A crucible assembly is suited for use melting aluminum cans at a campfire or similar fire. The crucible assembly may include a handle design that facilitates safe and easy handling of the crucible after it has been heated and contains melted aluminum. The crucible assembly may also include a portion having a convex surface that maintains contact with the ground during rotation of the crucible, thereby providing support and stability to the crucible as melted aluminum is poured therefrom.

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.

A mobile melting device for consolidating contaminated scrap and to a corresponding method. The melting device has a crucible chamber and a crucible base. The crucible is arranged on the crucible base during operation, and the crucible base and the crucible chamber together form a gas-tight furnace housing. It is thus possible to carry out the method in a vacuum or under protective gas such that even a reactive material can be consolidated. The melting device can be assembled and disassembled with little effort.

A heating device with a heat conducting element and an evaporation system using the same are provided. The heating device includes a crucible, a heat conducting element and a heating element. The crucible includes a bottom surface, an opening opposite to the bottom surface and an accommodation space for accommodating a to-be-evaporated material. The heat conducting element is disposed in the accommodation space of the crucible and disposed on the bottom surface and extending towards the opening. The heating element is disposed adjacent to the crucible.

An example mobile kiln system includes a mobile platform. A frame is mounted to the mobile platform. At least one kiln is rotatably mounted to the frame. The kiln is movable between a first operational position for loading a feed material into the at least one kiln, and a second operational position for unloading a biochar product from the at least one kiln following processing of the feed material. In an example, the mobile kiln system includes at least one stack assembly for the kiln. The stack assembly has a lid to cover the kiln to retain heat and a chimney to release emissions from the kiln during processing of the feed material.

The present invention relates to an electric arc furnace, containing a furnace shell, an electrode, a furnace shell moving mechanism that supports the furnace shell so as to be movable on an installation surface, and a first insulation that electrically insulates between the furnace shell and the furnace shell moving mechanism.

A crucible used for forming ceramic particles from metal oxide gel particles includes a tubular graphite housing having an open end, an inner surface, and a seat in the inner surface near the open end. A sleeve lines the inner surface of the tubular housing. The sleeve has at an open end and is formed from a metal which is chemically inert to the metal oxide gel particles. A graphite outer cap removably covers the open end of the tubular housing. An inner cap formed from the chemically inert metal fits into the seat in the inner surface of the tubular housing, and is pressed into the seat against the open end of the sleeve by the outer cap. The crucible may be used for forming ceramic particles from uranium oxide gel particles, and the sleeve and the inner cap may be formed from molybdenum, tungsten, or an alloy thereof.

A melting furnace is provided, that may contain a furnace shell, a furnace shell moving mechanism that supports the furnace shell so as to be movable on an installation surface, a pipe or a wiring that has one end fixed to the furnace shell and has at least partially, a flexible portion, and a stand. The stand may contain a supporting part that supports a halfway portion of the pipe or the wiring, and a stand moving part that is coupled to the supporting part and moves the supporting part on an installation surface in synchronization with movement of the furnace shell, in which the stand is mounted on the installation surface so as to be movable up and down with respect to the furnace shell.
