introduction： Welding method using chemical reaction heat as heat source。When welding﹐The ends of the two workpieces to be welded are fixed in the mold in advance﹐Then mix aluminum powder with iron oxide powder(Called thermite)Heat in a crucible﹐A reductive exothermic reaction occurs﹐Become a liquid metal(iron)Fusion slag(Mainly forAl2O3)﹐Injection mold。The liquid metal flows into the joint void﹐Weld metal﹐The slag floats to the surface。To adjust the melt temperature and weld metal chemistry﹐Appropriate additives and alloys are often added to thermite。figure Thermite welding of rail Aluminum for the rail

introduction： Rolling bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Failures are often due to a variety of factors，All design and manufacturing process factors influence andIKOBearing failure，Their analysis is not easy to determine。Under normal circumstances，In general，You can consider and analyze factors and internal factors。

introduction：（1）Annealing cooling system：Steel annealing time，Generally used with the furnace cooling to600～550℃Then the oven is air-cooled。 （2）Normalizing cooling method：When steel normalizes，It is generally cooled in air。 （3）Quench cooling system：Steel hardening，Steel is in the most unstable range of supercooled austenite（650～550℃）The cooling rate should be greater than the critical cooling rate，Thus, the workpiece is not transformed into pearlescent structure；While...MsThe cooling rate near the point should be as low as possible，Thus reducing the quenching internal stress，Reduce workpiece deformation and cracking。therefore，At quenching，In addition to the selection of appropriate quenching cooling agent

introduction：Stress concentration A class of problems in elasticity﹐A local increase in stress in an object﹐It usually occurs where the shape of an object changes rapidly﹐Like a notch﹑opening﹑Grooves and rigid restraints。Stress concentration can cause fatigue cracks in objects﹐It can also cause static load fracture of parts made of brittle materials。Where the stress is concentrated﹐Maximum stress(Peak stress)It is related to the geometry of the object and the loading method。The locally increased stress decreases rapidly with the increase of distance from the peak stress point。Because the peak stress often exceeds the yield limit(See mechanical properties of materials)It causes a redistribution of stress﹐the

introduction： Brake fluid in an electric forklift 1、Note the following when using brake fluid；Alcohol brake fluid has high viscosity at low temperature，Do not use in cold areas；In such cold areas, only synthetic brake fluid can be used；Alcohol brake fluid has a lower boiling point，It is easy to produce gas resistance under high temperature working conditions；Brake fluid must be checked before use，If found white precipitate、impurity，Should be strained before use；Alcohol brake fluid is easy to play、inflammable，The packing should be sealed.，Pay attention to fireworks in storage and use；Synthetic brake fluid absorbs water easily，Pay attention to seal，Do not store in the open，
