Embodiment

[0018] 1. Design a heating furnace for high temperature fatigue test of thin-walled plate samples. The overall dimensions are: height 50mmX width 60mmX depth 60mm, the shell of the heating furnace is a cuboid, the size is: height 90mmX width 150mmX depth 150mm, the size of the installation groove for installing the plate sample is: width 60mmX depth 10mm.

[0019] 2. The strip-shaped silicon carbide heating element is adopted, the size is: width 12.5mmX length 50mm, two groups are placed up and down, each group of heating elements can provide a maximum power of more than 600W, and the sample is heated to the working temperature within 30 minutes 1200°C. By connecting the temperature control system, the two sets of heating elements form the upper and lower two-stage heating system in the heating chamber of the heating furnace, so as to realize the automatic adjustment of the temperature gradient during the heating process and form the optimal temperature deviation at the sample...

Abstract

The invention belongs to an aero-engine material performance testing technique and relates to a plate sample fatigue test heating furnace for high-temperature stress fatigue tests of small-size thin-wall samples (length*width*thickness: 180mm*50mm*3mm). The heating furnace adopts a silicon carbide heating element and a three-thermocouple technique, wherein one thermocouple is a sample temperature measuring thermocouple and is used for measuring actual temperature of a sample; the other two thermocouples are temperature control thermocouples and are used for automatically regulating the power of the heating element according to the measurement value of the temperature measuring thermocouple, so as to enable the sample in the heating furnace to accurately reach working temperature. The heating furnace is provided with a programmable temperature control system with accuracy of 0.2 class and good heat insulating performance. The structure of the heating furnace is designed to be of a bidirectional side-by-side opening type and is installed on sliding guide rails, and the heating furnace is guaranteed to be accurately positioned and be stable and unchanged for a long time. Since the novel temperature control system is adopted, the defects of low intelligent level, inconvenience in operation and the like of a traditional heating furnace are overcome; since a man-machine interaction interface is used as an input and display terminal of the system, the traditional control method of using a temperature control meter in the temperature control field is changed.

Description

technical field [0001] The invention belongs to aero-engine material performance testing technology, and relates to a plate sample fatigue test heating furnace for high-temperature stress fatigue tests of small-sized thin-walled samples (length 180mm×width 50mm×thickness 3mm). Background technique [0002] With the improvement of aero-engine performance requirements for materials, it is particularly important to obtain performance data of materials at high temperatures, especially above 1200 °C. The shortcomings of traditional products such as low intelligence, inconvenient operation, and unsatisfactory test temperature are also prominent. The overall structure design of the new small-sized thin-walled sample fatigue test heating furnace is reasonable, small and light, easy to operate, and the application of some new materials and technologies can be reflected in this equipment. The new product has fast heating speed, precise temperature and complete and reliable safety mea...
