Described dividing plate upper surface flushes with riser upper surface, and upper end surface, in same plane, makes Steel pipe mould reliably be placed on thermal insulation layer.
Described heat-insulating heat-preserving material is alumina silicate felt, or other insulation materials, as pearlite wool, phenolic foam material etc.
Described column comprises column body, lower prop and chuck, chuck is arranged on column body, lower prop junction, column body is fixed on oscillating plate, lower prop is installed in through hole corresponding to base plate, lower prop periphery cover has spring, spring upper end is stuck in chuck, and its lower end is stuck on the boss of bottom hole periphery.During vibration, lower prop moves reciprocatingly up and down in through hole, by arranging spring, reduces vibrating noise.
Be provided with water flowing chamber in described oscillating plate, its two ends arrange water inlet, discharge outlet.
Described vibrating body is pneumatic vibration body.
Compared with prior art, the beneficial effect that the utility model has is:
1, this molten steel condensation vibrator produces exciting force by vibrating body, by oscillating plate, thermal insulation layer, exciting force is passed in Steel pipe mould, make the vibrated disturbance of the molten steel in condensation process, the molten steel that the molten steel that its edge temperature is lower is high with central temperature mixes mutually, reduce or eliminate the temperature difference, make internal and external temperature consistent, ensure that crystallization process is even, thus greatly improve the shrinkage cavity phenomenon in steel ingot.
2, the molten steel in Steel pipe mould is when condensation, temperature can not decline fast, by arranging thermal insulation layer, in thermal insulation layer, loading heat-insulating heat-preserving material, avoiding the heat of Steel pipe mould to scatter and disappear downwards on the one hand, ensure heat insulation effect, avoid heat to pass to the vibrating body of below on the other hand, cause device damage, simultaneously, thermal insulation layer adopts the framework of rigidity, ensures the transmission effect to exciting force in vibration processes.
3, pass into cooling water in oscillating plate, prevent heat going down further, ensure the normal work of vibrating body.
4, by arranging spring at column leg, the noise that vibration produces is reduced.
