Ladle for spheroidizing and manufacturing process thereof

Abstract

The invention belongs to the field of ladles, and relates to a ladle for spheroidizing. The ladle for spheroidizing comprises an upper side wall constructed by refractory bricks, and a spheroidizing chamber moulded by casting castable, wherein the lower part of the upper side wall and the upper part of a side wall of the spheroidizing chamber are connected in a sealing way; and the spheroidizing chamber comprises a dam located on the inner side of the bottom part of the spheroidizing chamber and used for dividing the inner part of the spheroidizing chamber into a cushion pit and a spheroidizing agent placement pit. A manufacturing process of the ladle for spheroidizing provided by the invention comprises the steps of (1) preparing raw materials of the castable of the spheroidizing chamber;(2) starting casting for the spheroidizing chamber; (3) baking and sintering the spheroidizing chamber; (4) manufacturing a packing of the upper side wall; (5) baking; and (6) heating the ladle through high-temperature molten iron for 2 to 3 times. The ladle for spheroidizing and the manufacturing process provided by the invention have the characteristics of long service life of the ladle, low cost, low difficulty in manufacturing, and an excellent ladle spheroidizing effect.

Description

technical field [0001] The invention relates to a molten iron ladle, more specifically, to a molten iron ladle for spheroidizing treatment and a manufacturing process thereof. Background technique [0002] The molten iron ladle is used for the pouring operation in the iron and steel foundry workshop. After accepting the molten iron in front of the furnace, it is transported to the casting mold by driving for pouring. When pouring, the deceleration mechanism installed on the bag body is driven manually or electrically to make the bag body tilt, and the casting mold is poured. The spheroidizing ladle is different from the gray iron ladle. Generally, a dam is set at the bottom of the ladle. During spheroidizing treatment, the spheroidizing agent is placed on the other side of the water outlet, which is also close to the pouring side, so as to avoid the impact of the molten iron on the spheroidizing. Agent hedging, play the effect of delaying the nodularization. However, the m...

AI Technical Summary

Problems solved by technology

Due to the limited strength of the refractory brick dam 2', coupled with the erosion and erosion of molten iron, the refractory brick dam 2' will collapse soon and need to be rebuilt. In the past, the cost and spheroidizing quality will inevitably be affected

[0004] (2) A traditional type of ladle is poured and formed with castables as a whole. Because the castables are expensive, the overall production cost is relatively high, and because the side walls of the ladle are high, the pouring process requires high requirements and is difficult to manufacture. At the same time, it requires Use special equipment to sinter the lining material
