Abstract

1393638 Tuyeres CENTRE DE RECHERCHES METALLURGIQUES - CENTRUM VOOR RESEARCH IN DE METALLURGIE 7 Nov 1973 [10 Nov 1972] 51608/73 Heading F4B Reducing gases are injected into a shaft furnace by tuyeres which slope upwardly towards the interior of the furnace at an angle of 30 degrees or less to the horizontal. The furnace may be a blast furnace, the sloping tuyeres for the fuel gas being positioned above the main blast tuyeres.
