Abstract

본원은 연속주조용 용제 및 용접봉용 용제에 CaO, B2O3의 원료로 사용되는 회붕석을 소성처리시에 결정수가 분해되면서 튀는 비산현상이 발생하는 것을 개선하기 위한 것이다.The present application is to improve the splashing occurs as crystal water decomposes during the calcining treatment of gray limestone used as a raw material of CaO, B 2 O 3 in the continuous casting solvent and the welding rod solvent.

본원의 제조법에 의하면, 적정량의 혼합원료를 용기에 장입하여 소성온도 800~ 1100℃의 소성로에서 30~ 90분 정도 유지하여 소성시킨 후, 스테인레스 용기로부터 분리분쇄하여 그 성분조성이 CaO 30~ 50중량%, SiO28~ 35중량%, B2O320~ 50중량%, AL2O30~ 중량%, MgO 0~ 5중량%, 전체 수분 2중량% 미만인 소성된 회봉석이 제조된다.According to the manufacturing method of the present application, an appropriate amount of a mixed raw material is charged into a container, held in a baking furnace at a firing temperature of 800 to 1100 ° C. for about 30 to 90 minutes, and then fired. A calcined apatite is prepared which comprises%, SiO 2 8-35 wt%, B 2 O 3 20-50 wt%, AL 2 O 3 0 wt%, MgO 0-5 wt%, total moisture less than 2 wt%.
