For more than 20 years, Tetronics has supplied Tundish Plasma Heating (TPH) equipment to some of the most important steel companies in the world where the technology has delivered many proven quality and productivity benefits for our customers. This technology has been used to control the temperature of carbon, alloy and stainless steels and has been fitted to all major types of casting machine. Controlling the temperature of the steel entering the continuous casting mould is a central feature of all steelmaking practices. Great efforts are made throughout the steelmaking and casting process to ensure that the steel has the correct superheat at each stage of its journey. However, significant variations in casting temperature still occur and these variations lead to a range of problems in steel quality and caster operation. Tetronics’ TPH technology enables the steelmaker to keep the superheat within the optimum range at the last point before it enters the mould.
