Rotary Kiln Sponge Iron Processes T D In Indonesia

Introduction :Apr 29, 2016 A rotary kiln is a tool used to reduce low-grade iron ore and produce sponge iron with a high metallization. This process is in accordance with the Indonesian government policies that regulate the minimum value of percentage of sponge iron metallization for export, i.e. 85%. In this research, sponge iron is made of a mixture of Lampung iron ore

OPERATIONAL ASPECTS OF SPONGE IRON. Rotary Kiln Reduction Process at NML The rotary kiln at NML Fig 3 consists of a steel shell of 900 mm diameter and 10700 mm in length The kiln is provided with spring loaded stationary inlet and outlet segments with pro per air tight seals to prevent infiltration of air or gas leakage between the stationary

Gas-Based Process: This process utilizes natural gas as the reducing agent. Natural gas is reformed to enrich with H2 and CO mixture and this enriched and reformed gas mixture is preheated in gas-based process. A vertical retort is used for the reduction of iron ore as against a rotary kiln in coal based sponge iron process.

INTRODUCTION. Rotary kiln (500 t ons) is a long (80 m), and a slightly inclined rotating horizontal s haft in which iron. ore and coal are f ed from one end (feed end), and coal and primary air

Keywords: Sponge Iron, Heat Transfer, Rotary Kiln . 1. Introduction . In Rotary kiln, carbon is charged from either end, in one end in the form of coal particles and in another in form of coal lumps. The coal reacts with air to form carbon monoxide which then reduces iron oxide (ore) to iron. So, in a kiln,
