Abstract

본 발명은 침지노즐을 사용하지 않는 소단면 빌레트(billet)연 주기에서 턴디쉬내용의 용강을 모울드(mold)로 공급하기 전까지 턴디쉬 노즐내에서 용강을 차단하고 있는 분말성상의 턴디쉬 노즐 필러(filler)에 관한 것으로써, 필러의 입도 및 성분을 적절히 선정하므로써, 자연개공율이 우수한 소단면 빌레트용 턴디쉬 노즐 필러를 제공하고자 하는데 그 목적이 있다.The present invention provides a powder-type tundish nozzle filler that blocks molten steel in the tundish nozzle until the molten steel of the tundish content is supplied to the mold in the small section billet lead cycle without using the immersion nozzle ( It is an object of the present invention to provide a tundish nozzle filler for small sectional billet having excellent natural porosity by appropriately selecting the particle size and the composition of the filler.

본 발명은 중량%로 탄소분말:80~90% 및 작성류:10~20%로 조성되고, 그리고 입자가 2㎜이하인 자연 개공율이 우수한 소단면 빌레트용 턴디쉬 노즐 필러를 그 요지로 한다.SUMMARY OF THE INVENTION The present invention is made up of a tungsten nozzle filler for small-section billets having a natural porosity of less than 2 mm, composed of carbon powder: 80-90% and freshwater: 10-20% by weight.
