How to Use
1), For 1-5 T furnace:
- while a small amount molten iron in the furnace,
- or with some molten iron remained, add the carbon additive one-time,
- then add the other material.
which can make carbon additive fully absorbed.
2), For greater than 5 T furnace:
- mix proper carbon additive with charging material as suggested first,
- and then along with the increase of charging material gradually,
- that is, before the molten metal rising up to about 2/3 height of furnace,
- all carbon additive shall be added.
It guarantees sufficient melting & absorbing time before molten metal out, and improves the absorption of carbon.
