Heat Treatment Controllers

ICE STAR manufactures fully digital heat precise and reliable treatment controllers. The ICE STAR controllers ISQ and ISC have from 6 to 12 controlling thermocouple's and up to 36 monitoring thermocouple's. More measurement points are available by connecting up to 14 controllers to each other wirelessly or with cables. The controllers are designed for any kind of heat treatment consoles and furnaces, and can be mounted inside or to front panel. Hotfoil-EHS is the North America representative for ICE STAR.

Common Types of Process Heating Systems and Equipment

External Electric Vessel Heater

In all process heating systems, energy is transferred to the material to be treated. Direct heating methods generate heat within the material (e.g., microwave, induction, or controlled exothermic reaction), whereas indirect methods transfer energy from a heat source to the material by conduction, convection, radiation, or a combination of these functions. In most processes, an enclosure is needed to isolate the heating process and the environment from each other. Functions of the enclosure include, but are not restricted to, the containment of radiation (e.g., microwave or infrared), the confinement of combustion gases and volatiles, the containment of the material itself, the control of the atmosphere surrounding the material, and combinations thereof.

Common industrial process heating systems fall in one of the following categories:

Large heat treated parts - still red-hot.

• Fuel-based process heating systems 
• Electric-based process heating systems 
• Steam-based process heating systems 
• Other process heating systems, including heat recovery, heat exchange systems, and fluid heating systems. 

The choice of the energy source depends on the availability, cost, and efficiency; and, in direct heating systems, the compatibility of the exhaust gases with the material to be heated. Hybrid systems use a combination of process heat systems by using different energy sources, or different heating methods with the same energy source.

Large, Custom Heat Treat Furnace Fabrication

The video below demonstrates the erection of a 16' x 16' x 62' heat treat furnace built out of a 6x6 I-Beam skeletal structure with 11 gauge steel skin. Full size doors, two per end, will allow the furnace to heat loads using it's full volume. The furnace is equipped with eight 3-Million BTU burners, one at either end and 3 down each side, to circulate the air. Four dampers are included, two at each end. It will move back and forth on a rail system by (16) 10" crane wheels. A hydraulic system will act to lift the furnace 3" in the air off the hearth. This will allow the furnace to move freely and without damaging the insulation on the bottom seals. It will be controlled via a remote HMI screen with full SCADA capabilities.
