An device for manufacturing an active alloy includes: a melting chamber including: a working pipe surrounded by an induction coil and forming a working area; a chamber base disposed below the working pipe and communicated with the working pipe, and including: a gas inlet hole; a vacuum pump connection port; and a vacuum sensor, for measuring a vacuum degree in the working pipe; a chamber door communicated with the chamber base; a first bracket passing through the chamber base, and moving towards a direction away from or near the working area; a second bracket extending into the working pipe, and moving towards a direction away from or near the working area; and a material recycling seat which can extend into the chamber base in a push and pull way.

A device for melting a metal-containing mixture includes a vacuum melting furnace, in particular with a plasma jet melting means. A metal-containing mixture, in particular catalysts from motor vehicles, is to be fed into a graphite pool through a feed line. A first lateral discharge opening can be inserted into the graphite pool for discharging metal melt, and a second lateral discharge opening, specifically a siphon discharge opening, is provided for molten slags. The discharge openings are to be inserted through a wall of the graphite pool by a piercing lance. The lateral siphon discharge opening comprises an attached siphon with an integrated slag brick. An adaptively designed metal cover plate close to the outlet opening is inserted, in particular a copper cover plate, which is prepared in such a way that it is designed to be replaceable even when the vacuum melting furnace is running.

A strip casting system for aluminium and/or aluminium alloys comprising a casting furnace and a revolving chill mould having a casting gap. The revolving chill mould is designed as a roll pair, roller pair, caterpillar pair or belt pair. The strip casting system has an active means for transporting metal melt from the casting furnace to the casting gap and a casting region arranged in front of the casting gap. The casting region is delimited on one side by the revolving chill mould. A melt pool is formed in the casting region, from which metal melt flows or is drawn into the casting gap. The casting furnace is connected to the casting region by a pipe system with means for feeding the metal melt into the casting region, which can feed the metal melt to the casting region below the surface of the melt pool formed in the casting region.

An installation for recycling contaminated scrap metal includes a furnace frame and a melting furnace arranged within the furnace frame and configured to tilt, and a hood-like housing. The melting furnace includes an upper melting furnace opening and a casting device configured to cast a metal melt produced in the melting furnace into a pan. The hood-like housing is positioned on a top of the melting furnace and surrounds and covers the upper melting furnace opening. The hood-like housing includes at least one door, and a flue gas removal system coupled to the hood-like housing in a gas-tight manner and configured to tilt along with the melting furnace.

Described herein is a crucible with a rod fused thereon to optimize pouring of molten material, and method of using the same. The crucible has a body configured for receipt of an amorphous alloy material in a vertical direction, and the rod extends in a horizontal direction from the body. The body of the crucible and the rod are formed from silica or quartz. The rod may be fused to the body of the crucible and provided off a center axis so that pouring molten material is improved when the crucible is rotated.

The present invention addresses the problem of providing a heating furnace that sufficiently exhibits the microwave effect produced by microwave heating and allows economical heating taking advantage of the characteristics of each heating method. The provided microwave composite heating furnace (1) is equipped with: a housing (10); a heating container (11) for accommodating and heating an object to be heated; a heating means (12) for heating the heating container (11) from the outside; a microwave irradiation device (13); a to-be-heated object supplying device (14) that supplies the object to be heated to the inside of the heating container (11); a gas introducing means (15) for introducing gas into the heating container (11); and a gas recovery means (16) for recovering the gas generated when heating the object to be heated. The heating container (11) comprises a material that has high electrical conductivity so as to reflect microwaves and confine the microwaves inside and that has high heat resistance so as not to react with the heated object, thereby confining microwaves irradiated into the heating container (11) not through the outer wall of the heating container, and allowing an improvement in electromagnetic field density.
