Method and Apparatus for Continuous Thermal and Magnetic Annealing

Disclosed is a method and apparatus for performing continuous thermal or magnetic annealing of magnetic materials or parts. It is to be used in conjunction with commercial strand quench/anneal heat treating equipment. It is adaptable to do quenching, thermal annealing, or magnetic annealing.

Fig. 1 illustrates the overall view of the commercial equipment into which these disclosed inserts are fitted. They are inserted into the right side of the cooling section and extend through it to the hydrogen inlet at the center.

Typically, stock enters the heating section from the supply coils on the left and is heated in the presence of an inert gas, such as dry hydrogen. The stock then continues on through a pipe through the cooling section and is wound in large coils on the take-up reel. Continuous stock may be pulled through from the supply end, or in an inclined set-up, parts may be gravity fed into the input with the output end regulating the rate of advancement.

In Fig. 2, Fig. 3, and Fig. 4 the outermost tube (pipe) on the left side is a part of the existing production set-up. Parts within the outer tube and extending to the right of the right end of the outer tube are the subject of this disclosure. Except for the shortened length of the cooling section, the figures are scaled approximately 2X.

Fig. 2 shows the insert installed to perform a quenching operation on continuous stock. The cooling fluid enters the annular space between the two tubes of the insert and travels to the left side of the cooling section, then via cross holes, enters the centr...
