Abstract: The present invention relates to a method for preparing a recycled low-nickel magnesium alloy using magnesium scraps. More particularly, the recycled magnesium alloy having a reduced nickel content can be prepared by adding Al and misch metal to molten magnesium scraps so as to form an Ni—Al-misch metal three-phase alloy or cluster thereof; and separating and removing the formed Ni—Al-misch metal three-phase alloy or the cluster thereof using gravity.

Abstract: A magnesium-alloy plate manufactured by completely melting a magnesium-alloy material received in a hermetic type melting furnace; transferring the molten magnesium-alloy into a hermetic type heat insulation furnace through a hermetic type transfer runner; discharging the molten magnesium-alloy received in the heat insulation furnace into a recessed portion of a casting wheel through a casting runner, to which a mixed gas containing SF6 is injected by ignition-suppression gas injection tubes; and continuously casting the molten magnesium-alloy entered into the recessed portion of the casting wheel into a magnesium-alloy plate using a casting band circulating around the casting wheel while coming into contact with an upper portion of the recessed portion.

Abstract: The present invention relates to a non-combustible magnesium alloy, comprising one of elements of Al at 0.1˜3 wt %, La at 0.1˜3 wt %, Nd at 0.1˜3 wt %, or Y at 0.005˜3 wt %; 0.5˜10 wt % of Ca; and the remainder of conventional magnesium alloy. Alternatively, the present invention entails a non-combustible magnesium alloy comprising 0.005˜4 wt % of multiple additives of two or more types of elements selected from the group consisting of Al, La, Nd and Y; 0.5˜10 wt % of Ca; and the remainder of conventional magnesium alloy. The magnesium alloy of the present invention has high oxidation-resistance, which translates into high manufacturability in air or in the generally non-oxidative atmosphere (SO2, Ar, CO2, N2).

Abstract: The present invention relates to an apparatus for producing a honeycomb body, which comprises a roll part for supplying a thin metal flat sheet via several rolls; a part for measuring the length of feed of the flat sheet which is fed through said roll part for supplying a flat sheet; a roll part for supplying a corrugated sheet to overlap the same onto said flat sheet via several rolls; a winding roll of a honeycomb body which is made by folding the overlapping flat and corrugated sheets in feed into a roll; a part for measuring the rotation angle of said winding roll; and a control part, which is connected respectively to said part for measuring the length and said part for measuring the rotation angle, wherein said control part controls the amount of winding of a honeycomb body by receiving and computing the measurement values therefrom.

Abstract: The present invention relates to an apparatus for mass production of metal substrates used in catalytic purification of exhaust gas, which includes: (a) an uncoiler part for continuously feeding a strip in the lengthwise direction, wherein said strip is coiled along a rotation axis; (b) a tubing processing part for changing the strip into the shape of a pipe by means of gradually putting pressure through multi-stage rolls onto both side edges of the strip in feed from said uncoiler part; (c) a feeder part, which is installed at one side of said tubing processing part, for feeding a pre-made honeycomb body at an equal interval to the strip being changed into the shape of a pipe; (d) a welding part, which is installed at the rear end of said tubing processing part, for welding into a unit both side edges of the strip in feed after being changed into the shape of a pipe; (e) a sizing part, which is installed at the rear end of said welding part, for evening the girth of the pipe in feed; and (f) a cutting part f

Abstract: The present invention relates to a one-body continuous casting apparatus for fabricating a rod or slab shape of phosphorized copper by means of using a horizontal continuous casting process. Such invention contemplates designing and manufacturing a one-body melting and casting machine using high or low frequency induction heating, wherein a molten metal is deoxidized and refined in the system which comprises installing the multistage graphite filters inside the melting and casting machine, so the procedure of transferring the molten metal from the melting furnace to the casting machine can be eliminated, thereby enabling the horizontal continuous casting apparatus to manufacture a phosphorized copper of high quality.
