TISCO's blast furnace hot slag cotton production line has accelerated the industrialization of the whole system. At present, breakthrough results have been achieved in the trial production of high acidity coefficient rock wool products. The related equipment needs to be adapted and optimized. TISCO blast furnace hot slag Cotton making will successfully realize the product upgrade from mineral wool to high-grade rock wool, which not only improves the thermal slag cotton making technology and expands the product categories, but more importantly, it is for the sensible heat recovery and utilization of slag, reducing carbon emissions An effective path has been explored to discharge and realize the operation of the iron and steel associated biological industry.
Blast furnace slag is a by-product of blast furnace ironmaking. In the past, the general practice for comprehensive utilization of blast furnace slag was water quenching to make water slag superfine powder as raw material for cement production, but its huge sensible heat was wasted in vain. In-depth research on comprehensive utilization technology, some foreign companies have begun to try to directly produce mineral wool with blast furnace hot slag combined with formula adjustment, and have achieved success.
The reason why blast furnace slag can be transformed into mineral wool is mainly because blast furnace slag has similar components and can be used as raw material for mineral wool production. The blast furnace slag at high temperature has a lot of sensible heat, if it is fully utilized, the process of heating and melting dry slag in the traditional cotton making process can be omitted, which not only saves energy but also protects the environment.
