Description

[0002] Stainless steel products are made through a melting and casting process, where the stainless steel solution is passed through a crystallizer and directly cast into stainless steel products of a fixed shape. This continuous casting method does not require interruption and can continuously process stainless steel products during the casting process, which can stably ensure the processing efficiency of stainless steel products.

[0003] The continuous manufacturing process of stainless steel products is to transport the molten steel that is heated and melted into a stainless steel solution into a tundish, and then transport the stainless steel solution into the crystallizer through the tundish.

[0070] The interior of the hydraulic vibration group 5 is connected to the upper and lower groups of vibration seats through the electromagnetic valve box 54, which can completely change the driving form of the vibration force. While having efficient vibration and free adjustment of the vibration frequency, there is no need to generate any eccentric force that affects the continuous casting crystallizer 3, further improving the quality of the continuous casting crystallizer 3 for processing stainless steel products. The generation of vibration force only requires the drive of the electromagnetic valve box 54, which is simple to maintain and has strong stability in use.

[0071] The use process of the continuous casting molding device for stainless steel products provided by the present invention is as follows:

[0072] During use, the stainless steel liquid that has been melted into a solution is transported to the interior of the solution storage tank 25 , and then the water cooling chamber 34 inside the continuous crystallization tank and the high-pressure pump 511 of the hydraulic vibration group 5 are started.

[0073] After the water cooling chamber 34 is started, the external water source will circulate back and forth through the water cooling chamber 34 to cool the copper crystallizer 31 and cool and shape the stainless steel solution flowing inside it.

[0074] After the high-liquid pump is started, the high-pressure pump 511 absorbs the hydraulic oil inside the hydraulic oil tank 51 through the liquid suction pipe 512 and transports it to the inside of the liquid delivery square tube 513. The oil flows through the liquid delivery square tube 513 to the inner side of the liquid inlet chamber 551 of the valve block 55 in the solenoid valve box 54. The oil flows through the liquid inlet chamber 551 and the liquid delivery chamber 552 into the liquid inlet tank 524. At this time, as the oil inside the hydraulic chamber 522 in the upper vibration seat 52 increases, the pressure inside the hydraulic chamber 522 increases. At this time, the oil drives the hydraulic push rod 523 to slide downward, exerting a downward thrust on the vibration combination seat 32 connected at the upper and lower ends of the copper crystallizer 31.

[0075] When the hydraulic push rod 523 completes the downward movement of the copper crystallizer 31, the electromagnets 56 inside the two sets of solenoid valve boxes 54 are started synchronously, causing the valve block 55 inside the upper solenoid valve box 54 to slide to the right. At this time, the liquid delivery chamber 552 will be closed between the liquid inlet tank 524, and as the valve block 55 moves, a connecting chamber 57 will be formed. At this time, the two ends of the reflux chamber 554 will be connected to the reflux closing port 543 and the liquid meeting port, and the solenoid valve box 54 connected to the lower vibration seat 53 will be in the opposite driving mode to the valve block 55 inside the solenoid valve box 54 of the upper vibration seat 52, and the liquid output from the high-pressure pump 511 will enter the lower vibration seat 53 through the diverter pipe 515.

[0076] The liquid entering the lower vibration seat 53 will drive the hydraulic push rod 523 of the lower vibration seat 53 to move upward, pushing the copper crystallizer 31 to move upward. At the same time, during the upward movement of the copper crystallizer 31, the hydraulic push rod 523 inside the upper vibration seat 52 will be pushed to contract, and the oil inside the hydraulic chamber 522 will be squeezed and transported to the hydraulic oil tank 51, forming an oil circulation. As the high-pressure pump 511 delivers oil, the two sets of solenoid valves are continuously driven to achieve efficient vibration of the copper crystallizer 31, and the vibration frequency of the crystallizer can be freely adjusted according to the solenoid valve.

[0077] During the driving process of the lower vibration seat 53 , since the bottom end of the hydraulic push rod 523 inside the lower vibration seat 53 is connected to the top end of the movable link 71 , the hydraulic push rod 523 drives the movable link 71 to perform reciprocating telescopic motion.

[0078] During the reciprocating telescopic movement of the movable connecting rod 71 , the stainless steel product passing through the middle of the two sets of movable connecting rods 71 ​​will be subjected to the reciprocating rolling pressing of the die-casting roller 72 to achieve thickness control of the stainless steel product.

[0079] When stainless steel products of different thicknesses need to be produced, the adjusting bolt 83 can be rotated synchronously so that the adjusting bolt 83 controls the distance to which the wear-resistant expansion piece 81 extends into the die-casting box 64. By changing the position of the roller 73, the die-casting roller 72 can adjust the size of the stainless steel product according to the distance to which the wear-resistant expansion piece 81 extends into the die-casting box 64.

[0080] During the use of the present invention, the solution storage tank 25 needs to be continuously filled with stainless steel solution, so that the stainless steel solution can enter the solution tank 23 through the feeding nozzle 27. The stainless steel solution entering the solution tank 23 will pass through the shaping extension nozzle 24 to form the stainless steel product blank.

[0081] The formed billet will then enter the copper crystallizer 31 for cooling and shaping. The shaped billet will be affected by the vibration of the continuous casting crystallizer 3 and gradually move downward to avoid sticking to the continuous casting crystallizer 3. At the same time, the casting die-casting part 7 can also pull the stainless steel billet moving downward to realize the transportation of the stainless steel billet.

[0082] It should be noted that the outer side of the continuous casting mold 3 is positioned by a vibration positioning frame 4, and the use of multiple sets of balls can stably ensure its own reciprocating positioning sliding and achieve stable vibration.
