METHOD FOR PRODUCING AN IMPROVED ELECTRICAL STEEL STRIP |
摘要 |
<p>The invention relates to a method for producing an electric steel strip, in particular an iron oxide-coated steel strip for use as electric sheet steel for the electrical industry; the steel strip is fed in a continuous process to a closed treatment chamber; the electric steel is conveyed into the treatment chamber at a temperature between 450° C. and 550° C. and is acted on there with compressed air and an oxygen concentration of between 0.05% and 0.2% oxygen, measured in the entire furnace chamber atmosphere; and the dew point of water is set to below−10° C. and the furnace chamber atmosphere is a reducing atmosphere; the invention also relates to the electric sheet steel and its use.</p> |
