Abstract

Ternium Sidearar plans to increase Blast furnace #2 production level from 5200 to 7200 THM / day, for this it was necessary to improve the cast house design, especially the main runners. Some of the improvements achieved during relining of blast furnace N°2 were the improvement in parameters that define the operating conditions and the cooling system in the runners. The project involved the next different stages: (1) operational design, (2) thermal and structural analysis for different alternatives, (3) refractory linings construction (pre-cast and security lining), (4) metallic structure assembly. Apart from this, the application conditions of working cement were controlled during the first campaigns. First results show there was an improvement in campaign length, and refractory consumption decreased
