生产导磁率μ_(10)≥1850G/Oe取向硅钢的工艺包括下列步骤:钢水的准备,其成份主要为(按重量计):≤0.07％碳,2.6～4.0％硅,0.03～0.24％锰,硫和硒的含量为0.01～0.09％,铝和硼至少要有一种,其含量分别为0.015～0.04％和≤0.0035％,≤0.02％氮,≤0.5％铜,其余为铁。把这种钢水进行浇注、热轧、退火、用含有(NH_4)2SO_4、Fe(NO_3)_3、Al(NO_3)3、Mg(NO_3)_2和Zn(NO_3)_2冷轧、脱碳这组含氮化合物一种的基体涂料作涂层以及最终织构退火。
The process for producing silicon steel with the magnetic permeability μ_ (10) ≥ 1850G / Oe includes the following steps: Preparation of molten steel, the composition of which is mainly by weight: 0.07% carbon, 2.6-4.0% silicon, 0.03-0.24% manganese, The content of sulfur and selenium is 0.01-0.09%, and the content of aluminum and boron is at least 0.015-0.04% and ≤0.0035%, ≤0.02% nitrogen and ≤0.5% copper, respectively, and the balance is iron. The molten steel was cast, hot rolled and annealed, and was cold-rolled with (NH 4) 2 SO 4, Fe (NO 3) 3, Al (NO 3) 3, Mg (NO 3) 2 and Zn (NO 3) A base compound of a nitrogen compound for coating and final texture annealing.
