introduction： Induction heating：The workpiece is placed in the sensor，The sensor is usually input medium frequency or high frequency alternating current (300-300000HzOr higher)Hollow copper pipe。An alternating magnetic field is generated to generate an induced current of the same frequency in the workpiece，The distribution of this induced current in the workpiece is not uniform，Surface strength，And its weak on the inside，Close to the heart0，Take advantage of the skin effect，The surface of the workpiece can be heated rapidly，In a matter of seconds the surface temperature rises to800-1000℃，The increase in heart temperature is very small。 Selection of induction heating frequency：Per heat

introduction：In order to makeKOYOLarge compressive stress remains on the surface of bearing parts after quenching and tempering，An atmosphere of carburizing or nitriding can be used during quenching heating，Perform short periods of surface carburizing or nitriding。Because the actual carbon content of austenite is not high when this steel is quenched，Well below the equilibrium concentration shown on the phase diagram，So it absorbs carbon（Or nitrogen）。When austenite contains higher carbon or nitrogen，itsMsreduce，Martensitic transformation occurs in the surface layer after the inner layer and the core during quenching，A large residual compressive stress is generated。GCrl5The steel is heated and quenched in carburizing atmosphere and non-carburizing atmosphere(All are tempered at low temperature)After treatment,It can be seen from the contact fatigue test

introduction：The upper silver guide rail is a linear guide rail，When using linear guide rails as linear guides，Because the friction mode of linear slide rail is rolling friction，Not only is the friction coefficient reduced to slide-guided1/50，The difference between dynamic friction and static friction force also becomes very small。

introduction：The uniform wear of the silver guide rail has a great influence on the working life of the parts。For example, on the silver rail，If the wear is even，It generally has little effect on the machining accuracy。

introduction：The difference between spheres and aspheres So called spheres and aspheres，Mostly for the camera（Various successively、microlens）、Glasses（Including contact lenses）In terms of lens geometry，Spherical lens and aspherical lens。The difference in geometry between the two determines that they differ in the direction of refraction of parallel incident light，Thus affect the quality of its imaging effect。 Spherical lens，The lens has a spherical arc，The transverse plane is also curved。When different wavelengths of light，When incident at different locations on the rear lens with parallel optical axes，On the film plane（Perpendicular to the lens center and lens focal link、Through focus

introduction：1 introduction With the rapid development of economy，Expressways have been playing an important role in transportation，Whether it works or not matters。Statistical analysis of highway traffic accidents according to relevant data，Found in driver—CARS—Road in three links，Drivers are the least reliable，80％The above accidents are caused by the drivers late response or poor judgment；Especially when cars are traveling at high speeds，Correct identification of the target ahead is crucial，The weather or the drivers fatigue will affect the drivers recognition of the target in front，And with the continuous increase of car ownership，How to improve the flow of roads

introduction：1.CATIA The surface of "trait"The way to manage. 2.The function of each constructed surface is a feature and each feature can contain several surfaces，That is, each feature can represent more than two connected surfaces or more than two connected curves。 3.Each instruction takes"trait"To operate rather than to operate by the number of surfaces。 4.Each feature is the order of construction，This is kind of like an entity，But its not as mandatory as an entity，In the entity character is there is a forced order problem，There is no such limitation in the use of curved surfaces is more flexible，But it can be arranged at the end by paternity

introduction：byVoest-Alpine Stahl LinZ GmbHThe developed roller torque measuring device is installed in the ingot bar，Slab continuous casting，Measure and record the torque of each roller under load。Generally in the case of slab continuous casting，In the width direction by3Part of the roller table，To measure all rollers on the inside and outside，Because each roller table part requires a torque sensor unit，You need complete mechanical and electrical separation6Table torque sensor and data recording unit。The torque sensor is pressed against the roller with a spring plate。The strain gauge mounted on the torque sensing unit is used to measure the torque of the roller wheel

introduction：Each drying device has its specific scope of application，For each material, several drying devices can be found that can meet the basic requirements,But there can only be one best fit。In case of improper selection，Users in addition to bear unnecessary one-time high procurement costs，But also pay a heavy price throughout the service life，Such as inefficiency、High energy consumption、High operating cost、Poor product quality、Even the device does not work properly and so on。 The following is the general principle of drying device selection，It is hard to say which item or items are the most important，The ideal selection must be focused on their own conditions，Sometimes compromise is necessary。
