Operation method and precautions of automatic thermal shock resistance testing machine

Refractory materials often face drastic changes in ambient temperature during industrial production, so thermal shock resistance is particularly important for their service life and production safety. As a device for testing the thermal shock performance of refractory materials, the automatic thermal shock resistance tester can simulate the thermal cycle process of materials in high and low temperature environments and evaluate their thermal shock resistance stability. In this article, Hutt's editor mainly introduces the operation method and precautions of the automatic thermal shock resistance tester.

1. Operation method of automatic thermal shock resistance tester

Prepare and install samples

According to the test requirements, prepare refractory material samples that meet standard specifications, including raw materials or finished product specimens. The shape, size, quantity, etc. of the sample must be strictly implemented in accordance with relevant standards. Install the sample on the special bracket or fixture of the test machine as required, and pay attention to ensure that the sample is firmly fixed to avoid displacement at high temperatures.

Set test parameters and preheat the test chamber

According to the test purpose and material type, set appropriate test parameters, including high temperature end temperature, low temperature end temperature, heat transfer medium (air or other medium), number of cycles, etc. Correct parameter setting is particularly important for the accuracy of the test results. Start the heating system of the test machine, preheat the test chamber to the set high temperature end temperature, and continue for a period of time to stabilize the temperature.

Start the test cycle and monitor in real time

Start the automatic control system of the test machine to make the sample circulate heat transfer between the high temperature end and the low temperature end to simulate the thermal shock environment. At the same time, the counting machine will automatically record the number of cycles. During the test, the state changes of the sample are monitored in real time through the observation window and monitoring system. If cracks, fractures, etc. occur, they should be recorded in time.

Termination of the test and removal of samples

When the set number of cycles is reached or the sample is seriously damaged, terminate the test and turn off the heating system. After the test chamber cools down, take out the sample, mark it and package it for subsequent analysis and testing. A comprehensive analysis of the test data and sample conditions is conducted to calculate key indicators such as the thermal shock damage rate, which are compared with standard values to assess the material's thermal shock resistance level.

2. Precautions for the operation of the automatic thermal shock tester

Personnel safety: Operators must undergo professional training and be familiar with the use of the equipment and safety plans. During the high-temperature test, personal protective equipment such as heat-insulating gloves and protective glasses must be worn, and stay away from the running equipment to avoid being burned by high-temperature components.

Equipment inspection: Before each use, the equipment must be fully inspected to ensure that the heating system, cooling system, control system, etc. are in good condition and calibrated as required.

Ventilation conditions: The automatic thermal shock tester will generate a certain amount of heat and exhaust gas during operation. It is necessary to maintain good ventilation in the test room to avoid heat accumulation and harmful gas accumulation.

Maintenance: Clean, inspect and maintain the equipment regularly, and replace aging parts in time to ensure the long-term stable and energy-efficient operation of the tester.

The operation methods and precautions of the automatic thermal shock tester have been introduced to you. Only by strictly implementing relevant regulations can the role of the tester be fully utilized and provide a reliable basis for the optimization and selection of refractory materials.
