A sidewall for a metallurgical furnace and a metallurgical furnace having the same are described herein. In one example, a sidewall of a metallurgical furnace is provided that includes an outer wall, a hot plate and a buckstay. The hot plate is coupled in a spaced apart relation to the outer wall. The buckstay is mechanically coupled to the outer wall and the hot plate. The buckstay includes a buckstay web extending from a buckstay flange. The buckstay web includes a first end coupled to the buckstay flange, and a second end mechanically and movably coupled to the hot plate.

The present invention provides a high temperature vacuum furnace that includes a prefabricated solid tongue-and-groove HEFVAC insulation ring assembly hot zone with significantly reduced overall mass, resulting in increased energy efficiency, faster heating and cooling cycles, reduced electricity costs, and expedited maintenance capability thus resulting in lower maintenance costs. The present design eliminates the prior art heavy, fully enclosed metal support ring designed to ensure retention of the insulation shield packages, including all retainer pins and nozzles in place during the heating and high pressure gas quenching cycles, found in prior art vacuum furnaces. The prior art metal support ring is replaced with a bottom support structure whose mass is approximately 80-85% less than the mass of the old support ring. Reducing the mass within the furnace chamber reduces the time and energy it takes to heat and cool the furnace components and the workload being heat treated. Decreased time in the furnace improves production turnaround and lowers energy costs for each heat treating cycle. In one embodiment the prefabricated HEFVAC insulation assembly outer surface contains a very thin stainless steel sheet of approximately 0.030 inches thick, which acts as a low emissivity reflective shield between the prefabricated insulation board ring assembly and the outer water-cooled furnace chamber wall. In another embodiment the prefabricated HEFVAC insulation assembly has no stainless steel sheet on its outside surface adjacent to the furnace plenum and the outer water-cooled furnace chamber wall. The present furnace is easier and less expensive to manufacture compared to prior art vacuum furnaces, and requires less energy to operate.

A refractory unit for lining a high temperature vessel includes a refractory body formed from a refractory material. The refractory body has an upper main surface, a lower main surface, an inner surface configurable to face a high temperature chamber, an outer surface configurable to face away from the high temperature chamber, a first side surface and a second side surface. An elastic member is attached to the outer surface.

A modular structure wall of a high-temperature heating furnace including furnace wall main trusses and a furnace roof truss. Connecting I-beams are fixed on the bottom surface of the furnace roof truss, top clamping structures of hoisting outer screws are hooked with the bottoms of the connecting I-beams, the upper surfaces of ceramic fiber cotton modules are uniformly distributed with upwardly convex hoisting outer screws, and the ceramic fiber cotton modules are installed on the lower surface of the furnace roof truss through the hoisting outer screws. A gap is formed between the ceramic fiber cotton modules and the lower surfaces of the connecting I-beams, a ceramic fiber cotton felt is laid in the gap area between the ceramic fiber cotton modules and the lower surfaces of the connecting I-beams, and a furnace wall inner protective lining is fixedly installed on the lower surfaces of the ceramic fiber cotton modules.

A shielding module for a high-temperature furnace has a packet of interconnected shielding plates. The packet of interconnected shielding plates is mounted to a common base body. The base body has fixing points for fixing to base bodies of other shielding modules of the same kind.

A hold down mechanism for releasably securing a refractory lining to a furnace. The hold down mechanism can comprise plate segments that form a composite plate. The plate segments can comprise a first plate segment structured to articulate relative to a second plate segment. Furthermore, a gap in the hold down mechanism can be structured to adjust in response to a thermal condition of the composite plate, such as thermal expansion or thermal contraction of at least one plate segment. The composite plate can also comprise an articulation plate pivotally coupled to at least one of the first plate segment and the second plate segment via a pivot and/or a slot and pin engagement. The composite plate can further comprise a third plate segment and a second articulation plate pivotally coupled to at least one of the second plate segment and the third plate segment.

Provided is a vacuum beat insulation structure for a heating furnace having a beating space covered by an inner cylinder serving as an inner wall, and an outer cylinder serving as an outer wall configured to cover the inner cylinder, and a vacuum space formed between the inner cylinder and the outer cylinder, the vacuum heat insulation structure including a reflective film disposed in the vacuum space and configured to prevent transfer of radiant heat from the inner cylinder to the outer cylinder in the vacuum space, and a fixing tool configured to fix the reflective film to an inner surface of the outer cylinder so as not to come in contact with an outer surface of the inner cylinder.
