Why is the temperature of slag lower than 1530?

Why is the temperature of the slag coming out of the blast furnace much lower than 1530°C? Because a blast furnace does not produce steel but pig iron that melts at 1150 – 1200°C max. The exhaust gas is also rather cold because the air is blown in the bottom part of a blast furnace where it meets the coke.
