What material electric furnace wire is not easy to burn out

Generally, the electric furnace wire should be designed to consider the power, material, temperature, and surface load power. As you said, if the uneven heating causes a short period of burnout, the material, the operating temperature and the surface load power should be considered. The solution is to redesign the resistance wire.

Electric furnace wire is a very widely used heating material, which can often be seen in home life. But ordinary people generally know very little about it. Why did the electric stove wire break suddenly? There are many reasons for the electric furnace wire to burn out, and the following will introduce a few aspects to you:

Why did the electric stove wire break suddenly? There are many reasons why the electric furnace wire burns out, and the following points are summarized:

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

2.It is possible that water leaks in the environment of the electric stove wire;

Why is the electric furnace wire easy to burn What is the principle How to connect it when it is broken.

3.After a long time, due to the local oxidation of the electric furnace wire, the resistance is unequal, resulting in the local electric furnace wire temperature is too high and melts.

4.Because in the process of drawing the electric furnace wire, the workshop master did not pay too much attention, and the electric furnace wire was unevenly pulled, and it was easy to break if it was too dense.

5.The material of the electric furnace wire is too ugly, there are many grades of iron-chromium-aluminum wire and nickel-chromium wire, for example, iron-chromium-aluminum is divided into 255,,21Al6,23Al5, these three grades are iron-chromium-aluminum are relatively common, if the furnace temperature is high, you must choose more than 21Al6NB, because these materials are temperature-resistant; If you choose nickel-chromium wire, there are several grades of nickel-chromium wire, nickel-chromium 2080 is a very good material inside, although other grades are also good, but the nickel content is lower than that of 2080, so if you do nickel-chromium electric furnace wire, it is recommended to make nickel-chromium 2080 electric furnace wire.

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

The pitch of the electric furnace wire is too large, which can easily lead to the burning of the electric furnace wire; If the outer diameter of the electric furnace wire is wound too large, it may also cause the electric furnace wire to burn easily; Or when the furnace temperature is 1000 degrees, the wire diameter is too small, and the electric furnace wire is easy to burn out.

Why is the electric furnace wire easy to burn What is the principle How to connect it when it is broken.

Why does the electric furnace wire break suddenly? First of all, we have to understand how its electric furnace wire works

The amount of heat generated by the passage of electric current through a conductor is directly proportional to the current, voltage, and resistance of the conductor itself! The specific formula is "q (heat) = i (current) squared multiplied by r (resistance) multiplied by t (time)"!Resistance wire heating is this principle!

If you want to heat something, if you heat something that is not next to the resistance wire, you can not add insulation, but pay attention to safety! For safety reasons, it is recommended to add insulating materials, such as ceramics, which have better insulation and thermal conductivity!

How to connect the electric furnace wire when it is broken? Two cases:

First of all, if the electric furnace wire is broken, the position of the electric furnace wire joint should be polished clean first, and then the copper lead wire should be wound around the joint position and wound it a few more times, so as to ensure the good contact performance of the electric furnace wire. If it is in the following electric furnace wire, then it is recommended to replace it with a new one, otherwise it can also be welded with A402 electrode.

Secondly, in the case of different voltages, the length of the electric furnace wire is different, and the length of the coil can also shorten the degree of long-term disturbance and dissipation, which is also conducive to the concentration of heat. However, the collision between the coils of the electric furnace wire is the same as that described above, and it is easy to fuse at high temperatures.

1.It is possible that the environment with the electric stove wire leaks water and rolls stupidly; 2.Poor contact at the interface of the electric furnace wire will also cause the electric furnace wire to burn easily; In addition, if the electric furnace wire has been at its limit temperature or exceeded, it will be easy to burn out.

Hello dear 1It is possible that the environment leaked with an electric stove silk car; 2.Poor contact at the interface of the electric furnace wire will also cause the electric furnace wire to burn easily; 3.

Because in the process of drawing the electric furnace wire, the workshop master did not pay too much attention to it, and the electric furnace wire was unevenly pulled, and the place that was too dense was easy to break. 4.After a long time, due to the unequal resistance caused by the local oxidation of the electric furnace wire, the manuscript caused the local electric furnace wire temperature to be too high and melted5

The material of the electric furnace wire is too ugly, there are many grades of iron-chromium-aluminum wire and nickel-chromium wire in each material, for example, iron-chromium-aluminum is divided into 255,,21Al6,23Al5, these three grades are iron-chromium-aluminum are relatively ordinary, if the furnace temperature is high, you must choose more than 21Al6NB, because these materials are high temperature resistance; If you choose nickel-chromium wire, there are several grades of nickel-chromium wire, nickel-chromium 2080 is a very good material inside, although other grades are also good, but the nickel content is lower than that of 2080, so if you do nickel-chromium electric furnace wire, it is recommended to make nickel-chromium 2080 electric furnace wire.

Summary. The quality of the electric furnace wire is not high, and the oxidation is too fast, which reduces the current resistance of a certain section of the furnace wire, so that it burns off, and the electric furnace wire is easy to burn out after poor contact after knotting the head. The best way is to replace the high-quality furnace wire, if you have to tie the knot, you can pile a small amount of broken glass powder on the joint and energize it, so that the glass powder is melted and sintered, and then cut off the power supply to cool, so that the joint can reach the state of welding, which can prolong the service life.

The heating wire is not broken, check the switch and wiring, as well as the plug wire, it is best to measure whether there is voltage at both ends of the heating wire when it is turned on.

The oven is used to keep warm, and can be widely used in various civil and public buildings such as residences, hospitals, schools, and simple mobile houses. It is mainly heated by far-infrared radiation and heat diffusion.

The external structure of the solid wood oven is made of authentic fir or logs, which is durable, waterproof, corrosion-resistant, shock-resistant, moisture-resistant, and has a woody aroma.

Electric heater heating wire.

Resistance. It is selected according to the set power, the higher the power, the smaller the total resistance.

There is an appropriate range of resistivity of the heating wire, if the resistivity is too large or too small, it is necessary to have a very short or very long, very thin or very thick heating wire, so that it is difficult to manufacture and use electric heaters of large and small powers.

An important parameter of the heating wire is the surface power. If the resistivity is too large, the surface power will be large when a certain current is introduced. Therefore, for low-power electrical appliances, small diameter and small current are selected, but the size of the current is determined by the size of the resistance, and the length and diameter of the heating wire are calculated.

The use of electric heat in large-scale industrial electric furnaces is to increase the surface area to ensure that the surface power will not exceed the standard. At the same time, in order to ensure high power, there must be a large enough current, so that the length and cross-sectional area and shape of each electric belt are comprehensively considered.

Therefore, the heating wire (belt) used in the electric heater, when designing an electric heater, it is necessary to have many factors of power.
