连铸水口堵塞对于连铸生产、铸坯质量以及安全生产具有重要影响。通过在水口内外壁附加 ZrO_2固溶体材料并在其两侧施加电场的方法,研究了电场电流对水口正负极附着层厚度的影响。研究结果表明,随着电场电流的增加,与电源正极相连接的水口试样的附着层厚度逐渐减少,而负极的附着层厚度则显著增加。与未施加电场时的水口相比,当电流为1A 时,正极水口的附着层厚度降低了70%,负极水口的厚度增加了72%;而当电流增加至5A 时,正极的厚度降低了90%,负极的厚度则增加了156%。将水口的内外壁设计成正负极并与电源连接时,可以同时防止连铸水口堵塞和减少水口侵蚀。
Continuous casting nozzle blockage for the continuous casting production, slab quality and safety have a significant impact. The effect of electric field current on the thickness of the positive and negative electrode adhesion layer was studied by adding ZrO_2 solid solution material on the inner and outer walls of the nozzle and applying electric field on both sides. The results show that with the increase of the electric field current, the thickness of the adhesion layer of the nozzle sample connected to the positive electrode of the power supply gradually decreases, while the thickness of the negative adhesion layer increases significantly. When the electric current is 1A, the thickness of the positive electrode nozzle is reduced by 70% and the thickness of the negative electrode nozzle is increased by 72% when the electric current is 1A. When the current is increased to 5A, the thickness of the positive electrode is reduced by 90% %, The negative electrode thickness increased by 156%. When the inner and outer walls of the nozzle are designed as positive and negative electrodes and connected with the power supply, it can prevent the continuous casting nozzle from clogging and reduce the erosion of the nozzle.
