Abstract
The utility model relates to a water leak resistant piece arranged in a roller shaft hole of a fanshaped segment of a continuous casting machine. The water leak resistant piece comprises a hollow piece, and the inner diameter of the hollow piece is the same as the diameter of the shaft hole. Annular grooves are respectively arranged on the outer surfaces of two ends of the hollow piece in the radial direction. Each annular groove is provided with an elastic sealing element. Through arrangement of the elastic sealing elements on the annual grooves of the hollow piece, the water leak resistant piece can achieve good sealing performance and prevent water in a roller shaft from flowing out, and prolongs the service life of a segmental roller.
Description
Technical field
The utility model relates to a kind of preventing water leakage spare that is installed in the shaped sectional roll of continuous casting axis hole.
Background technology
Shaped sectional roll of continuous casting is the roller that contacts at first with high temperature billet steel, can be subject to the Eroded of high temperature billet steel, so, this kind roll shaft to central region be provided with passage for cooling water circulation, be referred to as inner cooling channel; Simultaneously, because of the casting steel billet area larger, in order to improve the Rigidity and strength of fan-shaped section roll, when the wider steel billet of casting needs the long body of roll, usually fan-shaped section roll is divided into 3 joints, and the end at metamerism roller adds support member, and each metamerism roller includes roll body and axially pass the roll shaft of roll body, and the bearing that is limited by bearing block that is arranged on the roll body end of metamerism roller.
In the prior art, the inner cooling channel of each fan-shaped section roll includes the pipe fitting that inserts in the axially extending bore that metamerism roller roll shaft middle part arranges and is used to connect the adjacent adapter sleeve that makes two pipe fittings, adapter sleeve is arranged on the end of metamerism roller, so that cooling water can circulate in pipe fitting, so that fan-shaped section roll is cooled off.Adapter sleeve is mounted in the parts of the end of pipe fitting, and its two ends must be enclosed within respectively on two pipe fittings that connect, and needs by continuously fixing every sealing.Because this kind adapter sleeve is enclosed within on the pipe fitting, the internal diameter of adapter sleeve must when water process adapter sleeve position, can produce certain resistance greater than the internal diameter of pipe fitting, forms eddy current, can hinder flowing of water; In addition; owing to being to adopt plum blossom shaft joint location between two metamerism rollers; in two inconsistent situations of metamerism roller bearing block inner case; perhaps two metamerism rollers can not reach desirable synchronization extent in power transmission; can cause plum blossom shaft joint between the two can be subject to very large shearing force; this shearing force can make water adapter sleeve radial force; cause water adapter sleeve and roller spindle nose connecting hole appearance wearing and tearing in various degree; so that the roller inner cold water leaks; and meeting splash everywhere after the water leakage is easy to make bearing because damaged by water erosion, and damage of bearings can directly affect the normal operation of roller; changing bearing needs to shut down, and then affects the conticaster normal operation.
Summary of the invention
The purpose of this utility model provides that a kind of utilization extends in the metamerism roller and solves the preventing water leakage spare in the shaped sectional roll of continuous casting axis hole of being installed in of the easy leakage problem of water with the mode in footpath with pipe fitting.
The preventing water leakage spare that the utility model proposes is installed in the shaped sectional roll of continuous casting axis hole comprises the hollow that internal diameter is identical with the diameter of axis hole, this hollow two ends outer surface radially be respectively arranged with cannelure, at cannelure elastic sealing element is installed.
Cannelure on the described hollow two ends is respectively arranged with 2-5.
Described hollow length is less than the length of fan-shaped section roll.
The two ends that are installed in the hollow in the interior preventing water leakage spare of shaped sectional roll of continuous casting axis hole that the utility model proposes are inserted into respectively in the axis hole of two adjacent metamerism roller roll shafts, and can realize good sealing at the elastic sealing element that cannelure arranges, the water that can not only hinder in the roll shaft flows out, can effectively protect bearing, prolong the service life of metamerism roller, even and two metamerism roller asynchronous rotations in power transmission, can not cause this preventing water leakage spare to leak yet; Simultaneously, internal diameter and the same footpath of axis hole because of hollow can not hinder flowing of water; In addition, because the length of hollow less than the length of fan-shaped section roll, moves axially Shi Buhui at metamerism roller and produces hollow and spindle nose hard collision, cause this preventing water leakage spare to damage.
Description of drawings:
Accompanying drawing 1 is the outward appearance cut-away section structural representation that is installed in the embodiment of preventing water leakage spare in the shaped sectional roll of continuous casting axis hole that the utility model proposes.
The specific embodiment:
Referring to Fig. 1, this figure provides the surface structure that is installed in the embodiment of preventing water leakage spare in the shaped sectional roll of continuous casting axis hole that the utility model proposes.This preventing water leakage spare comprises hollow 1, this hollow 1 two ends outer surface radially be respectively arranged with cannelure 11, cannelure 11 is provided with two, and on each cannelure 11 elastic sealing element is installed all.Because the fan-shaped section roll water-cooled is to realize water circulation by axis hole, this preventing water leakage spare is be used to the parts that connect adjacent two axis holes, so, hollow 1 in the preventing water leakage spare is inserted in adjacent two axis holes, and the internal diameter of hollow 1 is identical with the diameter of fan-shaped section roll axis hole, can not hinder flowing of water, simultaneously, the length of this hollow 1 is less than the length of fan-shaped section roll.
Claims (2)
1. be installed in the preventing water leakage spare in the shaped sectional roll of continuous casting axis hole, it is characterized in that: this preventing water leakage spare comprises the hollow that internal diameter is identical with the diameter of axis hole, this hollow two ends outer surface radially be respectively arranged with cannelure, at cannelure elastic sealing element is installed.
2. preventing water leakage spare according to claim 1 is characterized in that: the cannelure on the described hollow two ends is respectively arranged with 2-5.
3, preventing water leakage spare according to claim 1 is characterized in that: the length of described hollow is less than the length of fan-shaped section roll.
