Automatic overlay welding for wear-resistant jackets for OG device auxiliary material input.

The wear-resistant jacket using an automatic welding system contributes to maintaining the operational rate of the converter.

The "OG device" is an exhaust gas treatment facility that safely collects high-temperature gas containing high concentrations of carbon monoxide generated from the converter after cooling and dust removal in a non-combustion state. The inner wall is exposed to high temperatures from the exhaust gas of the converter, and as the jacket's inner wall wears and oxidizes in a short period, it may require replacement, resulting in a decrease in equipment operating rate. As a solution to such problems, it is recommended to perform wear-resistant overlay welding using an automatic welding system on the entire inner wall of the jacket. Specifically, through this wear-resistant overlay welding, automatic welding will be carried out on the entire inner wall of a jacket approximately 2.5m long (material: SS400, thickness: 12mm, pipe diameter: 600mm) using a dedicated welding system from WA (WAMS D-2-trak System) and welding materials (307-O, CV-O). The wear-resistant jacket created using this special construction method with an automatic welding system contributes to maintaining the operating rate of the converter. *For more details, please refer to the PDF document or feel free to contact us.
