Title: Method for cooling immersion tube
Inventor: ASO TOSHIRO
IPC: C21C7/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To obtain the long service life of a refractory by arranging a cooling space surrounded with a metallic wall in the inner part of an immersion tube, inserting a water-cooling pipe in the cooling space, injecting the cooling water to the metallic wall from fine holes opened on the water cooling pipe and making the negative pressure in the cooling space to forcedly cool the immersion tube with the safe method having no fear of steam explosion. SOLUTION: The water-cooling pipe 5 is inserted in the cooling space 4 of the cooling wall 3 in the immersion tube 1. The cooling water is injected from the fine holes opened on the water-cooling pipe 5 to cool the brick 2 through the cooling wall 3. At this time, the pressure in the cooling space 4 is reduced with a blower 7 to promote the vaporization of the water injected from the water-cooling pipe 5. The cooling capacity is improved by taking into account the cooling with this vaporized heat and also, the storage of liquid drips in the pipe is prevented and the steam explosion can be avoided. In the case of developing the fall-out, etc., of the brick 2 from happening, since the cooling-water pipe succeeds to cool with the circulating water, the breakage of the piping and the vaporization of the water in the piping can be prevented.
