Next is the reflection furnace roasting, with fuel combustion and metal smelting each occupying an independent space.
The high-temperature flames produced by fuel combustion pass over firewalls into the smelting chamber, further heating the metal.
Since iron ore is separated from fuel, fewer impurities enter the metal.
However, the disadvantage is that reflection furnace roasting equipment is relatively complex.
If he adopts the reflection furnace roasting method, he will need to dismantle the entire iron-smelting blast furnace.
To reconstruct a double-chamber reflector furnace!
Finally, there's tandem roasting!
After the pig iron comes out of the furnace, it flows directly into the square pond for roasting, eliminating the need for reheating the pig iron.
The advantage of tandem roasting is saving labor time and reducing costs.
Workers don't need to reheat the pig iron, increasing production efficiency while reducing coal required for secondary combustion heating.
However.
