Title: Apparatus for casting al alloy and method thereof
Inventor: MORISHITA MAKOTO
IPC: B22D43/00
Filed: 1994-11-01
Abstract: PURPOSE: To simply and efficiently prevent the entrapment of oxide film formed on the surface of molten metal into a cast block by arranging an oxide film staying groove overflowing molten Al alloy accompanied with the oxide film through a weir at the pouring hole side of a water cooling mold and arranging a heating device in the weir. CONSTITUTION: The neighborhood of outer periphery of the oxide film 7 formed on the surface of the molten Al alloy 4 is stayed into the oxide film staying groove 14. Further, the weir 11 is continuously or intermittently heated and thus, the neighborhood of the outer periphery of the molten Al alloy 4 surface is kept to the liquid-phase condition to prevent the entrapment of the oxide film 7. Then, since only the molten Al alloy in the liquid-phase condition at the center part except the neighborhood of the inner wall of the mold can be supplied to the lower part of the mold, the cast block having smooth surface can be produced. Therefore, since the crack on the cast block caused by the entrapment of the oxide film 7 is prevented, the cast block can efficiently be transferred to the following process, and the scrap quantity can be reduced and the productivity is drastically improved.

Abstract: PURPOSE:To quickly raise starting low temperature to steady operation temperature with simple mechanism by supplying heated exhaust gas and air to an air electrode by switching, and installing a blower in series in a pipeline extending from a heated gas exhaust pipe to an exhaust pipe on an air electrode outlet side. CONSTITUTION:For starting a system, heated exhaust gas in a heated gas exhaust pipe 12 is supplied to an air supply pipe 16 by switching a four-way switching valve 18, and supplied to an air electrode 23 of a fuel cell 2 and a cooling passage 24. Since the heated exhaust gas is actively sucked with a blower 9, excessive air is mixed from the suction hole of a burner 3 to form a gas containing a large amount of unreacted oxygen. This gas reacts with hydrogen in a reformed gas supplied to a fuel electrode 22 for power generation. Since temperature of heated exhaust gas is high, a cell 2 whose temperature is low in starting is heated to steady operation temperature.
