Stream inoculation assembly used on casting ladle and inoculation method thereof

Abstract

The invention relates to the technical field of casting smelting production, and discloses a stream inoculation assembly used on a casting ladle. The stream inoculation assembly comprises the castingladle, an inoculation hopper, a material blocking ball and a support rotating shaft; one side of the top of the casting ladle is fixedly connected with a fixed base, and one side of the top of the fixed base is fixedly connected with a support fixed shaft. According to the stream inoculation assembly used on the casting ladle and the inoculation method thereof, through the arrangement that the fixed base is fixed to the side rear portion of a ladle nozzle of the casting ladle, the situation that an inoculant is not flushed by molten iron and cannot achieve the purpose of uniform inoculation can be effectively avoided, the fixed base is fixed to the side rear portion of the ladle nozzle of the casting ladle, an inoculation support does not need to be manually held, the inoculation support can rotate, and the inoculant can be added conveniently; and the assembly is simple in structure, stream inoculation is carried out while a stokehole inoculation measure is transferred to the process that molten iron is poured into a receiving ladle from the casting ladle, the time spent during the process from inoculant adding to casting is greatly shortened, and the casting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of casting and smelting production, in particular to a flow inoculation component used on a ladle and an inoculation method thereof. Background technique [0002] Only when there are graphite cores in molten iron can graphite grow by attaching to the cores. Inoculation technology provides graphite with heterogeneous nucleation. If the number of cores is large, the number of graphites is large, and the graphite is small, which can play a role in refining grains. The gold of castings The phase and material are good. After the inoculant is added to the molten iron, the molten iron has a decay property. After a certain period of time, the longer the time, the fewer graphite cores, which requires the shorter the time from the completion of inoculation to plugging and pouring. [0003] In actual production, due to the limitation of the workshop site, the temperature of molten iron, and the safety of personnel oper...

Problems solved by technology

[0004] Aiming at the deficiencies of the current inoculation component used on the ladle and its inoculation method, the present invention provides a current inoculation component used on the ladle and its inoculation method, which has the ability to transfer the inoculation measures in front of the furnace to When the ladle is pouring the molten iron into the seat ladle, the inoculation with the flow is carried out at the same time, which greatly reduces the time spent from adding the inoculant to pouring, and the inoculant enters the molten iron through the flow, and the molten iron is fully and evenly inoculated, and the inoculation effect is better. Well, the advantage of a more uniform organization solves the problems raised in the above-mentioned background technology
