[0021] like Figures 1 to 5 As shown, this utility model discloses a steel ingot refining furnace. During operation, the hydraulic cylinder 5 pulls the pulling seat 7, causing the pulling chain 8 to move on the sprocket 6. This, in turn, pulls the furnace cover 3 off the top of the furnace body 2 via the pulling block 10, thus opening the furnace cover 3. The hydraulic cylinder 5 extends to place the furnace cover 3 on top of the furnace body 2. As the pulling block 10 moves up and down, it drives the limiting slider 19 to slide on the vertical rod 18, providing limiting guidance. After the furnace cover 3 is opened, the dual-output motor 17 drives the screw rod 11 to rotate via the gearbox 16, causing the adjusting block 12 to slide in the adjusting groove, thus moving the mounting seat 1... 3 and column 4 move on top of base 1, and remove furnace cover 3 above furnace body 2 to reduce obstruction of the top of furnace body 2, making it easier to add materials into furnace body 2. Purification liquid is input into purification box 22 through liquid addition pipe 25.
