Description

Technical Field

[0001] The invention relates to the technical field of titanium steel processing equipment, in particular to a titanium steel vacuum hot rolling composite processing device. Background Art

[0002] The main purpose of introducing V, Nb and Ti into steel is to refine the grains, increase the strength of steel and optimize the performance of steel. However, the difficulty that arises is that the difficulty of continuous casting increases because the brittleness range of the ingot becomes wider. If the process control is slightly improper, a large number of crack defects will occur, especially microcrack defects.

[0003] The crystallizer is a continuous steel casting equipment that receives the molten steel injected from the intermediate tank and solidifies it into a solid billet shell according to the specified cross-sectional shape. It is the most critical component of the continuous casting machine. Its structure, material and performance parameters play a decisive role in the quality of the billet and the production capacity of the casting machine. The thickness and structure of the casting powder layer between the crystallizer wall and the shell of the continuous casting billet decisively determine the height of the heat flux density between the steel and the crystallizer, and also decisively determine the thermal load of the continuous casting billet and the thermal load of the crystallizer material. Therefore, especially through local and temporal changes in the casting powder layer in the casting liquid surface area, strong stresses will appear in the shell of the continuous casting billet. These stresses will cause longitudinal cracks, especially in steel types that are prone to cracks. However, the surface of the crystallizer is also subjected to strong mechanical loads through alternating thermal loading, which will cause the billet shell to detach from the crystallizer wall and be pulled apart and leak steel, thereby causing safety accidents. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a titanium steel vacuum hot rolling composite processing device, which uses the supporting force of the telescopic rod and the elastic force of the return spring to expand the connecting block outward, so that the connecting block drives the extrusion plate to extrude the billet shell through the sleeve, temporarily slowing down the speed of the billet shell moving downward to prevent the billet shell from moving down too quickly, resulting in poor cooling inside, causing cracks on the surface of the billet shell, and causing it to be pulled apart and leak steel.

[0024] Specifically, the lifting assembly 5 includes a connecting plate 510, and the connecting plate 510 is fixedly installed on the outer side of the frame 1, a cylinder 520 is fixedly installed on the top of the connecting plate 510, and a pneumatic telescopic rod 530 is fixedly installed on the top of the cylinder 520, a connecting rod 540 is fixedly installed on the top of the pneumatic telescopic rod 530, and an auxiliary rod 550 is fixedly installed on the top of the connecting rod 540. The melting assembly 6 includes a furnace 610, and the furnace 610 is fixedly installed on one end of the connecting rod 540. A feed port 620 is provided at the top of the furnace 610, a discharge port 630 is provided at the bottom of the furnace 610, and an electric heating wire 640 is sleeved on the outer side of the discharge port 630, a shell 650 is fixedly installed on the outer side of the electric heating wire 640, and a rubber sleeve 660 is fixedly installed on the outer side of the shell 650. The connecting plate 510 is provided with two groups of connecting rods 660 and arranged with the central symmetric plane of the frame 1. The furnace 610 is symmetrically arranged, and is fixedly installed between two groups of connecting rods 540 and the auxiliary rods 550. The electric heating wire 640 has a spiral structure, and the electric heating wire 640 is wrapped around the outside of the discharge port 630. Holes are equidistantly provided inside the rubber sleeve 660, and the shape of the holes is a honeycomb structure. This structure is convenient for adjusting the height of the furnace 610 by arranging the electric heating wire 640 and the two groups of cylinders 520. Since the electric heating wire 640 has a spiral structure, it is convenient to evenly heat the discharge port 630, and the holes equidistantly provided inside the rubber sleeve 660 have a honeycomb structure, thereby improving the thermal insulation effect of the rubber sleeve 660, preventing part of the material inside the furnace 610 from cooling down when falling out through the discharge port 630, causing hollowing of the billet shell cooled by the first crystallizer plate 310 and the second crystallizer plate 320.

[0025] Specifically, the guide block 720 has a "T"-shaped structure, and the first crystallizer plate 310 is inserted into the interior of the shell 710 through the guide block 720. This structure sets the guide block 720. When the specifications of the blank shell need to be adjusted, the electric telescopic rod 2 squeezes the first crystallizer plate 310 to facilitate adjustment of the specifications of the blank shell. At this moment, the first crystallizer plate 310 slides inside the shell 710 through the "T"-shaped structure of the guide block 720, so that the first crystallizer plate 310 can stably slide on the outside of the second crystallizer plate 320.

[0026] Specifically, the second circular gear 850 and the first circular gear 840 are provided in three groups and are equidistantly distributed on the outside of the rotating shaft 820, the rack 870 is provided in three groups and is equidistantly distributed inside the box 810, the three groups of first circular gears 840 and the four groups of racks 870 are meshed with each other, the connecting frame 880 is provided in two groups and is symmetrically arranged with the central symmetry plane of the rack 870, and the two groups of connecting frames 880 have a "triangle" structure in appearance. This structure is provided with the rack 870, so that when one group of the two groups of rotating shafts 820 rotates, one group of the two groups of rotating shafts 820 meshes and rotates by providing the second circular gear 850 and the third circular gear 860, so that the two groups of rotating shafts 820 rotate synchronously, so that the three groups of first circular gears 840 mesh and rotate with the rack 870, and because the connecting frame 880 has a "triangle" structure in appearance, the stability between the connecting block 930 and the rack 870 is improved.

[0027] Specifically, the connecting block 930 has a rectangular structure in shape, a groove matched with the connecting block 930 is opened inside the first crystallizer plate 310, the connecting block 930 is inserted inside the first crystallizer plate 310, the inner diameter of the recessed hole 940 is matched with the outer diameter of the connecting block 930, the sleeve 960 has a hole matched with the insertion rod 950, the connecting block 930 is inserted inside the recessed hole 940 and sleeved on the outside of the insertion rod 950, and the bottom end of the sleeve 960 is an arc-shaped structure. This structure is achieved by setting the sleeve 960. Due to the arc-shaped structure at the bottom of the sleeve 960, it is convenient for the sleeve 960 to be inserted into the recessed hole 940 and sleeved on the outside of the insertion rod 950, so as to facilitate the purpose of stably connecting the connecting block 930 to the extrusion plate 970 through the sleeve 960.

[0028] Working principle: the user connects the device to an external power source and then turns on the switch to start the electric telescopic rod 2. The electric telescopic rod 2 squeezes the first crystallizer plate 310 to adjust the specifications of the billet shell. At this moment, the first crystallizer plate 310 slides inside the shell 710 through the "T"-shaped structure of the guide block 720, so that the first crystallizer plate 310 can stably slide on the outside of the second crystallizer plate 320. The cylinder 520 is started, and the cylinder 520 adjusts the height of the furnace 610 through the pneumatic telescopic rod 530, the connecting rod 540 and the auxiliary rod 550. After the furnace 610 performs a high-temperature melting treatment on the material inside, the discharge port 630 is then opened, and the electric power is turned on. The hot wire 640 is connected to an external power source, and because the electric heating wire 640 has a spiral structure, it is convenient to uniformly heat the discharge port 630, and the holes equidistantly opened inside the rubber sleeve 660 have a honeycomb structure, thereby improving the heat preservation effect of the rubber sleeve 660, preventing part of the material inside the melting furnace 610 from cooling down when falling out through the discharge port 630, and causing hollowing of the blank shell cooled by the first crystallizer plate 310 and the second crystallizer plate 320. By setting the extrusion plate 970, the motor 830 is started, and the rotating output shaft of the motor 830 drives the rotating shaft 820 to rotate, and one of the two sets of rotating shafts 820 is driven by two sets of second circular gears 850. The two sets of third circular gears 860 mesh and rotate, so that the two sets of rotating shafts 820 rotate, so that the two sets of rotating shafts 820 drive the two sets of first circular gears 840 to mesh and rotate with the rack 870. At this moment, the rack 870 and the connecting frame 880 pull the sleeve 960 and the extrusion plate 970 toward the inside of the first crystallizer plate 310 through the connecting block 930 and the plug rod 950, so that the outer side of the extrusion plate 970 is at the same horizontal plane as the inner wall of the first crystallizer plate 310, and the first circulation pump 330 and the second circulation pump 340 are started to make the molten steel inside the first crystallizer plate 310 and the second crystallizer plate 320 circulate therein. After 320 cools the blank shell, when the blank shell cools to a certain degree, the rotation of the motor 830 is stopped. At this moment, the supporting force of the telescopic rod 910 and the elastic force of the return spring 920 are used to expand the connecting block 930 outward, so that the connecting block 930 drives the extrusion plate 970 to extrude the blank shell through the sleeve 960, and temporarily slows down the downward movement of the blank shell to prevent the blank shell from moving down too quickly, resulting in poor cooling inside, cracks on the surface of the blank shell, and being pulled apart and leaking steel. In addition, when the extrusion plate 970 and the blank shell are extruded for a long time, the surface of the extrusion plate 970 is severely worn. At this moment, the extrusion plate 970 is conveniently taken out from the inside of the recessed hole 940 through the sleeve 960 for replacement.
