Abstract
The invention discloses a well-type resistance furnace which comprises a furnace lining, a furnace shell, a furnace cover and a furnace bottom. The upper end and the lower end of the furnace lining are fixedly connected with the furnace cover and the furnace bottom respectively through the furnace shell, a thermoelectric couple device is arranged at one end of the furnace lining, and the furnace lining comprises a fiber back lining plate, a thermal insulation fiber blanket and a vacuum forming block. The fiber back lining plate, the thermal insulation fiber blanket and the vacuum forming block are sequentially and fixedly connected form right to left, an electric heating element is further arranged on the vacuum forming block, and the electric heating element is fixedly connected to the vacuum forming block. According to the well-type resistance furnace, the furnace lining is composed of the vacuum forming block, the fiber blanket and a fiber felt, in the high-temperature environment, the obvious cracks and the overtemperature phenomenon of the outer wall can not appear in the furnace wall, and the well-type resistance furnace is good in performance and long in service life. The electric heating element is directly and fixedly connected to the vacuum forming block by the adoption of the pre-buried mode, the pre-buried mode enables the radiant efficiency of the electric heating element to be high, the service life is prolonged, and the well-type resistance furnace is safe and reliable.
Description
Technical field
The present invention relates to a kind of well formula resistance furnace, relate in particular to a kind of for the heat treated well formula of large-scale long shaft resistance furnace.
Background technology
Well formula resistance furnace is the heat treated key equipment of the medium-and-large-sized major axis of China's equipment manufacture, and the growth requirement amount of nuclear power generating equipment increases rapidly especially in recent years, and well formula resistance furnace technology is had higher requirement.The well formula resistance furnace of China exists some problems installing of furnace lining structure and heating always, and is especially particularly serious on the rounded well formula resistance furnace of body of heater.
The structure of furnace lining is made of traditional tapetum fibrosum and fiber folded piece, the installation of heating is to adopt the pottery nail to insert the mode of fixing behind the fiber folded piece, when causing resistance furnace in 1100 ℃ high temperature, to carry out work, tangible crackle and outer wall overheating problem can appear in the furnace wall, poor performance, service life is short, and the installation of heating adopts the pottery nail to fix mostly, because pottery nail hook is heavy, it takes up room greatly, cause easily directly to touch after the heating distortion to cause short circuit, and install inconveniently, fracture easily during installation.
Summary of the invention
Technical problem at above-mentioned existence the objective of the invention is: proposed a kind of Stability Analysis of Structures, the well formula resistance furnace of long service life.
Technical solution of the present invention is achieved in that a kind of well formula resistance furnace, comprises furnace lining, furnace shell, bell and furnace bottom, and described furnace lining top and bottom are fixedly linked by furnace shell and bell and furnace bottom respectively, and described furnace lining one end is provided with thermocouple assembly; Described furnace lining comprises fiber backer board, heat insulation tapetum fibrosum and vacuum forming piece; Described fiber backer board, heat insulation tapetum fibrosum and vacuum forming piece are fixedly linked from right to left successively; Also be provided with electrical heating elements on the described vacuum forming piece; Described electrical heating elements is fixedly connected on the vacuum forming piece.
Preferably, the quantity of described electrical heating elements is four, and is evenly distributed on the vacuum forming piece.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
Well formula resistance furnace of the present invention, furnace lining is made of vacuum forming piece, tapetum fibrosum and fibrofelt, like this in hot environment, the furnace wall just tangible crackle and outer wall overheating problem can not occur, and is functional, long service life, what heating adopted is directly to be fixedly connected on the vacuum forming piece by pre-buried mode, such mode makes the radiation efficiency height of heating, and increase service life, and reliable and secure.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of well formula resistance furnace of the present invention;
Wherein: 1, furnace shell; 2, bell; 3, furnace bottom; 4, thermocouple assembly; 5, fiber backer board; 6, heat insulation tapetum fibrosum; 7, vacuum forming piece; 8, electrical heating elements.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of well formula resistance furnace as shown in Figure 1 comprises furnace lining, furnace shell 1, bell 2 and furnace bottom 3, and described furnace lining top and bottom are fixedly linked by furnace shell 1 and bell 2 and furnace bottom 3 respectively, and described furnace lining one end is provided with thermocouple assembly 4; Described furnace lining comprises fiber backer board 5, heat insulation tapetum fibrosum 6 and vacuum forming piece 7; Described fiber backer board 5, heat insulation tapetum fibrosum 6 and vacuum forming piece 7 are fixedly linked from right to left successively; Also be provided with electrical heating elements 8 on the described vacuum forming piece 7; Described electrical heating elements 8 is fixedly connected on the vacuum forming piece 7; The quantity of described electrical heating elements 8 is four, and is evenly distributed on the vacuum forming piece 7.
Well formula resistance furnace of the present invention, furnace lining structure is made of for three layers by liner plate, heat insulation tapetum fibrosum and vacuum forming piece fiber, be respectively vacuum forming piece, tapetum fibrosum and fibrofelt from the inside to surface, like this in hot environment, tangible crackle and outer wall overheating problem just can not appear in the furnace wall, functional, long service life, what heating adopted is directly to be fixedly connected on the vacuum forming piece by pre-buried mode, such mode makes the radiation efficiency height of heating, increase service life, and reliable and secure.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that spirit essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
