Description
Technical field
The present invention relates to that conticaster stopper rod organization is cooling, protector.
Background technology
Conticaster stopper rod organization is controlled by the molten steel flow in middle water-coating port inflow crystallizer.Plug rod mechanism comprises stopper, crossbeam, main shaft, servomotor, frame; Crossbeam one side is connected with main shaft, opposite side is connected with the stopper top, it is inner that stopper is located at middle bag, the bowl section of the bottom of stopper and middle water-coating port joins, servomotor is controlled the movement of main shaft, and main shaft moves it by crossbeam and passes to stopper and control the bowl section exposure level of stopper bottom and middle water containing opening and control the molten steel that flows out in water-coating port therefrom; Main shaft, servomotor are connected with frame, and frame is wrapped during whole plug rod mechanism is fixed in.Because liquid liquid steel temperature in middle bag is very high, the heat that molten steel gives out such as untimely leaving will affect the job stability of plug rod mechanism, will cause plug rod mechanism to quit work when serious, affect the normal production schedule.
At present, below the frame of plug rod mechanism, cooling air port is set, cooling air port connects cooling duct, by the cold wind in cooling duct, the parts such as main shaft, servomotor is carried out coolingly, is used for guaranteeing that main shaft, motor and related components avoid the impact of molten steel heat.But because cooling air port is positioned at frame lower, its cooling effect can't cover whole plug rod mechanism, the heat that molten steel distributes easily gathers top, top heat dispersion corresponding to frame and related components is poor, easily cause stopper rod mechanism too high because of upper temp in casting cycle, the situations such as mechanical jam or electric elements fault occur, produce thereby impact is normal.Further, when the molten steel in middle bag enters crystallizer by the outflow of the mouth of a river, its underpart, the heat that molten steel distributes will produce heat radiation to plug rod mechanism, reduce the radiating effect of plug rod mechanism, affect its normal use.In addition, plug rod mechanism being carried out when cooling, because temperature difference influence can produce some water droplets, these water droplets will affect the effect of covering slag as dripping when the covering slag that is used for dropping in crystallizer; When working due to plug rod mechanism simultaneously, the as easy as rolling off a log covering slag that is positioned at the below that blows away of plug rod mechanism air-out causes the waste of covering slag.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide that conticaster stopper rod organization is cooling, protector, strengthen on the one hand the cooling itself effect of plug rod mechanism, effectively stop on the other hand heat that molten steel distributes for the heat radiation of plug rod mechanism, improve the stability of plug rod mechanism work.
Conticaster stopper rod organization protector by providing is provided, prevents that in the plug rod mechanism course of work, air-out and cooling range produce water droplet for the impact of protection slag.
To achieve these goals, the technical solution used in the present invention is:
Described conticaster stopper rod organization is cooling, protector, described conticaster stopper rod organization comprises frame, main shaft, crossbeam, stopper, servomotor, described main shaft is connected with frame, described crossbeam one side is connected with the stopper top, opposite side is connected with the main shaft top, servomotor is connected with frame, and the output of servomotor is connected with main shaft; Described conticaster stopper rod organization is connected with middle bag by frame; Middle clad is passed in the stopper bottom, and to stretch into middle bag inner and join with middle water-coating port top; Be provided with lower cooling air port in frame lower, lower cooling air port is connected with cooling tube; Cooling air port on upper rack is provided with, upper cooling air port is connected with cooling tube; Be provided with protective plate in described plug rod mechanism bottom, described protective plate is connected with middle bag.
