Structure and characteristics of high temperature flexural testing machine

High temperature flexural test machine is a special equipment used to test the bending resistance of refractory materials, ceramics, concrete and other materials under high temperature conditions. By evaluating and testing the high temperature flexural resistance of the product, the safety performance of the material in a hot working environment is ensured. In this article, the editor of Hut Instrument mainly introduces the structure and characteristics of the high temperature flexural test machine.

1. Structure of high temperature flexural test machine

Heating system

The heating system of the high temperature flexural test machine is one of its core components, usually in the form of a resistance furnace or an induction heating furnace. The heating system can heat the sample to a specified high temperature according to the test requirements, and the temperature can be accurately controlled and kept stable for a long time. At the same time, the thermal field inside the heating chamber is evenly distributed to avoid excessive temperature gradients of the sample.

Test table

The test table is usually made of high temperature resistant and corrosion resistant metal materials, and is treated with special processes to ensure that it still has good strength and rigidity in a high temperature environment. A device that can adjust the support position of the sample is provided on the table to fix the position and support form of the sample.

Loading system

The loading system is the key component for applying the test force. It is usually driven by hydraulic or screw drive, which can accurately control the loading rate and loading force. The loading system is connected to the test table and transmits the force to the specimen through the pressure head.

Data acquisition and control system

Modern high temperature flexural testing machines are equipped with computer control systems for real-time monitoring and recording of various parameters during the test, such as temperature, displacement, stress, strain, etc., and can automatically control the heating and loading process according to the preset program. Data acquisition is accurate and reliable, providing a basis for subsequent data analysis.
