The demand for more efficient, rugged and low cost industrial heating equipment has led to the most exacting specifications being placed upon the materials from which such units are fabricated. To meet such requirements silicon carbide (SiC) has become of increasing usefulness because of its own peculiar physical and chemical properties. Why is Silicon Carbide So Good in Industrial Heating? 1. High Temperature Resistance Silicon carbide can be utilized in high temperature applications because of its good thermal shock resistance. For instance, it does not suffer greatly by way of size reduction or breakage at temperatures of 1500°-1600°C of the heating equipment proper. Rigid heating elements, furnaces, kilns, and other heating devices have been fabricated with silicon carbide heating elements since these parts readily withstand elevated temperatures and facilitate heating equipment working in extremely hot applications. Because of the properties of SiC at impingement temperatures of 1600°C (3000°F) or higher it does not lose shape or place, nor will it melt. 2. High Thermal Conductivity The material is resistant to thermal shock and propagates the temperature throughout the heating equipment. Being a good conductor of heat silicon carbide also aids in evenly distributing heat throughout the equipment which is an important property of this material some heating systems requiring the most uniform temperature through suitable equipment”.SiC lends itself to the requirement for keeping the heater or heating element at the correct temperature throughout the equipment, thus adding to the economy of industrial heating equipment and reducing the cost of operation.
Relative humidity sensors
Another immediate application for silicon carbide is in the manufacture of relative-humidity sensors with the capacity of quite high accuracy, which attain the present-day standard in this field. The thin-layered film of silicon carbide is deposited on a quartz microspring, and made to glow at a temperature greater than that of the surroundings, condensing moisture and recording its evaporation. A deviation from the temperature of the environment on the quartz spring is registered electrically.
Furnace Linings
As a lining for furnaces, aimed to process high-temperature materials, silicon carbide can resist impacts, is sound in itself, resists corrosion, and is in receipt of certain advantages against high-temperature degradation, and high-temperature undercutting. By this means it helps to prevent early erosion, and in addition, protects the inner lining from damaging causes.
Why use silicon carbide heating equipment?
Economy
SiC gives better performance for less power, and gives nothing away while allowing the whole heating element to work more cheaply. This green and friendly material is a low-cost means of saving money on all your business overheads.
Long lasting
Everything in a busy factory is constantly wearing out and it costs to repair and replace your heating equipment. Now you can save money with cheap mass produced silicon carbide ovens for the kilns. Their hard wearing strengths, make the SiC items a sound choice.
Supports safety
Silicon carbide heating equipment that can get too hot are more prone to failure or becoming a health and safety hazard if they overheat on site. The more reliable your machinery is, the safer your factory will be. It pays to have silicon carbide in your heating equipment for more than one reason! Manufacturers build into their designs the presence of silicon carbide for a reliable, cool operation.
In conclusion
Silicon carbide is the material par excellence in industrial heating equipment, with its high-temperature capability, thermal conductivity and wear resistance. There are many ways in which it can be employed from the manufacture of temperature sensors, and virtually every other type of quality, reliable kiln including, of course, furnace linings which are inseparable from the whole industrial process. If incorporated in your general arrangement of industrial heating equipment, it adds value by reducing up-keep and operating costs. Put Silicon Carbide in your heating and watch it go up in the world!! An increasingly desirable material, instituted in practical use for the future.
