Iron-chromium wire

Iron-chromium wire is divided into four grades according to the maximum use temperature: ultra-high temperature grade iron-chromium wire, high temperature grade iron-chromium wire, medium temperature grade iron-chromium wire, and low temperature grade iron-chromium wire.

Ultra-high temperature grade iron-chromium wire: this group of series of iron-chromium wire contains high chromium and aluminum, but also contains a certain amount of cobalt, molybdenum, niobium, titanium and trace yttrium, cerium, lanthanum and other elements, mainly used in single crystal diffusion furnace, powder metallurgy products sintering furnace, ceramic calcination furnace and high-temperature heat treatment furnace, etc.;

High-temperature iron-chromium wire: this group of series of iron-chromium wire content is slightly lower than the ultra-high-temperature grade iron-chromium wire, also contains a small amount of molybdenum, niobium, cobalt, titanium and rare earth elements, mainly used in the manufacture of quenching, normalizing, annealing, solution treatment and other heat treatment furnaces and copper, aluminum alloy melting furnace;

Medium temperature grade iron-chromium wire: this group of series of iron-chromium wire has good plasticity, at room temperature can be processed into a variety of complex-shaped components, mainly used in tempering furnaces, aluminum melting furnace and household appliances, etc.;

Low-temperature iron-chromium wire: This series of iron-chromium wire is mainly used in the manufacture of heating furnaces with working temperature below 750℃, such as low-temperature tempering furnaces, drying furnaces and household appliances, etc.

The plant produces a variety of iron-chromium wire, electric tapes with high purity, low impurities, stable resistivity, good surface oxidation resistance, corrosion resistance, high temperature strength and better processing performance and weldability, the product can be directly processed into spiral, corrugated, Z-shaped, vertical winding belt type, steel specifications are complete.

Supply state: oxidation color or bright soft state supply;

Notes on the installation of iron-chromium wire:

1. Choose the correct wire diameter according to the reasonable surface load when designing the iron-chromium wire;

2. The furnace chamber should be thoroughly inspected before the installation of the iron-chromium wire to remove ferrite and carbonization to avoid short circuit or wire breakdown;

3. The iron-chromium wire should be properly connected according to the designed wiring method during installation;

4. Check the sensitivity of the temperature control system before using the iron-chromium wire to prevent temperature control failure, resulting in iron-chromium wire burnout.

Iron-chromium-aluminum fine wire

Soft state treatment, with good plasticity and toughness, complete steel specifications, high product purity, low impurities, stable resistivity, good surface oxidation resistance, and high temperature strength. Widely used in industrial electric furnace, metallurgy, machinery, electrical appliances, aircraft, automobile manufacturing, military and other industries to make heating elements and resistance elements.

255 iron-chromium wire

255FeCr wire temperature.

255FeCr wire specifications.
0.1-10.0mm, by automatic winding machine winding molding, according to the chart can be wound into 1kw - 160kw electric furnace bar, there are straight bars, there are double-arranged, three-arranged, up to 20 arrangements, can also be acid-washed into white, mainly for export. It should be noted that: if the spiral outer diameter and wire diameter ratio is too large, the spiral to string high-temperature porcelain tube inside to prevent collapse, resulting in accidents, workers in the installation process to do lightly, otherwise it is easy to fall off.

255FeCr wire product characteristics
High temperature resistance, fast temperature rise, long service life, stable resistance, small power deviation, uniform pitch after stretching, bright and clean surface, widely used in large and small industrial furnaces, heating and air conditioning equipment, various types of ovens, electric heating tubes and household appliances. We can design and produce various non-standard industrial and civil furnace strips according to the needs of customers.

HRE resistance tape, hre material characteristics and advantages of the introduction

Resistance band material

HRE, 0Cr27Al7Mo2, 0Cr21Al6Nb,0Cr25Al5, temperature: 1450-1250 degrees, materials are in accordance with GB/T1234-95, wire diameter: 1.0-10.0mm, by automatic winding machine winding molding, can be wound into 1kw-160kw electric furnace bar, there are straight bars, there are double-arranged, three-arranged, up to 20 The rows can also be acid-washed into white, mainly for export. Today, Zhengxing will introduce the HRE resistance strip to you.

Features of HRE resistance bands

High temperature resistance, fast temperature rise, long service life, stable resistance, small power deviation, uniform pitch after stretching, bright and clean surface, widely used in large and small industrial furnaces, heating and air conditioning equipment, various types of ovens, electric heating tubes and household appliances. Resistance band can be designed and produced according to the needs of users, a variety of non-standard industrial and civil furnace strip.

Advantages of HRE resistance bands:

HRE resistance band with high temperature

HRE resistance band belongs to iron-chromium-aluminum electric heating alloy, of which the maximum use temperature of HRE alloy can reach 1400℃, while the maximum use temperature of Cr20Ni80 alloy in nickel-chromium electric heating alloy is 1200℃. Therefore, HRE resistance band is used at high temperature.

High surface load of HRE resistance band

Since the iron-chromium-aluminum alloy allows high operating temperature and long service life, the surface load of the element can also be higher, which not only makes the temperature rise faster but also saves the alloy material.

Long service life

At the same high operating temperature in the atmosphere, the life time of Fe-Cr-Al components can be 2-4 times that of Ni-Cr components.

Low specific gravity

The specific gravity of Fe-Cr-Al alloy is lower than that of Ni-Cr alloy, which means that Fe-Cr-Al is less material intensive than Ni-Cr in making the same components.

Good resistance to oxidation

The Al2O3 oxide film generated on the surface of FeCr-Al alloy has a dense structure and good adhesion to the substrate, so it is not easy to scatter back to the flowers and water and cause? pollution. In addition, Al2O3 has high resistivity and high melting point, these factors determine that Al2O3 oxide film has excellent oxidation resistance. Carburization resistance is also better than that of Cr2O3 generated on the surface of NiCr alloy.

High resistivity of HRE resistance band

The resistivity of Fe-Cr-Al alloy is higher than that of Ni-Cr alloy, which allows the use of larger size of alloy material when designing the components, which helps to extend the service life of the components, especially important for fine alloy wire.

HRE resistance tape is cheap

Iron-chromium aluminum is much cheaper than nickel-chromium because it does not contain the more scarce nickel.

HRE resistive tape has good resistance to sulfur

For the sulfur-containing atmosphere and surface contaminated by sulfur-containing substances, iron-chromium aluminum has good corrosion resistance, while nickel-chromium will be severely eroded.
