Background technology
Requirement with market to casting quality is higher and higher, and the casting for producing high-quality is increasingly becoming producer and is solved
Weight issue.Inoculation is exactly that certain a small amount of substance is added before cast or in casting process into molten metal, with shadow
It rings molten metal and gives birth to nuclear process, to change the treatment process of its coagulating property.It can promote graphitization, reduce chilling tendency, improve
Graphite form and distribution situation increase eutectic cell quantity, refine matrix, vital work is played to the quality of casting
With.For cast iron, the purpose bred is the graphite nuclei increased in iron liquid, so that the analysis of eutectic freezing, especially graphite
Going out can proceed by under smaller degree of supercooling, and current-following inoculation processing procedure refers to being added in casting process with iron liquid centainly
The inovulant of ratio, as a result, the tendency of Graphite Precipitation is improved, and the tiny graphite being evenly distributed, to make cast iron
With good mechanical property and processing performance.Current-following inoculation processing is the key property during castings production.Inovulant is certainly
Body quality, filling time, adding amount and the uniformity of adding amount can all influence the quality of casting in the unit interval, wherein filling
Amount and the filling technical barrier that uniformity is particularly important and manufacturer faces.
Traditional casting machine itself transmits automatic addition equipped with " random inoculant added automatically system " by worm screw, has
Certain limitation.
1, the number of random inoculant discharge cannot real-time continuous, quantitative measurment, monitoring.

Machine run switch, infrared molten iron detector are connected with random inoculant feeder motor encoder, the casting machine in system control cabinet
Halt switch passes through connection with the casting machine run switch on casting machine.
The beneficial effects of the invention are as follows：
1, in casting process, the addition of random inoculant in time, continuously, uniformly to ensure current-following inoculation effect stability, is cast
Part metallographic and material property are stablized, and the generation of defective products is reduced.
2, random inoculant additive amount can realize continuous, quantitative measurment, monitoring in casting process.Ensure random inoculant
Addition is uniform, continuous.
3, automatic alarm, autostop can be realized when random inoculant addition occurs abnormal in casting process, it is ensured that with
Stream breeds abnormal production process and is automatically stopped, and avoids producing the defective product of performance.
4, main control unit uses S7-200 programmable controllers（PLC）Dependable performance, programming are convenient.
5, display and input unit use TPC7062KX touch screens, data input convenient, intuitive.
6, data acquisition unit uses Germany MEYLESDT11 type microwave solids mass flowmenters, superior performance, precision high.
Using solid mass flow meter as the detection sensor of stream inoculant flow, it is ensured that promptness, the accuracy of data acquisition.
