Steel industry
Advanced anti-wear program for the steel industry----Bright arc welding repair continuous casting roll

Provided solution
We have developed a martensitic welded structure with a certain 8-ferrite by developing nitrogen wire.
Alloying conditions of chromium, molybdenum, nickel, and nitrogen are added to achieve maximum corrosion and oxidation resistance - the corrosion loss index exceeds 20.
High temperature wear resistance, microstructure stability and mechanical properties are optimized by microalloying and grain refinement.
Characteristics
New surfacing welding wire with nitrogen and carbon
In order to minimize chromium depletion around the grain boundaries, the carbon content of the solder material must be minimized. Nitride is different from bulk carbides accumulated at grain boundaries, and its precipitates are small and evenly distributed, and do not cause sensitized regions. These precipitates have a tendency to prevent grain growth and hinder the movement of dislocations, thereby improving the high temperature and low temperature strength, completely eliminating or at least inhibiting the formation of carbides, resulting in improved heat fatigue resistance and creep resistance, and improved. toughness.
Simple preheating before welding, no heat treatment after welding
The 414N-0 self-shielded flux-cored wire has a lower martensite transformation temperature range, which helps to reduce the preheating and interlayer temperatures, accelerates the cooling process of the weld overlay, and improves the hardenability (hardening).

Advanced steel industry anti-wear program - bright arc welding repair continuous casting roll

Advantage
The life of the roller after welding can be at least doubled.
Improve roller performance and reduce the cost of downtime or the purchase of new spare parts. The welding process is simple and convenient, reducing smoke and dust and improving the working environment.
The welding deposition rate is high, up to 10 kg per hour.
The welding process is flexible and can be widely applied to open arc welding, submerged arc welding and gas shielded welding.
