Primetals Technologies has developed and introduced the Through-Process Optimization (TPO) solution, which targets the smart, digital interconnection of various process units and the accumulation of know-how along the entire steel-production chain. With Through-Process Know-How (TPKH) we apply our comprehensive knowledge to improve the performance of our customers by advising them on product development and on producing new, high-strength steels. This expert know-how will be made available as Expert Rules in our Through-Process Quality Control system (TPQC). TPQC is a quality control system for steel production, which helps to continuously monitor and manage quality across all production processes throughout the entire production chain. Consulting, Studies, Trainings and Data Analysis completes the portfolio of Through-Process Optimization (TPO).
Through-Process Quality Control is a quality management system intended to cover the whole production line from the liquid phase to the finishing and packaging lines of the final end product.
TPQC collects all process parameters and measured production data starting in the liquid phase until the final product leaves the packaging line for shipment. The system allows in depth analysis of process data based on time or length of product.
TPQC is optimizing performance by applying know-how based rules for quality decisions, monitoring performance by Key Performance Indicators (KPIs) and stabilizing production by applying advanced Statistical Process Control (SPC). The centralized storage of high resolution process data across the entire production route allows intelligent data analytics for product optimization and development of new steel grades within a short time.
Main features of TPQC:
- Centralized, high resolution process data storage
- Full product genealogy
- Quality assistance by rule-based checks (Rule Editor)
- Root-Cause Analysis / corrective & compensational action
- Product Explorer for process data inspection / product comparison
- Product grading
- Key Performance Indicators (KPI)
- Statistical Process Control (SPC)
- Interface to data mining platforms
- Data cube for multidimensional analysis of KPI’s, quality and production data
- Comprehensive reporting and data visualization

Through-Process Know-How Services support steel producers to optimize their quality and performance along the entire production chain. We support our customers with our know-how to produce high-end steel grades at best quality and costs.
We have tremendous knowledge capital within our company. This knowledge covers every stage of the value chain – from innovation, sales and project execution to commissioning, best practice operation and service. Now we use this knowledge to develop new business models in order to help our customers master their problems. Our technologists and metallurgists advise the customer on product development and on producing new, high-strength steels that are increasingly in demand. We will assist our EA colleagues in establishing the necessary knowledge platform for Through-Process Quality Control (TPQC), an important element of Industry 4.0. In short, we apply our knowledge to improve the performance of our customers.
Main portfolio of TPKH services are:
- Product development for AHSS grades
- Implementation of know-how Rules in TPQC
- Setup of Key Performance Indicators (KPIs)

Tangshan Iron & Steel (HBIS Group)
Type of project
Supply of Through-Process Optimization package covering all process units from steel plant to annealing and galvanizing lines
With the order for a new cold rolling complex at Tangshan, Primetals Technologies provided a TPO package to ensure the efficient production of AHSS and high quality steel grades. The newly developed TPQC system was installed at the upstream facilities (steelmaking and hot rolling) and at the new CRM complex which compromises of a PLTCM, CAL and 3 Continuous Galvanizing Lines. The experts of Primetals Technologies implemented intelligent rules, Key Performance Indicators and Statistical Process Control to ensure the production of best quality products. In addition numerous training sessions for Quality Management, Maintenance Management, Product Development and Daily Management have been provided.
