Example Embodiment

[0017] In order to solve the above-mentioned drawbacks, the inventor of the present application invented an automatic inoculant monitoring device.

[0018] The following structural drawings illustrate this application in detail.

[0019] The automatic monitoring system for casting and pouring following inoculation includes a system control cabinet 1, a main control unit 2, a display and input unit 3, a data acquisition unit 4, and an execution unit 5. The main control unit can adopt various programming controllers of Siemens and other companies in the prior art. The S7-200 programmable controller (PLC) used in this application. The display and input unit adopts TPC7062KX touch screen, which can input parameters And display data, draw flow curve. The main control unit is installed inside the system control cabinet, the display and input unit is installed on the front panel of the system control cabinet, and the display and input unit is connected to the main control unit through an...

Abstract

The invention relates to a casting pouring metal-stream inoculation automatic monitoring system which comprises a system control cabinet, a master control unit, a display and input unit, a data collection unit and an execution unit. The display and input unit is connected with the master control unit through a signal line. The data collection unit comprises an intelligent instrument and a mass flowmeter which are in line connection. The mass flowmeter is mounted on a conveying pipe of a metal-stream inoculation agent. The master control unit is connected with the mass flowmeter. The executionunit comprises a pouring machine shutdown switch and an alarm. The pouring machine shutdown switch and the alarm are connected with the master control unit. The master control unit is further connected with a pouring machine operation switch on a pouring machine, an infrared molten iron detector and a metal-stream inoculation agent conveying motor encoder. The pouring machine shutdown switch and the pouring machine operation switch are in line connection. In the pouring process, the metal-stream inoculation agent is added timely, continuously and evenly, and therefore it is guaranteed that themetal-stream inoculation effect is stable, the performance of a casting gold phase and materials is stable, and defective products are reduced.

Description

technical field [0001] The invention relates to a casting automatic pouring equipment, in particular to an automatic monitoring system for inoculating dose and speed with flow during automatic pouring. Background technique [0002] As the market has higher and higher requirements on the quality of castings, producing high-quality castings has gradually become a weight problem for manufacturers to solve. Inoculation treatment is a treatment process in which a small amount of certain substance is added to the molten metal before or during the pouring process to affect the nucleation process of the molten metal and thereby change its solidification characteristics. It can promote graphitization, reduce the tendency of white mouth, improve the morphology and distribution of graphite, increase the number of eutectic groups, and refine the matrix structure, which plays a vital role in the quality of castings. For cast iron, the purpose of inoculation is to increase the graphite c...
