Working principles of cooling stave: Through surface cooling, the heat transferred from the blast furnace can be smoothly exported to prevent the high-temperature heat flow from directly reaching the furnace shell, and the cooling stave is installed between the brick lining and the furnace shell to achieve this effect. For modern blast furnaces with full cooling stave structure, staves or water cooling plates are installed on the furnace shell from the furnace bottom to the furnace throat, forming a fully cooled furnace body structure. The heat from the blast furnace is transferred to the environment through the cooling water through the heat exchange with the cooling wall.
TYMC offers several cast iron grades, EN GJL 150-250, EN GJS 450-10, EN GJS 400-18. Each one is suitable for a different part on the blast furnace shelf. With cold bending cooling pipe cast-in the stave body, the stave cooler can face complex working conditions inside the blast furnace.
The useful life of the stave coolers reaches more than 15 years thanks to the care from the TYMC team in the conception and manufacturing of the product. The know-how allowed us to equip more than 300 blast furnaces in the world.

Product Description
The blast furnace stave cooler serves as a critical heat dissipation component installed between the furnace’s brick lining and shell. Its main function is to protect furnace integrity by efficiently removing heat, thereby extending the furnace operational life. This product targets industrial users maintaining or upgrading blast furnace systems requiring reliable cooling solutions to manage high-temperature environments typical in steel production facilities.
Manufactured using cast iron grades such as EN GJL 150-250, EN GJS 450-10, and EN GJS 400-18, the blast furnace cooling stave integrates cold bending cooling pipes cast into the body for enhanced durability under thermal stress. These structural and material choices support a lifespan exceeding 15 years under typical operating conditions and are selected to address varying thermal demands in different furnace areas, including tuyere, belly, bosh, and furnace body.
The blast furnace stave cooler is suitable for both new installations and retrofit projects in steel plants. Its compatibility with full cooling stave furnace structures enables replacement of worn components and reduction of downtime. The product is applied in scenarios requiring thermal management to prevent damage in critical furnace zones, supporting consistent heat transfer and maintenance workflows across heavy-duty metallurgical operations.
