To improve the service life of hot wind pipes of blast furnace and hot wind stove, The standard for the refractory industry of hot wind pipes must be clear.
Refractory materials for hot wind pipes should be controlled by composition.
The quality of the brick lining is ensured by controlling the creep rate of the heavy brick, the change of the permanent line of heating, and the thermal shock resistance.
Through the control of the thermal conductivity of the lightweight brick, the change of the permanent line of heating, the compressive strength and other indicators to ensure its thermal insulation and safe use performance.
Establish appropriate industry standards for hot wind pipes refractories, is beneficial to improve the service life of hot wind pipes, reduce maintenance costs and improve the technical level of iron making.
