Annual Output 500,000-ton Continuous Charging EAF Steelmaking
Product Description
In this scheme, equipped with one set of 50-ton continuous charging
arc furnace, one set of 50-ton ladle refining furnace (optional),
one set of supporting dust removal system (optional), one set of
cooling water treatment system, etc.
It adopts continuous charging electric arc furnace smelting
process, continuous EAF conveys steel scrap and auxiliary raw
materials to the furnace through special conveying equipment,
prheating of the charges at the same time of smelting, its smoke
and dust emissions and noise are small, which can improve the
environment.
Compared with traditional technology or other technologies, EAF has
high productivity, smelting cycle is less than 40min, it is easy to
match with the continuous casting machine, and the power cost is
the lowest.
