Abstract
The invention relates to the technical field of metallurgical continuous casting production, in particular to a casting powder automatic feeding device of a continuous casting machine. The casting powder automatic feeding device of the continuous casting machine comprises a material distributing hopper, wherein the material distributing hopper is arranged above a casting powder feeding area of a crystallizer, a helical material pusher is arranged above the material distributing hopper, a casting powder storage tank fixedly arranged on the helical material pusher, and a material outlet at the bottom of the casting powder storage tank is connected with a material inlet of the helical material pusher. The device has the advantages that by arranging the material distributing hopper above the crystallizer, the casting powder of the crystallizer is automatically fed in a fixed-time and fixed-quantity way on the steelmaking production line, the uniformity of material distributing is improved, the waste of the casting powder is reduced, the quality of steel billets is improved, and the labor strength of operators is reduced; and meanwhile, the structure is simpler, the land occupation area is less, and the cost is lower.
Description
Technical field
The present invention relates to the metallurgical continuous casting production technical field, refer to particularly a kind of conticaster covering slag automatic adding device.
Background technology
Add the covering slag placingJi Shu history of existing more than 30 year, it is to stabilizing continuous casting technique, expansion continuous casting kind, and improving slab quality and output has very important effect.The covering slag that steel-making is produced on line is all generally to adopt manual type to add, need the professional on duty, add at any time according to the situation of covering slag in crystallizer, because the reason operating environments such as covering slag airborne dust are severe, very large to personnel's actual bodily harm, labor intensity of operating staff is larger; Owing to being that the manually-operated cloth is very uneven, easily cause the waste of covering slag in addition, also can cause the various mass defects of steel billet.
Chinese utility model patent CN202845726U discloses a kind of conticaster covering slag automatic adding device; this device utilizes distributing trolley; screw feeder has been realized the automatic interpolation of covering slag in conjunction with the PLC controller plc; but this apparatus structure complexity; floor space is large, and the spending of cost is larger.
Summary of the invention
Purpose of the present invention will provide a kind of conticaster covering slag automatic adding device exactly; for realizing the timing of covering slag in crystallizer, quantitative automatic input; uniform distribution; alleviate site operation personnel's labour intensity; simultaneously than existing equipment; structure is simpler, and floor space is less, and cost is lower.
For achieving the above object; a kind of conticaster covering slag automatic adding device that the present invention is designed; comprise and be arranged on the cloth bucket that crystallizer protecting residue adds the top, district; described cloth bucket top is provided with screw feeder; the top of described screw feeder is fixedly installed the covering slag storage tank, and the bottom discharge mouth of described covering slag storage tank is connected with the charging aperture of screw feeder.
As preferred version: the feeding outlet of described screw feeder be positioned at cloth bucket central authorities directly over, the power intake of screw feeder is connected with the pusher drive motors.
As preferred version: described cloth bucket bottom center is provided with support and gravity sensor, described cloth bucket bottom is provided with hydraulic mandril away from an end of crystallizer, described gravity sensor is connected with the detection signal input of PLC controller by wire, and the control signal output of described PLC controller is connected with the control end of pusher drive motors with the control end of hydraulic mandril.
As preferred version: the power intake of described screw feeder also is provided with rotary encoder, and described rotary encoder is connected with the detection signal input of PLC controller by wire.

The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
A kind of conticaster covering slag automatic adding device as shown in Fig. 1; comprise that being arranged on crystallizer 8 covering slags adds the cloth bucket 4 of top, district; described cloth bucket 4 tops are provided with screw feeder 3; the top of described screw feeder 3 is fixedly installed covering slag storage tank 1; the bottom discharge mouth of described covering slag storage tank 1 is connected with the charging aperture of screw feeder 3 by the conveying flexible pipe; the charging aperture place of screw feeder 3 is provided with vibration bead 2, and in the helical rotation process, constantly whirling vibration is shatter by the covering slag material.Described cloth bucket 4 bottom center are provided with support 7 and gravity sensor 5, described cloth bucket 4 bottoms are provided with hydraulic mandril 6 away from an end of crystallizer 8, described gravity sensor 5 is connected with the detection signal input of PLC controller 9 by wire, and the control signal output of described PLC controller 6 is connected with the control end of pusher drive motors 5 with the control end of hydraulic mandril 6.The feeding of described screw feeder 3 outlet be positioned at cloth bucket 4 central authorities directly over, the power intake of screw feeder 3 is connected with pusher drive motors 10.The power intake of described screw feeder 3 also is provided with rotary encoder 11, and described rotary encoder 11 is connected with the detection signal input of PLC controller 9 by wire.
The present invention is that the device added for the protection of the slag material on line is produced in steel-making, adopts screw feeder 3 to realize the conveying of covering slag material.Covering slag storage tank 1, for the storage protection slag, adopts lifting mode to be fixed on higher position.System cooks up according to test and consumption calculating the covering slag consumption that different steel grades are corresponding; be converted to the frequency n that the oral area of the helical rotation number of turns n of screw feeder 3 and cloth bucket down moves '; and leave in the program space of PLC, treat the PLC system queries.For guaranteeing the uniformity of conveying, it is constant that the rotating speed of pusher drive motors 10 keeps.PLC controller 9 is down toppled over according to the signal controlling cloth bucket 4 of gravity sensor 5, and controls the angle of toppling over downwards by hydraulic mandril 6, adjusts the cloth uniformity, thereby guarantees that the covering slag uniform spreading applies on the molten steel surface of crystallizer 8.System has PLC software and hardware implementation procedure to control, and completes the actions such as automatic weighing, automatic accurate feeding, thereby determines the weight weight that effectively control drops into covering slag of feed according to the signal of gravity sensor, and its structure is simpler, easy to maintenance.
