Introduction of an environmentally sound heat treatment for the emission of the cauterization process of large steel plates

Cel

The aim of the proejct is to replace the traditional cauterization surface treatment of steel press plates used up to now. The complete heat treatment is to be carried out within an inert gas atmosphere in order to eliminate waste and sewage and to spare transport resources. The set-up of the new clean heat treatment equipment especially considers economical and ecological aspects.

C.A. Picard, a middle-size company located in Remscheid Germany, processes large quantities (50 tons per month) of raw steel sheets for the production of industrial press plates. The process includes hardening and tempering of the sheets. Up to now this heat treatment takes place in exposure to normal atmosphere, that is to say: under the influence of oxygen. This process brings about the formation of a scale layer on the steel surface which has to be removed through cauterization with sulphuric and fluoric acids and water for the rinsing process. All of this generates large quantities of chemical waste that has to be disposed of properly. The cauterization process can be avoided by introduced a new clean technology, namely the heat treatment under the influence of an inert gas atmosphere. The technological feasibility of the project is given. However, due to the large sizes of the steel sheets (1800 mm x 5500 mm x 2.5 mm), it takes special efforts to construct the equipment in such a way that the quality of the produced press plates remains intact. By avoiding cauterization, this new technology does not only contribute to unburden the environment and to stop the generation of chemical waste water, but it also considerably saves energy. The omission of the troublesome steel transport to the off-premises cauterization treatment and the optimal use of energy within the new installation through heat recycling additionally reduce the carbon dioxide emission. Especially in the region around Remscheid with its innumerable small and middle-size companies (ie enormous production of saws and saw blades), the introduction of a new clean technology deserves exemplary status, worth being sponsored as a demonstration project.
