Quick lime


Right after tapping, with open vault, before scrap loading, the, QUICK LIME system, patent no. 102016000086834, provides for loading lime in EAF, straight on the liquid steel heel for:
  • Immediately obtaining slag with optimal basicity
  • Maximize the yield of lime
  • Reduce lime consumption (5 - 10%)
  • Protect the furnace refractory linings
  • Eliminate all lime handling in the scrap basket

BENEFITS of the QUICK LIME system


SAFETY:
a) Operators’ safety: lime handling is all in closed machinery until charging into EAF
b) Elimination of lime additions in the scrap basket and dust losses (and dedicated plants)
c) Reduction of raw material flows and the consequent spaces / machinery / management needed

ENVIRONMENT:
d) Ecology: reduction of lime dispersions
e) Reduction of waste production
f) Accuracy in dosing: reduction of lime consumption

ECONOMIC SAVINGS
g) On additives: due to reduction of lime needed
h) On lower amounts of fusion energy
i) On conserving lime reactivity: it does not absorb moisture from environment during handling
j) On lime being in liquid slag in the furnace from the beginning of the melting, optimizing its reactions
