surfacing has significant economic benefits in improving the service life of parts, rational use of materials, improvement of product performance and cost reduction. Different workpieces and surfacing electrodes should adopt different surfacing processes to achieve satisfactory surfacing results. The most common problem encountered in surfacing is cracking. The main methods to prevent cracking are: preheating before welding, controlling the temperature between layers, and slow cooling after welding. Stress heat treatment after welding. Avoid multi-layer surfacing, using low-hydrogen surfacing electrodes. When necessary, a transition layer (a welding rod with low carbon equivalent and high toughness) is deposited between the surfacing layer and the base metal.
