Abstract
The invention discloses a crystallizer of an electroslag furnace, relating to important components of electroslag remelting furnaces in the metallurgical industry, in particular to the structure improvement of the crystallizer of the electroslag furnace. The invention provides the crystallizer of the electroslag furnace, which has the advantages of difficult deformation and long service life. The crystallizer comprises a shell and an inner barrel; a cooling water jacket is arranged between the shell and the inner barrel; and the cooling water jacket is respectively communicated with a water outlet groove at the upper end of the shell and a water inlet groove at the lower end of the shell. The crystallizer of the electroslag furnace is characterized in that a strengthening rib is arranged between the water outlet groove and the water inlet groove outside the inner barrel.
Description
Technical field:
The present invention relates to the vitals of metallurgy industry electroslag remelting furnace, more particularly, relate to the improvement of crystallizer for electroslag furnace structure.
Background technology:
Mold is the most important parts of electroslag remelting furnace, and electrode melting, molten metal melting and crystallization and ingot casting moulding are all accomplished in mold, and mold also plays a part the working chamber simultaneously.Crystallizer for electroslag furnace divides by shape, mainly can be divided into circle, square and special-shaped three types.Crystallizer for electroslag furnace is processed by mild steel shell and red copper inner core assembly welding, and the failure mode of crystallizer for electroslag furnace mainly contains distortion and beats two kinds of arcs.Because the mold of mold generally is welded into by copper coin; The hardness and the intensity of copper coin itself are lower; In the heat effect of use because of molten metal and slag, cause the softening and bigger thermal stresses of inner core, finally cause the mold distortion; Work-ing life of mold has been shortened in the normally demoulding of ingot casting.
At present, both at home and abroad more adopt the thickness that increases copper coins, adopt expansion joint on the containment structure, between shell and inner core welded reinforcement and outer tube face down bonding connect the distortion that mode such as rib reduces crystallizer for electroslag furnace.The thickness that increases copper coin has increased the production cost of mold on the one hand, has weakened the capacity of heat transmission of mold on the other hand, influences the result of use of mold, makes the interior ingot structure of mold become thick, has reduced the quality of ingot casting.Above-mentioned alternate manner also acts on limited.
Summary of the invention:
The present invention is exactly to the problems referred to above, and a kind of crystallizer for electroslag furnace of not yielding, long service life is provided.
For realizing above-mentioned purpose; The present invention adopts following technical scheme; The present invention includes shell and inner core; Be watercooling jacket between shell and the inner core, watercooling jacket communicates respectively with the effluent trough of the upper end of shell, the inlet flume of lower end, is provided with stiffening web between the effluent trough outside its structural feature inner core, the inlet flume.
Beneficial effect of the present invention:
Because inner core of the present invention is outside equipped with stiffening web; Make mold not yielding, not only guarantee the normal demoulding of ingot casting, and prolonged the work-ing life of mold.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is leaf structure of mould synoptic diagram;
Fig. 4 is the B-B sectional view of Fig. 3;
Fig. 5 is the C-C sectional view of Fig. 3.
Embodiment:
The present invention includes shell 3 and inner core 6, is watercooling jacket 2 between shell 3 and the inner core 6, and watercooling jacket 2 communicates respectively with the effluent trough 7 of the upper end of shell 3, the inlet flume 1 of lower end, is provided with stiffening web 4 between the effluent trough 7 outside the inner core 6, the inlet flume 1.
Stiffening web 4 is by constituting with inner core 6 vertical horizontal gussets; Can guarantee further that mold is indeformable.
Can above the stiffening web 4, below shell 3 on be respectively arranged with cooling trough 5, cooling trough 5 communicates with watercooling jacket 2, can further strengthen the cooling inner core 6 effect.
Can in the cooling trough 5 of special-shaped crystallizer, be provided with the baffle plate 9 that parallels with inner core 6, baffle plate 9 is fixed on the support plate 8 of shell 3; The water of cooling trough 5 has sufficient contact with inner core 6 walls so that flow through, and makes inner core 6 obtain better radiating effect.
