CMI Thermline has supplied silicon steel heat treating furnaces “world-wide”.
CMI Thermline can provide process line equipment for the heat treatment of all grades of silicon steel strip and for all of the necessary process functions from the beginning to the end including:
- hot Rolled or Cold Rolled Annealing & Pickling Line (APL), also known as Normalizing Line (NL)
- decarburizing Line (DL)
- continuous Annealing (Recrystalization) Line (CAL)
- continuous Coating Lines for MgO, Varnish, etc.
- combination Lines that incorporate the above such as:
- tandem / Duplex Anneal (TAL /DAL)
- coating and Thermal Flattening (TF)
- batch Type Furnaces for High Temperature Annealing
- continuous “Tunnel” Type Furnaces for High Temperature Annealing
To reach your production target for any of the process equipment listed above, CMI Thermline will utilize multiple equipment designs along with our vast experience to apply the latest technology innovations.
To satisfy the different thermal processing cycles (recipes) production output requirements, CMI Thermline will offer the correct combination of:
- heating ---> A combination of different types of heating equipment will be applied to obtain the required thermal recipe:
- direct-fired Furnaces with insulating brick or lightweight fiber insulation and burners for low emissions.
- indirect-fired Furnaces with insulating brick or lightweight fiber insulation and radiant tube burners for low emissions.
- electrically Heated Furnaces with insulating brick or lightweight fiber insulation and “heavy duty” resistance type heating elements selected to accommodate the temperature and atmosphere environments.
- induction Heating Furnaces for fast heating rates where desired or for applications with space restrictions.
- cooling ---> A combination of different types of cooling equipment will be applied to obtain the required thermal recipe:
- static Cooling (Water Jacket)
- static Air Tube Cooling
- slow Jet Cooling
- fast Jet Cooling
- water Spray
- strip Transport ---> A combination of different types of strip transport conveyor roll equipment will be applied to accommodate the required thermal recipe:
- dry Rolls
- water Cooled Rolls
- coated Rolls
- automation and Control ---> A clever combination of different levels of control of the complete thermal process:
- level 1 Programmable Logic Controller (PLC)
- thermal Recipes
- mathematical Model (patented L-TOP® ) for process optimization
- tele-maintenance using remote control & assistance
- Temperatures ( as high as 1260°C) and associated heating rates according to the thermal process defined
- Specific cooling rates according to the thermal process defined (also in consideration of strip flatness and thermal homogeneity
- Control of furnace atmosphere according to the thermal process defined
- Reduced energy consumption with the right choice of heating technologies
- Reduced energy consumption with the right choice of cooling technologies
- Throughput production maximized and energy consumption minimized with the right choice of control and modeling technologies
- Strict respect of proprietary process KH of our Customers
Compared to conventional furnaces without optimized heating, cooling and modeling latest technologies, consumption may be reduced in a range of 5 to 10%
