Abstract

The invention belongs to the field of material mechanical property test, particularly relates to an infrared heating furnace device for heating a material sample in an infrared way, solves the problems that temperature change test is difficult to finish, the heating temperature of a low end is unstable, and the like, and is used for searching the material mechanical property under the conditions of constant temperature and changed temperature. The device is provided with furnace bodies with elliptical cylindrical reflection, infrared heating lamps and temperature controllers, wherein the focusof the elliptical cylindrical surface of each furnace body is provided with an infrared heating lamp; the input ends of the temperature controller are connected with temperature thermocouples extending into the furnace bodies, and the output ends of the temperature controllers are connected to all the infrared heating lamps. The invention is suitable for testing the mechanical properties of a material under different temperatures and continuous changed temperatures and realizes mechanical property test and thermal mechanical property test on the material sample through rapidly heating the material sample to the teat temperature so as to search a method for improving the material property.

Description

technical field [0001] The invention belongs to the field of material mechanical performance testing, and specifically relates to an infrared heating furnace device, which is a device for heating material samples in an infrared manner. Background technique [0002] At present, resistance furnaces are most commonly used for heating samples. The heating time is long and the thermal hysteresis is serious. It is impossible to complete the variable temperature experiment, and the heating at low-end temperatures is often unstable. The temperature test of materials is an important part of material testing, and it has great significance for the use of materials. Contents of the invention [0003] The purpose of the present invention is to provide an infrared heating furnace device, which solves the problems that the variable temperature experiment is difficult to complete, and the heating at the low end temperature is unstable, and is used for studying the mechanical properties of...
