Abstract: Provided is a non-transitory computer-readable medium storing a program for causing a computer to execute the steps including a step of subjecting a sample containing microorganisms to mass spectrometry to obtain a mass spectrum, a step of reading a mass-to-charge ratio m/z of a peak derived from a marker protein from the mass spectrum, and an identification step of identifying which bacteria of serovar of Salmonella genus bacteria the microorganisms contained in the sample contain, based on the mass-to-charge ratio m/z, wherein at least one of two types of ribosomal proteins S8 and Peptidylpropyl isomerase is used as the marker protein.

Abstract: The present invention discovers a new structural design technique which provides clearances between refractories 13 and fills the clearances with various types of refractories or refractory materials like in the past and, furthermore, uses another method to secure the heat expansion absorption function and provides a hearth structure of a rotary furnace hearth 1 able to prevent contact between the hearth structure and furnace side walls 3 and 4 caused by heat expansion of the refractories 13 and realize safe and smooth operation, that is, a hearth structure of a rotary furnace hearth laying two or more layers of refractories between side blocks 9 and 10 built at the inner circumferential end and outer circumferential end of a hearth refractory bed 7 of a rotary furnace hearth 1 and laying a powder or pellet hearth material 16 on its top surface, the hearth structure of a rotary furnace hearth 1 characterized by using refractories having a compressive strength of 0.1 to 5 MPa at 800 to 1500° C.

Abstract: A rotary furnace hearth wherein a hearth carriage carrying a hearth comprises a plurality of hearth carriages respectively having propulsion systems, wherein adjoining hearth carriages are coupled by coupling bolts and nuts via spacers interspaced in a single row in a horizontal plane, whereby even if the hearth carriages deform due to heat at the time of operation, they are structured to be able to freely deform without mutual constraint in the event of curved deformation, so the hearth carriages are maintained in individually stable states at all times.

Abstract: A reduced iron discharging screw conveyer is provided in a rotary hearth furnace and discharges reduced iron out of the rotary hearth furnace. The rotary hearth furnace produces the reduced iron by charging and heating a pellet including metallic oxide and coal material onto a rotary hearth rotating in a horizontal plane. The reduced iron discharging screw conveyer has a rotary shaft and a screw blade which is spirally formed on an outer surface of the rotary shaft. A lead angle ? of the screw blade 5a satisfies a condition of “0.46 rad ???0.79 rad”. A ratio (h/D) between height h of the screw blade and an outer diameter D of the screw conveyer is smaller than 0.2, and a ratio (t/h) between thickness t and height h of the screw blade is larger than or equal to 0.12.

Abstract: [PROBLEMS] It is an object to provide a reduced iron discharging screw conveyer of a rotary hearth furnace, which can reduce maintenance frequency of the screw conveyer and improve operation rates of the rotary hearth furnace by extending wear life of a screw blade of the screw conveyer. [SOLVING MEANS] A reduced iron discharging screw conveyer 5 which is provided in a rotary hearth furnace and discharges reduced iron out of the rotary hearth furnace, the rotary hearth furnace producing the reduced iron by charging and heating a pellet including metallic oxide and coal material onto a rotary hearth rotating in a horizontal plane, the reduced iron discharging screw conveyer has a rotary shaft and a screw blade which is spirally formed on an outer surface of the rotary shaft. A lead angle ? of the screw blade 5a satisfies a condition of “0.46 rad???0.79 rad”. A ratio (h/D) between height h of the screw blade and an outer diameter D of the screw conveyer is smaller than 0.

Abstract: A furnace sidewall structure of a rotary hearth furnace for making direct reduced iron which is agglomerated iron ore or waste iron oxide containing a reducing agent on a rotary hearth by heating or for heating at least one steel piece, wherein the rotary hearth furnace includes an outer furnace sidewall and an inner furnace sidewall, wherein at least one of the outer furnace sidewall and the inner furnace sidewall is polygonal. The furnace sidewall structure can be prepared with lower manufacturing costs relative to conventional circular profile rotary hearth furnace with respect to the furnace sidewall. The production thereof is easy with respect to manufacturing and with respect to the fact that the dimensional accuracy of the manufactured furnace sidewall can be easily adjusted. Also, there is associated a shorter installation/construction work period and a reduction in the installation/construction cost.

Abstract: The invention provides a raw materials feeding apparatus capable of uniformly dispersing and feeding into a furnace agglomerated raw materials that are likely to undergo dusting, deformation and mutual adhesion. In a raw material feeding apparatus for a rotary hearth furnace, for feeding raw materials to a rotary hearth furnace by using a flat belt conveyor, the invention employs a construction in which a scraper for guiding the raw materials on the flat belt conveyor to a side surface of the flat belt conveyor is arranged obliquely to a traveling direction of the flat belt conveyor. Preferably, the scraper is arranged in such a manner as to guide the raw materials to both sides of the flat belt conveyor.
