一．Multi-series and multi-specifications of our products can meet requirements of installation of different blast furnaces.
1. Cooper stave with integral ledge includes 3 patented products, which are cooper stave with ledge on cold face, cooper stave with ledge on hot face and cooper stave with integral various ledges. Ledges on cold or hot face can smooth the connection of the hot faces between cooper stave’s and neighbor cast iron stave’s. This helps to keep reasonable melting furnace shape of blast furnace and prevent gas from over flowing.
2. Multilayer cooper stave applied composite structure of multilayer stave and base-layer stave. Multilayer stave is an ultrathin cooper stave and base-layer stave is a cast iron or steel stave. Independent cooling channels are set in each layer. This cooper stave not only maintain the cooling performance and mechanical strength, but also saves cooper consumption by 60%.
3. Cooper stave with piping reinforce structure is the one with ledges on inlet and outlet pipes of both ends. Inlet and outlet pipes connect with inside wall of the cooling channel entrance by thread. This perfects the force bearing structure to improve the welding joint quality and strength, and largely reduces cooper material.
4. Cooper stave with unilateral 4 cooling channels and double inlet& outlet pipes are suitable for overall repairing on site and can substitute cast iron staves in bosh, belly, middle and low areas of stack of blast furnace without changing position of the opening hole and dimension of original furnace shell.
