Because the utility model can carry out sectional control on the flow rate of the cooling liquid in the transverse direction along a plate belt according to the technical requirements of the plate shape control, the temperature control capability and the plate shape control capability of a rolling mill can be improved, the plate shape precision of the plate belt can be controlled within 101, and the utility model has the advantages of simple structure, low cost and high work efficiency.
Description
Technical field
The utility model relates to the strip-mill strip in a kind of metallurgy industry steel rolling equipment, particularly a kind of rolling mill refrigerating mechanism.
Background technology
The cooling device of the strip-mill strip in the metallurgy industry steel rolling equipment did not generally possess fragmentation feature in the past, do not possess flow regulating function even if possess fragmentation feature yet, each valve control one row's nozzle, open and close simultaneously, can not each section of breaker roll carry out temperature control, promptly can not realize the hot convexity of every section roll is controlled, so can not realize well the plate shape of strip is controlled.The stage cooling device function ratio of high-precision rolling mill is better at present, but price is very expensive, can not be widely used.Chinese patent ZL 95230544.5 disclosed roll cooling devices are just controlled the area of section of cooling manifold, thereby control the coolant rate of each collector, but do not possess real-time regulatory function and segmentation control function.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model to design a kind of simple in structure, control is convenient, the stage cooling device of reasonable price, can control the flow of each nozzle, realize the segmentation cooling of breaker roll, reach plate shape control requirement strip.
To achieve these goals, the technical solution of the utility model is as follows: a kind of rolling mill refrigerating mechanism is made up of main line, branch pipeline, control valve and nozzle, divides at each a control valve and a nozzle are installed on pipeline.
Main line described in the utility model all is machined in spray beam inside with dividing pipeline, the inlet of described main line and cooling system pipeline are by being threaded, exit at minute pipeline is equipped with nozzle by screw thread, on minute pipeline control valve is installed, the two ends of described spray beam link to each other with memorial archway.
Control valve described in the utility model is to control the switching of nozzle and the control valve of flow.
Control valve described in the utility model is controlled by the milling train automatic control system.
The quantity of the length of spray beam described in the utility model and branch pipeline can be determined according to the rolling mill practice of strip.
Compared with prior art, the utlity model has following beneficial effect:
1, because the utility model can laterally carry out segmentation control to the flow of cooling fluid along strip according to the technological requirement of template control, improved milling train temperature controlling ability and template control ability, strip plate shape precision can be controlled in the 10I.
2, because main line of the present utility model all is machined in spray beam inside with dividing pipeline, and control valve is a standard valve, makes the utility model simple in structure, cost is low, about 1,000,000 yuan of every rolling mill escapable cost.
3, because the utility model can adopt the two-stage control model to control, realized high efficiency.
