Title: Production of good quality steel material by continuous casting
Inventor: KITAYAMA MINORU
IPC: B22D11/128
Filed: 1979-07-23
Abstract: PURPOSE: To obtain a steel material of good quality free from any surface defects by suppressing surface oxidation so as not to allow gas bubbles to oxide at the time of heating the ingot in which the air bubble positions made by casting the molten steel of the specifically controlled free oxygen concentration are specific prior to rolling.  
     CONSTITUTION: The free oxygen concentration of molten steel piror to continuous casting is controlled within a range of 50W150ppm. The positions where the gas bubbles of the ingot obtained by casting this molten metal form go from the positions of 0.3W0.5mm below the surface of the ingot toward the inner side and there are no exposed gas bubbles. However, a solid skin thickness is extremely thin and if the ingot is heated in ordinary hot rolling process, surface defects are produced. Thereupon, the ingot oxidation during this heating, that is, the formation of primary scale, is suppressed by evacuating the atmosphere in the heating furnace or admitting Ar or He therein or coating an antioxidant on the ingot surface.

Then, a resist film 12 is exposed and developed on a carbon film 11, thereby forming a resist film 12' of the prescribed pattern. With the film 12' as a mask the film 11 is reactively ion etched with O2 gas. Then, a resist removing solution such as that in which benzene sulfonic acid is mainly contained, and the resist film is removed. At this time, the film 11' remains. With the film 11' as a mask the film 3 is reactively ion etched with CCl4 and Cl2 gas, thereby forming an patterned Al.Si film 3''. Since the carbon film of this mask is sufficiently thin, side wall accumulation is not produced. Then, the carbon film is ashed with O2 plasma and removed. In this case, the Al.Si film and the SiO2 as the base of the Al.Si film are not entirely etched at all.
