본문에 상세히 기재된 바와 같이, 동, 식물유가 혼합된 원유를 가열탱크에 넣고 40。-120℃온도로 가열하여 리놀렌산과 스테아린산, 팔미틴산을 각기 성분 분해하고 수분을 증발시킨 후 침전하여 이물질을 제거하는 제1공정과, 성분 분해된 원유를 농축조에 넣고 교반기회전속도 50/60-100/60RPm으로 회전시키고 0°-25℃를 유지하면서 스테아린산, 필미틴산등이 각기 별도로 응고되어 입자를 이룰 때까지 약 6시간이상 교반농축하는 제2공정과 농축된 원유를 여과기에서 0°-25℃를 유지하며 180-250mesh여과포를 통과시켜 여과하는 제3공정으로 이루어지는 연속 주조용 이형유의 제조방법.As described in detail in the main text, a crude oil mixed with copper and vegetable oil is put in a heating tank and heated to a temperature of 40 ° -120 ° C. to separate linolenic acid, stearic acid and palmitic acid into components, evaporate moisture, and settle to remove foreign substances. Step 1, Put the component-decomposed crude oil into the concentration tank, rotate it at a stirrer speed of 50 / 60-100 / 60RPm and maintain 0 ° -25 ℃ until stearic acid and filtmic acid are separately solidified to form particles. A process for producing a continuous casting mold release oil comprising a second step of stirring and concentrating for more than an hour and a third step of filtering and passing the concentrated crude oil through a 180-250mesh filter cloth while maintaining 0 ° -25 ° C. in a filter.제1항에 있어서, 식물유만을 원유로 하여 제1, 제2, 제3공정을 거쳐 제조되는 연속주조용 이형유의 제조방법.The method for producing a mold release oil for continuous casting according to claim 1, which is prepared through first, second and third processes using only vegetable oil as crude oil.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
