전로의 노벽보호를 위한 슬래그의 코팅방법Slag Coating Method for Protection of Furnace Wall

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 취련중 슬래그의 조성변화도.1 is a change in composition of slag during the drilling.

제2도는 종래방법과 본 발명의 조업공정도.2 is a process drawing of the conventional method and the present invention.

제3도는 백운석사용량과 노벽으로부터의 (MgO)용출량의 관계를 나타낸 그래프.3 is a graph showing the relationship between dolomite use and (MgO) leaching amount from the furnace wall.

제4도는 종래 방법과 본 발명의 탈린효과의 비교도.4 is a comparison of the delineation effect of the conventional method and the present invention.

Claims (1)

출강후 용강 1톤당 15-50Kg의 전로슬래그를 노내에 잔류시킨 다음 노체를 정립하여 용강 1톤당 4.4-4.7Kg의 (MgO)에 상당하는 양의 백운석 및 5-20Kg의 생석회를 투입하여 슬래그온도를 강하시킨후 노체를 전,후로 1-6회 경동시켜 슬래그를 전로의 노벽에 코팅시키는 것을 특징으로 하는 전로의 노벽보호를 위한 슬래그의 코팅방법.After the tapping, 15-50Kg converter slag per ton of molten steel is left in the furnace, and the furnace body is established.Then, dolomite and 5-20Kg of quicklime equivalent to 4.4-4.7Kg (MgO) per ton of molten steel are added to the slag temperature. The slag coating method for the furnace wall protection of the converter, characterized in that the slag is coated on the furnace wall of the converter by tilting the furnace body 1-6 times after falling. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
