摘要
通过MgO质坩埚的30kg感应炉，研究了AlMg、SiCaBaMg、SiCaBaAlMg等镁合金（含8％～15％Mg）脱氧剂对0．05％．0．07％C钢的脱氧行为。试验结果表明，用8％～10％Mg的AlMg合金脱氧时，钢中氧含量降低到33．77×10^-6，用15％Mg的SiCaBaAIMg包芯线脱氧，钢中氧含量降低到38．62×10^-6。镁合金在脱氧的同时具看较强的脱硫作用，当钢中起始硫含量为0．063％时，AlMg合金的脱硫率为46．03％，SiCaBaAlMg包芯线的脱硫率为49．21％。
The deoxidization behavior of magnesium alloy （8% ～ 15% Mg） deoxidizer- AlMg, SiCaBaMg, Si- CaBaAlMg to 0. 05% ～ 0. 07% C steel has been studied by a 30 kg induction furnace with MgO crucible. Test results showed that with deoxidation using AlMg alloy contained 8% ～ 10% Mg the oxygen content in steel decreased to 33. 77 × 10^-6, with deoxidation using SiCaBaAlMg alloy contained 15% Mg the oxygen content in steel decreased to 38.62 × 10^-6, while magnesium alloy had strong desulphurization effect during deoxidized period, with initial sulphur content 0. 063% in steel the desulphurization rote by AlMg alloy was 46. 03% and that by SiCaBaAlMg core wire was 49.21%.
