What are the types of electric furnace wires?

It mainly includes two categories: iron complex aluminum alloy electric furnace wire and nickel complex alloy electric furnace wire. The former belongs to alloy materials with ferrite structure, while the latter belongs to alloy materials with austenite structure. In addition, there are some special purpose electric heating alloy wires such as tungsten wires, molybdenum wires, etc.

The characteristics of nickel complex alloy electric furnace wire are:

① High strength at high temperatures;

② After long-term use and further cooling, the material will not become brittle;

③ The radiation rate of fully oxidized nickel alloy is higher than that of iron chromium aluminum alloy;

④ Non magnetic;

⑤ Besides sulfur atmosphere, it has good corrosion resistance.

The characteristics of iron chromium aluminum electric furnace wire are:

① High usage temperature, such as the maximum usage temperature of HRE iron chromium aluminum alloy wire in the atmosphere can reach 1400 ℃;

② Long service life;

③ The allowable surface load is high;

④ Good antioxidant performance, and the AI2O3 film formed after oxidation has good chemical resistance and high resistivity;

⑤ Specific gravity less than nickel chromium alloy;

⑥ High resistivity;

⑦ Good sulfur resistance;

⑧ The price is significantly lower than nickel chromium alloy;

⑨ The disadvantage is that as the temperature increases, it exhibits plasticity and low strength at high temperatures.

Electric water heaters have gradually gained the favor of many consumers due to their lightweight, fast, and convenient characteristics. However, the safety and after-sales service issues of electric water heaters also need to be given sufficient attention. To better prevent unexpected situations, we remind consumers to pay attention to the following points when purchasing and using electric water heaters.

1、 Consumers must consider the brand and after-sales service level of electric water heaters when choosing brand services. Famous brand products generally have good quality and after-sales service, and can enjoy a series of services such as on-site installation and relocation.

2、 Although the electric water heater is equipped with a power outage protection device before use, for safety reasons, it is best to cut off the power supply (i.e. unplug the plug) before use to prevent personal injury caused by electric shock.

3、 The material of the inner liner is the core component of every electric water heater product. If the quality is not qualified, it may cause perforation due to rust or scaling, leading to water leakage, leakage, or bursting due to insufficient pressure on the inner liner material.

4、 Regularly inspect and clean the electric water heater, as there are more or less impurities in the water. After using the heating element for a period of time, it is easy to be corroded by alkaline substances in the water, which can also cause leakage of the water heater.

If consumers achieve the above points, the safety factor of using electric water heaters will also be greatly improved.

Finally, it is reminded that consumers who want to purchase electric hot water should not buy unknown brands just because they are greedy for cheap. Consumers who have already purchased electric water heaters must also pay attention to regularly inspecting and cleaning the water heaters, and promptly report and handle any problems that arise. Only in this way can consumers take a comfortable bath with peace of mind!
