Abstract

The invention relates to a method for erasing temperature gradient in mental plate with sample heat treating experiment, which is characterized in that it adds infrared radiation heating means based on the mode of directly using the resistance to heat; it fixes infrared heating apparatus on the two sides of the sample near the clamp, and uses the infrared radiation energy of the infrared heating apparatus to compensate the heat leaked by heat transmitting; it separately controls the directly resistance heating and the infrared radiation heating.

Description

Technical field

[0001] The invention relates to the technical field of metal heat treatment, in particular to a method for eliminating temperature gradients in heat treatment tests of metal strip samples. Background technique

[0002] At present, many material physical simulation equipment such as thermal simulation experiment machine, cold-rolled strip continuous annealing simulation experiment machine, etc., in order to achieve the purpose of rapid metal heating, usually use direct resistance heating, that is, use a heating transformer to provide a certain voltage to the sample. A large current is passed through the sample, and the resistance of the sample itself is used to achieve the purpose of heating. Since the sample is clamped between two water-cooled clamps, a large temperature gradient is likely to occur due to heat conduction ΔT = ( 2 x L ...
