Abstract
The utility model discloses amolybdenum disilicide heating element with a plurality of heating portions, which comprises a heating portion, a terminal portion for transmitting current and at least a connecting portion, and is characterized in that the initial two ends of the heating portion are respectively connected with the connecting portion and the terminal portion through a butt weling mode. The heating portion mainly generates heat when the heating element is used, and the same heating element is provided with a plurality of heating portions. The molybdenum disilicide heating element can give the same hearth two relatively-independent portion, adopts the same heating element for supplying heat, and can supply different heat according to the different diameters of the heating portion, and reaches the purpose that the same hearth has different temperatures in different zones.
Description
Technical field
The utility model relates to a kind of heating element, especially relates to a kind of molybdenum disilicide class heater element with a plurality of heating parts.
Background technology
At present, to use the most widely be as the heater element in the electric furnace to molybdenum disilicide.Molybdenum silicide heating element has excellent high-temperature oxidation resistance, and it is very fast that unique resistive performance can make furnace temperature raise, and resistance is just not aging not with changing service time, so the old and new's element can mix use.In the electric furnace made from molybdenum silicide heating element, can realize low energy consumption, be rapidly heated, hang down maintenance expense, clean environment and stable product characteristics.Molybdenum silicide heating element has been used on the large scale industry electric furnace, is one of capital equipment of industries such as metallurgy, electronics, glass, pottery and magnetic material.
But existing molybdenum silicide heating element mainly is made of with the binding post portion that is located at the two ends, heating part a heating part, and heater element generally is shapes such as U, W, L.The electric furnace made from this heater element is difficult to realize the different temperatures zone in same electric furnace, can not control different electric furnaces with identity element.Along with the progress and the requirement of enterprise of science and technology, the kind of electric furnace is more and more, thereby is necessary to design a kind of molybdenum silicide heating elements, adopts one group of molybdenum silicide heating element to heat simultaneously and control a plurality of zones of a plurality of electric furnaces or an electric furnace.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of molybdenum disilicide class heater element that can heat simultaneously and control a plurality of zones of a plurality of electric furnaces or an electric furnace is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of molybdenum disilicide class heater element with a plurality of heating parts, it comprises that heating part, the portion of terminal of carrying electric current and at least one connecting portion constitute.The initial two ends that it is characterized in that the heating part are connected by the butt welding mode with connecting portion and portion of terminal respectively, and in the heater element use, the heating part produces heat, and connecting portion does not generate heat, and same heater element has a plurality of heating parts.
The utility model compared with prior art can produce following good effect: include a connecting portion in a heater element at least, thereby include two independently heating parts at least, at least can give two relatively independent parts of same burner hearth, perhaps the burner hearth of two placed adjacent adopts same group of heater element supply heat.And can provide different heats according to the difference of heating part diameter, reach the purpose of different temperatures.Satisfy modern industry quantity-produced demand, and can realize continuous kinds of processes processing.
Description of drawings
Fig. 1 is first kind of execution mode of the present utility model.
Fig. 2 is second kind of execution mode of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Embodiment 2, a kind of molybdenum disilicide class heater element (referring to Fig. 2) with a plurality of heating parts, it is by two portion of terminal (1,2) of carrying electric current, and three heating parts (3,4,5) and two connecting portions (6,7) are formed.Heating part (3) has identical diameter with heating part (4), and heating part (5) have different diameters with heating part (3,4).
Claims (2)
1. molybdenum disilicide class heater element with a plurality of heating parts, it comprises the portion of terminal (1,2) of carrying electric current, heating part (3,4) and at least one connecting portion (5) constitute, and it is characterized in that the initial two ends of heating part (3,4) are connected by the butt welding mode with connecting portion (5) and portion of terminal (1,2) respectively.
2. according to claim 1 described a kind of molybdenum disilicide class heater element with a plurality of heating parts, it is characterized in that: described connecting portion (5) has identical diameter with the portion of terminal (1,2) of carrying electric current.
