Causes of Burning of Electric Furnace Wire

Causes of Burning of Electric Furnace Wire

There are many reasons for the burning of the electric furnace wire. Today we will introduce a few aspects to you:

1. There may be water leakage in the environment of the electric stove wire;

2. Poor contact at the interface of the electric stove wire will also cause the electric stove wire to burn easily;

3. Because in the process of drawing the electric furnace wire, the workshop master did not pay much attention, the electric furnace wire is drawn unevenly, and it is easy to break when the electric furnace wire is too dense.

4. After a long period of time, due to the unequal resistance caused by the local oxidation of the electric furnace wire, the temperature of the local electric furnace wire is too high and melted.

5. The material of the electric furnace wire is too ugly. Each of the iron-chromium-aluminum wire and the nickel-chromium wire has many grades. For example, the iron-chromium-aluminum is divided into 255, 21AL6, 23AL5, and these three grades are iron chromium Aluminum is relatively common. If the furnace temperature is high, you must use 21AL6NB or higher, because these materials have high temperature resistance; if you use nickel-chromium wire, there are several grades of nickel-chromium wire, and nickel-chromium 2080 is a very good material inside. Although other grades are also good, the content of nickel is lower than that of 2080, so if you make nickel-chromium electric stove wire, it is recommended to make nickel-chromium 2080 electric stove wire.

6. The design parameters of the electric furnace wire are unreasonable:

If the pitch of the electric stove wire is too large, it is easy to cause the electric stove wire to burn out; if the outer diameter of the electric stove wire is wound too large, it may also cause the electric stove wire to burn out easily; or when the furnace temperature is 1000 degrees, the wire diameter is selected too small, the electric stove The wire is also easy to burn.
