Description

technical field [0001] The invention relates to a surfacing welding electrode, in particular to a high-temperature-resistant, corrosion-resistant and wear-resistant surfacing welding electrode. Background technique [0002] In industrial production, about 80% of material failure is caused by wear. Some of these workpieces are in service at high temperatures, such as slag removal rollers in the metallurgical industry, distribution chutes in blast furnaces, blast furnace covers, coke pusher slide rails, sieves and other workpieces that work at high temperatures, and their service conditions are harsh. , severe wear and tear, need frequent maintenance, the cost is very high. At present, there are many kinds of surfacing materials suitable for high-temperature wear-resistant working conditions, mainly divided into iron-based high-temperature wear-resistant surfacing materials, cobalt-based high-temperature wear-resistant surfacing materials and nickel-based high-temperature we...

AI Technical Summary

Problems solved by technology

Although cobalt-based alloys and nickel-based alloys have outstanding advantages in terms of corrosion resistance, wear resistance and thermal stability, from an economic point of view, because cobalt is a rare metal, the price is very expensive, and the cost of nickel-based alloys is also very high. , so it is not suitable for wide application

A series of iron-based high-temperature wear-resistant surfacing materials have also been researched in China, but the results are not ideal when the workpieces produced or repaired work under high temperature (>600°C) conditions for a long time
