A Novel Proposal for Manufacturing Steel: OSRAM's CO$_2$ Steel Making Process
Abstract
In this paper, we propose a concept to utilise Carbon-dioxide for Steel-Making and would like to name it after the first author as OSRAM-CO-SM process. We found in our lab experiments that the carbon content in high-carbon ferro-chrome metallic powders has come down from 7% to 1% when pure CO gas with partial pressure of 1 atmosphere is passed through a horizontal retort furnace maintained at 1100 C for 24 hours. Our results clearly demonstrated that decarburisation can be very effective, when CO is used at temperatures where it is unstable and the Boudouard reaction which is endothermic in nature is more favoured. Based on these findings, we propose the OSRAM-CO-SM process in which CO shall be used as the decarburising agent. CO is to be passed into a specially designed converter provided with heating mechanism to maintain the contents from blast furnace in a molten state for decarburisation of the melt. The out coming hot gases consisting of CO has to be burnt in a combustion chamber with stochiometric proportions of pure O to produce CO at a partial pressure close to 1 atm.The process will be extremely useful as it involves reuse and recycle of CO and in turn would reduce the overall amount of CO discharged into the atmosphere.
