Description

Technical Field

[0001] This utility model relates to a rolling mill fixed guide cylinder, belonging to the technical field of steel ball production equipment. Background Technology

[0002] Steel balls, as the grinding media in ball mills, are widely used in the grinding process of ball mills. Ball mills are the main equipment in mineral processing and are widely used in the grinding processes of mineral processing plants. my country is a major ore-producing country with a large number of ball mills in use, which requires a large quantity of steel balls. Steel balls are consumable parts, and the annual consumption is substantial. Forged steel balls are widely used due to their long service life. Hot-rolled steel balls are also widely used because of their stable internal quality, dense microstructure, fine grains, resistance to deformation, and good wear resistance.

[0003] Conventional hot-rolled steel ball production processes generally adopt the ferrous metallurgical industry standard for forged (rolled) steel balls (YB / T091-2005) to professionally produce hot-rolled grinding steel balls of various specifications, with a diameter range of ￠25~￠125mm. The billets used for rolling grinding steel balls are hot-rolled round steel bars of various chemical compositions, with a diameter equal to the nominal diameter of the steel ball; conventional hot-rolled steel balls mainly... The production process should be as follows: Step 1: After inspection, the round steel bars are cut into steel ball blanks according to the specified length; Step 2: The steel ball billet is heated to a suitable temperature in a continuous heating furnace before rolling; Step 3: After the red-hot steel billet is fed into the hot rolling mill, it passes between two rolls with special spiral grooves. It rotates forward and is continuously rolled into steel balls; Step 4: The rolled red-hot steel balls are immediately sent to a heat treatment device for quenching and tempering heat treatment, so that the steel balls... Achieve high and uniform hardness; Step 5: Products that pass inspection are sent to the finished goods warehouse, packaged, and then shipped to customers.

[0004] Currently, step three typically involves using a feed roller conveyor to feed the red-hot steel billet into a hot rolling mill for rolling. Because round steel bars inevitably have a certain degree of bending, the portion of the bar that does not enter the rolling mill experiences severe shaking, sometimes even... It may be thrown off the roller conveyor, which could easily injure staff standing nearby, posing a serious safety hazard. Utility Model Content

[0010] Optionally, a support bolt is provided on one side of the lower wedge seat. The lower end of the support bolt is connected to the support base by a thread, and the upper end of the support bolt is hinged to the upper wedge seat by a pin.

[0011] Optionally, there are multiple support bolts, which are arranged at intervals.

[0012] Optionally, an adjusting nut is provided at the lower part of the support bolt.

[0013] Optionally, a hinge seat is provided on the other side of the lower wedge seat, and a locking arm is hinged on the hinge seat via a hinge shaft. The upper wedge seat has a slot at the corresponding position of the locking arm, and the locking arm is disposed in the slot.

[0014] Optionally, there are multiple hinge seats, which are arranged at intervals, and each hinge seat is hinged with a locking arm.

[0015] Optionally, a locking wedge groove is provided on the upper part of the locking arm, and a locking wedge block is provided in the locking wedge groove.

[0016] Compared with the prior art, the advantages of this utility model are: 1. This utility model can effectively prevent the problem of violent shaking or even bouncing of the rear section of existing round steel bars due to a certain degree of curvature during rolling. It is reasonably designed and easy to operate, improving the safety of workers. 2. The guide tube of this utility model is clamped and fixed by two wedge-shaped blocks, ensuring a stable and high-quality fixation. 3. The guide tube is easy to fix and disassemble, which is beneficial for subsequent maintenance and replacement. Attached Figure Description
