  • Publication number: 20170198372
    Abstract: A method for smelting a nickel oxide ore, wherein the reduction step progresses effectively while maintaining the strength of the pellets, comprises: a pellet production step S1 for producing pellets from a nickel oxide ore; and a reduction step S2 for reducing and heating the obtained pellets in a smelting furnace at a predetermined reduction temperature. In the pellet production step S1, a mixture is formed by mixing materials including said nickel oxide ore without mixing a carbonaceous reducing agent, and the pellets are formed by agglomerating said mixture. In the reduction step S2, in charging the obtained pellets into the smelting furnace, a carbonaceous reducing agent is spread in advance over the furnace floor of the smelting furnace and the pellets are placed on the carbonaceous reducing agent, and the pellets are reduced and heated in a state where the pellets are covered by the carbonaceous reducing agent.

  • Publication number: 20170152584
    Abstract: Provided is a method for producing a pellet capable of suppressing heat shock-induced crack occurrence, when nickel oxide ores are made into pellets and placed in a reducing furnace in a smelting process. In the method for producing a pellet from a nickel oxide ore, a nickel oxide ore, a binder and a carbonaceous reducing agent are mixed, the mixture is made into a lump, and then the resulting lump is subjected to a preheat treatment at a temperature of 350° C. to 600° C. In this preheat treatment, the lump more preferably undergoes the preheat treatment at a temperature of 400° C. to 550° C.

  • Publication number: 20160339747
    Abstract: In a motorcycle tire, since a reinforcement cord that constitutes a belt layer (24) is constituted by a cord having a low modulus of elasticity (a tensile force upon 1% elongation is 15 N or less), a shearing force in a circumferential direction of a tread (26) is decreased. As a result, a value of frictional energy is decreased, and abrasion resistance of the tread (26) (a center section (27)) is improved. Moreover, since tan ? of shoulder sections (28) is larger than tan ? of the center section (27), a grip limit in the shoulder sections (28) that are grounded upon turning is increased, and turning performance is improved.

  • Publication number: 20160320309
    Abstract: In measuring a dissolved substance, a concentration of a specific dissolved substance in a sample water is measured using a measuring water W1 developing a specific color within a specific pH range by adding each of two reagents to a sample water W0, and an acid-base indicator S developing different colors other than the specific color is selected in a first pH range including the specific pH range and a second pH range deviating from the first pH range. Next, a reagent is prepared by adding the acid-base indicator to one reagent wherein a pH value of a reagent added water where the two kinds of reagents are separately added to the sample water is within the second pH range. Next, absorbance values are calculated by three region component lights which are a transmitted light in the measuring water wherein the prepared reagent is added.

  • Publication number: 20150362436
    Abstract: A reagent includes a coloring agent allowing a measured solution to develop a color transmitting a region component light for a dissolved-substance concentration measurement selected from three region component lights of red, green, and blue obtained by transmitting a light including a visible light region to the measured solution colored by addition of the reagent to the sample, and dividing a light of the visible light region of a transmitted light thereof into roughly three portions. Based on the transmitted light from the measured solution with the coloring agent added, an absorbance of the region component light for the dissolved-substance concentration measurement, and an absorbance A3 of another region component light resulted only from the coloring agent are calculated. Whether or not the reagent in a necessary quantity is added to the sample can be judged by comparing the absorbance A3 and a standard absorbance A0.
