摘要： A wafer boat handling device, configured to be positioned under a process chamber of a vertical batch furnace. The wafer boat handling device comprises a main housing having a wall defining and bounding a wafer boat handling space, and a boat transporter comprising a wafer boat support for supporting a wafer boat and configured to transport the wafer boat to a cooldown position within the wafer boat handling space. A part of the wall adjacent the cooldown position is a wall part with a heat radiation surface absorptance of at least 0.60 so as to withdraw heat from the wafer boat which is in the cooldown position by means of heat radiation absorption.

摘要： 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.

摘要： The heat treatment method of the present invention includes: a first step of mist cooling a treatment object retained at a prescribed temperature by supplying mist-like coolant, to a target temperature near to and higher than a first transformation point at which a structure of the treatment object begins to be transformed into a prescribed structure; a second step, following the first step, of retaining the treatment object for a prescribed time in a state where supply of mist-like coolant is stopped; and a third step, following the second step, of cooling the treatment object to a temperature lower than or equal to the first transformation point. According to the present invention, it is possible to provide a heat treatment method capable of suppressing irregularity and deformation in the structure of the treatment object.

摘要： Cylindrical carbon blanks are assembled into one or more upright stacks which are advanced stepwise in an upward direction in one or more upright tubes which insulate the column or columns from the surrounding atmosphere. The blanks in the upright tube or tubes are preheated by exchanging heat with an inert gas, such as pure argon, and the preheated blanks are thereupon conveyed along one or more horizontal path sections into the upper end of an additional tube wherein the blanks are heated to graphitizing temperature by a series of electrode pairs. The thus obtained graphite electrodes are cooled by inert gas which is thereupon admitted into the upright tube or tubes to preheat fresh carbon blanks.

摘要： The present disclosure relates to a decarbonation process of carbonated materials, in particular limestone and dolomitic limestone, with CO2 recovery in a multi-shaft vertical kiln (MSVK) comprising a first and a second shaft with preheating, heating and cooling zones and a cross-over channel between each shaft. The method includes alternately heating carbonated materials by a combustion of at least one fuel with at least one comburent, up to a temperature range in which carbon dioxide of the carbonated materials is released, the combustion of the fuel and the decarbonation generating an exhaust gas. Decarbonated materials are cooled in the cooling zones with one or more cooling streams. The process further includes extracting the exhaust gas from the multi-shaft vertical kiln and feeding a buffer with the extracted exhaust gas.

摘要： The invention relates to equipment for cooling a metal strip (2) having a liquid coating to be solidified, wherein said strip is continuously moving. Said equipment is characterized in that each half-cooler (11, 12) is divided, over the length thereof, into at least two sections, a first section (13) and a second section (14), in the direction of the movement of the strip (2). The first section (13) is separated from the second section (14) in each half-cooler (11, 12) by a respective internal adjustment device (7, 8), making it possible to change the gas flow/pressure parameter so that the value of said gas flow/pressure parameter is different in the first section (13) from the value of said parameter in the second section (14).

摘要： The invention relates to a method of improving the cooling of a blown-gas cooling chamber or of a blown-air cooling section in a line for heat treating steel and/or aluminum, and/or of improving the quality of products for treatment by reducing the vibration generated by the cooling, in which jets of gas or air are projected against each of the faces of the strip traveling through said section or chamber. In accordance with the invention, the jets (58) of gas or air are emitted from blow tubes (52) fitted to tubular nozzles (51) arranged at a distance transversely on either side of the travel direction (100) of the strip (53), said jets being directed towards the corresponding face of the strip while being inclined simultaneously essentially towards the edges of said strip in a plane perpendicular to the panel of the strip and to the travel direction (100) of said strip, and towards the upstream or downstream end of the strip in a plane perpendicular to the plane of the strip and parallel to the travel direction (100) of said strip.
