Abstract:
Blast furnace campaign life has a great effect on technical and economical indexes of ironmaking production. Cooling condition and life-span of cooling apparatus have a great influence on campaign life of blast furnace. Owing to constant flux water supply used for blast furnace cooling at present, cooling intensity doesn't meet the demand of heat load in peak value, concurrently, cooling water supply lacks equilibrium and stability, which will cause burnout of cooling apparatus and diminution of blast furnace campaign life. So temperature difference self-power adjusting valve is introduced to make BF cooling apparatus change constant flux water supply mode to constant temperature difference water supply mode in order to satisfy the need of cooling intensity when heat load wis in peak value.Principle, structure ,properties and function of temperature difference self-power adjusting valve are explained. The flux in different temperature is measured.
