Background technology
Along with the continuous development of society, continuous casting process has replaced conventional die castings technology gradually and in steel mill, has been widely used.But there is ingot casting cooling problem always, causes the ingot production qualification rate lower.It is not enough that the one of the main reasons that the production qualification rate is low is exactly undercooling or cooling; And the factors such as state labile that exist cooling water inflow to be difficult to control and cool off directly cause the ingot casting crystallization effect bad; Influence the quality of ingot casting, in addition, because steel billet is when just being shaped; Responsive to the unequal ten minutes of temperature; Accidentally will make ingot casting become and scrap material, bring unnecessary economic loss, so we are badly in need of a kind of cooling device for conticaster that can regulate cooling water inflow according to temperature automatically to enterprise.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The utility model content
The technical problem that the utility model will solve is: the deficiency that is directed to prior art; Provide a kind of light section continuous-casting of steel billet machine to regulate cooling device automatically; This light section continuous-casting of steel billet machine is regulated cooling device automatically makes the control of cooling confluent extremely convenient; Thereby improved the quality of conticaster ingot casting effectively, made the crystallisation by cooling better effects if of ingot casting, the quality of ingot casting can effectively be guaranteed.
For reaching the foregoing invention purpose, the technical scheme that the utility model adopted is: provide a kind of light section continuous-casting of steel billet machine to regulate cooling device automatically, comprise crystallizing wheel and cooling device; It is characterized in that: said cooling device comprises Outer Tube, water cooled pipeline, water-cooled nozzle, atomization conduit, atomizer, first by-pass valve control, second by-pass valve control, temperature sensor, display unit and programmable logic controller (PLC); Said water cooled pipeline and atomization conduit all are arranged on Outer Tube inside; Said water-cooled nozzle is arranged on the water cooled pipeline, and atomizer is arranged on the atomization conduit, and water-cooled nozzle and atomizer all stretch out Outer Tube; Said water cooled pipeline water inlet end is connected with first by-pass valve control; Said atomization conduit water inlet end is connected with second by-pass valve control; Said programmable logic controller (PLC) is connected with second by-pass valve control with first by-pass valve control respectively; Said temperature sensor is arranged on the Outer Tube, temperature sensor and display unit wireless connections; Said display unit is connected with programmable logic controller (PLC).
Further, said temperature sensor is an infrared temperature sensor.
Further, said water-cooled nozzle and atomizer delivery port place are provided with filter.
Further, said water-cooled nozzle and atomizer equate to the distance of crystallizing wheel.
In sum, the light section continuous-casting of steel billet machine that the utility model provided is regulated cooling device automatically and is had following advantage than prior art:
1, regulate first by-pass valve control and second by-pass valve control through programmable logic controller (PLC) intelligence, the confluent of control water cooled pipeline and atomization conduit makes that the control of cooling confluent is very convenient.
2 and working method multiple selection is arranged; Water-cooled or atomizing cooling separately also can both ejection water smokes of working simultaneously, thereby have improved the inherence and the surface quality of casting blank of continuous casting machine effectively; Make the crystallisation by cooling better effects if of ingot casting, the quality of ingot casting can effectively be guaranteed.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done and to be described in detail:
As shown in the figure, this light section continuous-casting of steel billet machine is regulated cooling device automatically, comprises crystallizing wheel 1 and cooling device; Said cooling device comprises Outer Tube 21, water cooled pipeline 22, water-cooled nozzle 23, atomization conduit 24, atomizer 25, first by-pass valve control 27, second by-pass valve control 28, temperature sensor 26, display unit 29 and programmable logic controller (PLC) 30; Said water cooled pipeline 22 all is arranged on Outer Tube 21 inside with atomization conduit 24; Said water-cooled nozzle 23 is arranged on the water cooled pipeline 22, and atomizer 25 is arranged on the atomization conduit 24, and water-cooled nozzle 23 is all stretched out Outer Tube 21 with atomizer 25; Said water cooled pipeline 22 water inlet ends are connected with first by-pass valve control 27; Said atomization conduit 24 water inlet ends are connected with second by-pass valve control 28; Said programmable logic controller (PLC) 30 is connected with second by-pass valve control 28 with first by-pass valve control 27 respectively; Said temperature sensor 26 is arranged on the Outer Tube 21, temperature sensor 26 and display unit 29 wireless connections; Said display unit 29 is connected with programmable logic controller (PLC) 30.
Preferably, said temperature sensor 26 is infrared temperature sensors; Said water-cooled nozzle 23 is provided with filter with atomizer 25 delivery port places; Said water-cooled nozzle 23 equates with the distance of atomizer 25 to crystallizing wheel 1.
Operation principle: after ingot casting got into crystallizing wheel 1, infrared temperature sensor 26 temperature sensors on the Outer Tube 21 changed, and temperature signal is radioed to display unit 29, and display unit 29 is connected with programmable logic controller (PLC) 30, and promptly PLC connects; Through the temperature program(me) control confluent size that configures; Regulate first by-pass valve control 27 and second by-pass valve control 28; To the confluent Based Intelligent Control in water cooled pipeline 22 and the atomization conduit 24, ingot casting in the crystallizing wheel is carried out cooling processing through water-cooled nozzle or atomizer.Selecting working method according to the temperature program(me) that configures, can be independent water-cooled or atomizing cooling, can also be that both work simultaneously, thereby improve the inherence and the surface quality of casting blank of continuous casting machine effectively, makes the crystallisation by cooling better effects if of ingot casting.
In sum; The light section continuous-casting of steel billet machine that utilizes the utility model to provide is regulated cooling device automatically makes the control of cooling confluent very convenient; Thereby the inherence and the surface quality of casting blank of continuous casting machine have been improved effectively; Make the crystallisation by cooling better effects if of ingot casting, the quality of ingot casting can effectively be guaranteed.
Though describe in detail in conjunction with the specific embodiment of accompanying drawing, should not be construed as qualification to the protection domain of this patent to the utility model.In the described scope of claims, various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
