A method and an apparatus for continuously manufacturing non-fired pellets, which comprise: continuously supplying green pellets containing a carbonating binder into a vertical type reactor to continuously pass the green pellets sequentially through a predrying zone, a carbonating zone and a drying zone in the vertical type reactor; blowing a predrying gas having a relative humidity of up to 70% and a temperature of from 40.degree. to 250.degree. C. into the predrying zone to predry the green pellets therein until the water content of the green pellets in the predyring zone falls within the range of from 1 to 7 wt. %; blowing a carbonating gas comprising carbon dioxide gas of from 5 to 95 vol. % and saturated steam of from 5 to 95 vol. % and having a temperature of from 30.degree. to 98.degree. C. into the carbonating zone to carbonate the carbonating binder contained in the green pellets therein; and blowing a drying gas at a temperature of from 100.degree. to 300.degree. C. into the drying zone to harden the green pellets therein, thereby continuously manufacturing non-fired pellets.

An object is to provide a mobile electronic device and an input method that can display soft keys corresponding to each of the characters of different character kinds appropriately even in a state where the display screen of the display unit is used horizontally. In a state where the display screen is used vertically, the control unit splits the display screen into upper and lower sides and displays the plurality of soft keys in the display screen uniformly. In a state where the display screen is used horizontally, the control unit splits the display screen into right and left sides, and displays the first character kind character on one side, and displays the second character kind character on the other side, and displays a plurality of soft keys on either one of the one side or the other side in a right-left direction.

A mobile electronic device includes a first touch sensor on a first face of a housing, a second touch sensor on a second face of the housing different from the first face, a display unit provided on the first face of the housing, and a control unit. When a first touch on the first face is detected by the first touch sensor and a second touch on the second face is detected by the second touch sensor, the control unit selects an object displayed on the display unit based on the first touch on the first face and the second touch on the second face.
摘要:
The invention is concerned with the method of compression molding a metallic or ceramic powders. The method includes the step of maintaining a negative pressure within a first mold of noncompactable powders for intimately contacting on its inner surface a pouch-like member of thin-walled resilient material for producing a second mold, and the step of compactly charging starting powders into the second mold and exhausting air from and sealing the second mold, taking out a pre-molded body of the metallis or ceramic powders together with the second mold and the step of processing the pre-molded body by a cold or hot isostatic press.
摘要:
In a method of producing unbaked agglomerates, green pellets or briquettes are produced by adding 5 to 30% of reduced iron powder, mill scale powder or iron sand and also adding a binder consisting of a cement or granulated blast furnace slag and then the green pellets or briquettes are dry cured thereby producing agglomerates having excellent reducing performance.
摘要:
A device for making high temperature reformed gas from coke oven gas and blast furnace gas comprises a continuous heating apparatus for preheating a coke oven gas; and a first system including (a) an intermittent heat exchanger containing therein a packing bed of the heat-accumulator type for preheating a blast furnace gas; (b) a separate cyclone-type gas mixing chamber for mixing the preheated raw gases; and (c) an intermittent reforming furnace containing therein a packing bed of the heat-accumulator type impregnated with a catalyst. A second system comprising counterpart elements (a), (b) and (c) is connected to the apparatus (a) in parallel with the first system so as to be operated alternately with said first system. Bypass valves are preferably provided to feed the blast furnace gas directly to the gas mixing chamber bypassing the intermittent heat exchanger.
摘要:
There is provided a method of blast furnace operation utilizing selective recycling of peripheral gas stream wherein the number of outlet ports for peripheral gas stream and the position of the gas outlet ports relative to the inlet ports for reducing gas are optimalized and the content of nitrogen in the recycling gas and the content of nitrogen in the reducing gas to be injected are controlled within the respective predetermined ranges.
