PROCEDURE FOR THE PREPARATION OF AN IRON BASED POWDER.

摘要

THE INVENTION REFERS TO A PROCESS FOR OBTAINING AN IRON BASED POWDER, WITH LOW OXYGEN CONTENT AND LOW CARBON CONTENT. THE PROCESS UNDERSTANDS THE STAGES OF PREPARING A POWDER THAT CONSISTS BASICALLY IN IRON AND OPTIONALLY AT LEAST A SELECTED ALLOY ELEMENT BETWEEN THE GROUP FORMED BY CHROME, MANGANESE, COPPER, NICKEL, VANADIUM, NEOBIO, BORO, SILBIANO, SILBIANOUS, SILENCING THE POWDER IN AN ATMOSPHERE CONTAINING AT LEAST H 2 YH 2 O, MEASURING THE CONCENTRATION OF AT LEAST ONE OF THE CARBON OXIDES (ALTERNATIVE GASES) FORMED DURING THE DECARBURIZATION PROCESS, OR MEASURING THE OXYGEN POTENTIAL AT LEAST 2 SITUATED TO A DISTANCE BETWEEN PRE-ESTABLISHED, IN THE LONGITUDINAL ADDRESS OF THE OVEN, ADJUSTING THE CONTENT OF THE GAS H 2 OR IN THE DECARBURIZATION ATMOSPHERE, WITH HELP OF THE MEASUREMENT. ANOTHER ALTERNATIVE IS CARRIED OUT OF MEASURING CARBON OXIDES IN COMBINATION WITH THE MEASURE OF THE POTENTIAL OF OXYGEN.
