Abstract

The invention belongs to the material performance test technology field and discloses a high temperature tensile test resistance furnace capable of controlling a cooling process. The resistance furnace comprises a stretching machine, a cooling resistance furnace, a power device, a condensing device and the like. The cooling resistance furnace comprises a heating inner cavity, a cooling layer and an insulation layer. The cooling resistance furnace is installed on the stretching machine through a rotating shaft and a support, and bent cooling pipelines are laid in the cooling layer, and are connected with an external power device and the condensing device to form a recyclable system. A gap between the cooling pipelines is filled with a flexible insulation material so as to ensure that the pipelines have a certain deformation space. In the invention, the cooling pipelines in the cooling layer, the external power device and the condensing device form a recyclable cooling system, and a cooling medium carries out circulation flow in the cooling system for heat exchange so as to achieve rapid cooling during a test process and control a cooling rate.

Description

technical field [0001] The application belongs to the technical field of material property testing, and in particular relates to a resistance furnace for high-temperature tensile testing that can control the cooling process. Background technique [0002] Due to the advantages of light weight, good seismic performance, convenient construction and short construction period, steel is widely used in building structures. Fire is a common hazard to building structures. At present, most of the research focuses on the mechanical properties of steel in the heating section of the fire. Therefore, the current high-temperature tensile test resistance furnace can only control the temperature rise, but cannot control the temperature drop. However, the steel structure that can withstand the fire heating section may be further damaged or even collapsed in the fire cooling section. Therefore, it is very necessary to study the mechanical properties of steel in the cooling section of fire. ...
