Production Management
Production Management makes the entire mining process transparent from excavation to ore processing. At the same time, it facilitates vertical information flow from production control level to the ERP system. Network solutions from Siemens provide both the infrastructure for exchanging data in the field and high-performance data highways for linking the areas together.
Security Systems
Security Systems provided by Siemens take plant security as well as data security into account. Thus, providing a complete security system for your employees, equipment and information.
Service and Maintenance
The maintenance of your plant is a substantial cost factor. But even though it accounts for up to 40% of ongoing operating costs, it is the only alternative to unplanned downtime. That makes it even more crucial to optimize maintenance processes – for the performance of your equipment and your mine.

Discontinuous Mining
SIMINE DICONT optimizes the individual process steps in discontinuous mining and the entire process chain. Modules of this overall solution are proven solutions with innovative features for draglines, shovels, trucks and conveyor belts. Individualized matching of these modules to one another produces synergies for more performance, security and availability of all equipment.
Minewinder
The performance of underground mines depends critically on the capability of the hoisting equipment. The aim is to increase this capability without endangering the safety of persons during the transport in the shaft.
Benefication Plant
Being competitive in this case means increasing output while at the same time reducing wear and tear and costs for service and repairs. Solutions from Siemens allow you to meet all these requirements.

Tandem Cold Mill
Competence for your success
From batch to continuous mode
voestalpine Stahl, Linz, Austria
Production capacities of tandem cold mills using coil-to-coil operation are typically in the range of 600,000 to 800,000 tons per year. Today many of the existing batch mills are extended and modernized to continuous mode and new mills are installed for continuous operation from the very beginning. Depending on the product mix, production capacity of these continuous mills can reach 1.2 million tons per year or even more, and many quality parameters can be improved.
4-high and 6-high technology
Our technological and process automation experience in 6-high and 4-high technology makes Siemens VAI a unique partner for your cold mill. Our goal with SIROLL CM is to deliver a solution that offers maximum added value for your production. Advanced mill stand actuators will bring the benefits of improved yield, user-friendly mill operation and high strip quality. Both 4-high and 6-high solution bring specific benefits, and our analysis of the customer’s overall requirements will define the best suitable technological solution. Our approach has been rewarded, for example, by top steel producers voestalpine Stahl (5-stand, 4-high, SIROLL Smartcrown®) and CORUS Staal (4-stand, 6-high), which have selected us to supply the latest tandem mills in Europe. Both companies are dedicated to producing AHSS (advanced high-strength steel grades).
Technical features
- SIROLL Smartcrown contour roll associated with axial roll-shifting for enhanced flatness control
- 4-high and 6-high mill stands for high mill flexibility for all products
- Morgoil® bearings or roller bearings depending on application
- Physical-based analytical online models supported by neural networks ensure accurate mill setup to achieve tight tolerances right from the start
- Flexible thread-in and thread-out strategies for all kinds of materials, such as high-strength steel grades
- Patented compensation systems for correcting periodic roll and coil eccentricities
- Use of last stand in temper mode for smoothing or roughing strip surface
- Fully automatic operation allows operators to concentrate on product quality; actual operator intervention is reduced to an absolute minimum
Nonstop production possible for any existing tandem mill
Tangshan, China
In recent years, the most newly installed tandem cold mills have been continuous operation mills, which indicates that this type has displaced the traditional batch mill. The reason is clear: the productivity of a continuous mill is significantly higher (up to 40%) than a batch mill. One significant factor in this improvement was the development of laser welders. The weld seam produced by these laser welders and the modern control techniques allow minimum loss of time and material. As a result, later conversion of a batch mill into a continuous mill is a typical market trend of the early decade of this century. Generally, any existing non-continuous tandem mill of any line layout can be converted into a continuously operating mill with the use of suitable strip turning units, the right equipment and careful arrangement of all mill and logistic facilities.
Additions for continuous operation
Siemens VAI offers the following equipment for the continuous operation of your mill:
- Welders (flash butt and laser welders)
- Accumulators (2-, 4-, or 6-strand) at one or two levels
- Scale breakers
- Side trimmers
- Bridles for decoupling the tension of the different line sections
- Exit sections with flying shear and 2 reels or carrousel coiler depending on the strip thickness
Main benefits
- Highest production rates
- Optimized yield
- Reduced roll consumption
- Flexible production
- Tight tolerances for strip thickness, shape and high surface quality
- Low costs for operation, maintenance and minimum down times
