Development of Online Hot Oven Repair Methodology in JSW Non-Recovery
Аннотация
Abstract JSW Steel Limited (JSWSL), Salem Works, is the largest special alloy steel plant in India; the only integrated steel plant in Tamil Nadu, and operates two blast furnaces with a combined production capacity of 1.0 million tons per annum of hot metal to cater the fuel requirement of blast furnaces, has a captive coke oven plant of waste heat recovery type batteries comprising of 120 ovens with capacity of 0.5 million tons per annum of metallurgical coke and generates 34 MW power. The waste recovery Chinese type coke oven batteries with silica brick refractories were commissioned in 2007 and have an operational life of 15–18 years approximately. The healthiness of ovens depends on maintaining temperature and refractory. This case study describes about diagnosis methodology to repair problematic oven with in-house made insulated cage for online repair of damaged silica brick oven in short span without compromising inside wall temperature and workman’s safety. Keywords: Coke making, metallurgical coke, silica bricks, insulated cage Cite this Article Reji Mathai, Theepan TK. Development of Online Hot Oven Repair Methodology in JSW Non-Recovery.
