Overview
SX2-8-10N integrated box type resistance furnace (muffle furnace) is a periodic operation heater, which can be used for sintering, heating and heat treatment operations in coal, electric power, chemical industry, building materials, metallurgy, scientific research and other units as well as Universities & colleges laboratories. It is especially suitable for coal quality analysis tests. It is widely used in coal ash and volatile matter determination, coal ash composition analysis, ash melting point and ash viscosity sample preparation and other burning operations.
Features
1. Using domestic professional technology, the furnace shell adopts high-quality cold plate after phosphoric acid film salt treatment, high temperature spray, Appearance is beautiful
2. Integrated design of control box and furnace body to avoid cumbersome installation
3. The inner lining is a rectangular integral lining made of high aluminum and silicon carbide refractory materials
4. The iron-nickel-chromium-aluminum alloy wire spiral heating element passes through the four walls of the furnace lining and is evenly heated up, down, left, right and right
5. Sealing furnace structure, using refractory fiber aluminum silicate cotton, diatomaceous earth products insulation layer, uniform temperature in the furnace
6. PID adjustment control system, display accuracy 1 ℃
7. Built-in secondary over-temperature protection device, over-temperature alarm and disconnection
8. Full range programmable setting, 30 program settings, automatic control of temperature rise thermostatic
Principle
The resistance furnace is electrified and heated through the resistance wire of iron-nickel-chromium-aluminum alloy, and the heat is evenly transferred to the furnace through the four walls of the furnace. The PID adjustment control system is adopted, and the temperature in the furnace is monitored in real time through the K-indexing nickel-chromium-nickel-silicon Thermocouple, and the heating power is precisely controlled with solid state relays to realize automatic heating and thermostatic control. Built-in secondary overtemperature protection device ensures the safe operation of the equipment.
Applications
Coal, electric power, chemical industry, building materials, metallurgy, R & D institutions, Universities & colleges laboratories, coal quality analysis test, ash determination, volatile matter determination, coal ash composition analysis, ash melting point sample preparation, ash viscosity sample preparation
Steps
1. Connect the 380V power supply
2. Set the temperature program through the controller (up to 30 segments)
3. Set the timing time (0-9999 minutes)
4. Start the device to start heating
5. Equipment automatically controls the thermostatic process
6. Turn off the power after finishing heating
Notice
• The maximum operating temperature of the equipment is 1000 ° C
