Abstract
According to the present disclosure, a heat treatment apparatus includes a heating treatment unit that heat-treats a strip-shaped sheet while transferring the strip-shaped sheet, and a cooling unit that cools the strip-shaped sheet having been heat-treated in the heating treatment unit while transferring the strip-shaped sheet. The cooling unit includes a cooling roller that allows a refrigerant to flow through the inside thereof, and an outer wall that surrounds the space in which the cooling roller is disposed. The heat treatment apparatus may further include a take-up unit in which the strip-shaped sheet having been cooled in the cooling unit is wound.
Claims9
A heat treatment apparatus comprising:
- a heat treating unit configured to heat-treat a strip-shaped sheet while transferring the strip-shaped sheet;
- and
- a cooling unit configured to cool the strip-shaped sheet having been heat-treated in the heat treating unit, while transferring the strip-shaped sheet,
- wherein the cooling unit comprises
- a cooling roller allowing a refrigerant to flow through an inside thereof,
- wherein the cooling unit comprises an outer wall surrounding a space in which the cooling roller is disposed,
- wherein the heat treating unit includes an outer wall surrounding a space in which the strip-shaped sheet is heat-treated,
- wherein the heat treating unit includes a door disposed at an inlet thereof and configured to switch an atmosphere in the heat treating unit and an atmosphere in a space upstream of the heat treating unit from one to the other, and
- wherein the cooling unit includes a door disposed at an outlet thereof and configured to switch an atmosphere in the cooling unit and an atmosphere in a space downstream of the cooling unit from one to the other.
A heat treatment apparatus comprising:
- a heat treating unit configured to heat-treat a strip-shaped sheet while transferring the strip-shaped sheet;
- and
- a cooling unit configured to cool the strip-shaped sheet having been heat-treated in the heat treating unit, while transferring the strip-shaped sheet,
- wherein the cooling unit comprises a cooling roller allowing a refrigerant to flow through an inside thereof,
- wherein the cooling unit comprises an outer wall surrounding a space in which the cooling roller is disposed,
- wherein the cooling unit includes a plurality of the cooling rollers,
- wherein the plurality of the cooling rollers includes at least one first cooling roller around which the strip-shaped sheet is wrapped so as to be in contact with a first surface of the strip-shaped sheet,
- wherein the plurality of the cooling rollers includes at least one second cooling roller around which the strip-shaped sheet is wrapped so as to be in contact with a second surface of the strip-shaped sheet,
- wherein each of the at least one first cooling roller and the at least one second cooling roller includes a plurality of cooling rollers,
- wherein the strip-shaped sheet is wrapped onto the at least one first cooling roller and the at least one second cooling roller alternately, and
- wherein each of an interval between adjacent ones of the first cooling rollers and an interval between adjacent ones of the second cooling rollers is less than an outer diameter of the cooling rollers.
