Abstract
The utility model is related to a kind of pans impact zone safety protection structures, belong to molten steel casting apparatus field.The utility model includes the pans for connecting steel ladle and crystallizer, pans include the thermal insulation layer being arranged from outside to inside, permanent layer, working lining, the region that steel ladle molten steel is cast into pans is pans impact zone, the working lining of pans impact zone tank bottom is provided with turbulator, it is provided with shock plate immediately below turbulator, shock plate is set in permanent layer, and positioned at the position close to permanent layer upper surface.Shock plate uses magnesium refractory.The utility model increases impact resistance by the shock plate of the increase strong shock resistance in pans impact zone permanent layer, punches through the serious accident that permanent layer causes pans to wear steel after turbulator can be effectively prevent to be punched through again and occurs.
Description
Technical field
The utility model is related to a kind of pans impact zone safety protection structures, belong to molten steel casting apparatus field.
Background technology
Continuous casting technology is one and liquid metals is continuously cast into certain break through one group of special cooling and support device
The strand new process of face shape, steel ingot-breaking down work that its appearance has dominated since fundamentally changing a century
Skill.Continuous casting steel machine has simplified production process, recovery rate of iron height, energy consumption low, automatic compared with tradition is molded into steel technique
Many advantages, such as change degree is high, productivity is high, slab quality is good becomes the development of iron & steel industry weight with epoch-making property in history
Want one of technology.The exploitation of continuous casting steel machine technology is steel production relaying oxygen coverter technology great again later with application
Revolution is one of technology with fastest developing speed in the most active branch of current field of metallurgy and field of steel-making.Continuous casting technology
Huge motive force is produced to world steel industrial expansion.Continuous casting fast development at present have become promotion steel-making and it is whole
The booming major technique power of a steel production.
During continuous casting steel machine, pans are the containers for holding molten steel connected between steel ladle and crystallizer, are had
The functions such as decompression, shunting, removal of inclusions and storage molten steel, can realize sequence casting.Currently, pans internal structure generally by
It is outer to be constituted to interior predominantly thermal insulation layer, permanent layer, working lining.Pans impact zone is the area that steel ladle molten steel is cast into pans
Domain, MOLTEN STEEL FLOW speed is fast, has the function of washing away to pans impact zone tank bottom and side wall.To improve pans impact zone tank
Bottom impact resistance, improving flow field of the molten steel in impact zone prevents from washing away side wall and slag, in pans impact zone tank bottom work
Make layer and places turbulator.
Due to the continuous improvement with pans direct casting stove number, pans impact zone turbulator is by molten steel flushing time
It is long, it may appear that the phenomenon that turbulator bottom punches through causes great security risk to safety in production.
Utility model content
Technical problem to be solved in the utility model is：A kind of pans impact zone safety protection structure is provided, can be had
Effect punches through the serious accident that permanent layer causes pans to wear steel and occurs again after preventing turbulator from being punched through.
Technical solution used by the utility model is to solve above-mentioned technical problem：Pans impact zone security protection knot
Structure, includes the pans for connecting steel ladle and crystallizer, pans include the thermal insulation layer being arranged from outside to inside, permanent layer,
Working lining, the region that steel ladle molten steel is cast into pans are pans impact zone, and the working lining of pans impact zone tank bottom is arranged
There is turbulator, shock plate is provided with immediately below turbulator, shock plate is set in permanent layer.
It is further：Shock plate is disposed in proximity to the position of permanent layer upper surface.
It is further：Shock plate uses magnesium refractory.
The utility model has the beneficial effects that：By increasing rushing for strong shock resistance in pans impact zone permanent layer
Plate is hit, impact resistance is increased, punches through the evil that permanent layer causes pans to wear steel after turbulator can be effectively prevent to be punched through again
Sexual behavior thus occur.The utility model is easy to operate, and cost increase is limited, has preferable promotional value.
Description of the drawings
Fig. 1 is the pans overlook direction structural schematic diagram of the prior art；
The pans overlook direction structural schematic diagram of Fig. 2 the utility model；
Fig. 3 is the A-A structural schematic diagrams of Fig. 2；
Parts, position and number in figure：1- pans, 2- thermal insulation layers, 3- permanent layers, 4- working linings, the punching of 5- pans
Hit area, 6- turbulators, 7- shock plates, the mouths of a river 8-, 9- barricades.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in Figures 2 and 3, the utility model includes the pans 1 for connecting steel ladle and crystallizer, pans 1
Including thermal insulation layer 2, permanent layer 3, the working lining 4 being arranged from outside to inside, the region that steel ladle molten steel is cast into pans 1 is pans
The working lining 4 of impact zone 5,5 tank bottom of pans impact zone is provided with turbulator 6, is provided with shock plate 7 immediately below turbulator 6, rushes
Plate 7 is hit in permanent layer 3.Shock plate 7 is preferably disposed on close to the position of 3 upper surface of permanent layer.Shock plate 7 preferably uses magnesium
The resistance to material of matter.
When implementation, when the permanent layer 3 of pans 1 is constructed, under the directly impact just of pans impact zone molten steel Baogang stream
Shock plate 7 is placed in permanent layer 3 by side that is, immediately below turbulator 6, and close to 3 upper surface of permanent layer.
The utility model is increased by the shock plate 7 of the increase strong shock resistance in the permanent layer 3 of pans impact zone 5
Add impact resistance, punches through the pernicious thing that permanent layer 3 causes pans 1 to wear steel after turbulator 6 can be effectively prevent to be punched through again
Therefore occur.
