The invention provides a preparation method of a GH3039 alloy electroslag ingot. The preparation method is characterized by comprising the following steps: 1) controlling the mass percentage of components of a GH3039 alloy; c, Cr, Ni and Mo are added into a crucible, the crucible is put into a vacuum induction furnace till complete melting, vacuum melting is conducted, Nb is added for continuous melting, then Al and Ti are added into the crucible, refining, argon filling and casting are conducted, and a cast ingot is obtained; and (2) the cast ingot is added into a slag pool after barreling treatment, slag is added for electroslag remelting, titanium dioxide is supplemented, argon is filled for protection, the electroslag ingot is obtained, and the prepared GH3039 alloy electroslag ingot is uniform in component, good in surface and easy to thermally process. 本发明提供一种GH3039合金电渣锭的制备方法，其特征在于：包括以下步骤：1）控制GH3039合金的组分质量百分比；将C、Cr、Ni、Mo加入坩埚，并将坩埚放入真空感应炉至全熔，进行真空熔炼，加入Nb继续熔炼、再分别将Al、Ti加入坩埚进行精炼，充氩气，浇铸，得到铸锭；2）将铸锭进行滚磨处理后加入渣池，加
