摘要： A flow control device for the outlet nozzle for a molten metal handling vessel, such as a ladle, includes a plug that fits in the outlet nozzle to define a gap between the plug and a closure for the nozzle. The plug has a plurality of apertures which are closed by steel plates, or other material, that melts under the influence of the molten metal in the vessel. When molten metal is placed into the vessel and the closure for the outlet is opened, the molten metal flows into the apertures, melting the meltable material in the apertures, and out the outlet. Using a device and method described allows the amount of molten metal in a ladle to be reduced to about 0.5%, and a greater than 99% free opening rate can be provided.

摘要： In an electric arc furnace system for making steel, a method and structure (1) for eliminating teeming hang-ups and ensuring temperature homogeneity in a ladle which teems into an ingot mold by gas purging at all possible steps under both atmospheric and vacuum conditions, and (2) for preventing non-metallic inclusions from appearing in the final product by deflecting the granular material in the teeming ladle well block away from the ingot mold by a heat resistant but combustible deflector just prior to entry of the teeming stream into the ingot mold.

摘要： A pouring system comprises a crucible having an opening formed on a bottom thereof, and a self-sealing member blocking the opening. The self-sealing member is made of material which is the same as the raw material received within the bottom of the crucible. The crucible is supported on an inner distributor supported on a driving rod. The self-sealing member, inner distributor, driving rod are substantially located in a mold heating zone above which a smelting zone is disposed. When the raw material in the crucible is heated in the smelting zone by a first heat source to melt, the driving rod pushes the bottom of the crucible upward into the smelting zone. The self-sealing member is thus molten in the bottom of the crucible, un-blocking the opening to allow the melt to flow therethrough. The melt then flows through an inner distributor and flow pipes into a turnport and reaches a level condition after about 10 seconds. The driving rod is then lowered down to open pouring holes formed on the bottom of the turnport to allow the melt to flow therethrough into molds located directly under the pouring holes.

摘要： A steel ladle drainage method is achieved by using a steel ladle structure. Vacuum interlayers are provided within an upper nozzle, an upper fixed plate, a lower fixed plate and a sliding plate of the steel ladle structure respectively. In the steel ladle drainage method provided by the present invention, a metal drainage agent is used to replace the drainage sand in the prior art, the metal drainage agent is melted by the liquid steel and deposited in the upper nozzle, the sliding plate with the vacuum interlayer and the upper nozzle with the vacuum interlayer have the insulation effect on the melted metal drainage agent. Moreover, through moving the sliding plate, the two pouring holes of the upper and lower fixed plates are connected with each other, the metal drainage agent enters the tundish through the pouring holes and the lower nozzle under the action of gravity.
