High temperature protection steam channel is equipped with, high temperature protection steam is filled with into annealing furnace 201, prevents wire body 1 from aoxidizing, the high temperature protection steams
Vapour is then the secondary utilization that used heat is produced to baking mechanism.
Production practices prove that wire body 1 is not contacted even in end of incoming cables/leading-out terminal with the tube wall of annealing pipe 202, but is still suffered from
The problem of galled spots is scratched, it is puzzling, through multi-party verification, when technical staff has found that wire body 1 is advanced in annealing pipe 202,
When especially gait of march is very fast, due to the limitation of the length of annealing pipe 202, wire body 1 itself easily occurs naturally drooping phenomenon, causes
The sagging position of wire body 1 is easily in contact with the bottom tube wall of annealing pipe 202, and wire body 1 can be caused along with the continuous traveling of wire body 1
Sustained damage.In the present embodiment the inwall 205 of the bottom of annealing pipe 202 be to lower recess arc inner wall (annealing pipe 202
Exterior design can be for straight trip pipe or curved pipe design, and the inwall 205 that need to only make the bottom of annealing pipe 202 is the arc to lower recess
Inwall), the arc-shaped recess of inwall 205 is corresponding with the hang of wire body 1 so that wire body 1 when there is hang,
Its hanging portion still keeps vacant state, will not be in contact with the inwall 205 of annealing pipe 202, effectively prevent wire body 1 in annealing
The frictionally damage that the inside of pipe 202 is produced, helps to ensure the final mass of follow-up enamel-covered wire.
The end of incoming cables side of annealing pipe 202 is provided with preceding guard plate 203, and leading-out terminal side is provided with rear guard plate 204, preceding
Ceramic ring is provided with guard plate 203 and rear guard plate 204, the upper and lower ends of preceding guard plate 203 are arranged with side shield in parallel,
The side shield extends to the direction close to annealing pipe 202, and the framework surrounded by side shield and preceding guard plate 203 is just to annealing pipe
202 end of incoming cables, the structure of rear guard plate 204 is corresponding with preceding guard plate 203.The rear of annealing pipe 202 is provided with to be entered to wire body 1
The cooling body of row cooling, including cooling water tank 301, scrape water sponge and air dryer 302, wherein cooling water tank 301 is recirculated water
Liquid-level floater valve is provided with case, and cooling water tank 301.The setting of guard plate 204 and preceding guard plate 203 is avoided that annealing furnace afterwards
