As preferably, described flow control apparatus for water comprises water ga(u)ge and flow control valve, and when described water ga(u)ge change numerical value exceedes setting value, the uninterrupted of described flow control valve controlled cooling model in-pipe flow remains in setting range.
As preferably, described cooling spray is arranged on the both sides of roll, and the side near roll on described cooling spray is provided with multiple water jet, and described water jet is for being interspersed on cooling spray.
As preferably, described roll comprises roll body and is arranged on the roll shaft at roll body two ends, and described cooling chamber is arranged on roll body inside, is provided with the pod apertures be communicated with cooling chamber in described roll shaft, described roll shaft is provided with swivel joint, and described swivel joint is connected with water inlet pipe and outlet pipe respectively.
As preferably, described roll shaft is provided with bearing, and described roll is rotatably connected in frame by bearing.
As preferably, described roll shaft and swivel joint junction are provided with seal washer.
The utility model has following beneficial effect: the utility model is by arranging cooling device respectively in the inside of roll outer surface and roll, the roller surface major part heat when rolling can be absorbed by external cooling device rapidly, remaining heat is absorbed by interior cooling device, cooling velocity is fast, effective, substantially increases the service life of roll.
