Abstract
The utility model discloses an electric slag furnace crystallizer, which relates to an important component of an electric slag remelting furnace in the metallurgical industry, in particular to an improvement of an electric slag furnace crystallizer structure. The utility model provides an electric slag furnace crystallizer which is less susceptible to deform and has long service life. The utility model comprises an outer housing and an inner barrel, wherein, a cooling jacket is arranged between the outer housing and the inner barrel, the cooling jacket is communicated with a water outlet groove at the upper end of the outer housing and a water inflow groove at the lower end thereof respectively, and the structure key point is that a strengthening rib is arranged between the water outlet groove and the water inflow groove outside the inner barrel.
Description
Technical field:
The utility model relates to the vitals of metallurgy industry electroslag remelting furnace, more particularly, relates to the improvement of crystallizer for electroslag furnace structure.
Background technology:
Crystallizer is the most important parts of electroslag remelting furnace, and electrode melting, molten metal melting and crystallization and ingot casting moulding are all finished in crystallizer, and crystallizer 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 classes.Crystallizer for electroslag furnace is made 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 crystallizer 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, softening and the bigger thermal stresses that causes inner core, finally cause the crystallizer distortion, work-ing life of crystallizer 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 crystallizer on the one hand, has weakened the capacity of heat transmission of crystallizer on the other hand, influences the result of use of crystallizer, makes the interior ingot structure of crystallizer become thick, has reduced the quality of ingot casting.Above-mentioned alternate manner also acts on limited.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of crystallizer for electroslag furnace of not yielding, long service life is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises shell and inner core, it between shell and the inner core watercooling jacket, 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.The beneficial effects of the utility model:
Because the utility model inner core is outside equipped with stiffening web; Make crystallizer not yielding, not only guarantee the normal demoulding of ingot casting, and prolonged the work-ing life of crystallizer.

Embodiment:
The utility model comprises 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 crystallizer 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 be provided with the baffle plate 9 that parallels with inner core 6 in the cooling trough 5 of special-shaped crystallizer, 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.
