Ceramic Fibre Muffle Furnace

Ceramic Fiber Muffle furnace is specially designed and manufactured for sample pretreatment, melting test in metallurgical laboratory, annealing and quenching of heat treatment, etc. It adopts advanced manufacturing process and new environmental protection and heat preservation materials. The shell of electric furnace is made of high-quality steel, luxurious and beautiful, built-in all fiber furnace structure, made of high-purity alumina fiber material After molding, it is sintered at high temperature. Due to the high density and small heat capacity of all fiber furnace material, it has low energy consumption and high thermal efficiency, which can meet the requirements of rapid temperature rise and drop, and has the characteristics of uniform furnace temperature, good heat preservation effect, light weight, high efficiency, environmental protection and energy saving. At the same time, the temperature control system is equipped with intelligent temperature program controller, which adopts high-quality SCR module phase-shift voltage regulation control mode, automatic protection of overtemperature alarm, high temperature control accuracy, safety and reliability. It is an ideal equipment in the laboratory.

The ceramic fiber muffle furnace has the following characteristics:

1. The ceramic fiber muffle furnace has a temperature control process, which realizes the linear control of pressure rise;

2. Adaptive control technology is adopted. The instrument realizes the temperature characteristic test of muffle furnace and stores the memory. The collaborative PID control algorithm ensures that the temperature control accuracy is better than the national standard;

3. The parameters are adjusted by using the intelligent discrimination method of microcomputer to realize the active adjustment of preheating temperature and the storage of memory. No need to set the preheating temperature and time manually;

4. Display macro, display experiment process, time, temperature and performance trademark at the same time;

5. Cold rolled plate and shell, beautiful appearance, small volume, less operating buttons Z, good performance Z. Active realization of cold end compensation and open circuit detection. Cooperate with high precision A / D converter to ensure the accuracy of temperature measurement.

6. Manual control performance: immediately measure the temperature in the furnace, manually adjust the input power to achieve the performance of controlling step or completing constant temperature control;

7. The experiment process can be manually adjusted at any time.

The following points should be paid attention to in daily use of Ceramic Fiber Muffle Furnace:

1. When the muffle furnace is used to heat the workpiece, the combustion plate is not supported:

Each muffle furnace has a corresponding combustion plate size, and all heated workpieces, including the container of workpieces, should be heated at the top of the combustion plate. Try to avoid the ceramic fiberboard placed directly on the bottom of the furnace, resulting in uneven local stress of the fiberboard or high local temperature, damaging the bottom of the furnace.

2. I want the muffle to cool quickly and open the door at high temperature:

As the ceramic fiber muffle furnace has good heat preservation effect, low heat preservation energy consumption and slow temperature drop after power failure. Some customers want to carry out the next test immediately after one test, so they open the furnace door at high temperature to obtain higher cooling speed, but this kind of damage to muffle furnace is very big, once cold and hot occurs, it is easy to cause furnace cracking, heating elements can not bear this cold and hot impact. We generally recommend that you do not turn on the muffle carefully until the temperature reaches at least 600 ℃. If you really need to pick up and release parts at high temperatures, consider whether you can use a silicon carbide furnace.

3. Do not dry the furnace after a long shutdown:

This is also a detail that is easy to overlook. Basically, all customers can bake the oven for the first time. However, many customers forget to bake when they use it after more than a week. Ceramic fiberboard has a large number of small voids, such as the magazine which can absorb water vapor when it cannot be used for a long time, so the drying furnace can effectively remove the water vapor in the voids according to the requirements.

In addition, to prolong the service life of furnace wire, attention should be paid to:

a. No high temperature operation for a long time;

b. Correct preheating;

c. Properly reduce the output voltage in the process of digital display control, slow down the heating speed and select high quality.
