EPC general contract of Iran high carbon ferrochrome smelter
High carbon chromium alloy smelting:
In this project, high carbon chromium alloy is smelted by flux
method. The high carbon chromium alloy is obtained by reducing the
chromium oxide of chromium ore with coke and adjusting the melting
point of slag with flux.
Conforming raw materials, higher furnace temperature, good chemical
and physical properties of slag, large reaction area, are the
necessary conditions to ensure the high carbon chromium alloy
smelting furnace condition.
Main equipment selection:
At present, the furnace type of high carbon chromium series gold
ore furnace is mainly semi-closed ore furnace, according to the
characteristics of products and raw materials, some ore furnace
adopts closed structure.
The content and scope of the project consists of the following
workshops or facilities in the plant:
1) Raw material workshop
2) Raw material pre-reduction treatment workshop (ore sintering,
users can choose according to the ore)
3) Mineral furnace workshop 1 workshop (1×16500KVA mineral furnace
is a workshop)
Production utility
1) 33KV general drop and power supply and distribution facilities
2) Water supply and drainage facilities
3) Mineral furnace flue gas purification, dust removal and
ventilation facilities
4) Automatic instrumentation facilities
5) Electrode shell production and machine repair workshop
6) Testing facilities
7) Civil works
8) Fire protection facilities
9) General transport facilities
