  7050 medium-thick alumina plate, 7A 04 medium-thick alumina plate, LY12-CZ medium-thick alumina plate, 6A 02 medium-thick alumina plate, 7075 medium-thick alumina plate, 6063 medium-thick alumina plate, alloy medium-thick alumina plate, 5754 medium-thick alumina plate, hard medium-thick alumina plate, die medium-thick alumina plate, machined medium-thick alumina plate, oil tank medium-thick alumina plate, etc. 1 The decarbonization and decarbonization of alumina plate is due to the phenomenon and reaction of partial loss of carbon in the outer layer due to the effect of surrounding atmosphere when steel parts are heated or insulated. Decarburization of steel not only results in hardness deficiency, quenching, heat treatment deformation and chemical heat treatment defects, but also has a great influence on fatigue strength, wear resistance and die performance. The reason for the lack of toughness of alumina plate may be that the quenching temperature is too high and the holding time is too long, which causes the grain coarsening or stops tempering because the tempering brittle zone is not avoided. 3. When there is a large amount of retained austenite in the workpiece, the tempering transformation occurs under the action of grinding heat, which results in the microstructural stress of q355c square pipe and the cracking of the workpiece. The preventive measures are to stop cryogenic treatment or repeated tempering after quenching (die tempering is usually 23 times, even for cold working low alloy tool steels) to minimize the amount of retained austenite. 4. In the manufacturing of crack dies caused by EDM of alumina plate, EDM (electric pulse and wire cutting) is more and more widely used. However, with the widespread application of EDM, the defects caused by EDM increase correspondingly. Because EDM is a processing method that solidifies the surface of dies by means of high temperature generated by discharge, the surface of the dies formed a white EDM degeneration layer and produced about 800 MPa of tensile stress. In this way, defects such as deformation or cracks often occur in the process of dies'EDM. Therefore, it is necessary to fully control the influence of EDM on die data and take corresponding preventive measures in advance. This is a quality problem often presented in alumina board. As for alumina board, we should strengthen its advantages and characteristics in all aspects. We should pay special attention to the purchase time. In this way, alumina board can prevent these defects and be deceived when it is purchased.
