Abstract
The present invention relates to a kind of crystallizer, be specially adapted to the crystallizer of the horizontal caster of steel.Be characterized in before crystallizer, being equipped with a dismountable end socket device, realize purpose, not only can reduce the horizontal casting cost significantly, and drive the development of big section horizontal continuous casting technology with the big section casting blank of little eseparation ring production.
Description
The present invention relates to crystallizer, be specially adapted to the crystallizer that the horizontal caster of steel is used.
Up to now, the domestic and international used crystallizer of horizontal caster, no matter be garden base, square billet, rectangular bloom, its common feature is a strand of producing much sizes, uses the eseparation ring of onesize size.Eseparation ring costs an arm and a leg, and sharply rises with size increase price, and the eseparation ring size reaches certain size in addition, is subjected to work that processing and forming technology limits very difficult.
The present invention is intended to overcome the deficiency of above-mentioned crystallizer, and the horizontal caster crystallizer of a kind of energy with the steel of the big section casting blank of little eseparation ring production is provided.
Characteristics of the present invention are, at the front end of crystallizer an end socket device are set, and this device is by end socket (1), water inlet pipe (2), and outlet pipe (3), end socket gland (4) is formed.End socket (1) inner surface is made up of two sections conical surfaces, the installed surface cone angle of inner cone and eseparation ring (5) is 0 °-90 °, the rear cone cone angle of end socket (1) inner surface is 0 °-90 °, radius of curvature is 0-∞, rear cone port of export cross section is a garden shape, square or rectangle, this shape has determined that strand is garden base, square billet or rectangular bloom.The water inlet pipe (2) of cooling water and outlet pipe (3) are housed on the end socket gland (4) and are communicated with recirculated cooling water passage (8).The cooling water absorption is also taken away the heat that solidification of molten steel becomes the strand shell to be discharged in end socket (1).
The present invention is that a kind of practicality is wide, and is easy to use and can be with the horizontal caster crystallizer of the big section casting blank of little eseparation ring production, and it can reduce the strand cost significantly.Example: 150 yuan/of ∮ 90 eseparation rings, 250 yuan/of ∮ 120 eseparation rings, 300 yuan/of ∮ 14 eseparation rings, 900 yuan/of ∮ 200 eseparation rings, enforcement of the present invention can be created considerable economic, and can promote the development of big section horizontal continuous casting technology.
Fig. 1, the profile of crystallizer.
Describe crystallizer detail and the working condition that proposes according to the present invention in detail below in conjunction with Fig. 1.
This crystallizer is at dismountable end socket device of former crystallizer (9) front-end configuration, this end socket device comprises end socket (1), end socket (1) radially, axial location is connected with crystallizer (9) by end socket gland (4) with bolt (10), eseparation ring (5) and mold gap (6) radially, axial location is connected with end socket gland (4) by mouth of a river gland (7) with bolt (11).The inner surface of end socket (1), constituting inner cone by the two sections conical surfaces in front and back is that the installed surface cone angle of eseparation ring (5) is 10 °, and rear cone is a molten steel channel, and radius of curvature is 80mm.The outer surface of end socket (1), by preceding, in, the three sections compositions in back, leading portion and end socket gland (4) inner surface constitute the circulation road (8) of cooling water, the stage casing is a sealing surface, back segment is the installed surface between end socket (1) and the crystallizer (9), cooling water was flowed out by outlet pipe (3) by passage (8) circulation that water inlet pipe (2) enters on end socket gland (4) in one week, absorb and take away the heat that molten steel solidification becomes the strand shell to be discharged and enter cooling water recirculation system, when high-temperature molten steel through mold gap (6), ∮ 90 eseparation rings (5) flow through and enter end socket (1) and be full of the cavity that end socket (1) inner surface forms, molten steel is frozen into the strand shell along the inner surface of end socket (1), by end socket (1) outlet cross section is that the passage of ∮ 120 enters crystallizer, finishes the overall process that the eseparation ring of ∮ 90 is produced ∮ 120 strands.
Claims (7)
1, a kind of crystallizer, the crystallizer especially for the horizontal caster of steel is characterized in that at the crystallizer front end a dismountable end socket device being housed.
