The design of BF hearth and inner profile,and the application of copper cooling stave are discussed from the point of view of a front-line operator.The criteria of proper furnace design mainly depend on the possibility of making the operation adjustment to increase the production and reducing consumption.It is believed that the design of composite structure of large carbon brick+ceramic is more suitable for the hearth;the depth of the salamander should be enough to let the dead-man float;the belly angle and the furnace body angle should be controlled at 73 °-78 ° and at 82 °-84 ° respectively;one sec-tion copper cooling stave is enough for the furnace body,and the cooling stave should not be too long.It is suggested that the design parameter should adapt to the external condition,i.e.the design of furnace inner profile should adapt to the external conditions,such as the equipment level,conditions of raw materials and fuel,construction cost etc.
