摘要： 본 발명은 아연도금강판 생산공정에서 강판 모서리를 가열하는 슬릿형 순 산소 버너에 관한 것이다.
본 발명은 상하로 배치된 다수의 연료 분사 구를 전면에 형성하고, 상기 연료 분사 구에 기체 연료를 공급하는 연료 분사 통을 갖는 연료 분사 부; 상기 연료 분사 구의 양측에 나란하게 상하로 배치된 다수의 산소 분사 구를 전면에 형성하고, 상기 산소 분사 구에 순 산소를 공급하는 산소 분사 통을 상기 연료 분사 통의 외측에 갖는 산소 분사 부; 및 상기 연료 분사 구에 인접하여 배치되어 화염을 착화시키는 점화기;를 포함하여 고온의 청염(blue flame)을 슬릿 형으로 분사시키는 아연도금강판의 모서리 가열을 위한 슬릿형 순 산소 버너를 제공한다.
본 발명에 의하면 순 산소를 산화제로 이용하기 때문에 화염이 고온화되어 강판 모서리의 보다 빠른 가열이 가능하다. 뿐만 아니라 버너가 슬릿형으로 이루어지기 때문에 좁고 상하 방향으로 긴 타원형의 화염을 얻을 수 있음으로써 강판 모서리만을 가열하기에 적합하고, 강판에 화염 불완전 연소에 의한 미연소 성분이 부착되는 것을 방지할 수 있어서 고품질의 아연도금 강판을 얻을 수 있다.
