Abstract

Cutting precision in the continuous casting process is one of the key factors to reduce waste, optimize yield and assure customer satisfaction by accuracy and consistency in delivered goods. No matter if the customer is an external buyer or the rolling mill next door, assurance that volume and weight of the delivered slab or billet meets the specifications will increase efficiency, thru-put and profit. “Value added” will be obvious at an earlier stage in the production process. This paper will present three different methods of measuring length in the continuous casting process. The applicability of the methods depends on factors such as space, accuracy demands, available funding, company strategy, technical level, maintenance requirements etc. The methods are: A. pulse counting by a contact wheel; B. triangulation laser in combination with photo cells; C. laser Doppler technology.
