| description | The steel demand for fine applications have increased considerably in the last years, and the criteria for its
production are even stricter, mainly in relation to the residual elements content and cleanness required. In relation to the
steel cleanness, the main problem faced is the control of the amount and morphology of alumina inclusions, generated in
the steel deoxidation with aluminum. Besides harming the products quality, the presence of non metallic inclusions can
originate nozzle clogging, and consequently interruptions in the process flux. Aiming to improve the steel cleanness and
to minimize nozzle clogging, this study is developed to evaluate the partial substitution of aluminum by calcium carbide in
the steel deoxidation. Along the operational procedures, the calcium carbide was applied to 397 heats, through what the
improvement in steel cleanness is confirmed, with consequent reduction in the nozzle clogging occurrence. |
