摘要： PURPOSE:To treat zinc plated steel plate scraps to those suited for raw materials for cast iron by heating said scraps to temps. around the b.p. of zinc, thereby evaporating the plated zinc and separating the same from the scraps. CONSTITUTION:Zinc plated steel plate scraps are supplied from the upper part of the cylinder of a rotary kiln, and are heated with gas burners from the lower part. When the inside of the cylindr is heated to 907 deg.C which is the b.p. of zinc or temps. above this, the plated zinc evaporates and the gas thereof is forced upward by the combustion gas of the burners, and is discharged to the outside of the cylinder. The steel plate scraps removed of the zinc plating are transferred downward in the cylinder and are removed from the bottom end.

摘要： PURPOSE: To make the highest possible utilization of the space possible in a tray by interposing thin films between the green compacts to be arrayed in the tray and sintered.
CONSTITUTION: In arraying circular cylindrical green compacts 1 on a tray 2, paper 3 as a thin film is inserted between each row in a transverse (lateral) direction, and the green compacts 1 of the adjacent rows adjoin to each other via the paper 3 with a shift corresponding to the half diameter thereof. The adjacent green compacts in the same row are arranged to the extent of contacting with each other lightly. Such green compacts are fed in a longitudinal (vertical) direction, and are sintered in a nonoxidative atmosphere of endothermic gas or gaseous ammonia. In this case, the paper 3 carbonizes but remains in the form of thin films and therefore the binding between the powder moldings of the adjacent rows is prevented. The powder moldings in the same row are bound in one row and since bound points 4 are two points at most, they can be easily parted by a small force. Since the feeding into the furnace is performed in the longitudinal direction of the row, there is no possibility of causing sticking at points 4.

摘要翻译：目的：通过在要排列在托盘中的生坯和介质之间插入薄膜，尽可能最大限度地利用托盘中的空间。构成：在托盘2上排列圆柱形绿色压块1时，作为薄膜的纸3以横向（横向）方向插入每排之间，并且相邻行的生坯1经由纸3彼此相邻其移位对应于其半径。相邻行的相邻的绿色压块被布置成彼此轻微接触的程度。这种生坯在纵向（垂直）方向上进料，并在吸热气体或气态氨的非氧化气氛中烧结。在这种情况下，纸3碳化，但保持为薄膜的形式，因此防止相邻行的粉末成型品之间的结合。同一行中的粉末成型品一行结合在一起，由于结合点4最多为两点，因此它们很容易被小力分开。由于沿排的长度方向进入炉内，所以不可能在点4处发生粘附。

摘要： PURPOSE: To obtain the titled casting under a so called as-cated condition without performing any heat treatment after casting, by forming a thickness so that is will be cooled at a cooling rate which is faster than a prescribed one, and, at the same time, by performing the casting so that chemical elements other than Fe and impurities may be specified.
CONSTITUTION: A casting composed of 3.5W4.2% C, 2.0W3.3% Si, ≤1% Mn, 0.03W0.20% Sn, 0.02W0.06% Mg, and the rest of Fe and impurities, is manufactured by the following method. That is to say, when the casting is formed so that is may have the above mentioned chemical composition, and when the thickness is formed so that the casting may have ≥13/sec cooling rate, a spheroidal graphite cast iron casting having 50W90% pearlite ratio may stably be obtained even under an as-coated condition. As the result of this, small parts for automobile, etc., can be manufactured under an excellent working environment and any energy saving condition.

摘要： PURPOSE:To enable casting wherein greensand is used, by fixing four flasks to a rotary disk on the same periphery at equal intervals, by setting a greensand feeding, a molding, a pouring, and a mold balance station successively corresponding to those flasks, and by circulating through those four stations. CONSTITUTION:Greensand is introduced in a flask 8 placed in a greensand station A. A rotary disc 7 is rotated, the flask 8 is placed in a molding station B, air cylinder 9 is worked, a piston rod is dropped through a beam 10 to push down into greensand which filled a pattern 11. The pattern 11 is drawn out with the air cylinder 9 to prepare a mold. Then the flask 8 with the prepared mold is rotated by 90 deg. and is placed in a casting station C to introduce the ductile molten metal. The filled flask 8 is rotated by 90 deg. and is placed in a mold-balance station D. The air cylinder 9 is worked and a pushing-out member 13 is dropped down. The mold is collapsed and the round bar for examination is removed.

摘要： PURPOSE:To borm a suitable amount of working coating to the product part of the metallic mold and planning part by coating soot, by ascending and descending a burner provided opposing to the surface of metallic mold in the open state when a turntable is stopped during charging molten metal. CONSTITUTION:A prescribed number of fixed members 2 are fixed with equal pitch to the outer circumference of a turn table 1, each of them facing to a rotating center shaft. Next, facing to each member 2, a movable metallic molds 3 are set reciprocally movable in the radial direction of the table 1 so that it moves once back and forth while the table 1 rotates its full turn. When the butting surfaces of the molds 2 and 3 are allowed to contact with each other and become docking state, the table is stopped to rotate and molten metal is charged to the molds 2, 3. After the completion of charging, the table begins to ratate, and releasing taking-out of products and cleaning operations are made during the rotation. When the mold 2, 3 stops in the facing position of a burner 4, the burner begins to go down from its upper stand-by position and acetylene gas spouted from a nozzle 4c is ignited. Thus produced soot is coated on the surface of the molds 2, 3. After the coating is over, the burner 4 is lifted to its stand-by position and is extinguished.

摘要： PURPOSE:To prevent occurrence of misrun and defective degassing at thin parts and acute-angled parts and obtain cast products of excellent quality by vibrating the mold in casting molten metal. CONSTITUTION:The molding flask 1 filled with the mold M is placed on the sand 3 in the sand box 2 and the sand box 2 is set on the vibration plate 3. The molten metal is poured into the mold M and vibrator 6 is vibrated. The vibration is cushioned by the charcoal e in the sand box 2 and transmitted to the molding flask 1. Consequently, the vibration is transmitted also to the molten metal in the mold M to promote fluidity and degassing action. The frequency and amplitude of vibration are adjusted by the control panel 7 according to the quality of molten metal and shape of the mold M. At the same time, proper selection is made for the nature of the vibration, vertical, horizontal or combination of the two. Thus, the run at thin parts is improved, degassing in solidification of the molten metal is bettered, and cast products of good quality can be obtained.
