以一种市售高磁感取向硅钢成品为原料,经一次法试制出了0.10mm规格取向硅钢极薄带,分别通过3种方案进行退火并取样分析,结果表明:1)随炉升温700℃均热退火可获得综合磁性较好的再结晶Goss织构,能满足JEM 1239标准要求;2)低、中温预热+1 150℃均热只能获得位向散漫、低强度的η或近η类等再结晶织构,磁感极低;3)快速加热在1 000℃以下均热能形成具有较高磁感的{110}〈001〉再结晶织构,在1 150℃以上均热,能形成具有较低高频铁损的弱的近{110}〈001〉再结晶织构,有深入研究价值;4)升温速度对再结晶晶粒均匀度有明显影响,快速升温推高初次再结晶温度,并可得到较低的高频铁损;5)对市售取向硅钢成品原料的纯化处理有进一步纯化钢质的作用,没有明显改善磁性能。
Taking a commercially available high magnetic induction oriented silicon steel as raw material, an extremely thin strip of 0.10mm size oriented silicon steel was produced by a single trial. The samples were annealed and sampled by three different schemes. The results showed that: 1) Homogenization annealing can be obtained better magnetic recrystallization Goss texture, to meet the requirements of the JEM 1239 standard; 2) low and medium temperature preheat +150 C soaking can only get diffuse, low intensity η or near η Etc .; 3) Rapidly heating the {110} <001> recrystallized texture with high magnetic induction at a temperature below 1 000 ℃, soaking at a temperature above 1,150 ° C Forming a weak near-{110} <001> recrystallization texture with lower high-frequency iron loss, and has further research value; 4) The heating rate has a significant effect on the evenness of recrystallized grains, rapidly raising the initial recrystallization Temperature, and low-frequency iron loss can be obtained; 5) the orientation of silicon steel products for purification of raw materials to further purify the role of steel, did not significantly improve the magnetic properties.
