Whoever wishes to supply high-performance refractory products successfully and in the long-term to the market must give Research and Development a broad platform. Therefore, Refratechnik Steel has two development departments, one for shaped products at Göttingen and the other one for monolithics at Bendorf.
The primary objective of these departments is to develop new products and constantly optimise existing products. In both development and production, as well as in the use of products, environmental protection is always at the forefront of our work. The journey from the conception of an idea through to its successful implementation sees new products undergo many complex development stages. Starting with the first laboratory tests, pilot production and ultimately practical testing, ideas are put into practice and introduced as products to the market. The close cooperation with our customers greatly assists the development of high-quality refractory products.
R & D Bendorf (Monolithics) The Monolithics Department of Refratechnik Steel GmbH was founded in January 2001. In the meantime, a dedicated laboratory and management building have been built on the factory premises of Refratechnik Steel GmbH at Bendorf. The core area of monolithic developments is to be found in the iron and steel industries, non-ferrous metallurgy (aluminium industry), power stations and in all industrial sectors utilising thermal processes. In addition to refractory concretes (RC, MCC, LCC, ULCC and NC), dry gunning concretes, JETCAST® concretes (shotcasting), and ceramically or chemically bonded ramming mixes are being developed.
In many industrial sectors, our developments in monolithic products are leading the market. In the field of blast furnace shaft lining, alkali and CO-resistant products have been developed and tested in all installation technologies (casting, dry gunning, jetcasting). In this case, Refratechnik Steel GmbH is one of the few producers which also supplies products for hot repairs in the jetcasting process.
