Abstract
The utility model, being applied to a hot-strip mill, discloses a mangling roller cooling device, comprising a cooling water tank, a nozzle device, a connecting device and a water inlet device. The function is characterized in that changing the pattern of arranging the cooling water nozzle with a collector traditionally into arranging the nozzle on a tanker, thereby fixing the water pressure. Connected with a stander through a screw thread, an impacting water wave is a fan-shaped flat wave, and each row is distributed in a herringbone. The device is characterized in that the device can raise the roller cooling efficiency effectively, has small investment, simple manufacturing technics, convenient operation, wide range of control, and can reduce the intensity of labour and increase the quality of a band steel surface.
Description
Technical field
The utility model belongs to hot-strip factory milling train cooling device technical field, particularly a kind of cooling device of work roll of hot rolling finisher.
Background technology
The cooling device of the finishing mill working roll of existing hot rolled plate factory is made of welding tip connected body on the collector 3～4 collectors, need operating personnel in the frame of being everlasting, to dredge the nozzle of obstruction, the nozzle of replacing wearing and tearing, labour intensity is big, and working environment harmfulness is big, wastes time and energy.On the other hand, collector directly is weldingly fixed on the milling train flipper guide with reinforcing bar, changes difficulty, and the difficult grasp of collector setting angle, relies on workman's experience often, has directly influenced cooling effectiveness.
Summary of the invention
The purpose of this utility model is, provide a kind of temperature that can make hot-strip factory finishing mill working roll in the operation of rolling, in rolling off time, be reduced to the number of degrees of expectation fast, thereby roller surface material and plate surface quality are further optimized, reduce work roll thermal crown, and make things convenient for the working roll cooling device of regular maintenance.
Technical solution of the present utility model is:
The cooling device of operation roll of mill, comprise four cooling water tanks, connect gusset, limit portion gusset piece and water inlet pipe, four cooling water tanks are divided into entrance side upper water box, entrance side lower header, outlet side upper water box and outlet side lower header, described connection gusset is distributed in the top of cooling water tank, limit portion connecting plate is arranged on the two sides of cooling water tank, and being provided with diameter in the bottom of cooling water tank is D
pMudhole, water inlet pipe is connected with cooling water tank; Be provided with many row's nozzles at cooling water tank, and every row's nozzle is dense in the middle of being, both sides sparse distribution gradually, each nozzle with certain fixed angle on the cooling water tank casing.
Further be, the angle α of described nozzle and cooling water tank casing is 0～30 °, the jet face that every row's nozzle forms and the angle β of working roll roll surface are 10 °～20 °, distance L from the spray site to the roll surface is 130～180mm, distance 1 between per two row's adjacent nozzles is 70～90mm, spacing d in every row's nozzle between per two adjacent nozzles is 45～80mm, and spraying water wave is fan-shaped flat line, and its angle (n) is 60 °.
The connecting plate of cooling water tank top and side directly links to each other with the milling train flipper guide with bolt, is convenient to the water tank dismounting.The mudhole of cooling water tank bottom is used to remove the impurity of long-term alluvial in the water tank.
The cooling device of the operation roll of mill described in the technique scheme, change traditional cooling water collector the mode that the mode of nozzle is an installation nozzle on the water tank is installed, the effect of water tank is the pressure before the balance cooling water nozzle, make water to roll surface hitting power equalization, keep the temperature constant of working roll on body of roll direction effectively, improved cooling effectiveness.
In addition, device manufacturing process described in the utility model is simple, with low cost, can be widely used in all types of large, medium and small steel rolling mills.
