Description
Technical field
The present invention relates to the secondary apparatus field of metal-pressed machine, it is specially a kind of for cold-rolling pickling aligning and
The blow device and its application method of straightening section strip steel.
Background technique
Cold-strip steel is in pickling unit aligning and tension leveling segment, because broken unicorn roller, straightener and withdrawal straightening machine can make it at work
Physical form changes and its surface is made to generate the thin iron powder of more oxidation.If not aoxidizing thin iron powder to these to carry out effectively
It collects, partial oxidation iron powder can be brought into withdrawal straightening machine, and rolling by withdrawal straightening machine can make brown iron oxide be pressed into strip, to make band
Steel surface generates impression, and belt steel surface easily forms small rut after overpickling, seriously affects the surface quality of strip.In addition,
The iron powder to descend slowly and lightly will affect the working environment in the region, and pole is unfavorable for the health of operator.
At present in cold-rolling pickling aligning and tension leveling segment, dust pelletizing system is nearly all using above and below the strip of continuous transmission operation
Surface adds the mode of suspended hood, and the dusty gas of sucking is sent to deduster by dedusting air hose, after processing qualified discharge.But
This dedusting method usually has very big drawback:
1) it aoxidizes thin iron powder and is generally all sticked to belt steel surface, common dust hood is difficult to generate enough air draught air-flow generals
It is sucked.
2) to avoid dust hood from colliding with strip, the strip of general dust hood and continuous operation must be maintained a certain distance,
This allows dust hood to be power to the thin iron powder of belt steel surface is adhered to there are no opinion.
So existing common dedusting method aoxidizes the dust removing effects of thin iron powder nearly all very to cold-rolling pickling belt steel surface
It is limited, cause to align in cold-rolling pickling and tension leveling segment, belt steel surface can usually accumulate and largely aoxidize thin iron powder, and with strip
Operation be transmitted to whole region.These thin iron powders all can to the health of strip surface quality and region operator
It has adverse effect on.
Summary of the invention
In order to overcome the drawbacks of the prior art, a kind of easy for installation, the secondary equipment of purging deashing more thoroughly is provided,
The invention discloses a kind of blow devices and its application method for cold-rolling pickling aligning and straightening section strip steel.
The present invention reaches goal of the invention by following technical solution:
A kind of blow device for cold-rolling pickling aligning and straightening section strip steel, including integrated support part, it is characterized in that: also
