The Globars for the Sic heaters have specific types to serve different industrial applications. Some popular types include:
Globar I
The Globar I consists of a carbon element Globar heater and a Sic support tube. The heater generates heat by using resistance heating elements made of ceramic material for high-temperature applications. Its functional principle involves the direct passage of electrical current through the carbon rod. Globar I is widely used in high-temperature industrial furnaces, kilns, and glass-melting tanks.
Globar II
The Globar II heater also consists of two main parts: a carbon element Globar heater and a Sic support tube. However, the functional principle of the two is different. Globar II works in a similar way to Globar I. Globar II is widely used in glass-melting tanks and high-temperature industrial furnaces.
Globar III
Like Globars I and II, Globar III has a carbon heating element and a support tube made of SiC. However, Globar III works different from Globar I and Globar II. Users can choose Globar III whenever they can't use Globar I or Globar II. Globar III is widely used in high-temperature and low-oxygen industrial environments. The environments are such that Globar I and II cannot be applied.
Globar Group A
The carbon element of the Group A globar heaters is a rod with a resistance of 21.5 ohms per foot. This resistance generates heat energy and serves power needs in different applications. Group A globars are ideal globar heaters for general applications.
Globar Group B
Group B globar heaters consist of a rod with a resistance of 56 ohms per foot. The higher resistance of Group B globars makes them suitable for applications that require a higher power density. Users can also consider them for use in more demanding applications that require more energy output.
Material Composition:
SIC globar rods are made of silicon carbide, a compound created by combining silicon and carbon. This unique makeup gives them strong resistance to heat and the ability to last a long time.
Diameter Range:
SIC Globar rods come in various thicknesses, measured as diameters. They can be as thin as a pencil to thicker than a finger. The width chosen matches the furnace size and heating requirements.
Length Options:
The length of Globar rods varies too. Short ones may only be several inches long, while longer ones can reach several feet. As with diameter, furnaces and heating needs determine what length is used.
Power Rating:
Each SIC Globar rod has a specific power rating, which shows how much electricity it can safely handle during operation. This rating also depends on furnace type and heating demands.
Regular Inspection:
Scheduled maintenance should include routine visual inspection of the Globar SiC elements. The focus should be on checking for any irregularities like cracks, breaks, or deformations. Prompt detection of even minor damage can prevent further escalation of issues, ensuring the continued smooth operation of the equipment.
Cleaning:
Proper cleaning of Globar SiC components is equally important for their longevity. Users should avoid the use of abrasive substances or overly forceful cleaning methods as these can inflict damage upon the elements. Instead, they are advised to employ soft wipes or cloths along with mild detergents. This approach will assist in removing dirt deposits that accumulate during regular use while simultaneously safeguarding against potential harm to the delicate surfaces of the components.
Pay attention to the working environment:
For the sustained effective functioning of Globar SiC rods, it is vital that attention be given to the conditions surrounding these items during usage. High humidity levels and places where there exists the possibility of getting in contact with corrosive substances should be avoided. Such chemicals pose a threat by potentially inducing deterioration or damaging reactions directed at the SiC material. Hence, maintaining appropriate atmospheric circumstances free from any aggressive agents will prolong the service life of such equipment considerably.
Ceramic industry:
Globar SiC elements are utilized in the ceramic industry to assist with the drying, melting, and firing of ceramic products like pottery, porcelain, and tiles. Because of their resistance to oxygen and chemical reactions, they are the best candidate for use in high-tech ceramics.
Chemical industry:
In the chemical industry, Globar Sic elements serve as catalysts in chemical reactions, increasing the reaction's speed while lowering the process's energy requirement. For instance, they can support reaction furnaces or polymerization reactors.
Glass industry:
GloBar SiC elements play a role in the glass industry by providing the high temperatures needed for glass melting, shaping, and annealing. They are also employed in the production of special glasses like quartz and optical glasses.
Metallurgical industry:
GloBar SiC elements are used for metal heating, smelting, and alloying in the metallurgical industry. They can generate and sustain high-temperature environments that are necessary for the production of various metals and alloys.
Food processing:
Sic globar elements can be used in the food processing field for food drying, sterilization, and cooking. They can supply a constant heat source to ensure food safety and improve the shelf life of food products.
Textile industry:
Sic globar elements are applied in the textile industry for fabric drying, finishing, and treatment processes. They are used to provide the required heat for the fixation and chemical processing of textiles to enhance the quality and performance of textile products.
Environmental industry:
In the environmental sector, Globar Sic elements are used for waste incineration, flue gas treatment, and purification processes. They help protect the environment by lowering waste disposal's carbon footprint and promoting clean air.
Aerospace industry:
In the aerospace sector, Globar SiC elements are utilized to manufacture aerospace components like heat shields, turbine blades, and rocket nozzles. Their capacity to withstand high temperatures and thermal shock resistance support the aerospace industry's high-performance applications.
Need analysis of current equipment:
The wattage, voltage, and type of loads that must be addressed by the new Sic Globar element must all be determined by conducting a thorough analysis of the present apparatus. This ensures that the new element can adequately meet the heating requirements of the system it will be a part of.
Specification matching:
Focus on matching the ratings and characteristics of the Sic Globar element being considered with those of the existing equipment to guarantee compatibility between them. A successful partnership between both components depends on this close alignment.
Supplier selection:
When choosing a Sic Globar supplier, it's important to carefully evaluate the selected supplier's reputation and technological advancement. Make sure to choose a supplier that has a proven track record of dependable service and high-quality products as well as pioneering technologies in order to receive optimal solutions for your needs from them.
Testing and validation:
After installation, confirm the performance of the Sic Globar element is as anticipated and examine its functioning to make sure it is operating correctly as intended while providing the expected level of performance throughout its use instance.
Q1: What is the purpose of a SIC heating element?
A1: The purpose of the SIC heating element is to produce heat to high temperatures in high-temperature applications.
Q2: How long does a globar element last?
A2: Globars typically last somewhere between two to five years, depending upon usage, operating temperature, and other factors.
Q3: Do globar rods glow?
A3: Globars do not glow like white hot elements. Under normal operating conditions, they appear dull red or dark red to infrared observers.
Q4: Are Globars conductive or radiant?
A4: Inner-source conductive and radiative outer sinks are the latter re-globars. There is no direct radiation between outer sink and inner source. Heat conductively passes through the ceramic insulated Substantial radiation occurs between inner and outer sinks.
