Furnace Startup

Reheating furnace #1 for 1,780mm hot strip mill of Fujian Fuxin Special Steel Co., Ltd. (Formosa Plastics Group) successfully started up on August 7, 2013 after 10 months installation. 

Fujian Fuxin Special Steel Co., Ltd., located in Zhangzhou, Fujian province, China, is a plant to produce #400 and #300 series of high-purity hot-rolled stainless steel sheet and coils using the state-of-the-art technology and equipment.
 
Chongqing CISDI Industrial Furnace Co., Ltd. supplies two reheating furnaces (with max. capacity of 262t/h, for #400 series of stainless steel) for the 1,780mm hot stainless steel strip mill (with capacity of 2.5mt/a). The reheating furnaces are designed with charging/discharging roller table centerline distance of 56m, to reheat typical slabs sized at 200mmx1,250mmx10,800mm.
 
The reheating furnaces burn natural gas, and are provided with low-NOx burners. The combustion system is implemented with control strategy using both impulse combustion and conventional proportional combustion, and is controlled by CISDI L2 mathematic model to allow optimal combustion and accurate control of combustion temperature to improve the slab heating temperature homogeneity while reduce energy consumption and ignition loss, contributing to higher operation flexibility and higher automation level.
 
Cold air is heated up to over 500°C after passing through the efficiency heat exchanger inside the flue, contributing to minimum hot loss. The reheating furnace skids are cooled by evaporative cooling system, which can extend the skid service life while reduce the operation cost.
 
The project team has implemented strict safety management, quality control and installation supervision on site to ensure successful start up of reheating furnace #1.
