Abstract

The utility model discloses an electromagnetic stirring roller for continuously casting plate blanks, which is composed of a wire guiding chamber, a water chamber, a bearing chamber, an installing chamber, a water inlet and a water outlet. A sleeve cylinder in the installing chamber is fixedly connected with a connecting axle and the inner part is provided with an electromagnetic stirrer. A coil of the two-phase winding without a joint and an iron core of the stirrer are fixed on a support axle with a nozzle. A guiding out wire of the two-phase winding is respectively wound in the water chamber to be connected with a wire connecting terminal to enter the wire guiding chamber to connect with an outward guiding wire. One end of the support axle is provided with an axle bumper. The utility model enables the plate blank to obtain high isometric percent crystallizing rate, few bright band negative segregation, low energy consumption and convenient installation and maintenance.

Description

Sheet billet continuous casting electromagnetic agitation roller
The utility model relates to a kind of device used in the continuous casting of metal technology.
In sheet billet continuous casting is in the past produced, do not adopt magnetic stirrer mostly.The adopter then is arranged on agitator the back of three nonmagnetic backing rolls of two cold-zones, and away from strand, so magnetic stirrer must have very big power just can make the molten steel motion; If will save material, reduce cost and adopt short coil arrangement, be difficult to obtain bigger stirring scope again.In addition, the slab two sides all needs firm support, and this just brings certain difficulty for the installation of agitator and maintenance.
The purpose of this utility model provides a kind of with the electromagnetic agitation roller of electromagnetic agitation apparatus in high strength, non-magnetic stainless steel backing roll.
The utility model is by lead-in wire chamber 2, hydroecium 3, bearing chamber 6, installation room 12 and splitting at the water inlet 1 at two ends and discharge outlet 13 is formed, installation room 12 middle sleeves 10 utilize the affixed coupling spindle 9 of bolt, magnetic stirrer 11 is installed in its inner space, the agitator that does not rotate keeps the iron core pole-face parallel with casting billet surface by key piece 5,3-7 sections coils 17 of the iron core 16 of agitator 11 and two-phase non junction winding all are fixed on the back shaft 19 that has nozzle 18, every phase winding is a lead, the lead-out wire of two phase windings is drawn from the centre bore 20 at back shaft 19 two ends, and behind knot, be connected on the binding post 21 that has polarity for 3 li at hydroecium respectively, enter lead-in wire chamber 2 again and connect outer lead 14, one end of back shaft 19 is provided with axle bumper 4, be two semi-rings, move axially to prevent magnetic stirrer 11.
Adopt water cooling to reduce the conduction heat of strand and the winding heating of magnetic stirrer itself in concrete the production.For solving Insulation Problems, the utility model has adopted polyamide-fluorine 46 laminated film sintering lines (withstand voltage 7.25KV in the water did not have flashover in 1 minute) to do winding conducting wire.For when obtaining to require sizable insulaion resistance, guarantee each coil around to and arrange, on the coil technique for coiling, every phase winding of magnetic stirrer is directly with a lead coiled non junction structure, removed the drawback that wire insulation suffers artificial destruction from; With whole magnetic stirrer vacuum paint dipping three times, adopt the imines epoxy-based lacquers that water resistance is good, mechanical strength is high simultaneously.The dried agitator of dipping lacquer is put into water and was done the power frequency breakdown strength in 24 hours and be not less than 12.8KV (1 minute).Therefore the insulaion resistance of winding increases corresponding doubling of time between overhauls(TBO) greatly.
Agitator in this electromagnetic agitation roller, two-phase non junction winding inserts 2-8Hz, the two-phase power supply that phase difference is 90 °, the electric current of two phase windings has formed an axial travelling-magnetic-field, coil around mutually and arrange and make its magnetic field energy pass the strand width and cause that molten steel in the molten bath produces continuous part and stirs, cause " butterfly " to flow, its direction is vertical with casting direction, and is parallel with wide of strand.Process is stirred and analyzes without the slab that stirs, and the slab that stirred has a significantly wide and thin crystal region that waits, and the width of crystal region can reach 60% (degree of superheat is 30 ℃) of slab thickness.By the white band negative segregation that stirring causes, all lighter than other type electromagnetic agitation, improved slab quality.
Magnetic stirrer will be set in backing roll, the sleeve technology that plays the backing roll effect is required just quite harsh, be that it must be high strength, non-magnetic stainless steel, the wall thickness of sleeve must be resisted again and live powerful ferrostatic pressure and plastic deformation does not take place, in order to prolong the service life of backing roll, must limit simultaneously because bending and the crackle that thermal stress produces.The optimum chemical composition of the utility model middle sleeve is: carbon C content is less than 0.08%, silicon Si content is less than 1.0%, manganese Mn content is less than 2.0%, aluminium Al content is less than 0.35%, chromium Cr content is 13.5-16%, nickel content is 24-27%, and titanium Ti content is 1.9-2.35%, and molybdenum Mo content is 1.0-1.5%.This prescription can guarantee that sleeve has optimum physical properties.
Magnetic stirrer of the present utility model is very near apart from strand, is obtaining under the situation of same mixing effect, and power reduces greatly, not only economy but also be easy for installation and maintenance.
Further specify below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of magnetic stirrer in the utility model
Fig. 3 is five sections coils of two phase windings of magnetic stirrer and arranges schematic diagram
Among the figure, 1 water inlet, lead-in wire chambers 2,3 hydroeciums, 4 axle bumpers, 5 key pieces, 6 bearing chambers, 7,8 sealing rings, 9 coupling spindles, 10 sleeves, 11 magnetic stirrers, 12 installation rooms, 13 discharge outlet, 14 outer leads, 15 packing rings, 16 iron cores, 17 coils, 18 nozzles, 19 back shafts, 20 centre bores, 21 binding posts.
The electromagnetic agitation roller is lifted on the continuous casting machine fan-shaped segment by the installation screw of bearing chamber, cooling water is crossed space between agitator and the rotational sleeve by water inlet by the nozzle flow of back shaft, after two phase windings and sleeve (backing roll) cooling, flow out from delivery port, form closed circuit water circulation with outer water channel.Axial employing " O " type silicon rubber loop 8 and " V " type silicon rubber loop 7 in the utility model seal, and enter in the bearing to prevent cooling water; Each end face adopts asbestos rubber packing ring 15 and adds fluid sealant and seals.
