A method for making Mg brass EDM wire has the steps of melting a charge of Mg brass to form a melt of Mg brass; transferring the melt to a holding furnace; casting a rod from the melt; and drawing the rod down to a size suitable for EDM machining. Mg deposits may form in the holding furnace. These can be removed by flushing the holding furnace with molten brass.

This copper alloy wire is a copper alloy wire which is made of a precipitation hardening-type copper alloy containing Co, P, and Sn and is manufactured using a continuous cast-rolling method or cold working of a continuous cast wire rod manufactured using a continuous casting method, in which the copper alloy wire has a composition including Co: more than or equal to 0.20 mass % and less than or equal to 0.35 mass %, P: more than 0.095 mass % and less than or equal to 0.15 mass %, and Sn: more than or equal to 0.01 mass % and less than or equal to 0.5 mass % with a balance being Cu and inevitable impurities.

In a method for forming a shape memory alloy wire a shape memory alloy composition of CuAlMnNi excluding grain refiner elements, is mixed, including between about 20 at % and about 28 at % Al, between about 2 at % and about 4 at % Ni, between about 3 at % and about 5 at % Mn, and Cu as a remaining balance. The mixture is heated between about 1100 C. and about 1400 C. and ejected from a crucible, at an ejection pressure of between about 3 bar and about 5 bar through a nozzle having a nozzle diameter of between about 200 microns and about 280 microns, to a face of a melt spinning wheel with speed of between about 9 m/s and about 13 m/s until there is formed a shape memory alloy wire having a length of at least about 1.5 meters and a diameter of no more than about 150 microns.

The disclosure relates to a method for operating a cooling chamber in a strand guide device and the strand guide device 10 as such. The strand guide device serves to deflect a freshly cast strand, typically made of metal, into the horizontal. During the deflection, the cast strand passes through a cooling chamber 1 inside the strand guide device 2, in which it is sprayed with a coolant 33, with the formation of steam 5. The steam forms at least a steam-air mixture 5 with sucked-in secondary air, which is sucked out of the cooling chamber by a suction device 20. In particular, in order to reduce the pollutant content of the sucked-in and sucked-off steam-air mixture 5 and its emission into the environment, the present invention provides for pollutants, primarily dust, located in the steam-air mixture 5 by a separator 6, 6 to deplete.

This continuous cast wire rod contains Cu: 62.0 mass % or greater and 70.0 mass % or less, Sn: 0.3 mass % or greater and 0.9 mass % or less, Zr: 0.0050 mass % or greater and 0.1000 mass % or less, and P: 0.0050 mass % or greater and 0.1000 mass % or less, with a balance being Zn and impurities, and a mass ratio Zr/P of Zr to P is 0.3 or greater.

The present invention relates to a composite material based on aluminium and alumina, its method of manufacture, and a cable comprising said composite material as an electrical conductor element.

A roll for continuous casting comprises a cylindrical roll rotatably mounted on a fixed axle and said axle comprising a coolant inlet system and a coolant outlet system. A cooling chamber receives a flow of coolant. The coolant chamber is defined by the space between the interior of the cylindrical roll and the axle. At least one spiral is formed onto the axle that creates a helical flow path from the coolant inlet system to the coolant outlet system.

A copper alloy wire and a manufacturing method thereof are provided. The copper alloy wire includes: by weight percentage of components, 0.3 to 0.45 of silver (Ag), 0.01 to 0.02 of titanium, and a remaining part that is formed by copper and unavoidable impurities. The method for manufacturing the copper alloy wire is performing two-phase vacuum melting: first performing vacuum electric arc melting into a copper-titanium mother alloy, and then performing vacuum induction melting with remaining components into a copper alloy wire material by means of continuous casting; then drawing the copper alloy wire material into a copper alloy fine wire by a non-slip wire drawing device in a material even-flow wire drawing manner, and finally performing thermal treatment on the copper alloy fine wire by using argon as a protection gas, so as to complete a process of the copper alloy wire.
