Description
Technical field
The present invention relates to planisher technical field of producing, especially a kind of control method of wet jetting piles automatic liquid matching.
Background technique
Wet jetting piles are the technique in planisher entrance side towards working roll injection leveling precision, have a set of sky in planisher outlet side
Gas blowout sweeps system for drying belt steel surface, and the good washing effect of wet jetting piles can be removed effectively and be attached to patch carbon of roll surface etc.
Impurity, reduce load mould the defects of appearance, to prevent thermal expansion of rollers, stabilizing roller shape have positive effect.
The concentration of the used leveling precision of wet jetting piles plays very important effect to the quality of strip, at present factory Nei Duocai
Leveling precision is configured with the mode of conductivity controlled concentration, and conductivity measuring apparatus can generate biggish mistake after long-term use
Difference, and it can not be adjusted, the quality of strip can be seriously affected.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of control of dosing concentration accurately wet jetting piles automatic liquid matching
Method.
To solve above-mentioned technical problem the technical scheme adopted by the invention is that: a kind of controlling party of wet jetting piles automatic liquid matching
Method, comprising the following steps:
Step 1: starting pneumatic operated valve fills the water Agitation Tank；
Step 2: stopping water filling when water level reaches water distribution shutheight；
Step 3: the stoste ratio of corresponding setting concentration value is calculated, according to the setting of metering pump while water filling stops
The runing time of flowmeter calculating metering pump；
Step 4: stoste in original fluid container is transported to Agitation Tank by starting metering pump, according to operation calculated in step 2
Time runs metering pump；
Step 5: the blender for starting Agitation Tank is stirred mixed liquor in Agitation Tank after stoste is injected；
Step 6: stirring is completed to liquid, the wet-leveling liquid prepared is delivered to blending tank and is used to carry out by starting dispenser pump
Subsequent production；
Step 7: being again started up pneumatic operated valve water filling after the wet-leveling liquid in Agitation Tank is delivered to the liquid level of setting and going forward side by side
Row next round works with liquid.
Water distribution liquid level is detected further, being equipped with liquidometer in the step 2 in Agitation Tank.
Further, blender is persistently stirred in Agitation Tank during dispenser pump conveying in the step 6.
Further, mixing time is 3 minutes in the step 6.
Further, being equipped with drain valve between pneumatic operated valve and Agitation Tank.
The beneficial effects of the present invention are: liquid is matched in the automation that leveling precision can be achieved in the present invention, dosing concentration is accurate, does not have
Manual intervention, and can realize by the monitoring to liquid level in Agitation Tank to determine whether carrying out next round matches liquid from matching
The whole-course automation that liquid is used to leveling precision can constantly continue feed flow in temper rolling technology production, to improve production efficiency.
Detailed description of the invention
Fig. 1 is flow diagram of the invention.
Specific embodiment
To facilitate the understanding of the present invention, the present invention is further detailed with reference to the accompanying drawing.
As shown in Figure 1, process of the invention is as follows:
Step 1: starting pneumatic operated valve fills the water Agitation Tank, it is connected between pneumatic operated valve and Agitation Tank by U-shaped pipe,
And drain valve is equipped in U-shaped pipe, the control of pneumatic operated valve opening and closing, the injecting process are carried out in this step using automatic control system
Blender in middle Agitation Tank stops working, and guarantees the accurate of Liquid level, prevents to stir caused liquid fluctuating；
Step 2: stopping water filling when water level reaches water distribution shutheight, liquidometer is equipped in Agitation Tank to water distribution liquid level
It is detected, first water distribution is subsequent to match liquid again, and drain valve is closed during water filling, and drain valve interval is opened after the completion of water filling, passes through row
Water valve exhausts the remaining water in U-shaped pipe, guarantees subsequent with water injection not uncontrolled during liquid；
Step 3: the stoste ratio of corresponding setting concentration value is calculated, according to the setting of metering pump while water filling stops
Flowmeter calculates the runing time of metering pump, fills the water volume with liquid by this when water filling stops calculating the filling of stoste
It measures, then calculates the filling time of metering pump by adding amount；
In this step, it is important that metering pump fill the time calculating, first have to calculate water filling volume, Agitation Tank tank body by
The cylindrical body of top and the cone composition of lower section, when matching liquid for the first time, water filling volume must be by Agitation Tank tank body top and the bottom
Liquid level add up；After obtaining water filling volume, the volume of stoste filling is calculated by this water filling volume with liquid,
V2=V1/(1-n/100)-V1, wherein V1For corresponding water filling volume, n is the concentration ratio of setting；Finally calculate metering pump
Fill time, T=V2/V3* 60, wherein T is that metering pump fills time, V2Volume, V are filled for stoste3For the every of metering pump setting
Minute filling volume.
Step 4: stoste in original fluid container is transported to Agitation Tank by starting metering pump, according to operation calculated in step 2
Time runs metering pump, and when the runing time system that metering pump runs to calculating is just automatically stopped the operation of dispenser pump, completion is former
The filling of liquid；
Step 5: the blender for starting Agitation Tank is stirred mixed liquor in Agitation Tank, by water after stoste is injected
It is stirred until homogeneous and mixes with stoste；
Step 6: stirring 3 minutes complete to liquid, the wet-leveling liquid prepared is delivered to blending tank and is used for by starting dispenser pump
Subsequent production is carried out, blender is persistently stirred in Agitation Tank during dispenser pump conveys；
Step 7: being again started up pneumatic operated valve water filling after the wet-leveling liquid in Agitation Tank is delivered to the liquid level of setting and going forward side by side
Row next round works with liquid.
The present invention applicable all skin pass mill groups with wet jetting piles control system in continuous annealing unit, can effectively improve
The precision of leveling precision concentration realizes that leveling precision matches the automation control of liquid process, the quality of leveling precision, while energy can be greatly improved
Enough reduce the residual quantity of workpiece surface leveling precision.
