摘要： An electric arc furnace (EAF) including a raw material container, a set of electrodes, a set of electrical potential transformers, and a reference signal verification device. The set of electrodes are configured to be controllably extended toward the raw material container. The set of electrical potential transformers are correspondingly coupled to the set of electrodes. The reference signal verification device is configured to carry out the steps of reading a reference signal value coming from the raw material container; comparing the reference signal value to an approximated value; and determining that there is a loss of the reference signal if the reference signal value is not within a predetermined amount of the approximated value.

摘要： A continuous scrap feed into an electric smelting furnace (EAF) having a channel connected at one end to an opening in a wall of the smelting furnace and has at its other end a charging device for the scrap. An extraction device for the off-gases which are guided through the channel serve to preheat the scrap, this extraction device being connected to the channel between the two ends of the channel located closer to the smelting furnace than the scrap feed in relation to the total length of the channel. The extraction device is a single-stage blower whose intake opening is oriented in the direction of the smelting furnace, and the clear cross section of the channel between the extraction device and the scrap feed is adapted to the amount of scrap so that the height of the scrap charge substantially fills the clear cross section.

摘要： Methods and apparatus for processing a metal using a hybrid burner are described herein. The costs of melting and refining metal, such as iron, using standard burners is subject to fluctuation. The hybrid burners described herein are capable of burning both standard fuels as well as solid carbon-containing fuels, like coal. Through the use of a hybrid burner in either standard or modified electric arc furnaces, the costs for melting and refining an iron source can be reduced both through the costs of fluid hydrocarbon fuel sources and through the reduced or eliminated need for external carbon sources during refining.

摘要： An apparatus and method for processing liquid slag and baghouse dust from a steelmaking furnace such as an EAF to recover valuable metals from the slag and dust includes a treatment vessel having a movable lower shell portion for receiving liquid slag and an upper shell portion that couples with the movable lower shell portion during heat activation of the treatment vessel. The slag is combined with silicon dioxide, a reducing agent, baghouse dust, and an inert gas before being heated to between approximately 1400° C. and 3000° C. The heat treatment results in a molten reduced iron and manganese metallic material, a treated slag layer, and an off-gas containing lead, zinc, and carbon monoxide. The off-gas is combusted, cooled, and solidified, resulting in lead oxide and zinc oxide. The slag layer is tapped, cooled, and solidified. The metallic layer is tapped for recycle in the steel making process.

摘要： The present invention is a multi-faceted mobile furnace apparatus. The apparatus has a furnace system, an electrical system, a positioning system and a control unit. The furnace system has a set of movable electrodes, and at least two pour configurations, to transform a solid material into a molten state. The electrical system provides the electrode with a predetermined, yet changeable type of regulation, current, voltage, impedance, power, and/or imbalance of current. While the electrode positioning system moves the electrode, this movement determines if the electrode is properly positioned for the furnace to be an open arc system, a submerged resistance system, or submerged arc system. The above systems are monitored by the control unit. There by the furnace system, the electrical system and the positioning system can all be altered to achieve the most efficient and cost saving method to transform the solid material into the molten state.

摘要： A plasma arc waste treatment furnace is equipped with a plasma arc torch having an electrode formed from a conductive refractory material. The refractory electrode can be operated at very high temperatures and does not need to be water-cooled. This eliminates a need for de-ionized water used in prior art furnaces. Arc erosion takes place very slowly and this results in long operating intervals of the furnace between shutdowns needed for electrode replacement. The electrode can be successfully operated as a cathode and this mode of operation improves melting efficiency.
