From the view point of productivity, improvement in open-hearth furnace means shortening the time for each heat and keeping high production rate for a long period. Productive characteristics of open-hearth furnaces are expressed in formulas using the characteristic constants K (the latent production rate at initial state) and a (the decline of production rate per production of unit amount), which make it possible to compare a variety of open-hearth furnaces each other as to their productivities. Many factors affect K and a, they are mainly related to types and arrangement of the following constituents : (1) The checker chamber, the fantail and the slag pocket (2) The air-uptake and the end wall (3) The furnace head (end roofs, dog houses, side walls and throats) (4) The fuel jet (5) The furnace chamber (ceilings and walls) In studying the factors throughly and extensively to improve open-hearth furnace rationally, it is more easy, more efficient and less expensive to study them by means of small-scale models. Model experiments under suitable considerations represent phenomena in actual furnaces satisfactorily. When an open-hearth furnace or other furnaces are built, they willbe designed rationally by the aids of model experiments. The method is not a quite new one, but it has been applied as an indispensable procedure in the case of aircraft or ship building.
