Pour into a mould crystallizer apron device that liquid covering slag was used

The utility model relates to a pour into a mould crystallizer apron device that liquid covering slag was used, include: apron, two at least whorls of root pipes and blow the argon pipe. Set up the upper end of the apron setting of molten steel plug hole and defeated cinder hole at the crystallizer, the apron is sandwich structure, the apron is close to molten steel one side coating hyperthermia radiation coating. Two at least whorls of root pipe is inlayed respectively in the bottom of molten steel plug hole and defeated cinder hole outer fringe, a plurality of through -holes have been seted up to the bottom of ring canal, blow the top intercommunication of argon pipe and ring canal. This crystallizer apron device can completely cut off the air, prevents molten steel secondary oxidation, has improved the heat -insulating property of crystallizer, improves meniscus molten steel temperature, reduces the trace degree of depth of shaking, avoids generating and solidifies the hook, reduces the pinhole and reduces
