Abstract
The utility model discloses a spiral electrothermal radiant tube made of white corundum, which comprises a sleeve and an isolating rack. A core is arranged in the sleeve, the isolating rack which is tubular is arranged at the front half section of the core, a plurality of heating elements mounted at the rear half section of the core are in series connection and screw joint, a cross support is arranged between each two of the heating elements which are connected in series, and a base support is mounted at the tail ends of the heating elements. A baffle is mounted on the other side of the isolating rack, and a connecting wire is mounted on the outer wall of the baffle, connected with the heating elements after penetrating through the baffle and the isolating rack and provided with a connecting lug. The sleeve is made of 0Cr25Ni20 heat resistant steel, and the cross supports are made of white corundum. The spiral electrothermal radiant tube made of white corundum has the advantages of novel structure, convenience in manufacturing, installation and detachment, short time for temperature rise, high energy-saving efficiency, capability of reducing cost effectively and prolonging service life.
Description
Technical field:
The utility model relates to the electrothermal radiation tube field, specifically is a kind of white fused alumina spiral electrothermal radiation tube.
Background technology:
Mention electrothermal radiation tube, the noun that this is not strange, be by the U.S. (Abar-Ipsen) Yi Pusen company (afterwards transferring German Ipsen Yi Pusen) at first, at the electrothermal radiation tube of sealed-box type resistance furnace, rotary hearth furnace, single stove and cycle stove research and development, the reform of heat treatment of workpieces played develop by leaps and bounds.China introduces external advanced Equipment for Heating Processing since 82 years parts, electrothermal radiation tube is as the consumable accessory in the sealed-box type resistance furnace, and traditional tube core heater is as a whole, if heater damages, reach integral body and scrap, and the inconvenient installation and removal of cross bearing support.The utility model adopts a plurality of heater series connection to screw, and is equipped with the cross bearing support between per two, even one of them heater or cross bearing support damage, can remove and install easily, has effectively saved cost, has prolonged the useful life of tube core.
The utility model content:
The purpose of this utility model provides a kind of white fused alumina spiral electrothermal radiation tube, and the problem that the heating efficiency that has solved traditional electrothermal radiation tube is low, installation and removal are inconvenient has reduced cost effectively.
The technical solution of the utility model is as follows:
White fused alumina spiral electrothermal radiation tube, comprise sleeve pipe, isolating frame, be provided with tube core in the described sleeve pipe, tube core is provided with isolating frame for preceding half section, isolating frame is a tubular, it is characterized in that: the described second half section is equipped with the series connection of several heaters and screws, and is provided with the cross bearing support between per two of a plurality of heaters of series connection, and the heater end is equipped with the base support frame; Described isolating frame opposite side is equipped with baffle plate, and the baffle plate outer wall is equipped with wiring, and baffle plate is passed in wiring, isolating frame is connected with heater, and described wiring is provided with connector lug.
Described white fused alumina spiral electrothermal radiation tube is characterized in that: described shell material adopts 0Cr25Ni20 heat resisting steel, and it is white fused alumina that described cross bearing support adopts material.
Through test of many times and research,, obtain good result to doing courageously reform on the performance of electric radiation and the structure:
One. the expansion factor of splashing is complementary:
Improve the original prescription of GB-95 corundum bearing support, make electric heating element and GB-95 corundum bearing support adopt the synchronous heat expansion factor of splashing, effectively avoid the electric radiation high temperature deformation.
Two. process structure optimization:
Change original tactic pattern, change cross corundum bearing support into by original circular corundum bearing support, make electrothermal radiation tube corundum bearing support small size contact heat resisting steel sleeve pipe, give full play to the heating efficiency of electrothermal radiation tube, prolong the useful life of electrothermal radiation tube effectively.
Three. in addition, traditional tube core heater is as a whole, if heater damages, reach integral body and scrap, and the inconvenient installation and removal of cross bearing support.The utility model adopts a plurality of heater series connection to screw, be equipped with the cross bearing support between per two, even one of them heater or cross bearing support damage, can remove and install easily, effectively saved cost, prolonged the useful life of tube core, the utility model is widely used in heat-treatment production lines such as single stove, cycle stove, rotary hearth furnace, sealed-box type multipurpose furnace.
