उत्तर
The temperature in the slag formation zone in the blast furnace is 875-1075 K.
Explanation:
In the blast furnace, the slag formation zone is where impurities like silica (SiO2) react with limestone (CaCO3) to form slag. This reaction happens at a temperature of about 1075-1475 K. The slag helps to remove impurities and protect molten iron from oxidation.
