Preparation method of special titanium-containing magnesium oxide for oriented silicon steel
The invention relates to the technical field of electrical steel plates, and provides a preparation method of special titanium-containing magnesium oxide for oriented silicon steel, which comprises the following steps: S1, adding magnesium oxide, titanium dioxide and a grinding aid into water, and grinding to obtain ground slurry; s2, after the ground slurry is pressed and filtered, a magnesium-titanium filter cake is obtained; s3, calcining the magnesium-titanium filter cake to obtain titanium-containing magnesium oxide; the magnesium oxide accounts for 90-100 parts by weight, the titanium dioxide accounts for 5-10 parts by weight, and the water accounts for 900-1000 parts by weight; the grinding aid is prepared from the following components in parts by weight: 0.1 to 0.3 part of poloxamer, 0.1 to 0.2 part of sodium p-styrenesulfonate, 0 to 0.2 part of polyethylene glycol monolaurate and 0 to 0.2 part of sodium citrate. According to the technical scheme, the problems that in the prior art, titanium dioxide needs to be physically added when the oriented silicon steel is coated with magnesium oxide, so that the magnetic performance of the oriented silicon steel is poor, and iron loss is increased are solved.
本发明涉及电工钢板技术领域，提出了一种取向硅钢专用含钛氧化镁的制备方法，包括以下步骤：S1、将氧化镁、二氧化钛和助磨剂加入水中，研磨，得到研磨浆液；S2、将研磨浆液压滤后，得到镁钛滤饼；S3、镁钛滤饼经煅烧后，得到含钛氧化镁；氧化镁的重量份数为90~100份，二氧化钛的重量份数为5~10份，水的重量份数为900~1000份；助磨剂包括以下重量份的组分：泊洛沙姆0.1~0.3份、对苯乙烯磺酸钠0.1~0.2份、聚乙二醇单月桂酸酯0~0.2份、柠檬酸钠0~0.2份。通过上述技术方案，解决了现有技术中的取向硅钢涂敷氧化镁时需要物理添加二氧化钛从而导致取向硅钢磁性能较差、铁损增加的问题。
