The invention relates to a simple and convenient coil moving method for a hot continuous rolling hot coil box, which comprises the following steps of: lifting a steel coil to a roller surface higher than a second coil supporting roller by utilizing a coil pushing roller and a first coil supporting roller B, and simultaneously reducing the speeds of the first coil supporting roller and the second coil supporting roller until the speeds of the first coil supporting roller and the second coil supporting roller fall behind the speed of a finishing mill to generate a speed difference; the steel coil is dragged to the second coil supporting roller under the speed difference to achieve coil moving. The device has the following beneficial effects of simple mechanical structure and low investment; the maintenance workload is small, and the maintenance cost is low; the failure rate is low and the production efficiency is high in the production process. 本发明涉及一种热连轧热卷箱简便移卷的方法，利用推卷辊和一号托卷辊B辊将钢卷托起至高于二号托卷辊的辊面后，使一号托卷辊和二号托卷辊同时降
