how to choose high temperature furnace

High temperature furnace is a kind of common heating equipment manufacturers, the main for the working condition of laboratory, enterprises, scientific research units for element analysis and determination, alloy steel products, all kinds of metal parts of normalizing, quenching, annealing and other heat treatment, can also be made of metal, ceramic sintering, dissolution, analysis, diamond cutting blades for high temperature sintering and other high temperature heating, also can be used in sintering with organic matter. It belongs to electric furnace for periodic operation.

In the choice of high temperature furnace manufacturers also depends on the quality of the key, rather than the simple low price. What kind of high temperature furnace manufacturer good, what kind of electric furnace poor?

First of all, let's analyze the main components of high-temperature furnace manufacturers:

1- Insulation materials;

2- Heating element;

3 - electronics;

4 - shell;

Now that we know the main components of high-temperature furnace manufacturers, so the quality of high-temperature furnace manufacturers depends on this important part.

1- Quality of insulation materials;

2- The quality of heating elements;

3- Quality of electrical appliances;

4- The quality of the shell.

How to choose the quality of insulation material?

First of all, you need to see the temperature of the experiment, for example: the commonly used temperature of the experiment is 1000 degrees, so choose high temperature furnace manufacturers insulation material must be able to withstand high temperature to reach 1100 degrees ~1200 degrees insulation layer, namely the highest temperature of the electric furnace to be able to reach 1100 -- 1200 degrees. Only in this way can you meet the requirements of the experiment, in order to reach the longest life under normal use, there will be no abnormal conditions, so as to be most conducive to the experiment.

Quality of heating elements

The high temperature furnace manufacturer heating element, resistance wire, carbon silicon rod, silicon molybdenum rod above three kinds of heating element are determined according to the highest temperature of customer experiment, general 1000-1200 degrees for resistance wire, 1300 degrees for silicon carbon rod, of course, the higher the temperature the price is also correspondingly high.

High temperature furnace manufacturers can be divided into four grades:

1- Refractories, cost is not high, heat is limited.

2- High temperature aluminum furnace, adaptability test without carbon.

3- Silicon carbide furnace, the furnace temperature is not fast, temperature heating is better.

4- Ceramic fiber furnace, this furnace cost is high, has the advantage of high temperature, local temperature is too high, so it is easy to burn down the furnace. It is recommended to use the laboratory furnace manufacturers, choose silicon carbide furnace furnace manufacturers, no matter from which side are more safe.
