The temperature control and steam collection component controls the temperature reduction range, preventing water vapor from overflowing while controlling the temperature. The temperature control effect is good, further improving the accuracy of steel rolling. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] A temperature-controlled steam collecting assembly 7 is installed between adjacent mounting plates 3;

[0056] A fixed half pipe 701 is installed between two adjacent mounting plates 3, and a fixed pipe clamp 702 is sleeved on one end of the fixed half pipe 701. A movable half pipe 703 is provided on one side of the fixed half pipe 701.

A movable pipe clamp 704 is sleeved on one end of the movable half pipe 703, and a screw 705 is installed on the top of the movable pipe clamp 704 for rotation. The fixed half pipe 701 and the movable pipe clamp 704 have the same size, and the central axes of the fixed half pipe 701 and the movable pipe clamp 704 coincide with the center of the first wire hole 502, so that the wire passes through the first wire hole 502. The screw 705 is connected to the top of the fixed pipe clamp 702 by threading, and the middle of the movable pipe clamp 704 is fixed and penetrated. A positioning tube 706 is installed, and a temperature probe 707 is installed inside the positioning tube 706. The two ends of the movable half tube 703 are respectively connected to the two ends of the heating tube 708. The two ends of the heating tube 708 are clamped with heat conducting plates 709 inside the movable half tube 703. The two heat conducting plates 709 are respectively connected to the two ends of the heating wire 710. A nozzle 711 is installed through the middle of the fixed half tube 701. The nozzle 711 is connected to the water pump. The temperature probe 707 is connected to the control center. The input end of the heating wire 710 is electrically connected to the output end of the external power supply for easy temperature control. The two ends of the fixed half tube 701 are respectively connected to the two ends of the three-way pipe 712. The middle part of the three-way pipe 712 is connected to the exhaust pipe 713. The exhaust pipe 713 runs through the top surface of the water tank 714. A vacuum pump 715 is installed at one end of the top surface of the water tank 714. The water tank 714 is installed on the top surface of the support plate 716, and the support plate 716 is connected to the side of the finishing mill box 2;

[0057] The high-temperature wire passes through the middle of the hollow cylinder formed by the fixed half-tube 701 and the movable half-tube 703. The vacuum pump 715 reduces the air pressure in the water tank 714. When the temperature probe 707 detects that the wire temperature is too high, the nozzle 711 sprays water to cool it down. At the same time, the water vapor generated enters the water tank 714 through the three-way pipe 712, and the electric heating wire 710 heats the temperature to control the temperature reduction range.

[0058] The working principle and use process of the present invention are as follows: abrasive sand is poured into the grinding box 503, and then the spiral conveying rod 510 is placed in the semicircular tube 507, and the end cover 508 is installed at the top of the semicircular tube 507. The wire passes through the first wire hole 502, the second wire hole 603 and between the two adjacent finishing rollers 4. When the wire is inside the heat insulation frame 602, under the push of the support spring 608, the support roller 617 in the clamping frame 609 squeezes and fixes the wire. The support roller 617 rotates with the movement of the wire, and the rotation of the support roller 617 will rub the top of the graphite rod 615 lifted by the lubricating spring 614, grinding out a small amount of graphite powder for lubrication. The outer side of the wire is not smooth, and the protrusions will push up the support roller 617 at the corresponding position. The support block 611 slides along the guide groove 610, the buffer spring 616 contracts, and the lubrication tube 612 moves with the movement of the support block 611. The connecting plate 618 slides along the guide rod 621, and the induction spring 620 is deformed. The pressure sensor 619 detects the pressure, while the carbon fiber cloth 622 and asbestos cloth 623 play a role of heat insulation protection to prevent the pressure sensor 619 from being damaged by high temperature. The deformation position is known, and multiple parts are tested simultaneously to ensure the detection accuracy. If the deformation is large, the machine is stopped for detection. If the deformation is small, the continuous grinding component 5 can be started through the control center.

[0059] When the continuous grinding component 5 is working, the spiral conveying rod 510 drives the grinding sand to the upper end of the semicircular tube 507, and the grinding sand enters the grinding box 503 from the top of the partition plate 506, moves along the partition plate 506 to the position of the groove on the outer side of the finishing roller 4, and is automatically polished as the finishing roller 4 rotates. The grinding sand continues to slide down along the triangular guide block 505 to the bottom end of the spiral conveying rod 510, and continues to be transported. The above process is repeated, and the broken grinding sand passes through the sand filtering holes 512 of the filter plate 511 and enters the collecting cylinder 514. The baffle 518 and the brush 516 scrape off the grinding sand attached to the groove on the outer side of the finishing roller 4 in turn, and fall into the cleaning box 515. When it is opened, the grinding process does not need to be stopped, which improves the steel rolling efficiency. The grinding can be continuously carried out during the steel rolling process, and the baffle 518 of the removal hole 517 can be used to collect it, so as to keep the outer side of the finishing roller 4 smooth, thereby improving the accuracy of steel rolling.

[0060] The fixed half-tube 701 and the movable half-tube 703 are spliced ​​into a circular tube. The fixed tube clamp 702 and the movable tube clamp 704 are connected by a screw 705 to fix the movable half-tube 703. During the steel rolling process, the high-temperature wire rod passes through the middle of the hollow cylinder formed by the fixed half-tube 701 and the movable half-tube 703. When the temperature needs to be lowered, when the temperature probe 707 detects that the temperature of the wire rod is too high, the nozzle 711 sprays water to cool it down, and the vacuum pump 715 is started to reduce the air pressure in the water tank 714. The generated water vapor enters the water tank 714 through the tee pipe 712, and the electric heating wire 710 heats the heat conducting plate 709 to control the temperature reduction range. This prevents water vapor from overflowing while controlling the temperature, and achieves a good temperature control effect.

[0061] The detection and positioning component 6 is used to detect the accuracy of the fine-rolled wire rod, and then serves as the basis for starting the continuous grinding component 5. The continuous grinding component 5 continues to grind without stopping, thereby improving the efficiency and accuracy of steel rolling. The temperature control and steam collection component 7 controls the temperature reduction range, preventing water vapor from overflowing while controlling the temperature. The temperature control effect is good, further improving the accuracy of steel rolling.

[0062] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
