3.1 One furnace can be used for multiple purposes and can be compatible with multiple standards.

3.2 Adopt high-precision acquisition card to collect data of various aspects such as temperature, pressure and flow rate of each road, and analyze, process and control by microcomputer to produce real-time reproduction of real information at the time of combustion, and directly derive results by microcomputer analysis and determination; the whole machine adopts all high-quality devices to ensure the system is of high quality, high speed operation and advanced.

3.3 Adopt high-precision acquisition card + multi-circuit module + PLC + computer, and implement PID automatic control mode, with excellent stability, repeatability and reproducibility.

3.4 Adopting WINDOWS XP operation interface and LabView, a special development software for global precision equipment, the interface style is fresh, beautiful and simple. During the test, the measurement results are displayed in real time and the perfect curve is drawn dynamically, and the data can be saved, read and printed out permanently. With high intelligence, guided menu operation, easy and intuitive features, so that the test results are more accurate.

3.5 The design life of the furnace is more than 15 years, and the furnace is built with American GOVMARK (Gomak) technology. Five-layer structure, when the inner layer temperature 1300 ℃, the outer layer temperature is room temperature; long service life, the insulation material of the inner layer (wearing parts) is easy to replace.

3.6 Multiple safety protection systems including air duct thermal protection, pressure release protection, leakage protection, gas leak detection, gas line safety protection, burner safety protection and other safety facilities to enhance the safety factor in all aspects.

3.7 The high temperature hot air extracted from the furnace is water-cooled and air-cooled, and the water uses circulating water, which improves energy conservation.

IV. Vertical Furnace Structural engineering design of the furnace

4.1 Furnace construction: The furnace is designed to last for more than 15 years, and the furnace is built using GOVMARK (Gomak) technology from the USA. Five-layer structure, when the inner layer is 1300°C, the temperature of the outer layer is room temperature; long service life, the insulation material (wearing parts) of the inner layer is easy to replace. The five-layer structure, from outside to inside, is as follows: the first layer is a steel frame; the second layer is built with red bricks as a periphery; the third layer is refractory high-temperature asbestos; the fourth layer is refractory bricks; the fifth layer contains zirconium refractory high-temperature cotton, with a refractory temperature of 1600°C.
