Cooling Staves for Tuyere Area (Pls refer details)

Cooling Staves for Tuyere Area

1. Brief Descriptions

The cooling stave is one of the most important devices/equipment for blast furnace proper, undertaking crucial tasks of protecting furnace shell, cooling and supporting refractory materials, as well as maintaining a reasonable furnace shape. Based on the working principle and failures, Shilin has adopted unique casting technologies to ensure mechanical properties of the parent material, bending forming quality of water cooling pipe, and anti-carburization effect. At the same time, multiple patents and technological achievements have been adopted, significantly enhancing the cooling performance and internal& external qualities. Under normal operations, our products can fully meet the service life of one BF generation.

2. Features of Cooling Staves for Tuyere Area

The structure of this kind of stave and the shapes of cast steel pipe are relatively complex; and mainly used in the tuyere area. The materials can be gray cast iron, ductile iron and others, among them, ductile iron is the main type.

3. Technical Features of Shilin’s Cooling Staves

The cooling staves of Shilin adopts solid wood mold with its own core template resin sand molding process, combined with multiple core technologies such as nano anti-carburizing coating technology for seamless steel pipes, multi-inoculation long-lasting spheroidization technology, and non-welding fixation technology, can ensure

all indicators: chemical compositions, mechanical properties, core pert performances, installation dimensions, anti-carburization effects of steel pipe, air gap between steel pipe and the body, positions of steel pipe, ball passing test, and water pressure test etc to meet or exceed the requirements of national industry standards.
