Reformer tube for DRI TOPICN13085 Direct reduction iron is the low carbon porous substances formed by fine iron powder or iron oxide in the furnace through low temperature reduction. The content is stable and has fewer impurities which are used as raw materials of steel making for electric arc furnace; it could be the coolant in reformer steelmaking and also be used for powder metallurgy after secondary reduction. Primary Reformer Tube Working temperature: 900-1000 degrees Material: Upper tube: DIN2.4879, lower tube: DIN1.4852 Diameter is 200-300 mm. Process: Centrifugal casting DRI Reformer Tube
