Description

Technical Field

[0001] This invention relates to the field of stainless steel production equipment technology, and in particular to a smelting apparatus for producing corrosion-resistant stainless steel for high-performance machine tools. Background Technology

[0002] In the production process of high-performance corrosion-resistant stainless steel for machine tools, the smelting process has a decisive impact on the uniformity, purity, and properties of the stainless steel, while the performance of the smelting equipment directly affects smelting efficiency and product quality. Currently, traditional stainless steel smelting equipment has many shortcomings in practical applications and is difficult to meet the production requirements of high-performance corrosion-resistant stainless steel.

[0003] Existing oxygen blowing mechanisms in smelting plants are mostly fixed structures or can only move in one direction, making it impossible to flexibly adjust the position and depth of the oxygen blowing head according to smelting requirements. When blowing oxygen into the raw materials in the furnace, uneven oxygen blowing often occurs, leading to localized over- or under-oxidation of the raw materials, affecting the compositional stability of stainless steel. While some devices can rotate the oxygen blowing head, they cannot simultaneously accommodate extension and retraction, making it difficult to adapt to the oxygen blowing depth requirements of different smelting stages and limiting the improvement of smelting efficiency.

[0004] Another prominent problem is the unreasonable design of the flue gas exhaust system. The smelting process generates a large amount of flue gas containing harmful substances. If the exhaust is not timely or thorough, it will not only pollute the working environment but may also affect the health of operators. Traditional exhaust systems have fixed positions, making it difficult to precisely align with the furnace opening, resulting in low exhaust efficiency. Furthermore, some flue gas overflows from the furnace opening, making effective collection and treatment impossible.

[0005] To address the aforementioned issues, developing a high-performance smelting device capable of flexible extension and rotation of the oxygen blowing head, efficient and thorough smoke extraction, and stable furnace body adjustment is of great significance for improving the production quality and efficiency of corrosion-resistant stainless steel for high-performance machine tools.

There are two guide hole seats 733, which are fixedly connected to the left and right sides of the connecting seat 7312 respectively. Each of the two guide hole seats 733 has a sliding hole 734 inside its upper side. The fourth motor 7310 is fixedly connected to the center of the upper side of the connecting seat 7312, and the third driving gear 739 is fixedly connected to the output shaft of the fourth motor 7310. The transmission shaft 7311 is movably connected inside the connecting seat 7312, and the center of the transmission shaft 7311...

A transmission gear 736 is fixedly connected to the lower end of each screw 737, and the transmission gear 736 is connected to the corresponding transmission gear 735. Two lifting blocks 732 are externally movably connected to the inside of corresponding sliding holes 734. Threaded holes in the center of each lifting block 732 are connected to the corresponding screws 737. A support block 731 is fixedly connected to the top of each lifting block 732.

[0048] The invention is used in the following manner: The invention has a reasonable and simple structure, low production cost, and convenient installation. In the support adjustment mechanism 7, motor 3 71 is not started, and the smelting furnace 1 is stably placed in the mounting cavity 3 via two rotating shafts 72. The support block 731 of the auxiliary support device 73 is in contact with the bottom of the smelting furnace 1. At this time, motor 4 7310 is in a stopped state, and the lifting block 732 is kept at a fixed height by the limiting of screw 2 737, providing stable support for the smelting furnace 1. Subsequently, the piston rod of cylinder 1 43 of the exhaust mechanism 4 retracts, and the movable tube 41 is housed inside the fixed tube 42. The right end of the movable tube 41 is away from the left side of the smelting furnace 1. Then, cylinder 3 552 of the lifting mechanism 55... The piston rod retracts, placing the internal and external oxygen blowing mechanism 6 at a higher position, away from the opening of the smelting furnace 1. Then, the piston rod of cylinder 53 of the moving mechanism 5 retracts, causing the telescopic arm 51 to move to the left inside the upper side of the mounting base 2. This further moves the internal and external oxygen blowing mechanism 6 away from the smelting furnace 1, facilitating the addition of stainless steel raw materials into the furnace 1. After addition, the piston rod of cylinder 53 of the moving mechanism 5 extends, pushing the telescopic arm 51 to the right via connecting block 54, moving the internal and external oxygen blowing mechanism 6 directly above the smelting furnace 1. Subsequently, the piston rod of cylinder 552 extends, pushing the internal and external oxygen blowing mechanism 6 downwards along the guide hole 551 until the lower side of the movable base 61 approaches the opening of the smelting furnace 1. Simultaneously, the cylinder 43 extends, allowing the right opening of the movable tube 41 to be inserted into the exhaust port 632. Then, the telescopic rotary oxygen blowing mechanism 62 is activated, and the oxygen inlet pipe 621 is connected to the oxygen source. At this time, oxygen enters the annular groove 6283 through the oxygen inlet pipe 621 and the guide hole 6211, and is then sprayed onto the raw material through several blowing holes 6282. At the same time, the motor 624 is activated, and the drive gear 623 drives the driven gear 625 to rotate. The spline shaft 626 rotates synchronously, transmitting torque through the spline sleeve 627, causing the drive gear 6285 to rotate, which in turn drives the driven gear 6284 and the rotating seat 6281 to rotate. The rotating oxygen blowing head 628 can achieve uniform oxygen blowing. When internal oxygen blowing is required, motor 622 first drives screw 629 to rotate, movable arm 6212 moves down along guide hole 6210, spline sleeve 627 moves down along spline shaft 626 with movable arm 6212, and oxygen inlet pipe 621 slides relative to guide hole 6211. Oxygen blowing head 628 moves down to a suitable depth inside smelting furnace 1 with movable arm 6212. Then motor 624 starts again, drive gear 623 drives driven gear 625 to rotate, spline shaft 626 rotates synchronously, and torque is transmitted through spline sleeve 627 to drive drive gear 6285 to rotate, which in turn drives driven gear 6284 and rotating seat 6281 to rotate.Oxygen enters the annular groove 6283 through the oxygen inlet pipe 621 and guide hole 6211, and is then injected into the raw material through several air blowing holes 6282. The rotating oxygen blowing head 628 achieves uniform oxygen blowing, improving smelting efficiency. The flue gas generated during smelting is collected through the transverse groove 631 on the lower side of the movable seat 61, and then discharged to the external collection device through the exhaust hole 632, movable pipe 41 and fixed pipe 42 in sequence. When the smelting is completed and needs to be tilted, the internal and external oxygen blowing mechanisms 6 are first driven to reverse. The material is positioned away from the smelting furnace 1. Then, the motor 7310 of the auxiliary support device 73 starts, driving the driven gear 738 and transmission shaft 7311 to rotate. The two transmission gears 735 on either side drive the transmission gear 736 and screw 737 to rotate respectively. The lifting block 732 moves down along the sliding hole 734, and the support block 731 disengages from the bottom of the smelting furnace 1. Subsequently, the motor 71 drives the rotating shaft 72 to rotate, causing the smelting furnace 1 to tilt, thus allowing the raw materials to be poured out for use.
