Overview
BOZHEN BZ-5-12 integrated box type resistance furnace adopts overall design and humanized menu design, integrated industrial PID self-tuning control technology, equipped with LCD high luminance and wide window digital display, clear and intuitive indication. With boot timing or thermostatic start Timing function after setting temperature, microcomputer intelligent control can effectively solve the problem of temperature overshoot, and the temperature control is accurate and stable. Sound and light alarm and automatically cut off the heating output when the fault occurs.
Features
1. Using domestic professional technology, the furnace shell is made of good steel plate folding welding and drawing, and the control box and the furnace body are integrated in structure, with beautiful appearance and easy installation.
2. The inner lining is a rectangular overall lining made of high aluminum and silicon carbide refractory materials, and the heating element is a helical structure wound with iron-nickel-chromium-aluminum alloy wire, and the upper and lower left and right 4-sided heating.
3. The furnace is a sealing structure, and between the furnace and the furnace shell, refractory fiber aluminum silicate cotton and diatomaceous earth products are used to build the insulation layer.
4. Furnace shell with good cold plate by phosphoric acid film salt treatment after high temperature spray, Color for computer gray; Furnace liner with high aluminum, good wear resistance.
5. The thermal insulation method adopts thermal insulation bricks and thermal insulation cotton. The temperature measurement port is located above the back of the furnace body, and the terminal is located below the back of the furnace body.
6. The controller is built under the furnace body, the compensation wire is connected to the furnace body, and the heating element is nickel-chrome wire.
7. Temperature Control system adopts K-indexed nickel-chromium-nickel-silicon Thermocouple, PID adjustment display accuracy 1 ℃, complete sets of electrical appliances use brand contactors, cooling fans and solid state relays.
8. Working time can be set, thermostatic time reaches automatic shutdown, built-in two-level over-temperature protection device, over-temperature alarm and cut off.
9. The operation mode is full-scale adjustable thermostatic, constant operation.
Principle
After the resistance furnace sets the temperature through the microcomputer intelligent Control system, the instrument controls the heating output by itself. Industrial PID self-tuning control technology is adopted to ensure accurate and stable temperature control and avoid temperature overshoot. The heating element is nickel-chrome wire, which is worn through the wire grooves on the upper, lower, left and right of the inner furnace lining to achieve up, down, left and right 4-sided heating. The sealing structure in the furnace is matched with the insulation layer to effectively keep the temperature constant.
Applications
Material heat treatment, laboratory high temperature experiment, industrial heating treatment
Steps
Connect the power supply and ensure that the voltage is 220V 50Hz.
2. Set the required temperature and Working time through the controller.
3. Start the equipment, the instrument automatically controls the heating output, and starts to heat up.
4. After reaching the set temperature, the thermostatic timer starts, and the device automatically maintains the temperature.
5. After the thermostatic time arrives, the device automatically stops.
6. After use, disconnect the power supply.
Notice
- Power supply voltage meets 220V 50Hz requirements to avoid overload.
When the equipment is running, pay attention to the over-temperature protection function, and check in time if an alarm occurs.
- The furnace body is at high temperature, and protective equipment should be worn during operation to avoid burns.
- Regularly check the Thermocouple and heating elements to ensure that the connection is firm.
- Device weight is about 80KG, use appropriate tools when handling to prevent dumping.
- Keep the furnace clean to avoid foreign matter affecting the heating effect.
- When the equipment fails, the heating output is automatically cut off, and the cause needs to be checked before use.
