8Using a computer to control the servo motor to drive the screw to rotate and translate, causing the flame gun to move forward and backward, achieving rapid heating and cooling; can

Automatically adjust the distance of the gun according to the experimental temperature to achieve automatic temperature control. Computer software can save experimental data and temperature curves.

2、 Composition and simple principle of the instrument

1The instrument consists of five parts: servo motor control system, gas cylinder and flame gun, temperature acquisition and control system, computer control, and water cooling device

Composition of components.

2Working principle: Use oxygen and acetylene to rapidly heat the sample through a flame gun. First, set the test temperature and time on the computer,

After ignition, start the test and the computer controls the movement of the flame gun. When the test temperature is reached, it will automatically keep warm. At the same time, the computer automatically records the temperature changes on the front and back of the sample.
