    摘要: Systems and methods are disclosed that involve, in the operation of an electric arc furnace (EAF), disposing a composition into a container for smelting in the electric arc furnace. The composition may include EAF fines and carbonaceous fines. The systems and methods involve placing the container and a steel precursor into the EAF to react the EAF fines with the carbonaceous fines and melting the container and the steel precursor. Methods for feeding manufacturing by-products to a furnace for melting in the furnace, including filling a container with manufacturing by by-products including at least one of iron and baghouse dust (BHD), the container having a melting point greater than or equal to a melting point of the iron and a melting point of the iron and baghouse dust (BHD). The method further includes securing the container closed with a lid, charging the container into the furnace, and melting, via the furnace, the container, the iron and baghouse dust (BHD) in the furnace.

    摘要: A gasifier for producing synthesis gas from a widely varying feedstock of waste and natural fuels, the gasifier including an injector system having several integrated lances mounted to a molten metal bed reactor or other gasification reactor chamber. The gasification reactor chamber is required to contain the reaction for the production and collection of a fuel gas. The lances are mounted through the top, side and bottom of the reactor in order to selectively direct materials into the molten metal, slag and freeboard gaseous area above the molten metal and slag.

    摘要: A method and apparatus for conducting a metallurgical process. In one form, iron oxides in the form of mill scale is placed in a container and subjected to heat thereby largely reducing the mill scale and largely converting it to metallic iron that can then be used in steel making processes, such as electric arc furnaces and the like. In one form, the container prevents volatile gases (such as gases given off when oily mill scale is heated) for a sufficient time so that the volatile gases heated to a high enough temperature to maximize pyrolysis and decomposition. In one form, vents are provided in the containers that are aligned with collection vents in the heating furnace so that any volatile gases may be easily removed without loss of large quantities of heat.

    摘要: The invention is directed to a method for processing asbestos-containing steel scrap into useful products, which products can be handled in a safe manner. In accordance with the present invention the asbestos-containing steel scrap is melted in a furnace, which results in destruction of the asbestos fibers. It has been found possible to carry out such a process in an economically feasible manner. In accordance with the invention asbestos-containing steel is heated to high temperature so that the steel melts. As a result the asbestos will be converted into harmless material, which allows for safe handling and processing of the resulting products.
