Abstract
The utility model discloses a heating element of a resistor furnace, which has the advantages of simple manufacture, material conservation and convenient use and maintenance. The heating element comprises a heating element (5) and is characterized in that the heating element (5) is strip-shaped bar-shaped, and a heating element group is formed by two or more than two heating element (5). The heating element provided by the utility model has the advantages of simple processing as well as energy and material conservation. Besides, if the heating element has partial abnormal damage in the use process, people only need to replace damaged parts, and the rejection of the entire heating element is avoided; and the production and manufacturing cost can be saved.
Description
Technical field:
The utility model relates to a kind of resistance furnace, specifically a kind of resistance furnace heater.
Background technology:
At present, the material that the resistance furnace heater is commonly used has metal and nonmetal two big classes.The metal electric heating element material has nichrome, Cr-Al alloy, tungsten, molybdenum, tantalum etc., is made generally in helix, wavy line, waveform band and corrugated sheet.The non-metal electric heating element material has carborundum, molybdenum disilicide, graphite and carbon etc., is made generally in shapes such as rod, pipe, plate, band.Heater in the single crystal growing furnace that generally uses as CVD cvd furnace, photovoltaic industry adopts the non-metal electric heating element material, generally adopts three high graphite machine works to form.Add man-hour, need earlier monoblock three high graphite middle parts to be hollowed out and be machined to cylinder, then on cylinder equably, respectively open some flow-guiding radiation grooves up and down, cylinder is divided into waveform, heater is as a whole, and it is more to add the man-hour consumptive material, wastes time and energy, in addition, because the graphite mechanical property is relatively poor, its product strength is low, and thermal shock resistance is bad, be easy to generate micro-crack even fragmentation in the rapid heat cycle environment under external force or repeatedly, as long as heater has local damage, will influence its electricity and thermodynamic property, cause whole heater to be scrapped, influenced normally carrying out of producing, the production cost of enterprise is increased.
Summary of the invention:
The purpose of this utility model provide a kind of make simple, save material and use resistance furnace heater easy to maintenance.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of resistance furnace heater, and it comprises heater, heater is a strip or bar-shaped, and forms the heater group by the heater more than 2 or 2.
The set of heater described in the utility model or heater group is the birdcage shape, and birdcage is circular or square.
Heater in the heater group described in the utility model is a serial or parallel connection.
The cross section of heater described in the utility model is the some of rectangle, circle or annulus.
Heater described in the utility model is processed into by graphite or carbon/carbon compound material.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, heater processing is simple, energy-conservation province material, in addition, in use if the situation that local anomaly is damaged occurs, the part that need only change damage gets final product heater, can not cause whole heater to scrap, can save manufacturing cost.
