ANNOUNCEMENT

LIBYAN IRON AND STEEL COMPANY (LISCO)
MISURATA, GSPLAJ
4.2 MTPY EXPANSION OF STEEL COMPLEX


 

A. Background

Libyan Iron and Steel Company (LISCO) is the only company in GSPLAJ producing rolled steel products in both long and flat categories. LISCO operates the integrated steel plant, Misurata Steel Complex (MSC), which has been in production since 1989. MSC is based on the Direct Reduction-Electric Arc Furnace (DR-EAF) route and was initially designed for a liquid steel production of about 1.3 million tons per year (mtpy), corresponding to finished steel output of about 1.1 mtpy. Over the past few years, the finished steel capacity of MSC has been gradually raised to about 1.7 mtpy through augmentation of production plant units. The major production facilities presently installed in the steel complex are as follows:

- 2 x 550,000 tpy capacity Midrex DR modules for production of DRI

- 1 x 650,000 tpy capacity Midrex DR module for production of HBI

- Steelmelt Shop No. 1 (SMS-1) for billets/blooms, comprising 3 x 90t, 45/54 MVA EAFs, two (2) 6-strand billet casters and one (1) 4-strand bloom caster

- Steelmelt Shop No. 2 (SMS-2) for slabs, comprising 3 x 90t, 45/54 MVA EAFs, two (2) 1-strand slab casters

- 2 x 200,000 tpy capacity bar and rod mills (BRM)

- 120,000 tpy capacity light & medium section mill (LMSM)

- 400,000 tpy capacity wire rod mill (WRM)

- 580,400 tpy capacity hot strip mill (HSM)

- 140,000 tpy capacity cold rolling mill (CRM) complex

- 80,000 tpy capacity galvanizing line

- 40,000 tpy colour coating line


 B. 4.2 mtpy Expansion

LISCO has now embarked in the expansion programme to increase the plant capacity from 1.7 mtpy to about 4.2 mtpy. The above expansion would be carried out by maximizing the liquid steel production from the existing two (2) Steelmelt Shops, i.e. SMS-1 and SMS-2 by converting all existing six (6) EAFs to UHP (90MVA)/EBT furnaces. Also, corresponding up-stream and down-stream plant units have been finalized/getting finalized to co-relate with the increased liquid steel production. Along with the production plant units, power, services and utility system of the steel complex would be augmented to meet the additional requirements.

C. Offers for Services & Utility System

For augmentation of the existing water system, as well as yard and utility facilities, following two (2) tender documents have been finalized and ready for issuance to bidders:
