Overview

Hangzhou box type resistance furnace (quenching heat treatment) is a universal heating equipment. According to their appearance, they can be divided into box furnaces, tube furnaces, crucible furnaces, etc. Muffle furnace is translated from English as Muffle furnace. Muffle means package, furnace means stove, and melting pot means furnace. The common names for muffle furnaces in China are as follows: electric furnace, resistance furnace, Maofu furnace, and muffle furnace. Muffle furnace is generally a high-temperature furnace provided for laboratories, with different names. The products referred to are of the same category and are collectively referred to.

Product Details

The furnace structure of Hangzhou box type resistance furnace (quenching heat treatment) high-temperature resistance furnace

The control system of the high-temperature electric furnace adopts a modular structure, with key components designed for long service life, high temperature control accuracy, and stable reliability. The furnace structure includes:

furnace body

The frame is made of welded channel steel and angle steel, and the outer shell side plate is welded with Q235 steel plate. The structure is firm and reliable, with reinforced angle steel coils and channel steel base. The overall strength is good, not easily deformed, and the surface is smooth and clean.

lining

Adopting a full fiber composite structure, high-quality zirconia fiber cotton is used to make modules, and a certain amount of expansion is left during the processing to ensure that each ceramic fiber block expands in different directions after masonry is completed, so that the modules are squeezed into a seamless whole, achieving a good heat storage effect.

control system

Using temperature control thermocouples, the temperature controller can control according to the set temperature and display both theoretical and measured values. The temperature control system also has an over temperature sound and light alarm function.

Furnace cover and furnace cover lifting device

The furnace cover frame is made of welded channel steel and angle steel, and the outer shell side plate is welded with Q235 steel plate. The structure is firm and reliable, and the angle steel coil is reinforced. The furnace cover lifting device adopts electric lifting.

heating element

Adopting an advanced hanging structure, it has high radiation efficiency, strengthened heat exchange inside the furnace, improved the thermal efficiency of the furnace, and extended the service life of the electric heating element.

The correct operation process of high-temperature box type resistance furnace

The specific process operation of the box type resistance furnace is as follows:

1. Check the "shift handover record" before starting work.

2. Operators should wear the prescribed protective equipment and be familiar with the "safety operating procedures".

3. Check the lubrication condition of the axle and slide rail of the furnace door opening mechanism.

4. Check the installation and fastening of the furnace lining, resistance wire, and thermocouple lead out rod, and verify if the instruments are functioning properly.

5. Check that the resistance wires at the bottom of the furnace, the bottom plate of the furnace, the transmission mechanism of the movable furnace bottom, and the motor lead wires are in good condition.

6. Check the cleanliness of the furnace and clean the oxide scale.

7. Newly repaired furnaces should be dried according to the "process specifications".

8. Cut off the power and proceed with the baking process according to the "process specifications".

9. Close the door of the box type resistance furnace.

10. Insulate according to the "process regulations".

11. Power on heating.

12. Cut off the power after work.

13. Produce the furnace according to the "process specifications".

14. Reinstall the furnace and repeat the above procedure.

When the box type resistance furnace is operated continuously, the "handover record" must be carefully filled out, and the handover must be clearly handed over to the successor in person.

16. Maintain and upkeep the equipment according to the "Equipment Maintenance Regulations".
