Abstract
The invention relates to an automatic adjusting system for continuous crystallizer soft water in the field of metallurgy. The automatic adjusting system for the continuous crystallizer soft water comprises an electromagnetic flowmeter installed on a soft water pipe, an electromagnetic control valve installed on the soft water pipe and a Siemens S7300, the electromagnetic flowmeter and the electromagnetic valve are in signal connection with the siemens S7300, and the siemens S7300 sets the upper adjusting limitation, the lower adjusting limitation and the opening time of the electromagnetic control valve according to the target flow demand quantity and the target flow, and the siemens S7300 controls the flow of the electromagnetic flowmeter to be between the upper adjusting limitation and the lower adjusting limitation and controls the opening time of the electromagnetic valve to be equal to the opening time of the electromagnetic control valve, wherein the upper adjusting limitation is equal to 1.02*the target flow, the lower adjusting limitation is equal to 0.98*the target flow, and the opening time of the electromagnetic valve is obtained by dividing the target flow demand quantity by the target flow.
Description
Technical field
The present invention relates to field of metallurgy continuous cast mold soft water automatic regulating system.
Background technology
Field of metallurgy continuous cast mold soft water is extremely important to metallurgy, and at present continuous cast mold soft water also carries out hand switch soft water with Hand-operated butterfly valve, and the flow by manual control is inaccuracy very, and the quality of iron and steel is impacted.
Summary of the invention
Technical problem to be solved by this invention is: how to solve the coarse problem of continuous cast mold soft water flow.
The technical solution adopted in the present invention is: continuous cast mold soft water automatic regulating system, comprise the electromagnetic flowmeter being arranged on hose, be arranged on the solenoid electric valve on hose, Siemens S7 300, electromagnetic flowmeter, Electromagnetic Control valve signal connects Siemens S7 300, Siemens S7 300 is first according to target flow demand, target flow size, arrange to regulate and reach the standard grade and adjusting is rolled off the production line and Electromagnetic Control valve opening time, then the flow that Siemens S7 300 controls electromagnetic flowmeters is reached the standard grade and between adjusting rolls off the production line in adjusting, the opening time of simultaneously controlling solenoid electric valve equals Electromagnetic Control valve opening time, wherein
,
,
.
The invention has the beneficial effects as follows: the present invention has improved the accuracy of continuous cast mold soft water flow, reduce operative employee's labour intensity, record relevant historical data, make discharge there is trackability, improved the reliability of steel quality.
The specific embodiment
The present invention installs electromagnetic flowmeter and solenoid electric valve in the hose exit of continuous cast mold, electromagnetic flowmeter, Electromagnetic Control valve signal connect Siemens S7 300, Siemens S7 300 is first according to target flow demand, target flow size, arrange to regulate and reach the standard grade and adjusting is rolled off the production line and Electromagnetic Control valve opening time, then the flow that Siemens S7 300 controls electromagnetic flowmeters is reached the standard grade and between adjusting rolls off the production line, the opening time of simultaneously controlling solenoid electric valve equals Electromagnetic Control valve opening time in adjusting; Wherein
,
,
.
In one subtask, target flow requirement is 60 cubic metres, target flow size is 2.5 cubic metres per minute, Siemens S7 300 calculates to regulate and reaches the standard grade as 2.55 cubic metres per minute, adjusting is rolled off the production line as 2.45 cubic metres per minute, and Siemens S7 300 reads soft water flow by electromagnetic flowmeter, controls the aperture of solenoid electric valve, make soft water flow per minute between 2.45 cubic metres to 2.55 cubic metres, the time is 24 minutes.
