Combined thermal analysis sampling cup

Abstract

The invention relates to the technical field of thermal analysis, in particular to a combined thermal analysis sampling cup which is used when analysis is performed on molten metal. The combined thermal analysis sampling cup comprises a cup cover and a combined cup body consisting of more than two single cups, wherein the cup cover covers the upper surface of the combined cup body; the lower surface of the cup cover is provided with seams which extend into the cup rims of all the single cups and are matched with the cup rims; the cup cover and each single cup are positioned through each seam, and each seam is fixedly connected with the inner wall of the related cup rim; the cup cover is provided with a pouring opening; pouring passages are arranged beside the seams; and the pouring opening is communicated with a cavity of each single cup through each pouring passage. The experimental sampling workload is reduced for the new material thermal analysis experimental work, and meanwhile, the defect that the thermal analysis curve characteristic parameter cannot be accurately determined due to non-uniform pouring temperature and pouring quality for sampling of a single sampling cup is eliminated.

Description

technical field [0001] The invention relates to the technical field of thermal analysis, in particular to a combined thermal analysis sampling cup used for analyzing molten metal. Background technique [0002] The thermal analysis technology is to pour molten metal into the sample cup, and record the solidification temperature curve of the molten metal in the sample cup through the thermocouple in the sample cup and the data recording and analysis system under the specific heat dissipation conditions of the sample cup. Analyzing, evaluating its structure composition and mechanical performance parameters, thermal analysis technology is widely used in cast iron furnace analysis, including carbon equivalent, carbon silicon determination, cast iron mechanical performance prediction, ductile iron nodularity rate determination, etc. [0003] The traditional thermal analysis sample cup is a single cup, which cannot be quantified when sampling, and cannot pour multiple sample cups a...

Problems solved by technology

[0003] The traditional thermal analysis sample cup is a single cup, which cannot be quantified when sampling, and multiple sample cups cannot be poured at the same time at the same time

The experimental work of thermal analysis of some new materials has brought about an increase in the workload of experimental sampling, and the pouring temperature of multiple samples is inconsistent, and the amount of sampling pouring has errors, which leads to the inability to accurately determine the characteristic parameters of the thermal analysis curve.
