摘要： A slag control shape is releasably mounted on a cover for a molten metal vessel. An actuator is connected to a slag control shape release member to retract the release member from a first position engaged with the slag control shape to a second position separated from the slag control shape to allow the slag control shape to freely drop into the molten metal receptacle. The actuating end of the actuator is located at an easily accessible operator position for remote actuation of the release member. In another embodiment, one end of a cable wound in a plurality of turns about a rotatable shaft mounted in a reel is attached to the slag control shape. A spring biasingly engages the shaft to control the rate of rotation of the shaft and thereby the rate of payout of the cable and the rate of descent of the slag control shape into the molten metal vessel. In another embodiment, the release member is mounted on a lid removably mountable in a bore in the cover and the actuator is mounted on the cover and releasibly connected to the release member. In yet another embodiment, the release member is mounted on a base which is in turn removably mounted in the bore in the cover. The hanger of a slag control shape extends through an aperture in the base and is engaged by the release member on the base.

摘要： In a method for controlling the final carbon content of a steel produced by an oxygen steelmaking process, the weight of the molten steel in the vessel is continuously monitored during the process by means of load cells. The load cells may be placed under the vessel support structure or alternatively within the vessel support structure with trunnions which support the vessel disposed to rest on the vessel. It is found that a minimum weight point occurs in the charge consistently at the same carbon content during steelmaking. The detection of this point is used in the establishment of a relationship between oxygen added after this point and the final carbon content of the steel. Providing that the initial charge weight is fairly constant and the amount of oxygen added after the minimum weight point is known, the relationship, conveniently in the form of a calibration curve, may be used to predict or control the final carbon conent of the steel.

摘要： A process for optimizing steel fabrication. The process includes optimization of treatment in the ladle based on accurate determination of steel weight, slag carryover and furnace heel. The unification of the dip test process together with ladle profiling using information from the slag, side and bottom regions of the ladle results in the quantitative determination of key factors to optimize steel composition with minimum slag carryover in the absence of scales to determine required masses of metal charge and ladle weight as examples. Caprices of the process include significant improvements in ladle refractory and specification steel quality.

摘要： An iron melting furnace has a refractory lined furnace body having a top opening through which raw materials including a raw material iron source, a carbonaceous material and a slag forming material may be introduced. A heating system is provided for injecting oxygen-containing gas into the furnace body to combust the carbonaceous material, whereby combustion heat can melt the raw material iron source to generate molten iron and molten slag to form a molten iron and slag bath. A plurality of tap holes penetrate the furnace body and are provided at positions different from one another in a height direction of the furnace body, and a refractory filling which is different from the refractory liner material fills at least one of the tap holes such that molten iron or slag in the furnace is unable to flow through the tap hole being filled with the refractory material.

摘要： Clean metal pour form a tilting, side-tapped furnace containing metal and slag is maximized by determining metal residuum remaining in the furnace from measuring the liquid metal poured into the receiving ladle and adjusting the furnace tilt angle to minimize vortex formation and minimize slag entrainment. Measurement of the necessary parameters avoids the use of operator judgment. In a preferred embodiment, adjustment of the tilt angle is computerized based on data received from appropriate sensing devices, avoiding both operator judgment as well as operator control.

摘要： A method of tapping a steelmaking furnace comprised of determining a desired level of steel to be attained in a ladle, and calculating the weight of molten steel that will be present when the desired level is attained following a transfer of molten steel from the furnace to the ladle. The furnace is operated such that slag is formed on top of molten steel contained therein. The furnace is moved to a first position to cause transfer of molten steel to the ladle to begin. The transfer of molten steel from the furnace to the ladle is continued, and at the first occurrence of molten steel attaining the desired level in the ladle, molten steel attaining a maximum allowable weight in the ladle, or an excessive amount of slag being present upon the molten steel in the ladle, transfer of molten steel to the ladle is ceased.

摘要： A slag control shape is releasably mounted on a cover for a molten metal vessel. An actuator is connected to a slag control shape release member to move the release member from a first position engaged with the slag control shape to a second position disengaged from the slag control shape to allow the slag control shape to descend into the molten metal vessel. Upon the occurrence of a predetermined condition, such as a predetermined weight of molten metal in the vessel or a predetermined total time of molten metal discharge from the vessel, a controller generates a signal to the actuator to automatically release the slag control shape into the vessel. The controller is located remote from the actuator and transmits the activation signal to the actuator by radio frequency signals, directly through an electrical conductor, or to a light emitter which transmits a light beam to a photodetector mounted on the cover.
