The fechral tape belongs to flat rolled products, which makes it possible to manufacture flat and flexible electric heating elements from it. They can be used in roasting and drying ovens, electric heaters or industrial electric furnaces, the maximum operating temperature of which does not exceed 1400-1450 °C. The small thickness of the blanks is used to bend the heaters and their optimal placement inside the equipment. Such elements are often used for furnaces and equipment of small power and, accordingly, small size.
Another area of application for Fechral tape is the production of resistance elements (resistors) designed to regulate the current strength.
The tape is made from grades of Fechral Kh15Yu5, Kh23Yu5, Kh23Yu5T, Kh27Yu5T, superfechral GSSY or Eurofechral GS23-5, GST. The main components of all grades of Fechral are iron (Fe), chromium (Cr), aluminum (Al).
Our company manufactures heating elements of any size and shape in accordance with the sketches of customers from all types of fechral tape.
Fechral tape is made from special grades of metals such as Kh23Yu5, Kh27Yu5T and Kh27Yu5, which provide a high degree of reliability and durability of the product. The main components of these alloys are iron, aluminum, chromium. Silicon, manganese and nickel are used for doping.
This resistive element is widely used in various industries where high temperature stability and precision are required. Fechral tape finds application in electronics, automotive industry, as well as in the production of heating elements. The thickness of the finished product can be different - from 1.0 to 3.2 mm.
Due to its unique properties, fechral tape is an indispensable material for creating electrical circuits with certain resistance characteristics. It has a high degree of stability at various temperatures and pressures, which allows it to be used in the most extreme conditions.
Fechral (kantal) is a precision iron-based alloy, consisting of the following elements: Cr (12-27%); Al (3.5–5.5%); Si (1%); Mn (0.7%); the rest is Fe.
It is a hard, brittle alloy, difficult to machine, has a high electrical resistivity of 1.2–1.3 μΩ m (1.2–1.3 Ω mm²/m). Density 7100-7300 kg/m³, melting point about 1450 °C. Maximum operating temperature 1400 °C (for Kanthal A1[1]).
Resistant to oxidation in air at high temperatures.
It is used for the manufacture of heating elements of powerful electric heating devices for industrial and technological furnaces, starting and braking resistors for electric locomotives, multiple unit rolling stock, in electronic cigarettes as a heating element.
After its first (after manufacture) heating to 350-400 ° C, it becomes brittle due to recrystallization. After heating, a wire with a diameter of 0.5-1 mm breaks easily, forming an uneven fracture.
Available in the form of wire, rods, tapes, plates.
Fechral tape and foil are produced using a rolling process. In this case, the blanks are not heated, respectively, the resulting semi-finished products are cold-rolled.
Depending on the thickness, the products are made soft or hard. Fechral tape with a thickness of 0.2 mm or more is subjected to heat treatment (annealing) and acquires a soft state; with a thickness of less than 0.2 mm, the workpieces are made solid. In some cases, the surface is etched to clean it from various contaminants that may arise as a result of rolling.
It is worth noting that fechral foil is a tape that has a small thickness, the value of which is usually 0.3 mm or less.
Product dimensions, mechanical properties, delivery status, electrical resistance, as well as maximum operating temperatures are regulated by the GOST 12766.2-90 standard.
Application
The main area of application of products is the manufacture of flat heaters. Such heaters are most often used in industrial electric furnaces, electric heaters, the maximum operating temperature in which does not exceed 1400 °C.
Another area of application for Fechral tape is the production of resistance elements (resistors) designed to regulate the current strength. They are installed in various electrical installations: starting rheostats, ballasts for cranes and others. Such resistors are present in the electrical circuit of the brake system.healthy; in electric motors, they provide a smooth start.
