Categories Related to Cast Heaters
Cast heaters are used to heat metal surfaces evenly and efficiently.
Sheathed heaters, air-cooled tubes, etc., are cast into brass, aluminum, iron, etc. The heat is generated by the conduction heat when it comes in contact with the object to be heated. They have excellent resistance to overuse, shock, and vibration.
Various shapes are available, and by casting air- and water-cooled tubes, temperature control for rapid and slow cooling is possible. Rapid heating is also possible by attaching heat-dissipating fins to the outer surface.
This type of heater is suitable for use in synthetic fibers and engineering plastics, etc., where a highly precise temperature distribution is required.
Because of their high corrosion resistance and uniform temperature distribution, cast heaters are used in a wide range of applications.
They are used in home appliances such as ovens, ranges, irons, electric pots, hot plates, and electric kettles.
As commercial equipment, they are used in ovens, electric furnaces, casting parts, presses, air conditioning/heating units, kitchen equipment, electric kilns, etc.
As industrial equipment, they are used for tank heating, chemical heating, heat insulation, low-melting-point metal melting, extrusion molding machines, valve/pipe heat insulation, heating, etc.
Since a sheath heater is built into the casting, heating with uniform temperature distribution can be achieved.
Although less efficient than heating an object directly, it can be easily managed since there is no need to drain the liquid for maintenance, etc.
It is used as an indirect heating method when the space inside the tank or tanks is to be effectively utilized, or when a direct heat source cannot be installed as a countermeasure against ignition or odor.
The surface where the heater is mounted is machined to enhance heat conduction.
Sheathed heaters cast into aluminum can be processed into a variety of shapes.
Heater elements can be replaced when sheath heaters are inserted into grooves machined into aluminum plates. SUS and Bs can be used for the plate material.
Cartridge heaters inserted into the holes in the aluminum plate can be replaced with the plate attached. Arbitrary temperature distribution can be set by changing the heater power and arrangement.
