Abstract
In the heat treating method and the heat treatment apparatus of the object, the object is heat treated while it is being floated by gas expelled toward the object from a position below the object in the heating chamber.
Claims54
A method of heat treating an object, comprising:
- floating the object in a heating chamber by expelling gas towards the object from below the object;
- and
- heat treating the object by directing heat from a separate heat source towards the object by said expelling gas.
A method of heat treating an object, comprising:
- floating the object in a heating chamber by expelling gas towards the object from below the object;
- heat treating the object during said floating;
- and
- horizontally moving the object in a movement direction during said heat treating and said floating, wherein the object includes a rear portion and a front portion with respect to said movement direction and said horizontally moving the object includes blowing gas towards said rear portion of the object so that said rear portion shifts up relative to said front portion such that the object is inclined.

A method of heat treating an object, comprising:
- floating the object in a heating chamber by expelling gas towards the object from below the object;
- heat treating the object during said floating;
- and
- horizontally moving the object in a movement direction during said heat treating and said floating, wherein said horizontally moving includes contacting directly adjacent carrying members each of which is adapted to support the object, supporting the object with one of said adjacent carrying members, and pushing a last carrying member of said adjacent carrying members so that all of said carrying members move.
1 more element
A method of heat treating an object, comprising:
- floating the object in a heating chamber by expelling gas towards the object from below the object;
- heat treating the object during said floating;
- horizontally moving the object in a movement direction during said heat treating and said floating;
- and
- stopping the object, wherein the object includes a rear portion and a front portion with respect to said movement direction and said stopping includes blowing gas towards said front portion of the object so that said front portion shifts up relative to said rear portion such that the object is inclined.
2 more elements
A heat treatment apparatus for heat treating an object, comprising:
- a heating chamber;
- an object moving device provided in said chamber to move the object horizontally in a movement direction;
- and
- a floating member provided in said heating chamber, said floating member including a burning opening provided in said floating member to supply heat to the object, a first blowing opening and a second blowing opening, said first and second blowing openings being provided on opposite sides of said burning opening for expelling gas to float the object and to direct heat from said burning opening towards the object.
1 more element
A heat treatment apparatus for heat treating an object, comprising:
- a heating chamber;
- a floating member provided in said heating chamber to expel gas towards the object;
- a heater provided in said chamber;
- and
- an object moving device provided in said chamber to move the object horizontally in a movement direction, wherein the object includes a rear portion and a front portion with respect to said movement direction, said object moving device includes a moving device blowing opening, and said moving device blowing opening is provided upstream from said first and second blowing openings to expel high pressure gas towards said rear portion of the object so that said rear portion shifts up relative to said front portion such that the object is inclined.
2 more elements
A heat treatment apparatus for heat treating an object, comprising:
- a heating chamber;
- a floating member provided in said heating chamber to expel gas towards the object;
- a heater provided in said chamber;
- and
- a stopper provided in said heating chamber provided in said heating chamber to stop the object, wherein the object includes a rear portion and a front portion with respect to said movement direction, said stopper includes a stopper blowing opening provided in said stopper, and said stopper blowing opening is provided downstream from said first and second blowing openings for expelling high pressure gas towards said front portion of the object so that said front portion of the object shifts up relative to said rear portion such that the object is inclined.
2 more elements
