1700 ℃ quartz glass melting furnace
SPK-PL1700-17LTI series 1700 ℃ high temperature vacuum atmosphere furnace is shown in the figure, which integrates the control system and furnace. The furnace lining is vacuum formed multi-layer high-purity alumina, and the silicon molybdenum rod is used as the heating element to ensure the uniformity of furnace temperature.
major function
Use silicon molybdenum rod as heating element; It is a special equipment specially developed for the laboratories of colleges and universities, scientific research institutes and industrial and mining enterprises to sinter, melt, analyze and produce ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractories, new material development, special materials, building materials, metals, nonmetals and other chemical and physical materials.
The control panel is equipped with intelligent full touch screen intelligent temperature regulator to control the power switch at any time, so as to observe the working state of the system at any time and control the power in real time. This product adopts reliable integrated circuit, with good working environment and anti-interference. The shell temperature of furnace body at the highest temperature is ≤45 ℃ greatly improves the working environment. Microcomputer program control, programmable curve, fully automatic temperature rise / drop, temperature control parameters and programs can be modified during operation, which is flexible, convenient and simple to operate.
Temperature control accuracy: ± 1 ℃ without overshoot Constant temperature accuracy: ± 1 ℃, furnace temperature uniformity: ± 3 ℃. The heating rate is fast, and the fastest heating rate is ≤ 10 ℃ / min. Intelligent full touch-screen temperature controller is adopted, and apid adjustment mode is adjusted by artificial intelligence. It has self-tuning and self-learning functions, excellent control characteristics without overshoot and undershoot, pre stored 10 groups and 30 sections of program control function, which can realize the rise and fall temperature control of any slope, programmable / operable commands such as jump (cycle), operation, pause and stop, and allows the program to be modified at any time during the control operation of the program; Using the artificial intelligence adjustment algorithm with curve fitting function, the smooth curve control effect can be obtained.
All furnace materials are vacuum formed high-purity alumina light gathering materials, with high operating temperature, small heat storage capacity, rapid heat and cold resistance, no crack, no slag falling and good thermal insulation performance (the energy-saving effect is more than 60% of that of the old electric furnace). Reasonable structure, inner and outer double-layer furnace sleeves, air cooling and heat dissipation, which can greatly shorten the test cycle.
The integrated modular control unit is adopted with accurate control accuracy, and the double loop control and double loop protection are designed, which have the protection of overshoot, overshoot, undershoot, segment couple, lack of phase, overpressure, overcurrent, overtemperature, current feedback, soft start and so on.
The electric furnace body adopts the air-cooled double-layer furnace body structure, and the effective air-cooled guide diaphragm makes the overall cold air circulation of the furnace shell. Finally, after cooling the conductive sheet of the heating element, it is discharged from the furnace body, avoiding the high-temperature oxidation of the conductive sheet of the heating element; Ensure a good working environment.
