The first batching line for ferroalloy production was supplied and commissioned in 2002. In 2002-2008 more than 20 process lines and control systems have been commissioned (Implemented Projects) in order to produce such ferroalloys as: Ferrochrome (FeCr), ferrosilicon (FeSi), ferrovanadium (FeV), ferromanganese (FeMn), ferromolybdenum (FeMo).
SME Tomsk Electronic Company can offer the following for ferroalloy production:

Features of Process Lines
For continuous supply:
- Error in batching out of the maximum production limit is 0.5 - 1% as per GOST 30124-94:
- For continuous batching supporting the preset proportion in the batching mode when batching intermittent doses
- Supporting accuracy of components proportion not worse than 1%
|
For batching:
- Accuracy of batching within 1% as per GOST 10223-97
- Replacement of vibrating feeders with belt ones (those providing delivery of the materials directly from the hopper to the belt feeder)
- Reduction of noise and dust level in the line operation area
|
Charge Materials Techniques
- Intermittent (materials are supplied by batchers to the intermittent conveying line)
- Continuous (materials are supplied continuously by belt feeders to the continuous conveying system)
- Combined (materials are supplied continuously or intermittently to the conveying system operating either continuously or discontinuously)
|
Special Software
- Algorithm aimed to adjust batching and supply of components including correction in case of external disturbances (poor convergence, choking up, changes in the density, material fractions etc.)
- Algorithm for proportion adjustment (components combination) during materials handling supporting the ratio of components not worse than ± 1 % (ASAD)
- Algorithm for desoxidant supply adjustment basing on its humidity and correction of ore materials supply depending on the content of the main component
|
When some upgrade is implemented, the commissioning is divided into stages (with no shutdown of the main production) individually for each project.
