Patent ID: 8298475

Claim:
A furnace system comprising: a conveyer device for supporting and transporting a work piece, a furnace facility disposed on said conveyer device and including a pre-heating zone, a high temperature heating zone, a first cooling zone, and a second cooling zone, and said conveyer device being provided for transporting and moving the work piece from said pre-heating zone through said high temperature heating zone and said first and said second cooling zones, a first heating member disposed in said pre-heating zone for pre-heating the work piece, a second heating member disposed in said high temperature heating zone for further heating the work piece, a first piping coupled between said first cooling zone and said pre-heating zone, a second piping coupled between said second cooling zone and said high temperature heating zone, a first blowing device disposed in said first cooling zone for drawing a waste gas from said first cooling zone to said pre-heating zone, a second blowing device disposed in said second cooling zone for drawing a waste gas from said second cooling zone to said high temperature heating zone, an oxygen density controller attached to said high temperature heating zone and including a probe engaged into said high temperature heating zone for detecting a density of an oxygen contained within said high temperature heating zone, and said furnace facility including a temperature control member and a timer attached to each of said pre-heating zone and said high temperature heating zone and said first and said second cooling zones respectively for monitoring a temperature of the work piece, and for controlling a time interval of the work piece within said pre-heating zone and said high temperature heating zone and said first and said second zones respectively.
