Repair onlin technology
Pressing-in repair method, also called “grouting repair method”, is economical and safe technology for the liner of blast and hot stove without stopping production.
Pressing-in repair method is to drill to shell which decide the depth of drilling according to different positions, purpose technology and requirements.
The technology which uses special pression equipment and pressure condition, pressed refractory to repair area and reach the purpose of repairing liner and gaps.
1. un-influencing production
2. non-change inside structure of the liner
1.Partial overheating and redness of blast furnace, repair of gas leakage.
2.Grouting repair of non-water pressing-in mortar
3.Drilling repair of hard pressing-in material
4.Partial replacement of cooling stick
5.Mending of carbon brick ( technological cooperation with USA )
1.Gap between shell and furnace liner for blast furnace and hot stove
2.Gap between furnace tuyere lining and furnace shell
3.Gap between cooling stave and furnace shell
4.Gap between shell of tap hole and furnace lining
