Manufacturing method of amorphous ribbon

Abstract

The invention relates to a manufacturing method of an amorphous ribbon. The manufacturing method comprises the following steps of: melting steel into molten steel through a melting furnace; flowing the molten steel in the melting furnace into a spray bag through a passage; flowing the molten steel to a cooling roll from the lower part of the spray bag under the action of gravity; preparing the molten steel into the amorphous ribbon; and after adding all the molten steel in the melting furnace into the spray bag, sealing the spray bag and introducing gas into the spray bag to supercharge to flow all the molten steel in the spray bag to the cooling roll from the lower part of the spray bag and preparing the molten steel into the amorphous ribbon. The manufacturing method is suitable for manufacturing the amorphous ribbon, equipment required by the manufacturing method and a pressure ribbon manufacturing method are relatively simple, the cost is low, the yield of the manufacturing method can reach 100 percent and is far higher than that of a gravity ribbon manufacturing method, and the amorphous ribbon manufactured by the manufacturing method has high quality.

Description

technical field [0001] The invention relates to a manufacturing method of an amorphous ribbon. Background technique [0002] At present, there are two methods for producing amorphous tape: pressure tape method and gravity tape method. The pressure strip method is to melt steel into molten steel through a melting furnace, then add molten steel into a container, seal the upper part of the container and pressurize the inside of the container with gas, so that the molten steel flows out from the outlet of the lower part of the container to the cooling roll, The molten steel is made into an amorphous strip; the preparation method is controlled by pressure throughout the preparation process, and the finished product rate can reach 100%, but the equipment is complicated, the cost of strip making is high, and the production efficiency is low. The gravity belt making method is to melt steel into molten steel through a melting furnace, and the molten steel enters the spray ladle thro...

The pressure strip method is to melt steel into molten steel through a melting furnace, then add molten steel into a container, seal the upper part of the container and pressurize the inside of the container with gas, so that the molten steel flows out from the outlet of the lower part of the container to the cooling roll, The molten steel is made into an amorphous strip; the preparation method is controlled by pressure throughout the preparation process, and the yield can reach 100%, but the equipment is complicated, the cost of strip making is high, and the production efficiency is low

The gravity belt making method is to melt steel into molten steel through a melting furnace, and the molten steel enters the spray ladle through the flow channel, and then under the action of gravity, the molten steel flows out from the lower part of the spray ladle to the cooling roller, and the molten steel is made into an amorphous belt; the preparation The preparation equipment required by the method is relatively simple, but when there is less molten steel left in the spray ladle, this part of molten steel will not flow out again, so the yield is low, and the quality of the obtained amorphous strip is also poor
