    Japanese iron and steel industry has recently made remarkable progress and ranked third in the production of raw steel in the world.
    A large amount of energy is consumed in the iron and steel industry. Coal is the major source of energy and it will hold the present position in the near future. On the other hand, consumption of heavy fuel oil and electricity is remarkable with the progress of iron industry.
    The author, illustrating the energy consumption in the pig are process, explained how energy was consumed in the actual pig iron making, rolling and steel making processes. He also described the future prospects in the increase of heavy fuel oil consumption, crude oil use, fine coal injection into blast furnace and the increase in the use of domestic coals as raw material for coke.

    Mitsubishi-Westinghouse 10, 000kW gas turbine installed in Asahi Glass Co. Chiba Works has been approved in June 28th 1963 by Japanese Government, and then continuously supplied electric power and the steam which generated by turbine exhaust gas. Total operating hours have reached approximately 6, 000 hours and total generating outputs are about 54, 000, 000kWh.
    The following articles describe the outline of its construction, the major experi-enced troubles and the fuel problem.

  • Grindability of Coal by Hardgrove's Method
    Influence of the Specific Gravity of Sample

    In determinating the grindability of coal by Hardgrove's method, the volume of sample in the testmachine pot will be different owing to the speaific gravity of sample, so that the determined data will be influeneed by the specific gravity of sample.
    And the grindability index of sample, larger specific gravity than standard coal, is inclined to larger than true value. When the grindability index of coal is calculated by the weight of sample through No.200 screen, it is better to calculate as following;
    G.I.=13+6.93w× (γ0/r)-b
    where, w: weight through No.200 screen
    γ0: specific gravity of standard coal
    γ: specific gravity of sample
    b: constant.

  • Mineral Matters and its Utilizations in the Takamatsu Coal
    Michiyasu Sakamoto, Ryonosuke Abe

    Besides pryrite, marcasite, Limonite (or hematite), gypsum and mica recognized under the microscope, the following minerals have been also indentified by X-ray analysis in the Takamatsu Coal and their refuse; they are halloysite, montmorillonite, illite, quartz, feldspars and Calcite, of which halloysite and quartz are commonly involved in each of the preparation products. Because a reasonable amount of halloysite is not rarely included in the second and third class coals, the ashes of these coals are refractory in general, and these coals are, therefore, suitable to the powdered fuels for power plant.
    Montmorillonite and feldspar involved more or less in washery slime might have been originated from tuffaceous shale and sandstone intercalated in the coal seam, because they are easy to be swelled by water and to be removed during coal washing procedure.
    In the research to produce“pesticide diluent”, the above mentioned washery slime is used as a raw material.
    One of the important subject in this research lie in the performance of the structural changes of clay minerals and at the same time, in the combution of the carbonaceous matter in a rotary kiln.
    In this treatment the reactivity of clay mineral will be reduced, and aimed a pesticide diluent obtained.
    Since the rich deposit of tuffaceous shale and sandstone are recognized in the mining set of the Takamatsu colliery and its' vicinity they must be exploited in the near future.
