Abstract
The utility model discloses a molybdenum silicide type heater whose heating part is in a rectangular strip shape. The molybdenum silicide type heater is mainly composed of a heating part and two terminal parts which are arranged on two ends of the heating part. The molybdenum silicide type heater whose heating part is in the rectangular strip shape is characterized in that the heating part is rectangular strip shaped molybdenum disilicide which is arranged on initiating two ends of the heating part, and wire connection terminal parts are electrically connected. The surface area of the heating part can be increased through changing the shape of the heating part of the heater under the condition of not increasing raw materials, thereby achieving the effect that the heater irradiates heat to a hearth, and saving energy and resources.
Description
Technical field
The utility model relates to a kind of heater, especially relates to the molybdenum silicide type heater that a kind of heat generating part is rectangular strip.
Background technology
The molybdenum silicide type heater is commonly called as " Si-Mo rod ", mainly is made of molybdenum disilicide.Molybdenum disilicide is with its high melt point (2030 ℃); Fabulous high-temperature oxidation resistance; Moderate density (6.24gcm
- 3); Good electric heating conductibility (resistivity 21.5 * 10
-6Ocm, thermal conductivity 50.0Wm
-1K
- 1) etc. characteristic and become a kind of very potential thermal structure candidate material.At present, molybdenum disilicide the most widely purposes be the heater element that uses as oxidation environment more than 1500 ℃.
Existing molybdenum silicide type heater mainly is made up of heat generating part and portion of terminal two parts on the market, and its heat generating part all is to be processed by cylindrical molybdenum disilicide bar.In all shapes, circular surface area is minimum, thereby in the electric furnace made from existing molybdenum silicide type heater, it is minimum that the molybdenum silicide heater is given the area of radiation of burner hearth heat, the inevitable existence wastes energy and problem of resource, thereby be necessary to change the shape of heat generating part, and increase the area of heat generating part, be rapidly heated to reach, the purpose of energy savings and resource.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of molybdenum silicide type heater is provided, and especially a kind of heat generating part is the molybdenum silicide heater of rectangular strip.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of heat generating part is the molybdenum silicide type heater of rectangular strip, it comprises heat generating part, two binding post portions are arranged at the two ends of heat generating part, it is characterized in that: described heat generating part is rectangular strip molybdenum disilicide, is electrically connected with binding post portion respectively at the initial two ends of heat generating part.
The utility model compared with prior art can produce following good effect: heat generating part processes by rectangular, do not increasing under the raw-material situation, can increase the surface area of heat generating part, thereby increase the swept area of heater to the radiation of burner hearth heat, increase programming rate, energy savings and the resource of electric furnace.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and the embodiments;
Accompanying drawing 1 is the vertical view of a kind of execution mode of the present utility model.
Accompanying drawing 2 is the end view of Fig. 1.
Among Fig. 1: 1. heat generating part; 2. binding post portion; 3. binding post portion.
Embodiment
In Fig. 1 and 2, a kind of heat generating part of the present utility model is the molybdenum silicide type heater of rectangular strip, mainly constitute with two the binding post portions 2,3 that are located at heat generating part 1 two ends by heat generating part 1, it is characterized in that: described heat generating part 1 is rectangular strip molybdenum disilicide, at the initial two ends of heat generating part, be electrically connected with binding post portion 2,3 respectively.Heat generating part 1 is to be processed by rectangular strip molybdenum disilicide, rather than traditional cylindrical rectangular processing.Is example with traditional heat generating part by the cylindrical bar of φ 6mm * 200mm, and its surface area is 3768mm
2With same raw material, if heat generating part is processed into the rectangular strip of 4.71mm * 6mm * 200mm, length is constant, but its surface area is increased to 4248mm
2, be original 112.7%.The utility model can increase the surface area of heat generating part, thereby increases the area of heat generating part to the radiation of burner hearth heat.
