Abstract

The invention belongs to the technical field of high-temperature material, and relates to a non-contact heating method and device for studying the high-temperature anti-oxidation performance of high-temperature material. The method is characterized in that: the heated material is placed on a bracket in a sealed quartz tube; a coil made from a copper tube is wound outside the quartz tube; circularcooling water is filled into the copper tube; a fast alternating magnetic field is applied to the material through the coil by use of a high-frequency oscillation magnetic field generator so as to heat the material; a computer data acquisition and control system is used for adjusting the input power of the high-frequency oscillation magnetic field generator according to the temperature signal so as to obtain the set temperature of the material; and an air inlet and pressure control system connected with a sealing member is used for adjusting the air and air pressure in the quartz tube. Through the invention, quick and accurate heating of the material can be realized, the temperature rise speed, the heating time, the temperature and the like can be automatically adjusted, the greatest heating rate is 500 DEG C / min, and the highest temperature can reach 2000 DEG C.
