Description
Technical field
The utility model relates to a kind of 2 ribbon steel finishing mill dephosphorization systems, belongs to metallurgy industry ribbon steel production equipment technical field.
Background technology
In metallurgy industry ribbon steel is produced, the dephosphorization mode of band steel is generally divided into two kinds: one to be some dephosphorization.Before dephosphorization point is located at roughing mill, this is more conventional at older output strip line; Two is 2 dephosphorization.Before dephosphorization point is located at roughing mill respectively and before finishing mill, the ribbon steel production line built in recent years mostly adopts this dephosphorization mode.
The object of roughing dephosphorization removes the thick and raw iron scale of hard stove, if remove the rolling that only can not affect rough rolling step, also can produce harmful effect to the quality of band steel, before straight carbon steel rolling mill practice requirement roughing mill, dephosphorization pressure is 16MPa simultaneously.The object of finish rolling dephosphorization removes the secondary iron scale produced in rolled piece rough rolling step and output procedure, the secondary iron scale comparatively raw iron scale of stove is easily removed, finish rolling dephosphorization pressure is much lower compared with roughing dephosphorization, and the capacity of equipment of finish rolling dephosphorization system is had " having more than needed ".
Above-mentioned two kinds of main Problems existing of ribbon steel dephosphorization mode: one is that phosphor-removing effect is bad, the secondary iron scale on rolled piece surface, except unclean, affects the quality of final products; Two is wastes of the capacity of equipment of finish rolling dephosphorization system.
Utility model content
The utility model object is to provide a kind of 2 ribbon steel finishing mill dephosphorization systems, respectively establishes a dephosphorization point before No. 1 flat roll finishing mill and No. 1 edger roll finishing mill, improves phosphor-removing effect, solves Problems existing in background technology.
The technical solution of the utility model is:
A kind of 2 ribbon steel finishing mill dephosphorization systems, comprise No. 1 flat roll finishing mill, dephosphorization case one, No. 1 edger roll finishing mill, dephosphorization case two, roughing mill, water under high pressure pipeline, bypass water pipe and dephosphorization equipment, dephosphorization case two is located between roughing mill and No. 1 edger roll finishing mill, dephosphorization case one is located between No. 1 edger roll finishing mill and No. 1 flat roll finishing mill, dephosphorization case two-way is crossed high-pressure water pipe road and is connected with dephosphorization equipment, bypass water pipe one end and water under high pressure pipeline connection, the other end is connected with dephosphorization case one, described dephosphorization case one inside is provided with upper hose two and downcomer two, upper hose two and downcomer two are respectively equipped with multiple high pressure nozzle two, described dephosphorization case two inside is provided with upper hose one and downcomer one, upper hose one and downcomer one are respectively equipped with multiple high pressure nozzle one.
Dephosphorization case three is also provided with before described roughing mill.
Adopt the utility model, in ribbon steel is produced, first rolled piece removes the thick and raw iron scale of hard stove by the dephosphorization point that arranges before roughing mill and dephosphorization case three, removed the secondary iron scale on rolled piece surface again by two finishing mill dephosphorization points arranging between roughing mill and No. 1 edger roll finishing mill, between No. 1 edger roll finishing mill and No. 1 flat roll finishing mill and dephosphorization case two and dephosphorization case one, decrease the strip quality problem caused because iron scale press-in.
The beneficial effects of the utility model are: the capacity of equipment utilizing finish rolling dephosphorization system fully, effectively removes the thick and raw iron scale of hard stove and rolled piece surface secondary iron scale, phosphor-removing effect is good, decrease the strip quality problem caused because of iron scale press-in, ensure that product quality.
