摘要： PURPOSE: To quickly find out exact pelletization conditions by solving the material balance equation into which a pelletization speed function is incorporated for each of grain sizes, estimating the change of the grain size distribution of pelletized particles with time and adjusting the conditions for pelletizing raw materials and the conditions for operating pelletization.
CONSTITUTION: The pelletization speed function to express the propability at which the particles meeting each other in a pelletizing machine combine each other is incorporated into the material balance equation to express the grain size distribution according to the progression of the pelletization. The equation is solved for each of the grain sizes to estimate the change of the grain size distribution with time according to the growth of the pelletized particles. The grain size distribution after the execution of the prescribed pelletization stage is determined from the estimated value. The conditions for the pelletizing raw materials and the conditions for operating the pelletization are adequate if the grain size distribution obtd. in such a manner coincides with the standard value. The conditions forthe pelletizing raw materials and the conditions for operating the pelletization are returned to a setting stage and the new conditions are set when the grain size distribution does not coincide with the standard value. The similar operations are thereafter carried out and the operations are repeated until the calculated value coinciding with the target grain size distribution is obtd.

摘要： PURPOSE:To enable secure removal of accumulated material stocking to the internal wall surface of a cyclone for dust removal from high temperature exhaust gas by providing an impact particle supply device in the lower half of the cyclone and introducing impact particles into the cyclone. CONSTITUTION:In a cyclone 3 for removal of dust from exhaust gas released from a melting-reducing furnace, for instance, a supply port 20a for charging impact particles 29 is provided in the almost intermediate stage position of a conical part 3b. When the impact particles 29 are charged into the cyclone 3 through the supply port 20a, the impact particles 29 hit the inner wall surface of the cyclone 3, while gyrating, to knock of accumulated material sticking to the wall surface and to drop it into the hopper 8, so that a connection with the hopper 8 is not clogged with the adhering accumulated material. As dust contained in the gas generated in the melting and reducing furnace sticks to the lower part of the conical section 3b concentratedly, the supply port 20a for the impact particles 29 is arranged at a point lower front the middle stage of the conical section 3b to assure secure removal of the accumulated material.

摘要： PURPOSE:To make it possible to prepare mixture with stable quality without fear such as dust explosion and the like due to fine dust-size particle by a method wherein granular mixture is produced by granulating slurry-like mixture into granules after being subjected to liquid extraction. CONSTITUTION:Slurry-like mixture, which is produced by mixing wiskers and matrix metal powder with organic solvent, is liquid extracted. After that, by adding with binder and kneading said mixture is granulated into granules having the diameter of about 0.5-1 mm so as to obtain granular mixture 2 by drying in order to feed to an injection molder 20 under vacuum atmosphere. The matrix metal is heated up to a temperature, at which both the solid phase and liquid phase of the metal are present each other, or higher in the gap between an injection cylinder barrel 11 and a screw rotor 12 of the molder. At the same time, the matrix metal is injection-molded from the injection nozzle of the molder into a mold so as to obtain a molded item with required shape. Further, in order to dry the granular mixture 2, the mixture is dried by being heated up to a temperature near the melting point of the matrix metal. Furthermore, after being injected in the mold, the matrix metal is compressed with the mold in order to obtain the molded item.

摘要： PURPOSE:To increase the reduction potential of a secondary combustion gas and making effective reutilization of the gas for preliminary reduction of iron ore by subjecting the gaseous CO generated at the time of supplying the iron ore subjected to the preliminary reduction in a preliminary reduction furnace to a melt reduction furnace and producing a molten iron to secondary combustion then supplying the same together with a reducing agent into a cyclone. CONSTITUTION:The powdery iron ore 3 and the CO-contg. gas formed by decreasing the temp. of the high-temp. reducing gas from a cyclone separator 13 to about 850 deg.C by utilizing the heat of a boiler are supplied to the preliminary reduction furnace 1 to preliminarily reduce the powdery iron ore. Such molten iron is then added into the melt reduction furnace 2. Pulverized coal 6 and oxygen 8 are supplied into the furnace 2 to thoroughly reduce the preliminarily reduced iron ore by heating and melting to form the molten iron. The CO in the reaction gas generated in this stage is burned by the oxygen 8 to increase the temp. of the molten iron and thereafter the CO is put together with hydrocarbon such as CH4 into the cyclone separator 13 to form CO+H2 and to restore the reduction potential; thereafter, the gas is utilized as the reducing gas to the furnace 1 via the boiler 18. The Fe-contg. dust emitted from the cyclone 13 is supplied to the furnace 2.

摘要： PURPOSE: To classify and recover heavy metals intended to be separated, classified and recovered as sulfides with high purity and high recovery rate always without increasing sulfur component content in treated waste water even when kinds and amounts of heavy metals in incineration ash which is the object to be classified and recovered vary from day to day. CONSTITUTION: A heavy metal solution in which the heavy metals in incineration ash are eluted is mixed with sodium sulfide, etc., and is pH-adjusted to precipitate and separate a part of the heavy metals as sulfides. After separation of precipitates, the solution is mixed with sodium sulfide, etc., again and is pH- adjusted to precipitate and separate a part or all of the heavy metals as sulfides. At this time, the amounts of the respective heavy metals in the heavy metal solution are obtained by analysis and the amounts of heavy metals to be precipitated and separated are previously calculated therefrom and amount of sodium sulfide, etc., to be added is set as amount of sulfer by making chemical equivalent of the amounts of the calculated heavy metals as a reference.

摘要： PURPOSE:To successively precipitate the lead and zinc in an incinerated ash as the sulfides and to fractionally recover the lead and zinc efficiently by supplying sodium sulfide to a soln. containing eluted heavy metals from the ash and regulating the pH of the soln. CONSTITUTION:The incinerated ash of refuse, etc., is mixed with hydrochloric acid to elute the heavy metals from the ash, and solid is separated from liq. to prepare the soln. of the heavy metals. Sodium sulfide or gaseous hydrogen sulfide is supplied while agitating the soln., and the pH is regulated to 0.4-1.2 to precipitate lead as the sulfide, which is separated and recovered. Sodium sulfide or gaseous hydrogen sulfide is then supplied to the soln. separated from the precipitate, and the pH is regulated to >=2 to precipitate the zinc as the sulfide, which is separated and recovered. Consequently, lead and zinc are fractionally separated from the incinerated ash efficiently, and the waste water generated in the recovery is made harmless.

摘要： PURPOSE:To improve the dephosphorizability and to relieve load in a dephosphorizing stage by specifying the concn. of C in molten pig iron and the temp. of the iron when the iron is discharged from an iron bath type melt reducing furnace. CONSTITUTION:Iron ore or prereduced iron ore and a carbonaceous substance are charged into an iron bath type melt reducing furnace in the form of briquettes, a slag forming agent is injected into the iron bath and oxygen is continuously blown to carry out the melt reduction of the iron ore. When the resulting molten pig iron is discharged, the concn. of C in the molten pig iron is regulated to >=3.5wt% and the discharge temp. is kept between a temp. higher than the liquidus line temp. of the composition of the molten pig iron by >=200 deg.C and 1,450 deg.C. Thus, a dephosphorization reaction during the melt reduction is allowed to proceed remarkably to relieve load in the following dephosphorizing stage.
