Description

Device for stream inoculation treatment of nodular cast iron in front of intermediate frequency furnace

Technical Field

The utility model belongs to the field of metallurgy, concretely relates to nodular cast iron stream inoculation processing apparatus before intermediate frequency furnace stove.

Background

Stream inoculation is an important process control link in the production process of nodular cast iron castings, the nodulizing quality of nodular cast iron is directly influenced by the stream inoculation effect, whole ladle molten iron is scrapped when the whole ladle is serious, the stream inoculation is generally carried out by manually throwing a shovel and a shovel onto flowing molten iron, or inoculant is separately filled into small bags, one bag is thrown into a molten iron nodulizing ladle, and the inoculation effect is not easy to guarantee.

The contents of the utility model

An object of the utility model is to provide a handling arrangement is bred along with flowing to before intermediate frequency furnace stokehold nodular cast iron to solve the problem of breeding badly along with flowing in the nodulizing process of intermediate frequency furnace stokehold.

In order to solve the above problems, the utility model discloses the technical scheme who takes is:

the utility model provides a nodular cast iron along with flowing breeds processing apparatus in front of intermediate frequency furnace, including fixing at subaerial support base, which comprises a bracket, the hopper, the support comprises stand and crossbeam, the bearing frame is equipped with on the support base, install first bearing on the bearing frame, first bearing is connected with the stand, fixed turning handle on the stand, the top and the crossbeam of stand are fixed, the hopper includes the storage hopper, the discharging pipe, the ration picture peg, rings, the storage hopper hangs in the crossbeam lower part through rings, the storage hopper lower extreme is equipped with the discharging pipe, the ration picture peg inserts between storage hopper and the discharging pipe, ration picture peg lower part is equipped with ejection of compact control picture peg, install support strutting arrangement on the stand, support strutting arrangement is including supporting bearing seat, the second bearing, supporting bearing bolt fixes on the intermediate frequency furnace lateral wall, form triangular supports through.

The utility model has the advantages as follows:

through rotatory twist grip, the stand rotates the storage hopper that drives under the crossbeam, rotates to intermediate frequency furnace taphole top, and during the molten iron tapping, opens ejection of compact control picture peg, and inoculant evenly flows in the molten iron along the discharging pipe, because the design of ration picture peg, can control the velocity of flow, inoculant and molten iron intensive mixing breed the effect ideal, the utility model discloses simple structure, convenient operation can rotate the assigned position after using, does not influence other operations of smelting.
