Abstract
The utility model relates to a distributing bucket of a covering slag feeding device for continuous casting machines. The distributing bucket comprises a distributing bucket, a gravity sensor, a bracket, a hydraulic ejector rob and a PLC (programmable logic controller), wherein the bracket and the gravity sensor are arranged in the center of the bottom of the distributing bucket, the hydraulic ejector rob is arranged at one end, away from a covering slag feeding area, of the bottom of the distributing bucket, the gravity sensor is connected with the detection signal input end of the PLC through a guide line, and the control signal output end of the PLC is connected with the control end of the hydraulic ejector rob. According to the utility model, the timed and quantitative automatic feeding of covering slag of a crystallizer on a steelmaking production line can be realized through the distributing bucket arranged above the crystallizer and a feeding device, thereby solving the problem of distributing uniformity, reducing the waste of covering slag, improving the quality of steel billets, and reducing the labor intensity of operators; the distributing bucket is simpler in structure, smaller in land-occupied area and lower in cost.
Description
Technical field
The utility model relates to a kind of conticaster covering slag automatic adding device, refers to particularly a kind of cloth bucket of conticaster covering slag adding set.
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 professional on duty, according to the situation of covering slag in crystallizer, add at any time, 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 manual operation cloth is very uneven, easily cause the waste of covering slag in addition, also can cause the various mass defects of steel billet.Be badly in need of a kind of conticaster covering slag automatic adding device of design for this reason, wherein in whole device, how covering slag timing, quantitative, uniform paving applied at crystallizer molten steel surface and become a difficult problem.
Summary of the invention
The purpose of this utility model is exactly the cloth bucket that a kind of conticaster covering slag adding set will be provided, and coordinates pay-off to realize the timing of covering slag in crystallizer, quantitative, uniform distribution, alleviates site operation personnel's labour intensity simultaneously.
For achieving the above object; the cloth bucket of a kind of conticaster covering slag adding set that the utility model is designed; comprise cloth bucket, gravity sensor, support, hydraulic mandril and PLC controller; described support and gravity sensor are arranged on the bottom center of cloth bucket; described hydraulic mandril is arranged on cloth bucket bottom away from the one end of adding covering slag region; 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 hydraulic mandril.
As preferred version: described hydraulic mandril is connected by rotating shaft with the bottom of support respectively at cloth bucket.
As preferred version: by the one end away from adding covering slag region, the discharging opening to cloth bucket successively decreases the height of the sidewall of described cloth bucket.
The utility model has the advantage of: by being arranged on the cloth bucket of crystallizer top, coordinate pay-off can realize the interpolation automatically at regular time and quantity that crystallizer protecting residue on line is produced in steel-making; solved the homogeneity question of cloth; reduce the waste of covering slag; improve billet quality; alleviate operating personnel's labour intensity; cloth bucket structure is simpler simultaneously, and floor space is less, and cost is lower.
Accompanying drawing explanation
Fig. 1 is working state schematic representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1; a kind of cloth bucket of conticaster covering slag adding set; comprise cloth bucket 4, gravity sensor 5, support 7, hydraulic mandril 6 and PLC controller 9; described support 7 and gravity sensor 5 are arranged on the bottom center of cloth bucket 4; described hydraulic mandril 6 is arranged on cloth bucket 4 bottoms away from the one end of adding covering slag region; 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 hydraulic mandril 6.Described hydraulic mandril 6 is connected by rotating shaft with the bottom of support 7 respectively at cloth bucket 4.By the one end away from interpolation covering slag region, the discharging opening to cloth bucket 4 successively decreases the height of the sidewall of described cloth bucket 4.
Whole conticaster covering slag automatic adding device; also comprise the screw feeder 3 that described cloth bucket 4 tops arrange; 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 conveying flexible pipe; the charging aperture place of screw feeder 3 is provided with vibration bead 2, and in helical rotation process, constantly whirling vibration is shatter by covering slag material.The control signal output of described PLC controller 6 is also connected with the control end of pusher drive motors 5.The feeding outlet of described screw feeder 3 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 is also provided with rotary encoder 11, and described rotary encoder 11 is connected with the detection signal input of PLC controller 9 by wire.
The utility model is that the device adding for the protection of 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 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 helical rotation number of turns n of screw feeder 3 and the oral area of cloth bucket down move '; and leave in the program space of PLC, treat 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 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 according to the signal of gravity sensor, determines the weight weight that effectively control drops into covering slag of feed, and its structure is simpler, easy to maintenance.
