The rotary joint mounting hole 17 communicates with the housing hole 14. The passive end roll neck 1 is provided with a mounting structure. The mounting structure includes a first pin hole 11, a first fastening hole 12, a pressing hole 13, a liquid guide mounting groove 15, and a spring mounting hole 16.
The roll body 2 includes a working layer 21, a transition layer 22, and an inner layer 23. The working layer 21 is made of a high-strength, high-hardness, high-wear-resistance material. In one embodiment, working layer 21 is a hypereutectoid high alloy steel composition. The inner layer 23 is made of a high-toughness and high-strength material. In one embodiment, inner layer 23 is a medium carbon low alloy structural steel composition. The transition layer 22 is 1mm-5mm. The inner layer 23 is provided with a second fastening hole 24, a second pin hole 25 and a plurality of heat dissipation grooves 26.

At this time, the end of the second mounting bracket 54 of the liquid guide 5 is received in the liquid guide mounting groove 15 of the passive end neck 1 and abuts against the hold-down spring 7. At this time, the liquid guide mounting groove 5 is accommodated in the hollow interior of the roll body 2 and the passive end roll neck 1. The swivel joint 91 is attached to the end of the passive end neck 1 and communicates with the water inlet pipe 51 of the liquid guide 5. The water outlet pipe 92 and the water inlet flow rate measurement controller 93 are connected to the rotary joint 91.
When the inner cooling type self-control Wen Gagun is used, the temperature of the roll body 2 is detected by a roll body temperature measuring and controlling instrument.

In order to further save water, a condensing system is connected in series at the position of the cooling liquid outlet, the cooling liquid is cooled and then recycled, and water is fed from the water inlet again. The cooling liquid can be water, or nitrate can be added into the water.
Referring to fig. 7 to 9, a second embodiment of the inner-cooled self-temperature-control roller according to the present invention is shown, in which the structure of the inner-cooled self-temperature-control roller is substantially the same as that of the first embodiment, except that: the working layer 21 of the roll body 2 is provided with grooves 210 so that the roll body 2 is a grooved roll.
