Abstract
A tundish anti-spray device is provided and is a fire-resisting pouring object with an open-ended square top whose overall look is a container; a wavy concave-convex face with an inward opening at the and an excessive penetration is arranged at the bottom of inside the utility model, making the area of the opening smaller than that of the bottom; handles are arranged on both sides of the container for easing the installation and replacement. The adoption of the inter-shock anti-spray device is effective in controlling the flow speed of the molten steel, and the splash of the molten steel can be prevented, and the eddy flow of the molten steel can be suppressed, thereby increasing the purity of the molten steel; Besides, the utility model has the advantages of a low manufacturing cost, capacity of saving a plurality of energy, convenient installation and utilization, and benefit for popularization.
Description
Affiliated technical field
The utility model relates to a kind of molten steel speed that reduces in metallurgy industry, prevent that molten steel from splashing, the device of control molten steel turbulent flow.
Background technology
The continuous casting tundish of steel-making industry is when work, molten steel in the ladle constantly flows in the tundish, because its huge heat energy and kinetic energy impact, not only can produce serious molten steel splash phenomena, the safety that is unfavorable for the metallurgical operations workman, also can produce serious molten steel turbulent flow phenomenon, make the quality of molten steel reduce, also shorten the service life of tundish equipment.At present, the impact that people generally adopt shock plate to bear molten steel at smelting iron and steel continuous casting tundish impact zone, but owing in use exist shock plate come-up and bottom to dash the accident potential of wearing, and can not effectively solve the problem that molten steel splashes.Recently, people have also invented a kind of impact bucket, this impact bucket is a three-dimensional container, solve shock plate come-up and bottom to a certain extent and dashed the problem of wearing, but the molten steel problem of splashing still exists when continuous casting is drawn high speed, and molten steel turbulent flow problem is still serious, and it need consume more steel when making, make cost higher, install and use all inconveniences.
Summary of the invention
In order to solve the deficiency of existing shock plate and impact bucket, the utility model provides a kind of tundish to impact anti-splash device, and this device can not only prevent the shock plate come-up and prevent that the tundish bottom from towards wearing, also having efficiency to control molten steel and splashing, suppress the molten steel turbulent flow.
The technical scheme that its technical problem that solves the utility model adopts is: the big Baogang molten steel impact zone in the tundish bottom is settled an impact anti-splash device, this device is the magnesia refractories pouring piece, it is a three-dimensional container, inside bottom surface undulate at this device is concavo-convex, and the opening part of device is anti-mouthful of inside design.When the molten steel in the big Baogang enters tundish, to at first enter in this impact anti-splash device, can stop the impact of molten steel to tundish, prolonged the service life of tundish equipment, molten steel will constantly be gone up current downflow along the corrugated male and fomale(M﹠F) of this bottom of device then, in this process of flowing, will consume the kinetic energy of the molten steel overwhelming majority, efficiently solving molten steel splashes, guaranteed operator's safety, along with the continuous inflow of molten steel, the molten steel that impacts in the anti-splash device constantly rises to opening part, because opening part is inwardly to be designed to anti-mouthful, make the molten steel overfall diminish, thereby further control and the flow velocity of stable molten steel, reduced the fluctuation of molten steel, molten steel just can steadily overflow from opening part like this, eliminate molten steel turbulent flow phenomenon, improved billet quality.
The beneficial effects of the utility model are, can prevent that effectively molten steel from splashing when preventing the shock plate come-up and stoping molten steel that tundish is impacted, and suppress the molten steel turbulent flow, and are simple in structure and cost is low, install and use all very convenient.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 impacts the cross-sectional structure figure of anti-splash device for the utility model tundish;
Accompanying drawing 2 impacts the plan structure figure of anti-splash device for the utility model tundish;
Code description among the figure: 1-handle; The anti-mouth that 2-is inside; 3-waveform bottom;
The specific embodiment
Should impact anti-splash device and be placed on big Baogang molten steel impact zone, molten steel directly enters in this impact anti-splash device after big Baogang comes out, the impact of molten steel is born in the bottom of this device, prevent from direct impact of tundish caused equipment damage, because bottom of device undulate concavo-convex (3), molten steel enters the back and becomes horizontal motion by movement in vertical direction, change the moment that flows at it, anti-splash device is inner can to produce certain molten steel splash phenomena impacting, but because this device is container-like, there is wall to stop around its bottom, molten steel just can not splash out, just operator's safety can have been guaranteed, in molten steel horizontal movement process because the gravity effect, molten steel will flow along the bottom, and the concavo-convex bottom of waveform will increase the resistance of molten steel, reduce its flow velocity, because the reduction of molten steel movement velocity, kinetic energy has also just reduced, molten steel just more can not produce splash phenomena like this, also played the current stabilization effect, continuous inflow along molten steel, the molten steel that impacts in the anti-splash device will get more and more, and overflows from opening part (2) until molten steel, because opening part inwardly shrinks, can further control the water level fluctuation of molten steel, tend to be steady when it is overflowed, eliminate molten steel turbulent flow phenomenon, so just can significantly improve the quality of steel billet.
Claims (3)
1, a kind of tundish impacts anti-splash device, form by refractory material casting, and be an open-topped container, it is characterized in that: this bottom of device medial surface undulate is concavo-convex, and top open part has inwardly anti-mouthful.
2, impact anti-splash device according to the described tundish of claim 1, it is characterized in that: the concavo-convex continuity that is of the waveform of bottom inside face.
3, tundish according to claim 1 impacts anti-splash device, and it is characterized in that: open top is less than the bottom, and the inner space in vertical section is " protruding " word shape.
