제강용 전기로의 랜스 이송장치Lance feeder for steelmaking furnace

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도 내지 제5도는, 본 발명의 제강용 전기로이 랜스 이송장치의 설명도로서,1 to 5 are explanatory views of the electric furnace lance transfer device for steelmaking of the present invention,

제1도는, 랜스 이송장치의 주요부의 구성도,1 is a configuration diagram of the main part of the lance transfer device,

제2도는, 랜스 이송장치의 전체 개략도,2 is an overall schematic view of the lance feeder,

제3도는, 위쪽 로울러 지지체가 아래쪽 로울러 지지체로부터 이탈된 상태도.3 is a state in which the upper roller support is separated from the lower roller support.

Claims (1)

위쪽과 아래쪽에 배치되어진 복수개의 로울러에 랜스(3)가 끼워 지지되고, 아래쪽 로울러(5)를 구동시킴으로써 랜스(3)가 이송되며, 위쪽 로울러 지지체(7)와 아래쪽 로울러 지지체(8)를 기울어지도록 움직임으로써 랜스(3)의 자세를 변경시킬 수 있도록 되어 이는 랜스의 이송장치에 있어서, 상기의 위쪽 로울러 지지체(7)는, 천평 지지 구조체(7A)와 보우기 구조체(7B)를 가지며, 상기의 위쪽로울러(4)는 보우기 형식으로써 지지되고, 2쌍의 보우기(23)을 구비한 보우기 구조체(7B)가, 천평 지지 구조체(7A)에 자세를 자유로이 변화시킬 수있도록 늘어뜨려 착설되고, 그 천평 지지 구조체(7A)의 중앙의 위부위에 가압 스프링(27)이 장치되고, 보우기 구조체(7B)가 아래쪽 로울러 지지체(8)을 향하여 힘이 가하여져 있는 것을 특징으로 하는 제강용 전기로의 랜스 이송장치.The lance 3 is fitted to a plurality of rollers arranged above and below, the lance 3 is transferred by driving the lower roller 5, and the upper roller support 7 and the lower roller support 8 are tilted. It is possible to change the posture of the lance 3 by moving it so that the upper roller support 7 has a flat support structure 7A and a bow structure 7B in the transfer device of the lance. The upper roller 4 is supported as a bow type, and the bow structure 7B including the two pairs of bows 23 is laid down so that the posture can be freely changed on the flat support structure 7A. The pressure spring 27 is provided in the upper part of the center of the said flat support structure 7A, and the bow structure 7B is applied to the lower roller support body 8 for steelmaking characterized by the above-mentioned. Lance transfer station in electric furnace . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
