Problems solved by technology

During the long-term high-temperature working process, due to the continuous high temperature and poor contact between the furnace wire and the electrode, the furnace wire of the high-temperature furnace will be oxidized and disconnected.
Once a section of the furnace wire in the high-temperature furnace is disconnected, the temperature of this section will drop immediately, and the high-temperature creep test cannot be continued. The resulting test error is irrecoverable, and the performance data of the material needs to be re-evaluated. It causes a great waste of resources. Therefore, it is of great significance to ensure the long-term continuous operation of the heating furnace wire of the creep durability testing machine for the long-term creep durability performance test of metal materials.

Abstract

The invention provides faulted heating furnace replacement equipment for a creep durability testing machine. The faulted heating furnace replacement equipment comprises a trial furnace assembly, a standby furnace assembly and a thermal-insulating device and is characterized in that with the adoption of positioning design of a standby furnace trolley and bracket rails, a heating furnace can be quickly moved to be in the position of a trail furnace and is in butt-joint with an opening of the trial furnace when the trail furnace is faulted, and the trial furnace and the standby furnace are quickly exchanged after accurate positioning. Two temperature fields are combined into one after the trial furnace and the standby furnace are in butt-joint due to the reasonable design of thermal-insulating plates, and accordingly, the temperature of the heating furnace is guaranteed during replacement. The faulted high-temperature heating furnace replacement equipment solves the problem of test interruption caused by fault of the heating furnace when the creep durability testing machine works continuously for a long time, and the service life of the heating furnace can be effectively prolonged infinitely theoretically. The equipment is simple to use and feasible, can be easily used for high-temperature heating furnaces for the creep durability testing machine and other electric heating wire heating equipment and can realize industrial production.

Description

technical field [0001] The invention belongs to the field of testing and analyzing the mechanical properties of metal materials, especially the long-term continuous creep durability performance of 100,000 hours or more, and specifically relates to a heating furnace failure replacement device for a creep durability test machine. Background technique [0002] When a solid material is kept at a certain temperature and the stress remains constant, the phenomenon that the strain increases with time is called creep. The creep behavior of materials is the result of the joint action of time, stress, and temperature. As long as the acting time is long enough, creep can also occur when the stress is much smaller than the elastic limit. Similarly, the creep behavior of materials also occurs at low temperatures, but it becomes significant only when a certain temperature is reached, which is called the creep temperature of the material. The creep temperature of various metal materials i...
