Ferromanganese / Silicomanganese SAF

• Large capacity semi-closed or closed furnaces
• Annual production capacity depending on raw materials specifications.
• Can be operated to produce Ferromanganese or Silicon manganese as primary product, or batch operation where Silicon manganese is produced from Ferromanganese slag
• Option of scrubber system (for closed furnace designs) or bag filter systems (for semi closed furnace designs) for cleaning of off-gas.
• The complete material handling, including batching plant can be designed
• A hot metal tapping solution that meets customer needs

Tenova specializes in Submerged and brush Arc Furnace design for smelting projects which provides continuous and efficient operations. Tenova 's leading edge technology and depth of experience is displayed by the fulfillment of our passion for continuous improvement and providing the best available technology to our customers.

Fundamental process knowhow enables each furnace design to incorporate:

• Project process design, incorporating impact of customer specific raw material composition; this ensures that the systems such as the batching plant, off-gas cleaning system is designed with flexibility required to achieve stable peak power input and hot metal quality regardless of input material chemical compositions

Tenova projects incorporate latest technologies such as:

• Efficient furnace off gas cleaning systems
• Tenova AutoFurn® automatic furnace controller software
• Integration with Tenova Digital products technology portfolio

Safety is at the core of Tenova’s designs. Not only is physical barriers considered for moving areas, intelligent instrumentation is used to constantly monitor ambient air quality in the furnace building, and complex algorithms applied to determine potential upset conditions and proactively react.

Robotic technologies are also being implemented to remove workers from potentially risky areas.

Access control is an integral design of the furnace building, to ensure no uncontrolled access to potentially hazardous areas.

Tenova’s proprietary Autofurn® furnace control is at the heart of the process control system. The complete plant is fitted with state of the art automation and control systems, designed to not only provide optimum control, but also pro-actively identify potential maintenance areas.

Tenova offers a suite of digital products that complements the core automation system. This includes the development of KPI, production forecasts, early notification of preventative maintenance works and the ability (subject to customer preference) the ability for Tenova process specialists to assist remotely with process fault-finding and optimization tasks. AutoFurn® is designed to be user friendly. It improves the efficiency of furnace operations by obtaining a higher power input to the furnace and maintaining stability and balance in the furnace. It is suitable for new and can be easily retrofitted into existing furnaces. AutoFurn® can be configured to suit different ferroalloy processes, as well as other reduction processes such as base metals, mineral wool and platinum group metals. 

Data is presented to operators via responsive human machine interfaces, including reports and trends, accessed from compatible web browsers. This also enables the customer to make us of the innovative Tenova PyroMobile application from alternative locations.

Tenova uses cutting edge technology to ensure that environmental protection and compliance with legislation are integrated into the design of each smelting plant. Tenova furnace off-gas scrubbers used with closed furnaces and bag filters used with semi-closed and open furnace ensure that gases from smelting processes are cleaned of particulate matter before the cleaned gases are vented to the atmosphere.

Where needed, the furnace is fitted with a secondary fume evacuation system that captures fugitive emissions around the furnace. Tenova recommends that a suitable Tenova gas cleaning solution be used to ensure optimal furnace performance.

Tenova EDGE® is Tenova’s proprietary developed interface to facility all data management, giving customers peace of mind when sensitive data is exchanged.

Authentication an authorization of any data exchange can be defined and customized in compliance with each customer’s specific IT department policies.
