Abstract

The invention provides a molten steel feeding system used for preparing amorphous strips. The molten steel feeding system comprises a resistance heating tundish and an induction heating nozzle bag, wherein the resistance heating tundish is used for receiving molten steel and purifying the molten steel; the induction heating nozzle bag is arranged below the resistance heating tundish, used for receiving the molten steel injected by the resistance heating tundish and used for conducting temperature regulating on the molten steel; and a nozzle is arranged below the induction heating nozzle bag and used for pouring of the molten steel. By means of the molten steel feeding system used for preparing the amorphous strips, inclusions in the molten steel can float up so as to achieve the aim of purifying the molten steel; and meanwhile, the temperature of the molten steel can be rapidly adjusted, and the temperature needed for preparing the amorphous strips is achieved.

Description

technical field

[0001] The invention belongs to the technical field of manufacturing amorphous strips, in particular, the invention relates to a molten steel supply system for preparing amorphous strips. Background technique

[0002] At this stage, the preparation of amorphous alloy strips mostly adopts the method of single-roll rapid quenching. The system of single roll quick quenching method is mainly composed of the following parts: smelting furnace, tundish, stopper rod, nozzle package, cooling roll, thickness measuring device and grabbing device. After the master alloy is smelted in the smelting furnace, a molten alloy is formed. The molten alloy is poured into the tundish through the smelting furnace. After the process of slag removal and temperature adjustment in the tundish, it is injected into the nozzle package through the steel pouring port under the tundish, and poured into the cooling roller through the nozzle below the nozzle package. superior. After the mol...
