Abstract
The invention discloses preparation equipment for high-throughput experiment samples. The preparation equipment comprises an induction coil and the like. Automatic program control is carried out through a computer and a programmable controller, a mechanical pump is started for vacuum pumping, a gas inlet valve is opened to introduce high-purity argon or nitrogen, a medium-frequency induction power source is turned on to introduce medium-frequency current into the induction coil for induction heating, a rotary table is rotated in a forward-backward crossed mode, samples are stirred at a small angle, the medium-frequency induction power source is turned off after the samples are molten to be uniform, a single-pole double-throw switch is connected with a pulse power source, and the pulse power source is turned on for carrying out pulse magnetic field treatment on a sample solidification process; in the sample solidification process, the gas flow of the gas inlet valve and a gas outlet valve is accurately adjusted through temperature feedback of the programmable controller and a thermocouple, the cooling rate is controlled to be in the range of 10<-2>-10<2> K/s, and a batch of solidified samples with different ingredients and different cooling rates are obtained at a time. The preparation equipment can be used for rapidly screening optimal sample ingredients, solidification structures and technological parameters.
