In order to keep pace with the technical developments of Industry 4.0, the steel industry is faced with the challenge of retrofitting analogue plants and linking them with IP-based systems to enable seamless visual process monitoring of steel production.

With over 50 years of experience in the development and production of individual solutions for holistic visual process monitoring, is PIEPER a reliable partner and expert in the field of industrial video and safety systems. The wide portfolio of combustion chamber cameras and probes generates high-resolution camera images even under adverse conditions and in high-temperature plants, ensuring an optimal production process and thus providing more efficiency. Thermovision and early fire detection ensure a significant reduction of error sources and risks to a minimum - for the protection of man and machine.


In this way, appropriate measures can be taken in good time and the embers can be cooled before a fire occurs. In the coking plant, the thermal camera system is precisely connected to the extinguishing monitor. This ensures that only the really required amount of water is sprayed with pinpoint accuracy and that the coke is not contaminated. Protect your most valuable resources and rely on intelligent smoke and fire early detection and process monitoring with advanced thermovision!

Iron production in the blast furnace process begins in the coke plant and sinter plant. First, coal is heated to over 1,000 °C in the coking plant and degassed, which produces coke. For the production of pig iron, sinter is also needed as an important auxiliary material, which is produced from iron ore and coke, among other things, in the sintering plant. Both products are then melted into pig iron in the blast furnace at up to 2,200 °C and finally refined into crude steel in the converter together with steel scrap and slag binder. The crude steel is then given its first shape in the continuous casting plant. Rectangular slabs, billets or round bars are produced, which are cut to transportable sizes at the end of this production step. In the hot rolling mill, the shaped crude steel is heated again to up to 1,260 °C and then rolled into sheets. In the cold rolling mill, thicknesses can be reduced again to less than one millimetre for further processing as thin sheet or electrical sheet. Hot-dip galvanising is the final step in steel production: the steel is coated with zinc, which is melted at around 450 °C, to make it weather-resistant and thus protect it from corrosion.


Until now, many processes in steelworks have been monitored manually – and thus only on a point-by-point basis – for cost and analysis reasons. The consequence? A high susceptibility to errors and hardly any possibilities to automate processes and connect them efficiently.

PIEPER accompanies you into the age of digital industry 4.0. A new generation of analyzable IP cameras automatically keeps an eye on a variety of processes using thermal monitoring.

Especially for high-temperature applications, for example in walking beam furnace, PIEPER offers optical full HD sensors. These meet the high demands placed on the difficult environment. In addition, they are high-performance enough to perform customer-specific analysis functions directly on the camera. This helps to stem the flood of data, as the camera only actually stores the information and triggers an alarm if there are deviations from previously defined rules.

Benefit from automated process monitoring and optimal quality of your products!

The art of engineering "Made in Germany": PIEPER is the experienced companion into the age of digital industry 4.0. A new generation of analysis-capable IP cameras keeps an automated eye on a variety of processes using thermovision. The cameras are easy to install and can be quickly connected to the existing network thanks to their ease of use. They are ready for use within a short time.

Efficiency and quality optimisation with visual process monitoring and thermovision from PIEPER - for the decisive step ahead!

Networked quality assurance through visual process monitoring

Until now, many processes in metallurgical plants have been monitored manually - and thus only selectively - for reasons of cost and analysis. The result: a high susceptibility to errors and hardly any possibilities to automate processes and efficiently network them with each other.
