Abstract

Official abstract text for this publication.

A carrier-type heat-treatment apparatus including a furnace main body that includes heaters and a mesh belt that transports an object to be heat-treated into the furnace main body includes a gas pipe arranged inside the furnace main body, the gas pipe being configured to inject a gas into the furnace main body, in which a low-temperature zone and a high-temperature zone are provided inside the furnace main body with the gas, the low-temperature zone being provided on an entrance side of the furnace main body, the high-temperature zone being provided on an exit side of the furnace main body and having a temperature higher than the low-temperature zone.

First claim

Opening claim text (preview).

1 . A carrier-type heat-treatment apparatus including a furnace main body that includes heaters and a mesh belt that transports an object to be heat-treated into the furnace main body, comprising: a gas pipe arranged inside the furnace main body, the gas pipe being configured to inject a gas into the furnace main body, wherein a low-temperature zone and a high-temperature zone are provided inside the furnace main body with the gas, the low-temperature zone being provided on an entrance side of the furnace main body, the high-temperature zone being provided on an exit side of the furnace main body and having a temperature higher than the low-temperature zone. 2 . The carrier-type heat-treatment apparatus according to claim 1 , wherein the gas pipe is arranged above the mesh belt and in a direction intersecting a direction of motion of the mesh belt, and the gas pipe includes a nozzle arranged on a peripheral wall thereof, the nozzle being configured to inject the gas. 3 . The carrier-type heat-treatment apparatus according to claim 1 , wherein an injection direction of the gas is a direction toward an upper portion of the low-temperature zone rather than a vertically downward direction. 4 . The carrier-type heat-treatment apparatus according to claim 1 , wherein the gas has a temperature equal to or lower than a set temperature of the low-temperature zone. 5 . The carrier-type heat-treatment apparatus according to claim 1 , wherein the gas is an inert gas. 6 . The carrier-type heat-treatment apparatus according to claim 1 , wherein the heaters are aligned in a transportation direction of the object to be heat-treated, and a heat insulator is arranged in a gap that is selected from gaps between the heaters aligned in the transportation direction and that is located in the vicinity of the gas pipe. 7 . The carrier-type heat-treatment apparatus according to claim 1 , further comprising a flow gas introduction mechanism configured to introduce a flow gas from the exit side toward the entrance side of the furnace main body, wherein the flow gas is air.
