Abstract
The utility model relates to a plate blank descaling treatment device during rough rolling of hot-rolled strip steel. The plate blank descaling treatment device comprises a front surface descaling water collecting pipe with a spray nozzle, and is characterized in that descaling water collecting pipes with the spray nozzles are arranged in the appropriate positions at the two ends of the front surface descaling water collecting pipe to enable the spray nozzles of the descaling water collecting pipes to be directed against descaling blind areas. The distances from the spray nozzles of the descaling water collecting pipes to side surfaces of hot-rolled plate blanks and the angles with the plate blanks in all the directions are determined according to the spraying angles and the blind areas of the spray nozzles of the descaling water collecting pipes. The plate blank descaling treatment device during the rough rolling of the hot-rolled strip steel, disclosed by the utility model, has the advantages and effects of eliminating the descaling blind areas formed during vertical descaling of the hot-rolled plate blanks, improving the descaling effect of the hot-rolled plate blanks, improving the surface quality of finished products, reducing the accumulation of iron oxide scales before a rough rolling machine and reducing equipment corrosion caused by oxidized slag.
Description
Technical field
When the utility model relates to a kind of hot-strip roughing, slab de-scaling treating apparatus, belong to field of metallurgical equipment.
Background technology
It is the emphasis that hot rolling steel billet must be ensured the quality of products that the slab de-scaling is processed, because slab thickness is excessive, the simple de-scaling up and down perpendicular to the base face (is called in the following text: vertical de-scaling), cause the slab side to have the de-scaling blind area of certain area, make the side de-scaling unclean, oxidizing slag invests steel slab surface, causes that the shallow top layer of semi-finished product is embedded with a certain amount of oxidizing slag after roughing system, affect next step operation rolling, have a strong impact on end product quality.
Summary of the invention
Can make the treating apparatus of slab side de-scaling when the purpose of this utility model is to provide a kind of hot-strip roughing, improve the scale removal effect of hot rolling slab, improve the surface quality of finished product.
Each is the blind area of vertical de-scaling to slab side center line in 1/3rd scopes that are about thickness by the middle part up and down, for this de-scaling blind area, installs 1 group of side descaling jet additional at former de-scaling collector pipe two ends.
The technical solution of the utility model is: during the hot-strip roughing, slab de-scaling treating apparatus comprises the upper de-scaling collector pipe with nozzle, it is characterized in that arranging in the appropriate location, two ends of upper de-scaling collector pipe the side de-scaling collector pipe with nozzle, make the nozzle needle of de-scaling collector pipe to the de-scaling blind area.
According to the width of de-scaling collector pipe nozzle spray angle and blind area determine de-scaling collector pipe nozzle from the distance of hot rolling slab 4 sides and with the angle of hot rolling slab all directions.
During hot-strip roughing of the present utility model, slab de-scaling treating apparatus has the following advantages and effect
:
The scale removal effect of hot rolling slab has been improved in the de-scaling blind area that has formed when having eliminated the vertical de-scaling of hot rolling slab, improves the surface quality of finished product; Reduce iron scale and pile up before roughing mill, reduce oxidizing slag to the corrosion of equipment.
Description of drawings
Fig. 1 is de-scaling treating apparatus structural representation of the present utility model.
Fig. 2 is the A-A cutaway view in Fig. 1.
In figure, 1-upper dephosphorization collector pipe, 2-nozzle, 3-side dephosphorization collector pipe, 4-slab cross section, 5-lower dephosphorization collector pipe, 6-slab upper surface.
The specific embodiment
As shown in the figure, during hot-strip roughing of the present utility model, slab de-scaling treating apparatus comprises the upper de-scaling collector pipe 1 with nozzle 2, side de-scaling collector pipe 3 with nozzle is set in the appropriate location, two ends of upper de-scaling collector pipe, simultaneously according to the width of de-scaling collector pipe nozzle spray angle and blind area determine de-scaling collector pipe nozzle from the distance of hot rolling slab side and with the angle of hot rolling slab all directions, make the nozzle needle of de-scaling collector pipe to the de-scaling blind area, guarantee the removal with hot rolling slab side squama after installation.
Claims (2)
1. slab de-scaling treating apparatus during a hot-strip roughing, comprise the positive de-scaling collector pipe with nozzle, it is characterized in that arranging in the appropriate location, two ends of positive de-scaling collector pipe band nozzle de-scaling collector pipe, makes the nozzle needle of de-scaling collector pipe to the de-scaling blind area.
2. slab de-scaling treating apparatus during hot-strip roughing according to claim 1, it is characterized in that according to the width of de-scaling collector pipe nozzle spray angle and blind area determine de-scaling collector pipe nozzle from the distance of hot rolling slab side and with the angle of slab all directions.
