A method and a device for charging a plurality of reduced iron raw materials into a traveling hearth reduction-melting furnace and treating the raw materials, allowing sufficient input of heat to the reduced iron raw materials on a hearth covering material to improve treatment efficiency are provided. The reduced iron raw materials are released downward from the lower surface of a ceiling of the reduction-melting furnace to be set on a hearth covering material on a hearth and reduced on the hearth covering material. The falling reduced iron raw materials are given a horizontal velocity having a direction equal to the travel direction of the hearth and being greater than the travel speed of the hearth to enable the reduced iron raw materials to roll in the same direction as the travel direction of the hearth after landing on the hearth covering material.

A screening apparatus comprises superposed screening decks with an upper one of the screening decks having a pellet input, and each screening deck ends with an oversize pellet output, the screening decks have screens to screen the green ore pellets from top to bottom, the oversize pellet outputs feeding the travelling grate through pellet chutes with the oversize green ore pellets of one of the upper and the lower one of the screening decks being superposed to oversize green ore pellets of the other one of the lower and the upper one of the screening decks, the pellet chutes defining a curved delivery path with an input slope at the chute pellet input greater than an output slope of the chute pellet output to reduce a delivery speed of the green ore pellets from the oversize pellet output to the travelling grate. There is also provided a method for screening and delivering green ore pellets onto a travelling grate of an induration furnace.

A carbon baking furnace has at least one vertical baking shaft with a system and method for positioning green carbon bodies to be baked at the top of the vertical baking path and ringing the green carbon bodies with a sacrificial medium such as packing coke. The disclosure provides a system and method for controlling the delivery and removal of the sacrificial medium used to surround the carbon bodies within the baking paths. A volatile extraction system and method are provided. A system and method for unloading baked carbon bodies is disclosed.

Systems and methods for generation of porous silicate aggregates are disclosed. For example, the manufacturing systems may include a conveyor element, multiple hoppers positioned over a first section of the conveyor element, one or more derricks and/or holding elements to move and/or hold the hoppers, a kiln positioned with respect to a second portion of the conveyor element, and/or computing components to allow for control of the components of the system. The system may produce single-layer products in a continuous fashion, multi-layered products having multiple physical and/or chemical properties, and/or more than one product at a time.

An installation for treating material having a treatment chamber equipped with an envelope which separates a controlled atmosphere which is present in its interior from an atmosphere which is present outside the envelope and a housing which delimits the treatment chamber. At least one supporting roller for conveying the material is arranged at least partly inside the treatment chamber. One or more mounting apparatuses for mounting at least one supporting roller are arranged outside the housing. A flexible compensating element is provided between at least one mounting apparatus and a wall, which is associated with the latter, of the housing, there being provided a sealing arrangement which is connected to said compensating element and which separates the at least one mounting apparatus from the atmosphere which is present inside the envelope.
