Abstract

본 발명에 의하면 불소함유량이 낮으면서도 저탄소강의 고숙주조를 가능하게 하고 양호한 품질을 갖는 주편을 얻을 수 있는 주형용제에 관한 것이다. 이 주형용제는, 중량 %로 불소(F) 6%이하; LiO2; Al2O38%이하; B2O36$이하; MgO 9%이하; Na27∼12%; 및 염기도(%CaO%SiO2)가 0.8∼1.1 되는 CaO와 SiO2혼합물45∼60%; 로 조성되고, 13000℃에서의 점도가 0.1∼0.5poise이며 응고온도가 920∼970℃인 것이다.The present invention relates to a molding solvent capable of high-temperature casting of low-carbon steels with low fluorine content and obtaining casts having good quality. This molding solvent is 6% or less of fluorine (F) by weight%; LiO 2 ; Al 2 O 3 8% or less; B 2 O 3 6 $ and below; MgO 9% or less; Na 2 7-12%; And 45-60% of a mixture of CaO and SiO 2 having a basicity (% CaO% SiO 2 ) of 0.8-1.1; The viscosity is 1 to 0.5 poise and the solidification temperature is 920 to 970 ° C.
