Abstract
The utility model discloses an electric conducting board for a sintering furnace, which is characterized in that: the electric conducting board comprises an electric conducting board which is connected with a power supply, a wiring board which is connected with the sintering furnace, and a bolt which passes through the electric conducting board and the wiring board; the electric conducting board is made of aluminum; and furthermore a copper layer is plated on the surface of the electric conducting board. According to the electric conducting board, material cost is reduced; relatively rare and expensive copper material is replaced by aluminum material which is abundant and has low cost, thereby facilitating protection for rare copper resource; and high practicability and high popularization value are realized.
Description
Technical field
The utility model relates to a kind of conductive plate structure, relates in particular to a kind of conductive plate structure for sintering furnace.
Background technology
Vacuum sintering furnace is the capital equipment of sintering circuit in powder metallurgy manufacture process, adopts low-voltage alternating-current electric heating, because temperature-rise period is to carry out under higher current density, therefore, adopts copper coin conduction between power supply and sintering furnace.Taking 500kg sintering furnace as example, employing be that cross section is that 60mm × 6mm, length are about the copper coin of 1.5 meters, and have 3, weight reaches 9.6kg.Copper mine is the narrow resources of China, and price is also higher.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of conductive plate structure for sintering furnace.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of conductive plate structure for sintering furnace, it is characterized in that: comprise the conductive plate that is connected with power supply, be connected in the terminal block of sintering furnace and run through the bolt that connects conductive plate and terminal block, described conductive plate adopts aluminum to do, and the plated surface of conductive plate is provided with layer of copper layer.
Conductive plate employing aboundresources, the fine aluminium manufacture that low lattice are cheap, and in surface of pure aluminum plated with copper, to improve the attractive in appearance and decay resistance of conductive plate.The two ends of conductive plate are connected with wiring place of power supply, sintering furnace respectively, and fix with bolt.Ensureing that under the prerequisite that electric conductivity is constant, the sectional area of fine aluminium conductive plate is 1.667 times of copper conductive plate.
At present, aluminium cable can not replace the main cause of copper cable to be, elongation and the tensile strength of aluminium are lower than copper, more easily fracture.If fine aluminium is used on sintering furnace as conductive plate, because after fine aluminium conductive plate is fixed between sintering furnace and power supply, generally can not move, thus there is not the problem fractureing, and the sectional area of conductive plate reaches 60mm × 10mm, very firm.
Known from institute, the resistivity of fine aluminium is about 60% of copper, its proportion only has 30.34% of copper, as calculated, the resistance of the copper of 1.978 Unit Weights is identical with the resistance of the fine aluminium of 1 unit mass, in the time that the sectional area of fine aluminium conductor is 1.667 times of copper, its electric property is identical, has realized the dam amount identical with copper, resistance and the loss of voltage.Therefore, adopting sectional area is that the fine aluminium of 1.667 times of original copper conductive plate is made conductive plate.Now, the weight of fine aluminium conductive plate only has 50.5% of copper conductive plate, and again because the unit price of aluminium only has 38% of copper, therefore, the material cost of fine aluminium conductive plate only has 19% of copper conductive plate, i.e. cost 81%.
Compared with prior art, the utility model has the advantage of: the conductive plate structure of employing both can ensure electric conductivity, reduced again conductive plate material cost; Adopt abundant, the low-cost aluminium of reserves to replace relatively rare, expensive copper material, be conducive to protect copper ore resource in short supply.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Figure 1, the conductive plate structure for sintering furnace the utility model proposes, comprise conductive plate 1, the terminal block 2 that is connected in sintering furnace being connected with power supply and run through the bolt 3 that connects conductive plate 1 and terminal block 2, described conductive plate 1 adopts aluminum to do, and the plated surface of conductive plate 1 is provided with layer of copper layer 12.
In the utility model, the sectional area of conductive plate is 1.667 times of original copper conductive plate, and now, the electric conductivity of material is constant, but manufacturing cost declines 81% than copper conductive plate.
Above-described embodiment has only been expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the utility model patent and protection range should be as the criterion with appended claims.
