TERMICA specializes in the design and manufacture of high-performance thermal equipment such as pan heaters and heat treatment ovens.
HEATERS
Pan and Tundish Heaters
TERMICA's LH line equipment is designed and built to meet refractory drying and sintering cycles, heating for pouring or both. Versatile, they can be built to suit the pan in a vertical or horizontal position.
V-LH: Vertical Ladle Heater and H-LH: Horizontal Ladle Heater
They are manufactured in compliance with the strictest operational safety standards, in accordance with NBR12313:2000 and NFPA86, in addition to DIN-EN-50156-1.
The great differential of TERMICA's LH line heaters lies in the efficiency of combustion. The heaters can operate with a special combustion combination: Air/Gas/O2, guaranteeing exceptional performance gains.
Thanks to its exclusive TERMWIND © control, it is possible to extract maximum efficiency in drying when operated at low temperatures and in maintaining the pan for running when operated at high temperatures.
As standard, the LH line equipment has Level 2 automation already prepared to be integrated into Level 3 or higher.
FURNACE
TERMICA ovens are customized according to the needs of each process. There are more than two decades of experience designing, building and delivering high thermal efficiency furnaces to the market, meeting standards such as NBR12313:2000, NR12, NFPA86, in addition to DIN-EN-50156-1 and other specific standards. We work with the types:
-
Car-type batch furnace;
-
Campanula-type batch furnace;
-
Conveyor or roller type tunnel kiln;
-
Walking beam type oven.
Our combustion ovens with two combined combustion control systems.
Electric furnaces can be equipped with a demand control system, that is, they can interact with the plant's electricity demand controller, modulating the furnace's electrical power according to the plant's energy availability.
Temperature control is one of the most important premises for the heat treatment process. TERMICA, benefiting from its expertise acquired in the most varied processes, created TERMCAS, a proprietary control strategy, which results in excellent PV stability. With the benefits of AI, the control can be optimized at each cycle .
ELECTRIC OVER FOR
ALUMINUM FUSION
This technology, with no greenhouse gas emissions, allows fusion energy to practically reach theoretical limits. The process is a closed loop with liquid metal recirculating through each zone. Solid filler is added continuously in any form, including ingots, return castings, risers and channels, cuttings and floating scrap such as chips.
The heat of fusion is provided by a bank of immersed heating elements and corresponds exclusively to the energy required by the solids loading rate. The molten metal is then treated to remove dissolved hydrogen and entrained non-metals, and supplemental energy for maintaining the temperature in the system is provided by built-in heaters built-in the refractory walls of the holding section.
Benefits:
-
Zero emissions as it is 100% electric
-
Dramatic reduction in aluminum oxide formation, less cleaning, more product and less waste;
-
Higher productivity and lower operating costs due to the refractory's long life and efficiency;
-
Melting energy directly proportional to melting rate;
-
Predictability, controllability and stability;
-
Heaters operate at high surface load and require comparatively only a small furnace area;
-
Eliminates the risk of contamination, reduces installation and start-up time;
-
Safety measures ensuring metal containment and low cold face temperatures;
-
Ample area for cleaning and sampling without interruption of power supply, plus the operator is not exposed to surfaces significantly above the temperature of the metal.
