Description

Technical Field

[0001] The utility model relates to the field of stainless steel processing equipment, in particular to a high-efficiency energy-saving annealing furnace for stainless steel pipes. Background Art

[0002] According to the definition in GB / T20878-2007, stainless steel is steel with stainlessness and corrosion resistance as its main characteristics, and a chromium content of at least 10.5% and a carbon content of no more than 1.2%. Stainless steel is the abbreviation of stainless acid-resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has stainless properties is called stainless steel.

[0003] During processing, stainless steel needs to be annealed in an annealing furnace. After annealing, the stainless steel tube needs to be cooled and then taken out of the annealing furnace. In this way, the heat in the annealing furnace cannot be preserved. The subsequent material needs to be reheated to the appropriate temperature, which causes a large amount of heat waste and increases energy consumption. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

The screw 6 movably passes through the extension plate 4, and the top of the extension plate 4 has a mechanism for driving the screw 6 to move up and down. The power mechanism fixes the stainless steel tube to be annealed on the rail car 9 when in use, and then moves the rail car 9 along the track 7 to the inside of the annealing furnace main body 1, and moves to the side of the first baffle 8, away from the position of the cover plate 2, and then performs annealing. When cooling treatment is required, the rail car 9 is moved to the side of the first baffle 8, close to the position of the cover plate 2, and then drives the second baffle 5 to move downward until the first baffle 8 and the second baffle 5 are closed, and then the stainless steel tube on the rail car 9 is cooled and pushed out after completion. At this time, the first baffle 8 and the second baffle 5 are away from the cover plate 2. The side is in a heat-insulating state until the next batch of stainless steel tubes enters. At this time, the first baffle 8 and the second baffle 5 are separated, so that the heat is filled in the inside of the annealing furnace main body 1, thereby facilitating heat preservation and energy saving.

[0019] The power mechanism includes a motor 10, a rotating shaft 12, a first transmission belt 11 and a second transmission belt 13.

When cooling treatment is required, the rail car 9 is moved to the side of the first baffle 8, close to the cover plate 2 position, and then the second baffle 5 is driven to move downward until the first baffle 8 and the second baffle 5 are closed, and then the stainless steel tube on the rail car 9 is cooled and pushed out after completion. At this time, the first baffle 8 and the second baffle 5 are away from the cover plate 2 side in an insulation state until the next batch of stainless steel tubes enter. At this time, the first baffle 8 and the second baffle 5 are separated, so that the heat is filled in the inside of the annealing furnace main body 1, thereby facilitating heat preservation and energy saving.
