Embodiment Construction

[0007] 1) Adding method of inoculant by pouring into the bag

[0008] The traditional ladle flushing method is to place the inoculant on the bottom of the molten iron ladle before tapping, and then tap the iron. After the tapping is completed, the slag is removed. In the bag flushing method, first put the inoculant to be added into the bag for later use. When the molten iron reaches about 1 / 3, put the inoculant together with the packaging bag into the molten iron ladle without interrupting the iron tapping, so that the inoculant reacts with the molten iron immediately to produce an inoculant effect, which avoids the inoculation of the inoculant in the hot ladle Oxidation and burning loss, and avoiding the loss that may be caused by the hot air flow when the bulk inoculant is put into the ladle.

[0009] 2) After the molten iron is discharged, use a slag scraper to stir and break the ash formed by the inoculant and scum, and repeatedly press it into the molten iron until aggl...

Abstract

An improved ladle addition technology includes such steps as tapping about 1 / 3 of the molten iron, continuous tapping while adding the modifying agent, breaking the 'ash blocks' formed by modifying agent and float slag, pressing the broken ash blocks in molten iron repeatedly, and skimming.

Description

technical field [0001] The invention relates to an inoculation method for inoculation treatment of molten iron. Background technique [0002] Inoculation treatment of molten iron is an important means to improve the performance of cast iron in modern foundry production. As an important method of inoculation, the traditional bag flushing method is the most widely used and simplest method. The authoritative conclusion is that: the traditional method of pouring into the bag is the simplest, but the inoculant is easy to oxidize and has a large burning loss; long, with the worst recession. [0003] The breeding method has a direct impact on the breeding effect. In order to overcome the deficiencies in the background technology, especially in order to solve how to use the simplest method of flushing into the ladle to inoculate the molten iron for a long time, the inventors have long-term The entry method has been carefully analyzed and tested, and on the basis of the tradition...
