Description

The continuous cast mold liquid level adds slag control system automatically

(1) technical field

The utility model relates to a kind of system controlled by computer charging system, and particularly a kind of continuous cast mold liquid level adds slag control system automatically.

(2) background technology

When conticaster was built square billet, crystallizer liquid steel level surface added covering slag, was most important operation during continuous casting is produced, and covering slag plays a part very important in continuous casting production, as prevented secondary oxidation, the lubricated absorption impurity etc. that reaches.Continuous casting process requires covering slag in casting cycle, to form three-deckers such as melting layer, sinter layer and slag layer, so that better play a role.

At present, the slag mode that adds of publicity is divided into manual work and mechanical device.The artificial covering slag that adds is the mode that most conticaster system adopts, and the artificial covering slag that adds receives the influence of operator's factor bigger, be difficult to guarantee the stability of adding be easy to generate volume slag and liquid fluctuating, thereby produce be mingled with, defective such as oscillation mark intensification; It is to replace the artificial blanking blanking time of interpolation covering slag at regular time and quantity through the setting mechanical device by mechanical device that mechanical device adds the covering slag mode; This mode can partly alleviate working strength of workers; But but there is serious deficiency; It still is to lean on artificial setting-up time mode at interval to adjust blanking velocity and quantity at work, can not be according to covering slag on the conticaster liquid level excessive or very few, thereby cause the quality of continuous casting square billet unstable.

Because the conticaster crystallizer surrounding environment is abominable, the workman is very big at this labor intensity, is badly in need of exploitation and can substitutes the artificial control system that adds slag automatically reliably with development one cover, to alleviate working strength of workers and the quality that improves continuous casting square billet.

(3) summary of the invention

The utility model provides a kind of continuous cast mold liquid level simple in structure, that automaticity is high to add slag control system automatically in order to remedy the deficiency of prior art.

The utility model is realized through following technical scheme:

A kind of continuous cast mold liquid level adds slag control system automatically; Comprise crystallizer; It is characterized in that: the slag blanket temperature-detecting device and the level-sensing device that connect industrial computer are installed in the said crystallizer; Special-purpose software is installed in the industrial computer, and industrial computer is connected with display control interface with control performance element, field control alarm unit respectively, control performance element respectively with add feed bin, pneumatic unit and slag charge shower nozzle and be connected.

The utility model is a cover closed loop automatic control system; It is core with the industrial computer; Come to control automatically each part group east work through special-purpose software; After basic parameter is provided with completion, carry out parameter adjustment by industrial computer is next according to the actual conditions of slag liquid level in the continuous cast mold, need not the adjustment of manual intervention again and can guarantee that all even of slag liquid level stablized in the crystallizer.

The more excellent scheme of the utility model is:

Said slag charge shower nozzle front end is provided with flat duckbilled spout, and the rear end is equipped with multi-directional regulation device, the flexible adjustment when guaranteeing to add slag, and assurance adds the uniformity of slag.

The utility model can evenly add covering slag automatically reliably; The course of work need not the manual intervention adjustment, can adjust the thickness that adds covering slag through setting control covering slag surface temperature bound, and the workman can stop and starting charging system through the controlling alarm unit at the scene; Has reinforced position in storehouse sound and light of alarm when not enough; Have the fault sound and light of alarm, have microcomputer picture complete monitoring function, have blanking data statistics and memory function.

The utility model is simple in structure, and is easy to use, reasonable in design, applying flexible, and automaticity is high, can effectively reduce labor strength, improves the quality of products, and is suitable for wide popularization and application.

(4) description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is that the system of the utility model connects sketch map;

Fig. 2 is the structural scheme of mechanism of the utility model slag charge shower nozzle.

Among the figure, 1 industrial computer, 2 slag blanket temperature-detecting devices, 3 level-sensing devices, 4 control performance elements, 5 field control alarm units, 6 display control interfaces, 7 add feed bin, 8 pneumatic units, 9 slag charge shower nozzles, 10 flat duckbilled spouts, 11 multi-directional regulation devices.

(5) specific embodiment

Accompanying drawing is a kind of specific embodiment of the utility model.This embodiment comprises crystallizer; The slag blanket temperature-detecting device 2 and level-sensing device 3 that connect industrial computer 1 are installed in the said crystallizer; In the industrial computer 1 special-purpose software is installed; Industrial computer 1 is connected with display control interface 6 with control performance element 4, field control alarm unit 5 respectively, control performance element 4 respectively with add feed bin 7, pneumatic unit 8 and slag charge shower nozzle 9 and be connected; Said slag charge shower nozzle 9 front ends are provided with flat duckbilled spout 10, and the rear end is equipped with multi-directional regulation device 11.

The surface temperature that reads slag liquid level in the crystallizer that the course of work of system is not stopped by industrial computer 1 in real time; Surface temperature like the pomace liquid level surpasses the charge temperature of setting; Then industrial computer 1 control performance element 2 lets and adds feed bin 7 blankings, opens pneumatic unit 8 simultaneously, and covering slag evenly is blown in the crystallizer by feeding gas through slag charge shower nozzle 9 in tremie pipe; And then the surface temperature of the interior slag liquid level of survey crystallizer; Still surpass the charge temperature of setting like the surface temperature of pomace liquid level, the reinforced process above then industrial computer 1 repeats is lower than the charge temperature of setting then stops reinforced and close pneumatic unit 8 if measure the surface temperature of slag liquid level in the crystallizer.
