Abstract
The utility model discloses a cold roll condenser tube in continuous rolling is a fixed connection sleeve pipe on the cold roll inner wall including, sheathed tube one end is equipped with the wash port, and another open end has the inlet tube grafting that keeps off the ring with a tip. The joint of the sleeve and the water inlet pipe baffle ring is provided with a sealing ring. The sleeve is welded on the inner wall of the inner cold roll through two fixed supports, the sleeve after water is introduced rotates along with the inner cold roll, and cooling water in the sleeve is discharged from the water discharge hole. The water inlet pipe is only inserted into the sleeve in the inner cold roll for a short time, the sealing ring is tightly pressed at the opening end of the sleeve through the end retaining ring, and water leakage at the joint is prevented, so that the cooling effect is ensured, and the problem of fracture of the cooling water pipe is avoided. The yield can be increased by nearly 20 ten thousand yuan per year by calculating that the inner cooling roller is replaced twice less every year.
Description
Technical field
The utility model belongs to the mechanical equipment of steel rolling field, relates in particular to a kind of cooling water pipe that is used for heat of cooling continuous rolling production line inner-cooled rollgang.
Background technology
Cold roller in the rollgang of hot continuous rolling production line adopts mostly promptly feeds a cooling water pipe in the inside of hollow roll, cools off conveying roller by the circulation of cooling water in the cooling water pipe.But in use there are the following problems for cold roller in this: because interior cold roller rotates, cooling water pipe only is provided with one section short sleeve pipe in the water inlet end, and cooling water pipe is grown (2000mm), and cooling water pipe is at the inner no strong point of interior cold roller, there is cooling water during work in the cooling water pipe, causes the cooling water pipe nose drop.Under action of centrifugal force, cooling water pipe and sleeve pipe contact position constantly rub, and the phenomenon of cooling water pipe fracture therefore frequently occurs, cold roller in having to change, cold roller just needs more than the 4h consuming time in one and change, and directly influences the normal operation of roller-way and the output of band steel.
Summary of the invention
The purpose of this utility model aims to provide a kind of simple possible, and the neither running of cold roller in the influence can be played favorable cooling effect again, produces the interior cold roller cooling water pipe of fracture in effectively avoiding using.
For this reason, the solution taked of the utility model is:
Cold roller cooling water pipe in a kind of tandem rolling is a fixedly connected sleeve pipe on interior cold roller inwall, and an end of sleeve pipe is provided with osculum, and another openend and an end have the water inlet pipe of baffle ring and peg graft.Sleeve pipe and water inlet pipe baffle ring junction are equipped with sealing ring.
Sleeve pipe adopts two place's fixed supports to be connected with interior cold roller inwall; 3 at every place is along sleeve pipe 120 ° of uniform fixed supports radially, and an end is welded on the cover tube wall, in the other end is welded on the inwall of cold roller.
The beneficial effects of the utility model are:
Because sleeve pipe is welded on the interior cold roller inwall by two place's fixed supports, and the sleeve pipe after the water flowing rotates with interior cold roller, and the cooling water in the sleeve pipe can be discharged from the osculum of the other end.Water inlet pipe only has on the interior sleeve pipe of the interior cold roller of very short one section insertion, by end retainer sealing ring is pressed on the ferrule openings end, prevents that the junction from leaking, thereby has guaranteed cooling effect, has avoided the problem of cooling water pipe fracture.Cold roller calculates in twice by changing less every year, but nearly 200,000 yuan of year additional income.
Description of drawings
Fig. 1 is a cold roller cooling water pipe structural profile schematic diagram in the tandem rolling.
Fig. 2 is Figure 1A-A sectional schematic diagram.
Among the figure: water inlet pipe 1, interior cold roller 2, baffle ring 3, sealing ring 4, sleeve pipe 5, fixed support 6.
The specific embodiment
By accompanying drawing as seen, the utility model mainly is made up of water inlet pipe 1, sleeve pipe 5 and fixed support 6.Interior cold roller 2 is the tube roll of a hollow, water inlet pipe 1 external cooling water source, and the internal diameter of sleeve pipe 5 is slightly larger than the external diameter of water inlet pipe 1.In interior cold roller 2, install a cooling water pipe 5, an end opening of sleeve pipe 5, the other end seals, and processes 4 osculums at the end of sealing.According to the length of sleeve pipe 5, determine two place's strong points along sleeve pipe 5 pipe shaft appropriate locations, and on every place strong point, connect 3 fixed supports 6 that the distribution of fixed support 6 is by on 120 ° of circumference that are distributed on sleeve pipe 5 with the pipe shaft vertical welding.And then in the other end of fixed support 6 is welded on the inwall of cold roller.After welding is finished, sealing ring 4 is inserted in the end that water inlet pipe 1 has baffle ring, the water inlet pipe 1 that will be with sealing ring 4 at last inserts sleeve pipe 5 and gets final product.Sleeve pipe and water inlet pipe baffle ring junction are equipped with sealing ring.
Claims (3)
1. the interior cold roller cooling water pipe of tandem rolling is characterized in that, a fixedly connected sleeve pipe on interior cold roller inwall, and an end of sleeve pipe is provided with osculum, and another openend and an end have the water inlet pipe of baffle ring and peg graft.
2. cold roller cooling water pipe in the tandem rolling according to claim 1 is characterized in that sleeve pipe adopts two place's fixed supports to be connected with interior cold roller inwall; 3 at every place is along sleeve pipe 120 ° of uniform fixed supports radially, and an end is welded on the cover tube wall, in the other end is welded on the inwall of cold roller.
3. cold roller cooling water pipe in the tandem rolling according to claim 1 is characterized in that sleeve pipe and water inlet pipe baffle ring junction are equipped with sealing ring.
