Description
Technical Field
The utility model relates to an improved invention of a spheroidizing annealing furnace.
Background
Before cold heading, spheroidizing annealing treatment is carried out on the round steel wire rod formed by hot drawing, so that the metal performance of the round steel wire rod is uniform. Spheroidizing annealing treatment of round steel wire rods is generally carried out in a spheroidizing annealing furnace. But the spheroidizing annealing furnace in the prior art has low production efficiency.
Disclosure of Invention
Aiming at the defects of the prior art, the to-be-solved technical problem of the utility model is to provide a high-efficient spheroidizing annealing furnace which can realize high-efficient production.
The utility model discloses a following technical scheme implements:
high-efficient spheroidizing annealing stove, including shell, heating element, interior bucket, convection current bucket and bell, the inner wall of shell is equipped with the furnace lining heat preservation, forms furnace, its characterized in that in the furnace lining heat preservation: the inner barrel is arranged in the hearth, a round bottom end socket is arranged at the bottom of the inner barrel, the convection barrel is arranged in the inner barrel, a bearing frame is arranged at the bottom of the convection barrel and is supported on the round bottom end socket, a convection space is reserved between the inner barrel wall of the inner barrel and the outer barrel wall of the convection barrel, the heating element is suspended in the hearth and is divided into four areas, the temperature of the upper area, the middle area and the lower area is controlled, the hearth is provided with a cooling air blowing inlet at the position close to the bottom, a cooling air discharging outlet at the position close to the top, the cooling air blowing inlet is communicated with an external cooling fan, the furnace cover can be lifted up and down and is.
Seal through asbestos packing between furnace opening and the bell, furnace's top end face is equipped with the flange seat, and the up end of flange seat is located to the asbestos packing, and the bell compresses tightly the asbestos packing through the dead weight and seals in order to form the oppression.
The spiral arm is arranged above the furnace cover, the rear end of the spiral arm is rotatably arranged on the fixed support, the spiral arm is provided with the air cylinder, the front chain and the rear chain are pulled when the air cylinder acts, and the free ends of the front chain and the rear chain are respectively connected to the front end and the rear end of the furnace cover.
The inner barrel is a wave-shaped barrel body made of stainless steel plates by roll welding.
According to the spheroidizing annealing furnace in the technical scheme, during work, a round steel wire rod to be spheroidized is placed in a convection barrel, then a furnace cover is covered, the furnace cover compresses an asbestos packing through self weight to seal the interior of a hearth, outside air is prevented from entering the hearth, nitrogen gas and the like are filled in the hearth, then a fan wheel at the opening of the hearth performs high-speed air blowing, the air blowing action firstly acts on the convection barrel, then enters a convection space from the bottom of the convection barrel, then comes out of the top of an inner barrel and then enters the convection barrel, convection circulation is formed in the hearth, and as heating elements are divided into an upper region, a middle region and a lower region to control temperature, the lower region has lower temperature and the upper region has higher temperature, the flowing gas entering the convection barrel again keeps even entering and exiting temperature; in addition, the barrel body of the inner barrel is wavy, the heating area is large, the heating efficiency of the heating element to the gas in the gas convection process can be improved, and efficient production is realized. And before the furnace cover needs to be opened after the heat preservation process of annealing treatment is finished, cold air enters the hearth from the cooling air blowing inlet and is then discharged from the cooling air outlet of the hearth through the air blowing action of the cooling fan, so that the hearth is rapidly cooled, and high-efficiency production is realized. Finally, when the furnace cover needs to be opened, the front and rear ends of the furnace cover can be pulled by the front and rear chains through the action of the air cylinder, so that the furnace cover is stably lifted, and after the furnace cover is lifted by a certain height, the furnace cover is rotated and moved away from the upper side of the hearth, so that the feeding or discharging action is facilitated, and the efficient production is realized.
