The invention discloses a process for controlling the melting speed of a large slab electric slag furnace. The process includes the steps of melting speed process design, offline stimulation computation, and procedure intervention and regulation. Procedure intervention and regulation is realized through voltage and current regulation. The three stages of the starting melting speed, the keeping melting speed and the feeding melting speed are adopted for melting speed process design, and the starting melting speed is 14-16 kg/min. According to the process, process design of the melting speed iscarried out, and the three stages of the starting melting speed, the keeping melting speed and the feeding melting speed are adopted; an Excel table tool is used for carrying out offline simulation onthe designed melting speeds; and in the production procedure, voltage and current can be manually regulated according to the conditions of the practical melting speed, so that the effect that the deviation of the practical me
