    摘要： The invention discloses a self-adaptive hanging structure of a converter, including vertical connecting rod mechanisms connecting the lower edge of a backing ring body and a lower half converter body of the converter, and horizontal connecting rod mechanisms connecting the upper edge of the backing ring body and an upper half converter body of the converter; the horizontal connecting rod mechanisms are located above the vertical connecting rod mechanisms, the plane where the axis of a trunnion on the backing ring body and the axis of the backing ring body are located serves as the first reference plane, the symmetric center of each vertical connecting rod mechanisms is located in the radiation area of the first included angle, the two planes forming the first included angle coincide with the axis of the backing ring body, and the included angles being 15 degrees and 50 degrees are formed between the two planes and the first reference plane respectively. The invention makes the converter tilting without abnormal noise and running stably, which not only eliminates the super-static over-constraining problem, but also facilitates the converter suspension connecting rod mechanism to adapt to the working conditions, improves the service life of the hanging mechanism, makes the equipment long-term maintenance-free, realizes the main parts interchanging of the connecting rod mechanism, reduces equipment spare parts and equipment maintenance workload.

    摘要： An industrial installation for recovering waste radiative heat from steel slag includes: a pit in which molten steel slag is discharged and from which solidified steel slag is removed, using a slag conveying machine or vehicle; an evaporating device for producing hot water and steam and auxiliary equipment, the evaporating device including a heat exchanger having tube-cooled walls; a steel structure supporting the evaporating device; and a lifting system including jacks, such that the heat exchanger is movable vertically from an upper standby position to a lower working position and vice versa. The tube-cooled walls are made of a metal, allowing the heat exchanger to work in an environment presenting sharp temperature gradients and corrosion.

    摘要： Some variations provide a carbon-negative carbon product that is characterized by a carbon intensity less than 0 kg CO2e per metric ton of the carbon-negative carbon product, wherein the carbon-negative carbon product contains at least about 50 wt % carbon. In some embodiments, the carbon intensity is less than −500 kg CO2e per metric ton of the carbon-negative carbon product. Other variations provide a carbon-negative metal product (e.g., a steel product) that is characterized by a carbon intensity less than 0 kg CO2e per metric ton of the carbon-negative metal product, wherein the metal product contains from 50 wt % to 100 wt % of one or more metals and optionally one or more alloying elements. In some embodiments, the carbon-negative metal product is characterized by a carbon intensity less than −200 kg CO2e per metric ton of the carbon-negative metal product. The carbon-negative metal product can contain a wide variety of metals.

    摘要： Disclosed herein, in some aspects, are systems and methods for producing a material comprising iron through self-reduction of iron ore using bio-oil and/or other reducing agents (e.g., bio-based reducing agents), such as biocrude, ethanol, or other bio-based liquids or biologically sourced liquids. The bio-oil and/or other reducing agents can be mixed with the iron ore to form a furnace mixture, which can be heated, such that the components of the bio-oil and/or other reducing agents in the furnace mixture reduce the iron ore to form an iron product (e.g., a material that includes metallic iron). In some cases, the pre-formed furnace mixture allows for the reducing agents to interact with the iron more readily, thereby providing for quicker reaction rates, and thereby quicker reduction of iron ore, as compared to direct reduction iron production.

    摘要： An electric furnace has a burner directed toward furnace contents. The burner includes a powder-feeding pipe, a jet hole for jetting a fuel, and a jet hole for jetting combustion-supporting gas. Hydrogen gas or a hydrogen-enriched gaseous fuel is jetted as the fuel to form a burner flame. An auxiliary material is jetted through the powder-feeding pipe so that the auxiliary material passes through an inside of the burner flame. According to a steelmaking method, an electric furnace has a burner that includes a jet hole for jetting a fuel and a jet hole for jetting combustion-supporting gas and that jets a flame through the jet holes toward an inside of the electric furnace. Hydrogen gas or a hydrogen-enriched gaseous fuel is used as the fuel of the burner, and an auxiliary material is blown in to pass through an inside of the flame formed by the burner.
