Introduction to the
A kind of alloy, consists of two layers (or layers) with different thermal expansion coefficient of metal or alloy layer components as solid combination and into.A group of thermal bimetal yuan layer with low thermal expansion coefficient, the passive layer;Another group of yuan layer with high thermal expansion coefficient, to active layer.Sometimes, in order to obtain special properties of thermal bimetal, can also join the third or fourth layer metal or alloy.Usually, the passive layer are type invar alloy containing Ni34 ~ 50%;Active layer, the brass, Ni, Fe - Ni - Cr, Fe - Ni - Mn and Mn - Ni - Cu alloy, etc.Through different combination of active and passive layer material, you can get different kinds of thermal bimetal, such as high temperature, medium temperature, low temperature, high sensitive, corrosion resistant, resistance and quick action, etc.
features


According to the characteristic of thermal bimetal main parameters are: (1) than bend.Including all the material characteristics of the amount of thermal bimetal bending.It is to measure thermal bimetal temperature sensitive degree of an important parameter.(2) use temperature range.The temperature range of thermal bimetal can normal work.Including linear temperature range and allows the use of temperature range.In linear temperature range of internal heating bimetallic bending displacement has a linear relation with temperature, maximum value than bending.Allows the use of temperature range than linear temperature range.In this range, although lower than that of bending, but internal thermal stress is still lower than the elastic limit of material, can still be safe to use.(3) the modulus of elasticity.Calculation of thermal bimetal element that generates the thrust, torque and internal stress when the required parameters.(4) the resistivity.Calculation of direct electrical heating thermal bimetal element heating temperature parameters.The most commonly used 3 ni24cr2 (active layer) / 4 j36 layer (passive) for the key features of thermal bimetal: than bending (at room temperature to 150 ℃), (13.2 ~ 15.5) x 10-6 ℃ - 1;Allows the use of temperature range, - 70 ~ + 450 ℃;Linear temperature range, and 20 ~ + 180 ℃;Modulus of elasticity, acuity 16000 KGF/was;Resistivity (20 + / - 5 ℃), 77 ~ 84 mu Ω · cm.


Thermal bimetal thermal expansion coefficients of every different, when the temperature changes the amount of expansion and contraction in every different, as a whole of thermal bimetal element bending will occur.The thermal properties are widely used in the temperature measurement, temperature control, temperature compensation and program control, etc.Thermal relay and circuit breaker in the electrical industry, such as meteorological instrument and meter industry of galvanometer, such as home appliances electric iron, electric cooker, refrigerator and air conditioning devices are widely used in thermal bimetal component.


application
Bimetallic strip: thermal bimetal is composed of two or more than two layers have different linear expansion coefficient of solid combination of alloy composite materials.Large expansion coefficient of the alloy layer is called the active layer, smaller expansion coefficient of the alloy layer is called the passive layer, between active and passive layer can be adjusted with the middle tier of the role of resistance, when the environment temperature changes, because the expansion coefficient of active and passive layer, bending or rotation.This alloy is used for temperature control, temperature compensation, current limit and temperature indicating temperature sensor in automatic control equipment and instrumentation.Can also be applied to the circuit breaker, switch, thermal relay, all kinds of temperature control components, home appliance protector, electronic protector, overload protector, condensate drain device, temperature controller, thermometer, incubator, meteorological instruments, electric iron, electric rice cooker, refrigerator, fire alarm, fluorescent lamp, oven, lighter, the starter current mode control switch automatically, automatic protection switching rules, etc.Also used for fluid (gas, liquid) valve temperature sensor in low voltage electrical switches, etc.
