Abstract

The present invention relates to field of metallurgy continuous cast mold soft water automatic regulating system。Continuous cast mold soft water automatic regulating system, including the electromagnetic flowmeter being arranged on hose, it is 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, the adjustment upper limit is set and regulates lower limit and Electromagnetic Control valve opening time, then Siemens S7 300 controls the flow of electromagnetic flowmeter between the adjustment upper limit and adjustment lower limit, control the opening time of solenoid electric valve equal to Electromagnetic Control valve opening time simultaneously；Wherein regulate the upper limit=1.02 × target flow size adjustment lower limit=0.98 × target flow size

Description

Continuous cast mold soft water automatic regulating system
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 current continuous cast mold soft water also uses Hand-operated butterfly valve to carry out hand switch soft water, and the quality of iron and steel is impacted by the flow manually controlled very inaccuracy。
Summary of the invention
The technical problem to be solved is: how to solve the coarse problem of continuous cast mold soft water flux。
The technical solution adopted in the present invention is: continuous cast mold soft water automatic regulating system, including the electromagnetic flowmeter being arranged on hose, it is arranged on the solenoid electric valve on hose, Siemens S7300, electromagnetic flowmeter, Electromagnetic Control valve signal connects Siemens S7300, Siemens S7300 is first according to target flow demand, target flow size, the adjustment upper limit is set and regulates lower limit and Electromagnetic Control valve opening time, then Siemens S7300 controls the flow of electromagnetic flowmeter between the adjustment upper limit and adjustment lower limit, control the opening time of solenoid electric valve equal to Electromagnetic Control valve opening time simultaneously；Wherein
Regulate the upper limit=1.02 × target flow size, regulate lower limit=0.98 × target flow size,
。
The invention has the beneficial effects as follows: the present invention improves the accuracy of continuous cast mold soft water flux, reduce the labor intensity of operative employee, record relevant historical data, make discharge have trackability, improve the reliability of steel quality。
Detailed description of the invention
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 S7300, Siemens S7300 is first according to target flow demand, target flow size, the adjustment upper limit is set and regulates lower limit and Electromagnetic Control valve opening time, then Siemens S7300 controls the flow of electromagnetic flowmeter between the adjustment upper limit and adjustment lower limit, controls the opening time of solenoid electric valve equal to Electromagnetic Control valve opening time simultaneously；Wherein
Regulate the upper limit=1.02 × target flow size, regulate lower limit=0.98 × target flow size,
。
In one subtask, target flow requirement is 60 cubic metres, target flow is sized to 2.5 cubic metres per minute, it is 2.55 cubic metres per minute that Siemens S7300 calculates the adjustment upper limit, regulating lower limit is 2.45 cubic metres per minute, and Siemens S7300 reads soft water flux by electromagnetic flowmeter, controls the aperture of solenoid electric valve, making soft water flux per minute between 2.45 cubic metres to 2.55 cubic metres, the time is 24 minutes。
