    中频炉的感应线圈如何设计？ 感应器是整个炉体的心脏，它不仅直接影响到炉体功率的吸收，其设计的合理性及制造质量也直接影响到炉衬使用寿命。 熔炼炉线圈采用牌号为TU1（纯度为99.9%电解紫铜）、壁厚≥6mm的挤压矩形铜管在专用模具上绕制而成，它不但保证了线圈的刚性而且具有最大的导电截面。以铜螺丝固定在3240绝缘柱上。该铜管具有高导电率和高效率，我公司在制作感应器时，由于炉膛中铁液的高度和直径比较高。采用计算机优化设计分析的基础上确定的，并参考同类设备的使用经验和国外先进炉型，通过多次试验验证，具有结构设计合理、效率高等特点。是设备的自然功率因数得到改善，电效率得到提高。 根据ISO431-1981标准选用线圈材料，具有最小的铜损，最高的电磁转换效率。 感应线圈采用耐高温，耐高压绝缘漆，整体浸涂并经真空烘干，绝缘等级达到H级。感应线圈出厂前经过12kg/cm2水压耐压试验36小时及7000V耐压试验，绝对不会有渗漏水现象出现。 感应线圈上部和下部设有紫铜水冷圈，以保证炉衬受热均匀。而且设有法拉弟短路环，以充分吸收上下端漏磁通，防止炉体发热。感应器接电采用大截面水冷电缆，采用侧引出线形式。线圈压紧装置采用不锈钢拉杆上下拉紧，拆装简单，更换线圈方便。 How to design the induction coil of the induction melting furnace? The inductor is the heart of the entire furnace body. It not only directly affects the power absorption of the furnace body, but the rationality of its design and manufacturing quality also directly affect the service life of the furnace lining. The coil of the smelting furnace is made of TU1 (purity of 99.9% electrolytic copper) and an extruded rectangular copper tube with a wall thickness of ≥6mm, which is wound on a special mold. It not only ensures the rigidity of the coil, but also has the largest conductive cross-section. Fix it on the 3240 insulation column with copper screws. The copper tube has high conductivity and high efficiency. When our company makes the inductor, the height and diameter of the molten iron in the furnace are relatively high. It is determined on the basis of computer optimization design analysis, and with reference to the use experience of similar equipment and foreign advanced furnace models. It has been verified by multiple tests and has the characteristics of reasonable structural design and high efficiency. The natural power factor of the equipment is improved, and the electrical efficiency is improved. The coil material is selected according to the ISO431-1981 standard, which has the smallest copper loss and the highest electromagnetic conversion efficiency. The induction coil adopts high temperature resistant, high pressure resistant insulating paint, the whole is dipped and dried in vacuum, and the insulation level reaches H level. The induction coil has undergone a 12kg/cm2 water pressure withstand test for 36 hours and a 7000V withstand voltage test before leaving the factory, and there will be absolutely no leakage of water. The upper and lower parts of the induction coil are equipped with copper water cooling coils to ensure that the furnace lining is heated evenly. And there is a Faraday short-circuit ring to fully absorb the leakage magnetic flux at the upper and lower ends to prevent the furnace body from heating up. The sensor is connected with a large cross-section water-cooled cable with a side lead wire. The coil pressing device adopts stainless steel pull rod to pull up and down, which is easy to disassemble and replace, and it is convenient to replace the coil.
