Systems and methods for improving process uniformity in a millisecond anneal system are provided. In some implementations, a process for thermally treating a substrate in a millisecond anneal system can include obtaining data indicative of a temperature profile associated with one or more substrates during processing in a millisecond anneal system. The process can include one or more of (1) changing the pressure inside the processing chamber of the millisecond anneal system; (2) manipulating the irradiation distribution by way of the refracting effect of a water window in the millisecond anneal system; (3) adjusting the angular positioning of the substrate; and/or (4) configuring the shape of the reflectors used in the millisecond anneal system.

An insert for a waterless portable heating device can include multiple containers or shelves arranged in layers for insertion into the device. For example, the insert can have multiple compartments to heat multiple separate ingredients at the same time, e.g., without the ingredients touching each other.

A dual-purpose sintering furnace including a furnace body having a furnace chamber, a first furnace mouth and a second furnace mouth which are communicated with the furnace chamber, a furnace door hinged to the furnace body and configured for closing the first furnace mouth, a blocking member lap jointed inside the furnace chamber and configured for blocking the second furnace mouth, a sample stage, an ejection rod fixedly arranged on a sample placement face of the sample stage, a lifting device configured for driving the sample stage to raise or lower, so that the ejection rod pushes the blocking member until the second furnace mouth is opened, and so that the sample stage enters the furnace chamber through the second furnace mouth. The dual-purpose sintering furnace can complete a large amount of sintering as conventional sintering and also implement rapid sintering.

The Invention relates to an atmospheric-pressure acetylene carburizing furnace, comprises a reaction chamber, an acetylene intake duct, an exhaust gas duct, a control and metering apparatus, an exhaust gas measurement apparatus, and a computer controller. The computer controller calculates a total amount of carbon in the furnace and an enrichment rate of a workpiece, and adjusts an acetylene intake volume according to the calculation result until process requirements are met. The Invention realizes carburizing with acetylene under atmospheric pressure and reduces the usage costs while improving the equipment efficiency.

A pressing arrangement includes a pressure vessel comprising a furnace chamber. The furnace chamber comprises a load compartment arranged within the furnace chamber. The furnace chamber comprises at least one pressure medium guiding passage in fluid communication with the load compartment to form an inner convection loop, wherein pressure medium in the inner convection loop is guided through the load compartment and through the at least one pressure medium guiding passage and back to the load compartment, or vice versa. The pressure vessel comprises at least one adjustable throttle configured to selectively impede or obstruct pressure medium flow in at least a portion of the at least one pressure medium guiding passage, thereby selectively selectively impeding or obstructing a flow of pressure medium in the inner convection loop.
