Abstract
The invention discloses a resistance material capable of preventing overheat generation caused by excessive current. The main composition of the resistance material is as follows: one or more of microelements, such as Al, Fe, Co and rare earth are added on the basis of NiSiMnTi. The high-temperature life of the prepared resistance alloy can be increased obviously on the condition of ensuring the resistivity.
Description
Technical field
The present invention relates to a kind of resistive material, particularly a kind ofly prevent that electric current is excessive and produce the superheated resistive material.
Background technology
Nickel aluminium heating resistor alloy is applied to the production overheating protection and the accurate overheating protection element of control current overload, prevent effectively (motor, transformer ... etc.) produce because of electric current is excessive overheated.Because electric heating apparatuss such as water dispenser, water-heater, sandwich bread baker, dishwasher, drying machine, sterilizing-cabinet, microwave oven, electric coffee pot, electric caldron, refrigerator, air-conditioning, gluing machine, office equipment, car seat heater are widely used.
Nickel aluminium heating resistor alloy working temperature is about 1200 ℃; Have high hot strength, resistance to high temperature oxidation, heat and corrosion resistant performance when requiring alloy material work, also possess the high reliability of good fatigue property, fracture toughness property, plasticity, structure stability, work etc. simultaneously.The nickel aluminium heating wire material that generally uses generally has two types at present; Corresponding to different overheating protection element models; First kind is the Ni-Si-Mn-Al alloy; 20 ℃ resistivity is 0.31 μ Ω .m; Though the resistivity of this type material satisfies above-mentioned requirements; But the life-span has only 30min in the time of 1250 ℃, can't satisfy the standard of least life 1.5h; Another kind is the Ni-Si-Mn ternary alloy, and 20 ℃ resistivity is 0.23 μ Ω .m, and there is 10h in the life-span during 1200 ℃ of this material, can't satisfy the standard of the desired least life 15h of this overheating protection element.
Summary of the invention
The purpose of this invention is to provide and a kind ofly prevent that electric current is excessive and produce the superheated resistive material that said material is under the situation that guarantees resistivity, high temperature service life is improved significantly.
Of the present inventionly prevent that electric current is excessive and produce the superheated resistive material and form that the mass percentage content of each component is: Si:0.5～3.0% by Ni, Si, Mn, Ti and trace element; Mn:0.02～1.0%; Ti:0.02～0.5%; Trace element: 0.02～1%; Ni: surplus.
The present invention's technical scheme preferably is, said material is made up of Ni, Si, Mn, Ti and trace element, and the mass percentage content of each component is: Si:2.3～2.5%; Mn:0.1～0.5%; Ti:0.05～0.15%; Trace element: 0.14～0.38%; Ni: surplus.
The resistivity that said material is 20 ℃ is 0.19 μ Ω .m～0.25 μ Ω .m, and wherein trace element is one or more in Al, Co, Fe, the rare earth.
Advantage of the present invention is:
1) add the Ti element in the alloy after; Can form tangible intracrystalline to alloy strengthens; Improve the intensity of alloy; At high temperature the Ti element can stop grain fineness number to be grown up simultaneously; Improve the high-temperature stability of alloy; Thereby reach the purpose that improves high temperature service life, the adding of simultaneously a small amount of Ti element is very little to the alloy resistivity effects, also can not cause deterioration to the hot workability of alloy simultaneously.
2) adding of trace element Al, Co, Fe, rare earth except that the intensity that further can produce solution strengthening raising alloy, also utilizes the interaction of alloy element simultaneously, improves the high temperature creep strength of alloy, prolongs the high temperature service life of alloy.
