摘要： A method of controlling slag coating in a steel converter in which slag is left in the converter after tapping, and a slag solidifying agent is added to the slag to form a coated slag which is used to coat the bottom and/or side wall surface of the converter. The method is performed bya) examining the composition of the slag at the tapping time;b) determining, based on the examined slag and through an equilibrium calculation using thermodynamic data, the amount of solidifying agent per unit weight of the slag necessary for maintaining the liquid volume fraction of the coated slag to a value not greater than about 40% at the planned tapping temperature of the next charge of steel;c) determining the amount of charge of the solidifying agent based on the calculated required amount of the solidifying agent and the amount of the slag remaining in the converter; andd) adding the calculated charge of the solidifying agent to the slag after tapping, to form a coated slag.

摘要： A pressure detecting device for detecting air pressure by means of a pressure receiving member which is energized by a coil spring, wherein a seal is provided between the side wall of the detector housing at the pressure detecting port side and the pressure receiving member as well as between the other side wall of the housing at the discharge port side and the pressure receiving member and further sealing area at the discharge port side is larger than that at the pressure detecting port side.As a preferred application of the pressure detecting device a control system for a press machine is constructed such that operation and stop of the press machine are controlled by way of controlling supply and discharge of pressurized air to and from the press machine with the aid of a double valve and the pressure detecting device.As another preferred application of the pressure detecting device a stroke ends detecting system for a pneumatic cylinder is constructed such that both pressure chambers in the pneumatic cylinder divided by the piston are communicated with the pressure detecting ports of the pressure detecting devices.
