Abstract
The utility model discloses a high-pressure degreasing set of a cold-rolled steel strip. The high-pressure degreasing set comprises an alkaline liquid spraying groove, an alkaline liquid washing groove, a primary hot water spraying groove and a secondary hot water spraying groove, wherein two hairbrush rollers are respectively arranged at the two sides of the cold-rolled steel strip of the alkaline liquid washing groove. According to the high-pressure degreasing set disclosed by the utility model, spraying pressure is improved and the use amount of the hairbrush rollers is reduced; the abrasion to the cold-rolled steel strip by the hairbrush rollers is reduced and the washing effect is good; the overhauling and maintenance time of equipment is short, the production efficiency is improved and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of cleaning and degreasing device of cold-rolled steel strip, is specifically related to a kind of cold-rolled steel strip high pressure degreasing unit.
Background technology
Cold-rolled steel coils process mill milling rear surface has a large amount of iron powders, fat residue, although the major part in bell furnace heat-processed of the Residual oil on coil of strip can be volatilized, but because this volatilization process is thorough not, coil of strip surface after annealing still has carbon black and iron powder is residual, and the surface quality of cold-rolled steel coils is had a significant impact.
The structure of conventional cold-rolled steel strip high pressure degreasing unit comprises that alkali lye spray groove, alkali lye scrubs groove, heat water-spraying's groove and secondary hot water's spray groove as shown in Figure 1, and the both sides of scrubbing the cold-rolled steel strip of groove through described alkali lye are respectively equipped with 7～10 brush roll.This high pressure degreasing unit adopts 0.3Mpa spray pressure and is located at alkali lye and scrubs the degreasing cleaning that 14～20 interior brush roll of groove are carried out the cold-rolled steel strip surface, and degreasing effect depends primarily on the ability of scrubbing of brush roll.If the hairbrush roll-in is overweight, easily generation scratches to steel strip surface, and too tinge is rung degreasing effect, and is therefore high to brush roll surface hairbrush requirement, and the brush roll replacement cycle is short, and the consumptive material expense is high, has a strong impact on production kind and production cost.
Summary of the invention
The utility model purpose is to provide a kind of cold-rolled steel strip high pressure degreasing unit, reduces the usage quantity of brush roll, and cleaning performance is good, and the overhaul of the equipments service time is short, enhances productivity, and reduces production costs.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cold-rolled steel strip high pressure degreasing unit, comprise that alkali lye scrubs groove, and the both sides of scrubbing the cold-rolled steel strip of groove through described alkali lye are respectively equipped with 2～3 brush roll.
Further technical scheme, the both sides of described cold-rolled steel strip are respectively equipped with 2 described brush roll.
In technique scheme, described alkali lye is scrubbed and is provided with spray pressure in groove is the spray alkali lye of 2.5MPa.
Above-mentioned cold-rolled steel strip high pressure degreasing unit also comprises the alkali lye spray groove, and being provided with spray pressure in this alkali lye spray groove is the spray alkali lye of 0.6MPa.
Above-mentioned cold-rolled steel strip high pressure degreasing unit also comprises heat water-spraying's groove one time, and being provided with spray pressure in this heat water-spraying's groove is the spray hot water of 0.6MPa.
Above-mentioned cold-rolled steel strip high pressure degreasing unit also comprises secondary hot water's spray groove, and being provided with spray pressure in this secondary hot water's spray groove is the spray hot water of 0.6MPa.
Utilize the utility model as described below to cold-rolled steel strip high pressure skimming processes:
(1) cold-rolled steel strip enters the degreasing line from the alkali lye spray groove, and spray pressure is 0.6MPa, high pressure cleaning;
(2) scrub groove through alkali lye, spray pressure is 2.5MPa, scrubs in conjunction with 4 brush roll;
(3) again through heat water-spraying's groove, spray pressure is 0.6MPa, a hot water rinsing;
(4) finally by crossing secondary hot water's spray groove, spray pressure is 0.6MPa, and skimming processes is completed in secondary hot water's rinsing.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. the utility model improves spray pressure, reduces the usage quantity of brush roll, reduces brush roll to the wearing and tearing of cold-rolled steel strip, and cleaning performance is good, and the overhaul of the equipments service time is short, enhances productivity, and reduces production costs.
