REFRACTORY WALL, METALLURGICAL TANK CONTAINING SUCH A REFRACTORY WALL, AND METHOD FOR CONTINUOUS PRODUCTION OF PIG IRON WITH EMPLOYMENT OF SUCH REFRACTORY WALL

摘要

refractory wall for metallurgical tank. SUBSTANCE: the wall has a steel casing, water-cooled bars passing towards the inner side, refractory lining positioned on the bars, and a water-cooled wall located between the steel casing and water-cooled bars. The bars and the water-cooled wall are made of copper. The bars are movable in the vertical direction in the built-up structure of the wall. The upper and lower sections of the bars are inclined upwards and downwards respectively in the direction of the inner side. The bars are spaced in the wall height. The water-cooled copper wall consists of panels. The lining may consists of blocks of graphite, semigraphite or refractory brick. The wall is inclined relative to the vertical with expansion of the metallurgical tank upwards. EFFECT: prolonged service life. 21 cl, 5 dwg
