Abstract
The utility model belongs to an improved secondary-cooling support guiding device in a secondary cooling zone below a continuous casting crystallizer for casting steel and particularly relates to a fixing sleeve for a continuous casting secondary-cooling guide supporting roller. The fixing sleeve is characterized in that a support roller shaft is mounted through symmetrical support roller bases; a support roller is mounted on the support roller shaft; and support roller fixing sleeves are respectively mounted on two sides of the support rollers and the support roller shaft between the symmetrical support roller bases. According to the fixing sleeve disclosed by the utility model, the reasonability in structure is obtained; the axial movement of the support roller can be prevented; the uniformity in continuous casting cooling is ensured; the wear to the wheel edge of the support roller can be prevented; and the service life of the support roller is prolonged.
Description
Technical field
the utility model belongs to the improvement, particularly continuous casting two cold guided bearing roller fixed cover of cast steel continuous cast mold below secondary cooling zone two cold bearing guiding device.
Background technology
molten steel gets into secondary cooling zone after in crystallizer, cooling off and forming initial solidification shell, further cools off, solidifies.Two cold bearing guiding device are positioned at the below of crystallizer, are used to support by crystallizer pull out the continuous casting billet that does not solidify fully, guide continuous casting billet steadily to move along curved line simultaneously.When sending dummy ingot, also can play the effect of supporting guiding.
two cold bearing guiding device are made up of supporting roller base, backing roll, axle.
Backing roll does not have fixed cover in
continuous casting production process, unavoidably moves axially, and drive continuous casting billet and move axially, the one, cause the continuous casting billet inhomogeneous cooling even, the 2nd, supporting roller wheel is along easy abrasion, and the life-span reduces.
Summary of the invention
The purpose of
the utility model is to provide a kind of continuous casting two cold guided bearing roller fixed cover; It is rational in infrastructure, can prevent that backing roll from moving axially, and guarantees the continuous casting billet cooling evenly; Can prevent supporting roller wheel along wearing and tearing, prolong the service life of backing roll.
The purpose of
the utility model is achieved in that a kind of continuous casting two cold guided bearing roller fixed cover; Comprise that the supporting roller base through symmetry is installed with supporting roller; Backing roll is installed on supporting roller, on the supporting roller between the supporting roller base of backing roll both sides and symmetry, the backing roll fixed cover is installed respectively.
the utility model is fixed backing roll owing on the supporting roller between the supporting roller base of backing roll both sides and symmetry, the backing roll fixed cover is installed respectively, can not move axially.After the backing roll both sides installed fixed cover additional, backing roll moved axially, long service life.The utility model is rational in infrastructure, has prevented that backing roll from moving axially, and makes the continuous casting billet cooling evenly, and has prevented the wearing and tearing on supporting roller wheel edge, has prolonged the service life of backing roll.
Description of drawings
below will combine accompanying drawing that the utility model is done further to describe, and accompanying drawing 1 is the sectional structure sketch map of the utility model.
The specific embodiment
a kind of continuous casting two cold guided bearing roller fixed cover; Shown in accompanying drawing 1; Comprise that the supporting roller base 1 through symmetry is installed with supporting roller 3; Backing roll 2 is installed on supporting roller 3, on the supporting roller 3 between the supporting roller base 1 of backing roll 2 both sides and symmetry, backing roll fixed cover 4 is installed respectively.Backing roll fixed cover 4 and supporting roller 3 are movingly.
Claims (2)
1. continuous casting two cold guided bearing roller fixed cover; Comprise that the supporting roller base (1) through symmetry is installed with supporting roller (3); Backing roll (2) is installed on supporting roller (3), it is characterized in that: be positioned at backing roll (2) both sides and the symmetry supporting roller base (1) between supporting roller (3) on backing roll fixed cover (4) is installed respectively.
2. continuous casting two cold guided bearing roller fixed cover according to claim 1 is characterized in that: backing roll fixed cover (4) and supporting roller (3) are movingly.
