  • Publication number: 20220177987
    Abstract: A method and system for predicting slopping in a converter occurring during decarburization refining in the converter in which molten steel is produced from a molten pig iron by blowing oxidizing gas to the molten pig iron in the converter from a top blowing lance, or optionally further blowing oxidizing gas or inert gas from a bottom blowing tuyere to perform the decarburization refining of the molten pig iron. The method includes measuring an emission spectrum of a throat combustion flame blowing out from a throat of the converter, calculating emission intensity of the measured emission spectrum at a wavelength in a range of 580 to 620 nm, and predicting the occurrence of the slopping based on a time-series change of the calculated emission intensity.

  • Patent number: 10059546
    Abstract: A sheet conveying apparatus includes a main body, a stack unit having a contact portion and a stack portion on which a sheet is to be placed, a conveyance guide, and a moving member having a contacted portion. The stack unit can be inserted into and extracted from the main body. The conveyance guide can be located at a guide position for guiding the sheet conveyed on a conveying path and a release position for releasing the conveying path. The moving member moves the conveyance guide from the guide position to the release position by moving in a first direction from a first to a second position. The moving member moves from the first position in a second direction opposite the first direction by the stack unit contact portion contacting the moving member contacted portion when the stack unit is inserted to and extracted from the main body.
