摘要： A process which enables high-chromium alloy such as ferrochromium heretofore obtained by the use of electricity to be produced less expensively in higher yield of chromium by the smelting reduction using solid carbonaceous material such as coke in the place of electricity.The process of smelting reduction is so performed in the top and bottom blowing converter divided into two stages: the first stage for carrying out the converter operation under continued supply of the raw materials containing pre-reduced chromium oxide (chromium ore) and the second stage for carrying out the converter operation under suspended supply of the raw materials containing the pre-reduced chromium oxide, and the first stage of converter operation is carried out under conditions such that the temperature of the molten metal remains at or below 1,650.degree. C. and the ratio of the volume of the gas generated per minute by the substances supplied through the tuyere for bottom blowing to the combined weight of the molten metal and the molten slag falls in the range of 100 to 2,500 [Nl/min.t] and the second stage of converter operation is carried out under conditions such that the temperature of the molten metal remains at or below 1,650.degree. C., the ratio of the volume of gas generated per minute by the substances supplied through the tuyere for bottom blowing to the combined weight of the molten metal and the molten slag falls in the range of 100 to 1,800 [Nl/min.t].

摘要： In producing a mixed phosphatic fertilizer, humic acid is mixed with fused phosphate to cause the humic acid to react on alkaline ingredients of the fused phosphate for turning these alkaline ingredients into chelate compounds, so that water-soluble phosphoric acid contents of succeedingly added phosphatic fertilizers such as calcium superphosphate and calcium triple-superphosphate are not reduced or insolubilized by being reacted with such alkaline ingredients. Thus, unlike the prior art, a stabilized predetermined level of water-soluble phosphoric acid contents can be secured in the resultant mixed phosphatic fertilizer along with a predetermined level of citric acid-soluble phosphoric acid contents.

摘要： A method for removing scale from a turbine blade in a geothermal power generation system has been developed. The developed method for removing scale from a turbine blade is characterized in that an alkaline solution and a chelating solution are injected into geothermal steam flowing into a turbine during power generation and geothermal scale formed adhering to the turbine blade is removed using the injected solutions. The present removal method can remove the scale adhering to a geothermal turbine blade in a short amount of time by improving the scale removal effect than heretofore. Further, a method for geothermal power generation preventing scale adhesion to the turbine blade is provided and a geothermal power generation system can be provided that enables continuous operation without performing opening and cleaning the turbine, even when geothermal steam containing 0.1 ppm or more of SiO2 and/or Cl is introduced into the turbine.
