Preparation equipment for high-throughput experiment samples

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.

Description

technical field [0001] The invention relates to a material preparation technology, in particular to a high-throughput experimental sample preparation equipment. Background technique [0002] As we all know, process parameters such as superheating degree, cooling intensity, magnetic field strength and magnetic field form in the material preparation process have a great influence on the structure of the material, and then affect the performance. Most of the traditional experiments on the influence of process parameters on the solidification structure adopt the method of controlling a single variable to conduct experiments one by one. However, the future development of materials must be based on a huge basic database + computer simulation + experiments. Therefore, the above-mentioned traditional experimental methods seem to be stretched. [0003] High-throughput experimental material preparation technology is to complete the preparation and characterization of a large number o...

AI Technical Summary

Problems solved by technology

Most of the traditional experiments to study the influence of process parameters on the solidification structure adopt the method of controlling a single variable to conduct experiments one by one. This kind of research method is too long to accumulate basic data, and the environmental conditions are difficult to accurately control and low in efficiency.

However, the future development of materials must be based on a huge basic database + computer simulation + experiments. Therefore, the above-mentioned traditional experimental methods are stretched.
