摘要 浇铸过程无磁钢20Mn23A12V(/%:0.14~0.20C、≤0.50Si、21.5~25.0Mn、1.50~2.50A1、0.04~0.10V)中的Al-[A1]易与保护渣中的SiO2-(SiO2)反应,导致结晶器保护渣变性,要求低碱度、低A12O3的保护渣;并且该钢合金元素含量高,液相线温度低,要求低熔化温度的保护渣。设计了3种低碱度(0.55—0.61)、低熔化温度(904~1015℃)的结晶器保护渣(20.2~24.4CaO、35.3—40.0Si02、2.2~4.1A120,、3.0~5.0B:0,),经25t中间包,200mm×l260mm板坯连铸试验。结果表明,5.0%B:0,碱度0.50~0.60、熔化温度1010℃、粘度0.215Pa·s的无磁钢20Mn23A12V保护渣在0.60~0.65m/min拉速下能较好的满足连铸工艺要求。 The A1 in non-magnetic steel 20Mn23A12V (/% : 0. 14 -0.20C, 〈0.50Si, 21.5 -25.0Mn, 1.50 - 2. 50A1, 0. 04- 0. 10V) - [ All easily reacts with SiO2 in mold powder- ( SiO2 ) led to modification of mold powder and the liquidus temperature of non-magnetic steel is lower because of higher alloy elements content, therefore the mold powder with low basicity, low A1203 content and low melting temperature is required. Three kinds of mold powder (/% : 20. 2 - 24. 4CaO, 35.3 -40. 0SiO2,2. 2 -4. 1A1203 , 3.0 -5. OB203 ) with low basicity (0. 55 -0. 61 ) and low melting tempera- ture (904 - 1 015 ℃ ) have been designed. The test results by 200 mm - 1 260 mm slab casting with 25 t tundish show that the mold powder for non-magnetic steel 20Mn23A12V with 5.0% B203 , basicity 0. 50 -0. 60, melting temperature 1 010 ℃ and viscosity 0. 215 Pa ~ s and in casting speed O. 60 -0. 65 m/min is optimum to satisfy the requirement of casting process.
