Filed: 1995-02-15
Abstract: PURPOSE: To produce a cast ingot having good surface equal to a bottom pouring ingot-making method with little equipping cost and working burden by arranging a cylindrical splash preventing tube in a mold. CONSTITUTION: The splash preventing tube 4 is hung down on the upper surface of the mold 2 set on a molding plate 7 through a holding tool 3. Molten steel 5 is poured into the mold 5 by molten steel pouring flow 1 from the upper part. The splash 6 is cut off with the splash preventing tube 4 and is not spattered in the inner surface of the mold 2. Even in the case of operating with a top pouring ingot-making method, the molten steel surface is quietly ascended as the same condition as the bottom pouring ingot-making method. Therefore, the steel ingot having good surface can be produced. The splash preventing tube 4 is melted in accordance with the ascendent of molten steel surface. The material of the splash preventing tube 4 is selected under consideration of the component variation of the base molten steel 5.  Thus, in the case of selecting the material of the splash preventing tube 4 with a low m.p. refractory, this tube is melted and floated up on the molten metal surface and the effect is not given to the component of the base molten steel 5.

Abstract: PROBLEM TO BE SOLVED: To obtain a process for producing optical elements which prevents the occurrence of the large recessed parts formed on the rear surfaces of glass bottles by adopting a specific method at the time of obtaining glass gob by receiving fused glass flow in a receiving mold. SOLUTION: The glass gob which is the blank for forming the optical elements is obtd. by receiving the fused glass flow flowing out of the outlet of an outflow pipe for the fused glass in the receiving mold consisting of a porous material.

In the initial stage of this stage, the flow rate of the ejecting gas is increased and is then decreased. The gas flow rate at the time of the decrease is set at such a flow rate at which the rear surface of the fused glass does not come into contact with the receiving surface of the receiving mold. The switching of the flow rate is preferably executed continuously.
