A method of annealing a steel sheet in an annealing furnace, including: supporting and conveying a steel sheet with hearth rolls; and supporting and conveying the steel sheet with a full-ceramic hearth roll as a hearth roll located in an area where a furnace temperature is equal to or higher than 950 C., wherein a main constituent of the full-ceramic hearth roll is silicon nitride with use of an AlY-based sintering aid.

A tool for simultaneous local stress relief of each of a multiple of linear friction welds includes a columnar track defined along an axis, the columnar track having a helical slot; and a support structure engaged with the helical slot to translate and rotate a heat treat fixture portion along the axis.

A system for manufacturing a part is provided. The system includes a gantry, a first mobile arm and a second mobile arm, at least one conveyor and at least one sensor. The gantry has a first member and a second member disposed opposite the first member so as to define an opening. The first and the second mobile arms are disposed on the first and the second members, respectively. The at least one conveyor is operative to move the part through the opening so as to position the part within access of the first and the second mobile arms. The at least one sensor is operative to guide the first and the second mobile arms to one or more areas of the part. The first and the second mobile arms are operative to perform a manufacturing process on the part at the one or more areas.

A decompression heat-insulating pipe structure that can exhibit the desired heat-insulating performance and is easy to assemble. In the structure, a space between ends of inner and outer tubes is decompressed. The outer tube includes a first flange, which extends radially inward from an axially one end thereof, and a second flange, which extends radially outward from the axially other end thereof. The inner tube includes a third flange, which extends radially inward from an axially one end thereof and is opposed to the first flange at an axially inward position of the first flange, and a fourth flange, which extends radially outward from the axially other end thereof and being opposed to the second flange at an axially outward position of the second flange. First and second elastic seal members are disposed between the first and third flanges and between the second and fourth flanges, respectively.

The present invention is a processing method for a metal component by using a processing furnace. The method includes the steps of: introducing an activation atmospheric gas into the processing furnace; heating the activation atmospheric gas in the processing furnace to a first temperature; introducing a nitriding atmospheric gas or a nitrocarburizing atmospheric gas into the processing furnace; and heating the nitriding atmospheric gas or the nitrocarburizing atmospheric gas in the processing furnace to a second temperature. The activation atmospheric gas is introduced into the processing furnace through a pipe for introducing the activation atmospheric gas. A liquid organic solvent is introduced intermittently a plurality of times into the pipe for introducing the activation atmospheric gas which is under a state wherein the activation atmosphere gas continues to be introduced.
