一、概况随着电渣钢生产工艺的发展及微型计算机步入电渣冶炼设备领域,工艺要求采用微型机按照“恒熔池形状”方式控制重熔过程,克服由于目前无法调整重熔功率而造成的“递增功率”重熔过程引起的电渣锭头尾成份不均及性能差异,因此要求电渣炉的电源设备能按冶炼工艺要求动态地调整输入电功率,而目前国内电渣炉普遍采用的单相、无载、有级电动换压变压器不能满足这种要求。为了提高电渣钢产品质量,提高工艺的 I. Overview With the development of the production process of electroslag steel and the micro-computer into the field of electroslag smelting equipment, the process requires the use of a microcomputer to control the remelting process according to the “shape of the permanent bath” to overcome the current difficulty in adjusting the remelting power Resulting in the “incremental power” remelting process caused by the composition of the head and tail slag uneven composition and performance differences, thus requiring the power smelting furnace power equipment smelting process requirements to dynamically adjust the input power, and the current domestic electroslag furnace commonly used The single-phase, no load, a grade electric transformer can not meet this requirement. In order to improve the quality of electroslag steel products, improve the process
