Temperature tester is widely used in various industries, but also widely used in the automotive industry, according to the temperature tester can be determined at the time of production for the best temperature is how much, so that we can produce quality reliable temperature tester in the best environment, heat temperature tester has its own characteristics to us look at it!
The application of heat treatment temperature tester in the international automobile hub like Mercedes Benz and BMW Aluminum Alloy heat treatment, bestemp thermometer is 6/10/15 channel three series, can fully meet the electronic assembly, auto spraying, heat treatment, annealing and other ceramic wheel test requirements. Here is the analysis of characteristics of the heat treatment temperature tester.
Automotive parts are Aluminum Alloy wheels, engine block, cylinder head, intake manifold, a new generation of piston. The development of new type aluminum alloy is mainly focused on the aspects of melt treatment, alloy development, casting technology, heat treatment and machining. Aluminum Alloy wheel is "light", "high speed" and "modernization" of the product, Aluminum Alloy wheel is more beautiful, but also has the characteristics of light weight, energy saving, good heat dissipation and corrosion resistance, the development direction of the wheel is of lightweight, high balance and high strength and toughness.
The process specifications of the wheel heat treatment plant Aluminum Alloy: solution treatment (535 + 5) C, holding 3-4 hours, quenching medium, quenching temperature is 60 degrees, the duration is less than 15 seconds, aging treatment (160 + 5) C, holding 3-4 hours. The specific process according to the size and heat treatment equipment for appropriate adjustments.
The heat treatment process parameters is not correct, the casting mechanical properties after heat treatment appear unqualified, burning, deformation and cracking and other defects, the reasons are: solid melt temperature is low or the holding time is not enough, can not fully into the strengthening phase alpha Al of water quenching when the cooling speed is not enough. The wheel from the furnace to the quenching tank transfer time is too long, more than 15 seconds. Aging temperature is too low or holding time is not enough. The solution temperature is high or the holding time is too long, grain boundary junction of the low melting point eutectic melts, the liquid phase, under the effect of surface tension, liquid phase contraction into ball shape or polygonal, spherical complex melt, severe burn, will melt in the complex annular strip, all boundaries and even on the wheel surface nodules. The mechanical properties of the advertising wall alloy can not be repaired when the over burned tissue appears.
