ANDRITZ to supply plants for pickling, acid regeneration, silicon removal and acid purification to voestalpine

The ANDRITZ equipment will enable the customer to perform pickling and cold rolling in a combined plant in future in cold-rolling mill #3. In addition, the world’s most modern acid regeneration plant will be built, complying with the highest environmental standards, and also enabling flexible production of high-purity iron oxide. An underground route for the transfer of media between the individual plants completes the package.

The main features of the various plants are as follows:

• The continuous pickling plant is designed to process advanced steel grades as well as special materials for the electric mobility of the future. This pickling plant has a capacity of around two million tons per year and operates with hydrochloric acid that is recycled in a regeneration plant.
• The world’s most modern acid regeneration plant meets the strictest requirements for exhaust gas treatment and wastewater. By achieving recovery rates of almost 100% and reusing various media, the plant makes a substantial contribution towards environmental protection and sustainability.
• Highly pure iron oxide – an important raw material in the electric mobility sector for example – occurs as a by-product of the acid regeneration process. A separate acid purification plant will also be installed.
• Several systems for removing silicon from the acid loops contribute towards ensuring smooth operation and highest availability as well as top-quality pickled steel strip.

This order once again confirms the successful collaboration between ANDRITZ and voestalpine over many decades. ANDRITZ has already supplied several galvanizing plants for steel strip used in automobile production and several acid regeneration plants to voestalpine as well as being a dependable partner to voestalpine for rebuild and modernization projects.
