Referring to fig. 1 and 2, the self-cooling steel forging work roll comprises an outer roll 1 and an inner roll 2, wherein the left end and the right end of the outer roll and the left end of the inner roll are connected through a connecting shaft assembly 3. The connecting shaft assembly comprises a connecting shaft 31 and a flange 32 positioned at one end of the connecting shaft, and the end parts of the outer roller and the inner roller are detachably connected on the flange. The structure is convenient for each part to be disassembled and assembled for maintenance, the parts can be replaced in time after the outer roller or the connecting shaft assembly is worn for a long time, the working roller does not need to be replaced integrally, and the production cost is reduced.
An oil through opening 11 is arranged on the outer roller, and a detachable plug screw 12 is arranged on the oil through opening. After the assembly of the working roller is completed, a proper amount of cooling oil 13 can be injected into the outer roller through the bucket oil port. The screw plug can be opened before the outer roller is replaced, and the cooling oil in the inner part is discharged. A closed cooling cavity 14 is formed between the outer roller and the inner roller, and cooling oil is injected into the cooling cavity and at least overflows the outer wall of the lower end of the inner roller. The circumferential direction of the inner roller is provided with the helical blade 21 along the axial direction, a gap is formed between the outermost end of the helical blade and the inner wall of the outer roller, the gap can be used for cooling oil to flow, the helical blade is prevented from being in direct contact with the inner wall of the outer roller, and the helical blade adopts a conventional structure.
Two steel forging working rolls set up relatively and carry out the slab band rolling, outer roller and interior roller rotate, helical blade synchronous rotation on the interior roller, it flows along circumference and axial in the cooling chamber to drive the coolant oil, make the coolant oil can fully contact helical blade, the inner wall of outer roller and the outer wall of interior roller, further improve heat conduction effect, the coolant oil in the outer roller of slab band upper end still can be close to the slab band, further cool down to the slab band, preferred coolant oil does not cross 1/4 of interior roller, if the coolant oil too can lead to influencing the normal rotation of outer roller, can influence the working effect on the contrary.
