Abstract
The invention relates to a stream inoculant flow control device and a cast iron stream inoculation technology. The stream inoculant flow control device comprises a funnel with a handle; the lower end of the funnel is provided with a quantitative nozzle connected with the lower end of the funnel statically; and the middle of the quantitative nozzle is provided with a through hole for an inoculant to flow out. The cast iron stream inoculation technology comprises the following steps of: statically connecting the handle on one side of the funnel; connecting the quantitative nozzle at the bottom of the funnel, wherein the middle of the quantitative nozzle is provided with the through hole for the inoculant to flow out; filling the inoculant in the funnel, and keeping the quantitative nozzle in an approximately horizontal state by controlling the handle; and keeping the quantitative nozzle in an approximately vertical state that the tail of the quantitative nozzle is downward by rotating the handle, and making the inoculant fall off the funnel and fall into flowing molten iron to be inoculated for stream inoculation. The device is simple in structure, convenient to operate and accurate in quantitation and can be replaced; and by the technology, the product quality is improved, the technology is convenient and practical, and labor time is saved.
Description
Technical field
The present invention relates to the Cast Iron Melting Technique field, specifically, relate to a kind of current-following inoculation agent flux control device, simultaneously, also relate to a kind of cast iron stream inoculation treatment technology.
Background technology
Cast iron is used very extensive as a kind of cast material.In improving the process of cast iron, have epoch making significance on the history of metallurgy that appears at cast iron of inoculated cast iron, inoculation is raising intensity, improves the effectively means of graphite shape and distribution thereof, thereby has obtained widespread usage.
In view of ageing (will fail in the several minutes) of inoculation, it is particularly important that current-following inoculation just seems.And current-following inoculation dosage is very few, and the effect of inoculation is bad; Current-following inoculation dosage is too much, and cast iron can produce segregation, dissolves insufficiently also can cause the cinder hole defective.
Summary of the invention
The objective of the invention is at top described problem, a kind of current-following inoculation agent flux control device is provided, and this flow rate control device is applied in the cast iron stream inoculation processing.
Therefore, another object of the present invention provides a kind of cast iron stream inoculation treatment technology.
In order to realize purpose of the present invention, the technical solution used in the present invention is:
A kind of current-following inoculation agent flux control device comprises the funnel that has handle, and the funnel lower end has the quantitative mouth of static connection with it, and the middle part of described quantitative mouth has and is used for for the effusive through hole of nucleating agent.
Described quantitative mouth and funnel lower end are dismountable static connection.
Described quantitative mouth is connected by the screw thread that is complementary with the funnel lower end, and described quantitative mouth comprises more than three and each quantitative mouth internal diameter difference bottom.
A kind of cast iron stream inoculation treatment technology is characterized in that, may further comprise the steps:
At funnel one side static connection one handle;
Described quantitative mouth and funnel lower end are dismountable static connection.
Described quantitative mouth is connected by the screw thread that is complementary with the funnel lower end, and described quantitative mouth comprises more than three and each quantitative mouth internal diameter difference bottom.
Beneficial effect of the present invention is:
Current-following inoculation agent flux control device of the present invention adopts the method that sets metering jet in funnel bottom, changes different quantitative mouths according to different nucleating agent traffic demands, thereby reaches the purpose of control current-following inoculation dosage.This device has simple in structure, easy to operate and quantitative characteristics such as accurate, and can change different quantitative mouths according to different nucleating agent traffic requirements, and a pipeful of many usefulness have reduced cost.
Adopt the current-following inoculation method of control device of the present invention, realized molten iron when casting by casting personnel controls revolution handle, nucleating agent begins to breed with molten iron stream, casting stops to breed so synchronous current-following inoculation when finishing, assay shows, metallographic structure do not adopt present method in the past better, more stable, improved quality product greatly, and convenient, practical, economize labor time.
Description of drawings
Fig. 1 is the structural representation of current-following inoculation agent flux control device of the present invention.
Fig. 2 analyses and observe enlarged diagram for the funnel and the assembly structure of quantitative mouth.
Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment: referring to Fig. 1, Fig. 2.
A kind of current-following inoculation agent flux control device comprises the funnel 2 that has handle 1, and funnel 2 lower ends have the quantitative mouth 3 of static connection with it, and the middle part of described quantitative mouth has and is used for for the effusive through hole of nucleating agent.
Quantitatively mouth 3 is dismountable static connection with funnel 2 lower ends.
Quantitatively mouth 3 is connected by the screw thread that is complementary with funnel 2 lower ends, and quantitatively mouth 3 comprises more than three and each quantitative mouth internal diameter difference bottom.
The utility model is mainly used in cast iron stream inoculation and handles, and its embodiment is as follows:
Connect quantitative mouth 3 in funnel 2 bottoms, the middle part of described quantitative mouth 3 has and is used for for nucleating agent 4 effusive through holes;
Make quantitative mouth 3 keep terminal downward near vertical state by rotary handle 1, nucleating agent 4 falls from funnel, falls into mobile iron liquid to be bred, and carries out current-following inoculation and handles.
Quantitatively mouth 3 is dismountable static connection with funnel 2 lower ends.
In the present embodiment, quantitatively mouth 3 is connected by the screw thread that is complementary with funnel 2 lower ends.
Quantitatively mouth 3 comprises more than three and each quantitative mouth internal diameter difference bottom, can change different quantitative mouths 3 according to different nucleating agent traffic requirements.Employing is threaded, and perhaps dismountable static connection of other common modes is convenient for changing.
Device of the present invention and technology include but not limited to above-mentioned embodiment, and every structure, principle, working method are identical with the present invention, or the simple substitute of known technology, all drop within protection scope of the present invention.
