Overview
BOZHEN BZH-5-12TC Pottery and porcelain fiber ash determination muffle furnace is a box type resistance furnace made of good raw materials, imported core components and professional technology, and the technical indicators have reached the international professional level. The furnace adopts high temperature refractory fiber vacuum forming tank, mechatronics design, program control, digital display, energy saving rate of 40%, and meets the national C-level furnace standard, suitable for scientific research, teaching, heat treatment, melting, sintering, ashing and coal ash fusion determination in laboratories of industrial and mining enterprises.
Features
1, double-decked furnace shell, hollow insulation, strong ventilated, to ensure that the shell is not hot.
2. The furnace door is designed to open on the left, making it easy to operate.
3. Pottery and porcelain fibers are used in the furnace. The heating elements are heated on multiple sides, the temperature distribution in the cavity is uniform, the heating is fast, the energy saving is significant, and the work efficiency is high.
4, the heating element selection of good wire, stable performance, reliable, long life.
5, electrical control part of all original parts, reliable performance.
6, can make up the temperature control program, according to the experimental requirements to set their own rise, thermostatic process.
7, the use of K-type Thermocouple, sensitive response, high temperature control accuracy, good temperature resistance.
8. Equipped with a flue gas and harmful gas exhaust device for ash experiments.
9. Equipped with nitrogen filling device, nitrogen can be filled at high temperature to slow down the oxidation of the test product.
10. Equipped with over-current, over-voltage, Thermocouple failure, over-temperature protection, and other safety measures.
Principle
As a box type resistance furnace, the muffle furnace generates heat through the heating element of the wirecoil for heater. Pottery and porcelain fiber furnace has excellent thermal insulation performance and multi-sided heating method, so that the temperature in the furnace cavity rises rapidly and evenly. PID temperature control instrument and K-type Thermocouple are used for precise temperature detection and feedback control to realize the programmed heating and thermostatic process.
Applications
Laboratory in scientific research, teaching, industrial and mining enterprises for heat treatment, melting, sintering, ashing, and determination of the fusibility of coal ash
Standards
National C-class furnace standard
Steps
Connect the power supply to ensure that the voltage is 220V 50/60Hz.
2. Open the furnace door and put the sample into the furnace.
3. Close the furnace door and set the required heating program and target temperature through the temperature control instrument (Temperature range 100~ 1200 ℃).
4. Start heating, and the furnace body starts to heat up according to the set program.
5. During the experiment, if atmosphere protection is required, a nitrogen-filled device can be activated.
6. After the experiment, wait until the furnace temperature drops to a safe range before opening the furnace door to remove the sample.
7. Turn off the power.
Notice
Equipment should be used in a well-ventilated environment.
• Please pay attention to high temperature during operation to avoid burns.
• The shell temperature may rise when the furnace body is working, but the double-decked thermal insulation design ensures that it is not hot, so it is still necessary to pay attention.
• Protective Gloves should be worn when taking samples.
• When conducting ash experiments, ensure that the flue device is connected normally to discharge flue gas.
• When filling with nitrogen, check the sealing of the gas path.
• Pay attention to the power requirements on the nameplate of the equipment and do not use it under overpressure.
• Regularly check the working status of components such as Thermocouple.
• The device has multiple built-in safety protections, but it still needs to be operated according to procedures to prevent accidents.
