Abstract
The present invention is a kind of quenching press solenoid valve raising frequency method, when next block of steel plate is tapped, clicks on raising frequency on quenching press interface, then opening degree solenoid valve being quickly opened under lastblock steel plate stable state is finely adjusted.Present invention is mainly applied to roller quenching machine raising frequency speed is slow, raising frequency speed is improved, solves the problems, such as that tapping interval caused by being grown due to water stabilization time is restricted and is wasted with energy consumption, it is quick, effective and easy；The present invention substantially reduces the time of quenching press raising frequency stabilization, while adds steel loading rhythm, creates benefit, adds energy utilization rate, and without any cost.
Description
Technical field
The present invention relates to quenching press technical fields, specifically a kind of quenching press solenoid valve raising frequency method.
Background technology
The steel plate of heat treatment production progressively tends to short, thinning, in the case where production task is very heavy, if not controlling life
Rhythm is produced, it is difficult to the continuous quenching in the case where ensureing plate property；In quenching process, water process is usually opened four pumps and is connected
Continuous to supply water, cistern water reach a certain height, quenching press interface can just receive can up-conversion signal, quenching press could raising frequency,
This process probably needs 8 minutes, can not solve the problems, such as that steel plate gapless enters stove.
The content of the invention
The shortcomings that technical problems to be solved by the invention are, overcome the prior art provides a kind of quenching press solenoid valve liter
Frequency method can solve the technical issues of quenching press solenoid valve opening speed is slow, water stabilization time is long.
Applicant is by the way that the study found that valve is opened one by one during quenching press raising frequency, there are stabilization time, present situation is stablized
Time is more than 100S, and the longer water waste of raising frequency time is more serious；It is of the invention from reduction in order to solve this technical problem
Raising frequency stabilization time starts with, and solenoid valve is made to directly reach setting value.
The present invention solve more than technical problem technical solution be：
A kind of quenching press solenoid valve raising frequency method when next block of steel plate is tapped, clicks on raising frequency on quenching press interface, will
Solenoid valve is quickly opened to the opening degree under lastblock steel plate stable state, then according to setting water and actual amount of water it is big
It is small, solenoid valve opening degree to be finely tuned accordingly, actual amount of water is less than normal, and solenoid valve opening degree is tuned up, and actual amount of water is bigger than normal,
Solenoid valve opening degree is turned down.
The beneficial effects of the invention are as follows：Present invention is mainly applied to roller quenching machine raising frequency speed is slow, raising frequency speed is improved,
Solve the problems, such as that tapping interval caused by being grown due to water stabilization time is restricted to waste with energy consumption, it is quick, effectively and
It is easy；The present invention substantially reduces the time of quenching press raising frequency stabilization, while adds steel loading rhythm, creates benefit, increases
Energy utilization rate, and without any cost.
Specific embodiment
Embodiment 1
The present embodiment is a kind of quenching press solenoid valve raising frequency method, and quenching press is roller quenching machine, electromechanical suitable for quenching
The relation such as table that the magnet valve time is long, water stablizes slow processing, raising frequency time and ton molten steel consumption：
As can be seen from the above table, valve is opened one by one during quenching press raising frequency, and there are stabilization time, present situation stabilization times
More than 100S, and the longer water waste of raising frequency time is more serious.The present embodiment is started with from raising frequency stabilization time is reduced, and makes electricity
Magnet valve directly reaches setting value.Specially：During next piece of steel plate tapping, raising frequency is clicked on quenching press interface, solenoid valve is fast
Speed is opened to the opening degree under lastblock steel plate stable state, then according to the specific feelings between setting water and actual amount of water
Condition, solenoid valve opening degree are finely tuned accordingly, and actual amount of water is less than normal, and solenoid valve opening degree tunes up automatically, and actual amount of water is bigger than normal,
Solenoid valve opening degree is turned down automatically.
After use is implemented in the invention, the quenching press raising frequency time drops to 60-80s by original 120-150s, substantially reduces
The time that quenching press is stablized, while add steel loading rhythm, create benefit, add energy utilization rate, and without it is any into
This, annual 1800000 yuan or so of direct economic benefit.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape
Into technical solution, all fall within the present invention claims protection domain.
