Nodularizing ladle cover

Abstract

The invention provides a nodularizing ladle cover covering a nodularizing ladle. A cover body is provided with a sprue gate; the surface of each of the cover body and the sprue gate is provided with a layer of refractory material used to avoid direct contact between high-temperature molten iron and the material of the cover body and that of the sprue gate. The cover body is further provided with a guide channel used to link the inner wall of the sprue gate and that of the nodularizing ladle; the guide channel is used for guiding the high-temperature molten iron. The nodularizing ladle cover has the advantages that the cover body and the sprue gate are higher in high temperature resistance, spattering of the molten iron during pouring is prevented, service lives of the cover body and the sprue gate are prolonged, and operational safety is guaranteed.

Description

technical field [0001] The invention relates to a spheroidized bag, in particular to a spheroidized bag cover. Background technique [0002] The spheroidizing ladle is a container for the spheroidizing reaction of molten iron. The spheroidizing ladle is usually in the shape of a barrel, and a dam is provided at the bottom of the barrel to separate a space for placing the nodulizing agent. There is also a cover on the top of the barrel, which is called the spheroidizing cover. There is a pouring port on the spheroidizing cover. The molten iron enters through the pouring port on the spheroidizing cover. The agent produces a spheroidizing reaction. The spheroidization cover can block the splashing liquid during the reaction and protect the safety of the operator until the spheroidization reaction is over. [0003] The existing spheroidizing ladle cover and its sprue are all made of steel plates, which have poor high temperature resistance. When high-temperature molten iron en...

AI Technical Summary

Problems solved by technology

[0003] The existing spheroidizing ladle cover and its sprue are all made of steel plates, which have poor high temperature resistance. When high-temperature molten iron enters the spheroidizing ladle through the sprue, the sprue will be damaged, and there is no diversion structure at the sprue. When the molten iron enters the spheroidizing ladle, the height difference is too large, causing the molten iron to splash and adhere to the steel plate

In addition, the molten iron is very intense during the spheroidization reaction, resulting in extremely high temperatures. After a period of time, the steel plate is easily adhered by the splashed liquid, which is difficult to remove, and it will deform and affect the sealing performance. During the chemical reaction, the splashed liquid will splash out through the gap of the deformed steel plate, causing safety hazards to the operators
