本发明涉及一种变压器铁芯制造硅钢片绝缘涂装方法，其使用了一种涂装设备，该涂装设备包括基座、支撑架、转动装置、下降装置、滚涂装置与涂装仓，通过顺时针转动转动环，转动环转动带动齿轮转动，从而实现两个支撑弧形板展开的每个硅钢片进行内部支撑，通过向右推动推杆，从而对每个硅钢片进行阻隔，开启驱动电机，驱动电机输出端带动中心转轴转动，使滑动杆向下移送时带动匚型架向下移动，实现对匚型架内的硅钢片进行浸涂，匚型架向上移动时由于弹簧的作用力进行上下摆动，从而对硅钢片上多余的绝缘漆进行摆掉，开启电动推杆向前移动，从而对支撑弧形板外侧的多个硅钢片进行表面滚涂，避免硅钢片表面在浸涂绝缘漆时产生凸块。

结合工业化生产的无取向硅钢,进行了RH精炼添加稀土合金实验。结果表明,1.15%(质量分数)Si钢的脱硫反应,主要发生在添加稀土合金之后的前5min。最佳的稀土合金添加量为0.6～0.9kg/t钢。钢液经过稀土处理后,加入的稀土总量越多,稀土氧硫化物夹杂物的尺寸就越大,但热轧带钢再结晶效果会逐渐变差,成品带钢晶粒尺寸先是快速长大,而后逐渐减小。最佳的钢中存留稀土含量与钢的化学成分有关,应严格控制在2.0×10-3%～6.0×10-3%(质量分数)。在此范围内,钢的铁损先是快速降低,而后缓慢升高,钢的磁感应强度则单调降低。 Based on the industrial production of non-oriented electrical steel,rare earth(RE) alloy treatment during the RH refining process was studied.The results showed that the effects of desulfurization and total concentration of RE remained in steel mainly depended on the chemical compositions of different steel grades.For 1.15wt% Si steel grade,the desulfurization reaction mainly focused on the initial 5min after RE alloy added during the RH refining process.The suitable RE alloy addition was 0.6-0....
