Abstract
The utility model provides a cooling element for the roller of rolling mill, comprising the header with spray set on the two sides of the roller of rolling mill, the water-supplying pipeline which bears controlling valve and pressure-flow instrument and joins the header. The invention is characterized in that a plus-pressure pump is set on the water-supplying pipeline and cooling water controlling valves are set on each branch of water-supplying pipelines; the flow-adjusting valve set on each branch of water-supplying pipelines can switch the cooling water; the cooling control to the roller as the requirement according to the roller-outlet direction is realized. The invention effectively enhances the cooling effect of the roller outlet and reduces the very heating point of the roller and has completely solved the de-shaping and crack of roller caused by the poor cooling effect so as to guarantee the rolling piece quality.
Description
Technical field
The utility model relates to a kind of cooling device, the device that especially a kind of rolling mill roll that steel rolling mill is used cools off.
Background technology
In the process that steel plate is rolled, since between rolling deformation heat, working roll and the rolled piece between fricative heat, working roll and the support heat of fricative heat, rolled piece itself etc. all can cause the rising of roller temperature, and the temperature that is prone to body of roll middle part is higher than this uneven phenomenon of temperature of both sides, thereby cause operation of rolling instability, rolled steel plate shape after rolling is poor, even influences normal Rolling Production.Thereby in the operation of rolling, must use the cooling device breaker roll to cool off, but because existing cooling device exists the cooling point few, heat transfer area is little, and heat transfer temperature difference is little, cooling water can not be by deficiencies such as actual needs switchings, especially strengthen when the too high or temperature difference of working roll temperature, and cooling not only easily strengthens the hot convexity of working roll when inhomogeneous, make roller curve be tending towards unstable, directly influence board quality, also can cause roll to crack when serious, finally make rolls damage.Therefore, be necessary prior art is improved.
Summary of the invention
Little for overcoming heat-transfer area and heat transfer temperature difference that existing cooling device exists, cooling water such as can not switch as required at deficiency, and the utility model provides a kind of rolling mill roll cooling device.
The utility model is realized by following technical proposal: a kind of rolling mill roll cooling device, the collector that comprises band shower nozzle on its that is installed in the operation roll of mill both sides, the supply channel which is provided with by-pass valve control and pressure, flow instrument that links to each other with collector, it is characterized in that being provided with on the supply channel force (forcing) pump, and on each the branch's supply channel that links to each other with collector, the cooling water control valve is set.
Described force (forcing) pump links to each other with the cooling device water main, is used for original pressure is brought up to 1.3Mpa by 0.4Mpa, to improve water flow jet pressure and speed.
Described cooling water control valve comprises and being arranged on each the supply water flow control valve be in charge of and the pneumatic operated valve on the same position, pneumatic operated valve leaving and closing as cooling water, flow control valve is used to regulate the flow of cooling water, so that according to the requirement of technology passage only the breaker roll outlet cool off, help improving cooling effect.
The utility model compared with prior art has following advantage and effect: adopt such scheme, can be under the situation of equipment that does not change original cooling system and layout of beam line, effectively improve the cooling capacity of rolling mill roll, especially being arranged on each flow control valve of being in charge of that supplies water can switch cooling water, realized that a roll to the rolled piece Way out cools off control on demand, effectively improve the cooling of breaker roll outlet, reach better cooling effect, make the roll middle part and the temperature difference at two ends narrow down to 11 ℃, and obviously reduce roll working heat convexity, stability in the rolled piece roll gap has been had further to be improved, thereby guaranteed the rolled piece quality, thoroughly solved because of the not good roll deformation that brings of cooling, crack, influence roll service life, increase a series of production problems such as production cost and product quality and be difficult to technical problems such as raising.
