Problems solved by technology

[0002] In the production process of cast iron, the existing inoculation treatment method generally adopts the method of inoculation by pouring the ladle, that is, the first inoculation treatment is carried out in the ladle and then poured into the pouring furnace. However, the molten iron after the first inoculation Staying in the pouring furnace for a long time will lead to inoculation decline, poor inoculation effect, and easy to bring residue into the pouring furnace. At the same time, in order to deal with the problem of inoculation decline, it is often necessary to use long-acting inoculants and increase the dosage, resulting in production Increased costs

Abstract

The invention discloses an inoculation treatment method for cast iron. The inoculation treatment method comprises the following steps: directly pouring molten iron which is not subjected to inoculation treatment into a pouring furnace; adding a first inoculant into a water outlet groove of the pouring furnace for inoculation treatment for the first time; and adding a second inoculant to the water outlet end of the water outlet groove through a stream inoculation device for inoculation treatment for the second time. By adopting the inoculation treatment method, the inoculation effect of the molten iron is good, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of cast iron preparation, in particular to an inoculation treatment method of cast iron. Background technique [0002] In the production process of cast iron, the existing inoculation treatment method generally adopts the method of inoculation by pouring the ladle, that is, the first inoculation treatment is carried out in the ladle and then poured into the pouring furnace. However, the molten iron after the first inoculation Staying in the pouring furnace for a long time will lead to inoculation decline, poor inoculation effect, and easy to bring residue into the pouring furnace. At the same time, in order to deal with the problem of inoculation decline, it is often necessary to use long-acting inoculants and increase the dosage, resulting in production Increased costs. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems in the prior ...
