A method of manufacturing a sensor set-up for determining at least one pressure of a fluid medium. The method includes: a) providing a blank of a sensor set-up including at least one pressure connection, the pressure connection including at least one pressure deformation element made up of at least one material suitable for induction; b) positioning at least one glass element onto a surface of the pressure deformation element; c) measuring at least one temperature of the pressure deformation element using at least one pyrometer; d) inducing a voltage in the pressure deformation element using at least one inductor in such a manner, that the glass element melts and a glass layer forms on the pressure deformation element; e) positioning a sensor element onto the glass layer in such a manner, that an integral bond forms between the sensor element and the glass layer.

Various embodiments provide an apparatus and methods for containing the molten materials within a melt zone during melting. The apparatus may include a vessel configured to receive a material for melting therein and an induction coil with unevenly spaced turns along its length. Induction coil can have a series of turns acting as a first (e.g., load) induction coil and a series of turns acting as a second (e.g., containment) induction coil. The material in the vessel can be heated and contained by the separated turns of the induction coil. A plunger can also assist in containing material during melting. Once the desired temperature is achieved and maintained for the molten material, operation of the induction coil can be stopped and the molten material can be ejected from the vessel into a mold using the plunger.

Disclosed herein is a method comprising disposing a container containing a metal and/or ferromagnetic solid and abrasive particles in a static magnetic field; where the container is surrounded by an induction coil; activating the induction coil with an electrical current, to heat up the metallic or ferromagnetic solid to form a fluid; generating sonic energy to produce acoustic cavitation and abrasion between the abrasive particles and the container; and producing nanoparticles that comprise elements from the container, the metal and/or the ferromagnetic solid and the abrasive particles. Disclosed herein too is a composition comprising first metal or a first ceramic; and particles comprising carbides and/or nitrides dispersed therein. Disclosed herein too is a composition comprising nanoparticles comprising chromium carbide, iron carbide, nickel carbide, y.-Fe and magnesium nitride.

Vessels used for melting material to be injection molded to form a part are described. One vessel has a body formed from a plurality of elongate segments configured to be electrically isolated from each other and with a melting portion for melting meltable material therein. Material can be provided between adjacent segments. An induction coil can be used to melt the material in the body. Other vessels have a body with an embedded induction coil therein. The embedded coil can be configured to surround the melting portion, or can be positioned below and/or adjacent the melting portion, so that meltable material is melted. The vessels can be used to melt amorphous alloys, for example.

A method of cooling an electric induction furnace for melting and holding a reactive metal or alloy is provided where the electric induction furnace has an upper furnace vessel and an induction coil in a modular inductor furnace is positioned below the upper furnace vessel with a melt-containing vessel positioned inside the induction coil with a gap between the outside surface of the melt-containing vessel and the inside surface of the induction coil that is used to circulate a cooling fluid for cooling the melt-containing vessel to inhibit leakage of the reactive metal or alloy melt from the melt-containing vessel. The melt-containing vessel can be integrated with a cooling system for cooling the melt-containing vessel. Modularity of the melt-containing vessel, induction coil and cooling system facilitates servicing of the modular inductor furnace without disassembly of the entire electric induction furnace.

An adjustable head system of an induction furnace and method of use thereof. The adjustable head system includes a head, an apron that operably engages with an outer shell of the induction furnace, and at least one head drive assembly that operably engages with the apron. The at least one head drive assembly is configured to automatically adjust the head along an axis angled relative to the apron upon assembly of the induction furnace, upon disassembly of the induction furnace, or during a melting operation of the induction furnace.

Embodiments concern a plant for melting and/or heating metal material and a corresponding method to supply electrical energy. The plant comprises at least one induction furnace (11) and means (12) for supplying electrical energy to the induction furnace 11), wherein the electric power supply means (12) comprise at least one transformer (13) connected to an alternating current mains power network (14), at least one rectifier (15) located downstream of the transformer (13), at least one converter (16) located downstream of the rectifier device (15), and at least one coil (17) for melting and/or heating metal material.

The present disclosure discloses a magnetic device for induction heating thereof that relates to the field of induction heating technologies. The magnetic device includes at least four coils that are even numbers, wherein the at least four coils are equally divided into two groups, and the two groups of coils are symmetrically arranged around an axis thereof; and a driving unit arranged on a symmetrical central axis of the coil and configured to drive a metal material to be heated to rotate. The present disclosure provides the even number of coils combined to form an annular coil device, so that a larger and more uniform magnetic field is generated in a center of the annular coil device, which can be more favorable for improving an eddy current heating effect thereof.
