发明名称	LANCE PIPE
摘要	PROBLEM TO BE SOLVED: To provide a lance pipe which can suppress gas leak from a portion other than a tip part and which can prevent breakage by enhancing oxidation resistance.SOLUTION: A lance pipe 10 comprises a bottomed-cylindrical gas bubbling part 11 and a cylindrical non-bubbling part 12 formed integrally. Porosity of the gas bubbling part is formed to be higher than porosity of the non-bubbling part at least by 5%. Thereby, ventilation resistance of the gas bubbling part can be made relatively smaller than that of the non-bubbling part. Therefore, when the lance pipe is immersed in molten metal, gas leak from a portion other than the gas bubbling part releasing fine air bubbles in molten metal can be suppressed. Also, intensity and oxidation resistance can be enhanced by lowering porosity of the no-bubbling part, so that breakage of the lance pipe can be prevented.SELECTED DRAWING: Figure 1
