Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metallurgy, in particular to a roller device. Background Art
[0002] The conventional method of casting rolls is to cast one roll at a time. That is, after the molten iron is poured once, when the molten iron in the riser stops rotating, a thin stream of molten iron is added to the riser to the specified height position to prevent the upper roll neck from shrinking.
[0003] However, when using conventional rolling mill production technology to cast and produce large-sized rolling mills, due to the large amount of molten iron during the casting process, the dimensions of the roll surface and roll neck change greatly. After the molten iron rises from the roll surface to the riser, it will generate a large lifting force. Although counterweights are added to the riser, it will still cause the lifting box to leak, resulting in the roll being scrapped and posing a safety hazard.
[0004] Therefore, the utility model provides a roller device. Utility Model Content
[0005] The purpose of the utility model is to propose a rolling roller device, which solves the problem that during the casting process of the existing conventional rolling rollers, due to the molten iron rising from the roller surface to the riser, a large lifting force is generated, resulting in the fire of the lifting box and the scrapping of the rolling rollers. The utility model ensures that during the casting process of the conventional rolling rollers, the lifting box will not fire, thereby avoiding the scrapping of the rolling rollers and improving the safety production coefficient.

[0031] A pouring pipe 3 is provided on the top of the base box 2 and is in communication with the base box 2;
[0032] The pouring port 31 is provided on the pouring tube 3; the molten iron enters from the pouring port 31 and flows into the interior of the base box 2 through the pouring tube 3. As the molten iron is continuously poured, the molten iron inside the base box 2 will continue to increase and the molten iron liquid level will rise accordingly.
[0033] The cold mold cylinder 4 is provided on the base box 2 and is in communication with the base box 2;
[0034] The ejector 5 is provided at the top of the cold mold tube 4 and is in communication with the cold mold tube 4 . When the molten iron enters the ejector 5 from the cold mold tube 4 , a large lifting force is generated on the ejector 5 .
[0035] There are multiple lifting ears 6, some of which are symmetrically arranged on both sides of the cold tube 4, and the remaining lifting ears 6 are symmetrically arranged on both sides of the riser 5; the lifting ears 6 are used to hang on the lifting ears 6 by a crane after the molten iron pouring is completed, and the cold tube 4 can be removed, and it can also be installed through the lifting ears 6 during installation.
[0036] Also includes:
[0037] Two annular sleeves 7 are sleeved on the bottom ears 6 on both sides of the riser 5 and are used to connect with the ears 6 on the riser 5.
[0038] A plurality of connecting blocks 8, with every two connecting blocks 8 being respectively arranged on both sides of one of the annular sleeve plates 7;
[0039] Multiple pull rods 9, one end of each pull rod 9 is connected to one of the connecting blocks 8, and the other end is connected to the outer side of the bottom of the base box 2. The pull rods 9 are fixed to the lifting ears 6 on the ejector 5 through the annular sleeve 7 to limit the upward movement of the ejector 5 on the cold mold cylinder 4.
[0040] A locking block 91 is provided on the end of each pull rod 9 away from the annular sleeve 7, and a plurality of fixing blocks 21 are provided on the bottom of both sides of the base box 2. A locking groove 211 is provided on the fixing block 21, and the locking groove 211 and the locking block 91 are on the same straight line in the vertical direction. The locking groove 211 and the locking block 91 are fixed and locked by a wedge block 22, and the wedge block 22 is used to fix and lock the locking block 91 inside the locking groove 211, thereby fixing the ejector 5 on the cold mold cylinder 4.
[0041] The ejector 5 is fixed to the cold mold tube 4 by an annular sleeve 7, a connecting block 8 and a pull rod 9. This is to ensure that when pouring molten iron, the ejector 5 will not move even if it is subjected to a large lifting force, thereby avoiding the scrapping of the rolling rolls and greatly improving the safety production coefficient.
[0042] Described annular sleeve plate 7 is provided with draw hook 71. When disassembling, can be hung on the draw hook 71 by crane, and whole pull rod 9 and annular sleeve plate 7 are lifted away.
[0043] The cold mold cylinder 4 is connected to the base box 2 through a heightening ring 41 .
[0044] A circular hole 51 is provided on the top of the ejector 5. The circular hole 51 is for observing the pouring of molten iron and preventing the molten iron from overflowing from the ejector 5 due to excessive molten iron.
[0045] The inner diameter of the cold mold tube 4 is greater than the inner diameter of the riser tube 5. Because the sizes of the roll surface and roll neck are different, and the larger size is at the bottom, a larger lifting force will be generated when the molten iron rises.
[0046] Working process: put the locking block 91 on the pull rod 9 into the locking groove 211 in the fixed block 21, and then put the annular sleeve 7 on the pull rod 9 into the ear 6 at the bottom outside the riser, and insert the wedge block 22 into the middle of the fixed block 21 and the locking block 91, so as to fix the bottom of the pull rod 9 on the base box 2; then inject molten iron into the box pouring port 31, and the molten iron flows into the inside of the base box 2 along the pouring pipe 3, and then enters the cold mold tube 4, and enters the riser through the cold mold tube 4. Since the inner diameter value of the cold mold tube 4 is larger than the inner diameter value of the riser 5, when the molten iron enters the riser, it will generate a large lifting force on the riser. Since the pull rod 9 and the annular sleeve 7 lock and fix the riser, the movement of the riser is avoided to prevent the occurrence of fire.
