  • Patent number: 6523721
    Abstract: A granular material supply system has a granular material supply unit and a granular material feed unit. The granular material supply unit delivers a granular material through an inlet formed in a pressure case included in the granular material feed unit onto a conveying device disposed in the pressure case. The conveying device conveys the granular material to an outlet formed in the pressure case to feed the granular material through the outlet into a granular material using apparatus. The granular material supply unit, and the pressure case of the granular material feed unit can be immovably installed. Therefore the granular material supply system can be formed in a closed system without placing any special joints, such as expansion joints, in a line connecting the granular material supply unit and the pressure case and in a line connecting the pressure case and the granular material using apparatus. Only the conveying device needs to be disposed in the pressure case.

  • Patent number: 6506007
    Abstract: A fastening bolt fastens flanges between a bolt head and a nut attached on the threaded portion of the shaft via spherical washers. The fastening bolt has a cavity formed within the shaft. By application of pressure in the cavity with a hydraulic fluid supplied through a hydraulic pressure port in a plug, the shaft is extended and the fastening bolt becomes unfastened condition. In the unfastened condition, a gap is created between flange and nut, and the nut and the fastening bolt are free to rotate each other, therefore, the nut can be removed easily by hand from the fastening bolt, even the bolt is large in size. The fastening force is adjustable by the width of the gap before releasing hydraulic pressure in the cavity. By releasing hydraulic pressure in the cavity, the fastened condition is obtained. Conversion between fastened condition and unfastened condition can be made quickly and easily.

  • Patent number: 5246482
    Abstract: The disclosure relates to a molten metal producing and refining method which does not damage the apparatus, realizes a stable and high second combustion rate, and is capable of effectively recovering heat generated by the second combustion. The method comprises introducing a metal-containing material, a carbonaceous material, a flux and O.sub.2 gas into a furnace. The carbon which dissolves into the metal bath in the furnace from the carbonaceous material is combusted with the O.sub.2 gas to generate heat and CO gas. The CO gas is subjected to the second combustion with the O.sub.2 gas to additionally generate heat, and the metal-containing material is melted and refined by both the generated heat and carbon. The method is characterized in that O.sub.2 gas or O.sub.2 -containing gas is blown into the furnace through large-diameter tuyeres installed near the bottom of the furnace and a part of the O.sub.

  • Patent number: 4940488
    Abstract: Metal oxide ore is subjected to smelting reduction to obtain the molten metal by a method which comprises prereducing said ore in solid state in a prereduction furnace, thereafter melting said ore and carrying out final reduction thereof in a smelting reduction furnace, and at the same time introducing gas generated in said smelting reduction furnace and having reductive capability into said prereduction furnace, the rate of prereducing said ore in said prereduction furnace being controlled at a value with a maximum of the order of 33 percent for raising the rate of utilization of energy to a maximum limit.

  • Patent number: 4886246
    Abstract: A metal-making apparatus is suited for the production of molten iron from iron ore which is in a state of particles with a wide range in size. Included are a solid-state prereduction furnace for preliminarily reducing the raw ore particles in a solid state, and a smelting reduction furnace for smelting the prereduced ore particles and reducing them in a molten state. High temperature reducing gas generated within the smelting reduction furnace is directed into the prereduction furnace and blown up through a distributor on which there is loaded a charge of raw ore particles. The ore particles of larger size form a fluidized bed on the distributor and so are prereduced by making intimate contact with the gas. Ore particles of smaller size, on the other hand, are carried away from the fluidized bed by the waste gas and thereby prereduced while being recirculated through the prereduction furnace.

  • Patent number: 4462793
    Abstract: This disclosure relates to a rotary kiln for heating and calcining lime, waste, etc. and to a method of direct reduction of metal oxide using such a kiln. A cylindrical outer shell is mounted for rotation on its axis, and a stationary inner tube extends into the interior of the shell. Fuel and/or combustion air flow passages extend within the tube, and burner nozzles are supported by the tube and are connected to the passages. The tube is concentrically or eccentrically mounted adjacent the upper side of the space within the shell, thereby positioning the burner nozzles at the optimum positions.

  • Patent number: 4348225
    Abstract: Static bed type iron oxide reducing apparatus comprises reduction furnaces and cooling chambers respectively associated with the furnaces. Iron oxides are charged into the furnaces and reducing gas is applied to the raw materials to carry out a reducing reaction. After the iron oxides in the furnace have been metallized to a sufficient level, they are transferred to the cooling chamber to be cooled therein.
