Description
Technical field
The invention belongs to the cold rolling emulsified spot processing technology field, be specifically related to the blocking-up method of emulsion edge fluid channeling in a kind of cold rolling mill operation of rolling, be applied to all kinds of cold rolling mill units.
Background technology
In the cold rolling mill operation of rolling, the emulsion that is used for rolling lubrication passes through the band steel of the working roll roll gap channelling of strip edge portion to the milling train outlet, causes emulsion residue, as shown in Figure 1.
Carry out limit portion at the compressed air that adopts big flow near the roll gap place traditionally and purge, the channelling of blocking-up emulsion.As shown in Figure 2.But adopt scheme shown in Figure 2 can bring following technical problem:
1, band steel upper and lower surface purging air-flow disturbs mutually, causes edge fluid channeling thoroughly to solve;
2, the convection effect that brings of the compressed air of local big flow can make the roll local temperature reduce, and hot convexity changes, and is unfavorable for the plate shape control with steel;
3, the compressed air purging of the big flow of strip edge portion can cause the local temperature drop of roll, causes roll barrel unbalanced stress to occur in strip edge portion, shortens the service life of roll;
4, a large amount of compressed-air actuated uses are risen electric power consumption per ton steel rapidly;
5, the compressed air of big flow purges and causes on-site noise serious.
Summary of the invention
The object of the present invention is to provide a kind of blocking-up method of emulsion edge fluid channeling, this blocking-up method can effectively be avoided the channelling problem of the emulsion of super wide injection to outlet side.
To achieve these goals, technical scheme that the present invention adopts is: the blocking-up method of emulsion edge fluid channeling, it is characterized in that: emulsion spray beam place is provided with upper left injection baffle plate, upper right injection baffle plate on the cold rolling mill entrance side, at the following emulsion spray beam place of cold rolling mill entrance side lower-left injection baffle plate, bottom right injection baffle plate is set; According to width of incoming band steel, adjust the width between upper left injection baffle plate and the upper right injection baffle plate, make the jeting area of emulsion of emulsion spray beam wide with incoming band steel and overlap; Adjust the width between lower-left injection baffle plate and the bottom right injection baffle plate, make down the jeting area of emulsion of emulsion spray beam wide with incoming band steel and overlap.
The invention has the beneficial effects as follows: adopt upper right injection baffle plate and upper left injection baffle plate, lower-left injection baffle plate and bottom right injection baffle plate to move, guarantee that injection baffle plate is consistent with opening degree and incoming band steel width between the injection baffle plate; Guarantee not spray emulsion, effectively avoided the channelling problem of the emulsion of super wide injection to outlet side in strip width zone in addition.Adopt the mode that changes emulsion spray beam jeting area to solve the emulsified spot that produces owing to the roll gap channelling.
The present invention changes the thinking that tradition is dealt with problems, the mode that does not adopt compressed air to purge is handled the emulsion that flows to the finished strip surface, not only really avoided compressed air to purge the above-mentioned problems of bringing, and, because the present invention stops emulsion contact finished strip fully, therefore, really promote surface quality of products, reduced rolling oil consumption.
