Melting speed control method in electroslag remelting process

The invention relates to the technical field of electroslag metallurgy, in particular to an electroslag remelting process melting speed control method which comprises the following steps: step 1, melting an electrode at a constant melting speed of 10-15kg/min at the initial stage of electroslag remelting; step 2, when the consumable electrode is melted to 20-30% by weight, starting to reduce the melting speed according to a certain slope; 3, after 40-60% by weight of the raw materials are melted, the melting speed is reduced to 8-13 kg/min, and the raw materials are continuously kept at the melting speed until the raw materials enter a feeding period; compared with the melting speed control in the conventional remelting process, the shape of the molten pool is kept unchanged in the whole remelting process, the solidification condition is stable, and a uniform solidification structure can be obtained. 本发明涉及电渣冶金技术领域，具体涉及一种电渣重熔过程熔速控制方法，包括如下步骤：步骤1，电渣重熔初期采用10-15kg/min恒定的熔速熔化电极；步骤2，当自耗电极熔化达到20-30%重量时按一定斜率开始降低熔速；步骤3
