Description
Technical field
The invention belongs to Ferrous Metallurgy continuous casting technology field, relate in particular to a kind of electromagnetic agitation water-cooling control system.
Background technology
In metallurgical production, on conticaster, use electromagnetic agitating technology, can significantly alleviate center segregation and center porosity, greatly improve equiaxial crystal ratio, substantially eliminate implosion and central pipe, improve strand qualification rate.Electromagnetic agitating technology has become a kind of important technological means of improving slab quality.Magnetic stirrer relies on the coil of energising to produce electromagnetic force and stirs molten steel, and the current strength of hot-wire coil is very large, and around liquid steel temperature is higher, needs water flowing cooling.Electromagnetic stirring cooling water system is mainly used in cooling electric magnetic stirrer coil, is the assurance of the normal operation of electromagnetic device safety, and electromagnetic agitation water-cooling control system is a most important ring in electromagnetic agitation use procedure.
The various signals (comprising temperature, electrical conductivity, discharge, pressure, pump motor major loop) that electromagnetic agitation water-cooling system sensor gathers need to, by cable directly from on-site transfer to master-control room, reach the object of controlling water-cooling system.Because pump house is on-the-spot and there is very long distance in control room, cable radical more (transmission of each signal needs a cable), and surrounding environment is severe (high temperature, high humidity, high dirt), each cable takes up room more at the scene between pump house and control room, easily damage, cause signal transmission decay, affect the proper operation of master-control room, once the water-cooling system of electromagnetic agitation breaks down, have a strong impact on whole continuous casting production working procedure.
Therefore, the communication cable wiring between pump house scene and master-control room needs a kind of simple in structure, reasonable in design, safe and reliable, installation and maintenance mode of connection easily.
Summary of the invention
The object of this invention is to provide a kind of electromagnetic agitation water-cooling control system, to overcome prior art above shortcomings.
The object of the invention is to be achieved through the following technical solutions:
A kind of electromagnetic agitation water-cooling control system, comprise the electromagnetic agitation PLC of main website system, control cabinet, thermometer, temperature sensor, flowmeter, flow sensor, pressure sensor and conductivity measurement, described control cabinet is ET200pro distributed director, in described control cabinet, comprise main loop, digital quantity input module and analog input module, described pressure sensor, temperature sensor, flow sensor and conductivity measurement are connected with control cabinet by cable, described control cabinet is connected with main website electromagnetic agitation PLC system by Profibus-DP fieldbus, described pressure sensor is connected with digital quantity input module, and described temperature sensor, flow sensor and conductivity measurement are connected with input module.
Further, described cable is ET200pro distributed director private cable.
Further, the quantity of described cable is identical with the total amount of thermometer, flowmeter, pressure sensor and conductivity measurement.
Further, described Profibus-DP fieldbus quantity is one.
Beneficial effect of the present invention is: avoided the long distance wiring of a large amount of cables, reduced that on-the-spot a large amount of wirings and sensor signal decay to control room, provided cost savings, reduced system failure rate, and reduced on-site installation work amount and maintain easily with having realized.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the workflow schematic diagram of the electromagnetic agitation water-cooling control system described in the embodiment of the present invention.
The specific embodiment
As shown in Figure 1, a kind of electromagnetic agitation water-cooling control system described in the embodiment of the present invention, comprise the electromagnetic agitation PLC of main website system, control cabinet, thermometer, temperature sensor, flowmeter, flow sensor, pressure sensor and conductivity measurement, described control cabinet is ET200pro distributed director, in described control cabinet, comprise main loop, digital quantity input module and analog input module, described pressure sensor, temperature sensor, flow sensor and conductivity measurement are connected with control cabinet by cable, described control cabinet is connected with main website electromagnetic agitation PLC system by Profibus-DP fieldbus, described pressure sensor is connected with digital quantity input module, and described temperature sensor, flow sensor and conductivity measurement are connected with input module, described cable is ET200pro distributed director private cable, the quantity of described cable is identical with the total amount of thermometer, flowmeter, pressure sensor and conductivity measurement, described Profibus-DP fieldbus quantity is one.
During concrete use, in electromagnetic agitation water-cooling system, have a lot of thermometers, each thermometer transmits into ET200pro distributed director by temperature signal by cable by temperature sensor; Each flowmeter transmits into ET200pro distributed director by cooling water flow signal by cable by flow sensor; Each pressure sensor transmits the distributed director into ET200pro by cooling water pressure force signal by cable; Each conductivity measurement transmits the distributed director into ET200pro by cooling water conductivity signal by cable; ET200pro distributed director can be controlled the keying of on-the-spot each water pump.
These signals, by ET200pro distributed director, from the on-the-spot output of pump house, import control room into through a Profibus-DP fieldbus, and corresponding control behavior, according to the signal of receiving, is made in control room.
Add after ET200pro distributed director, avoided a large amount of cables to be directly inputted to control room from pump house scene.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection scope of the present invention.
