Description
Technical field
This utility model relates to metallurgy industry, specifically belongs to a kind of intermediate frequency furnace coil cooling water Online Monitoring Control System。
Background technology
At present, intermediate frequency furnace is widely used in metallurgy industry, in use needs induction coil is circulated water-cooled but, to take away the heat produced in molten steel fusion process, it is ensured that the normal operation of induction coil。But in most intermediate frequency furnace use procedures, the especially small intermediate frequency induction furnace used by scientific research institutions and laboratory, the design of coil cooling water recirculation system is simple, there is potential safety hazard。Only at water inlet pipe, Pressure gauge is installed during installation equipment and shows intake pressure, when pipeline between induction coil or induction coil and Pressure gauge occurs to block for various reasons, Pressure gauge still can show that hydraulic pressure is normal, technical staff is made to think circulation normal operation by mistake, as processed not in time, cooling water circulation interruption in induction coil, under high temperature, molten steel heat cannot be passed rapidly and take away, it is very easy to scorch induction coil, thus bleed-out occurring and causing blast, cause damage and personnel's injury of equipment。
Utility model content
This utility model is for shortcoming of the prior art, it is provided that a kind of by monitoring induction coil Inlet and outlet water flow in real time and temperature realizes the safety control system of induction coil and operator。
This utility model adopts the following technical scheme that:
A kind of intermediate frequency furnace coil cooling water Online Monitoring Control System, it is characterized in that, described system is to install the first water temperature tester (4) and the first electromagnetic flowmeter (3) with induction coil (2) on the inlet pipeline that cooling water tank (1) connects, and installs the second water temperature tester (6) and the second electromagnetic flowmeter (5) with cooling water tank (1) on the water return pipeline that induction coil (2) connects；Described second electromagnetic flowmeter (5) signal output part installs flux lower limit alarm device (electric bell)。
Preferably, described first water temperature tester (4), the second water temperature tester (6) are BRT-XT1A temperature measuring device；It is LDG-MK electromagnetic flowmeter that first electromagnetic flowmeter (3), the second electromagnetic flowmeter (5) are model。
The beneficial effects of the utility model: adopt system of the present utility model can effectively control stablizing of induction coil heat exchange amount in fusion process, save the energy, hence it is evident that extension coil service life, improve the security protection ability of equipment and personnel。
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model。
Detailed description of the invention
Below in conjunction with accompanying drawing 1, this utility model is described in further detail:
From Fig. 1, whole system includes cooling water tank 1, induction coil 2, cooling water tank 1 connects with induction coil 2, the inlet pipeline that cooling water tank 1 connects with induction coil 2 is installed the first water temperature tester 4 and the first electromagnetic flowmeter 3, the water return pipeline that induction coil 2 connects with cooling water tank 1 is installed the second water temperature tester 6 and the second electromagnetic flowmeter 5。At the second electromagnetic flowmeter 5, flux lower limit alarm device is installed。By the feedback of the second electromagnetic flowmeter 5, accurately judging that whether water route is unobstructed, if the flow of the second electromagnetic flowmeter 5 is close to the flux lower limit position set, alarm device (such as electric bell) automatic alarm, control system is automatically obtained power-off according to alarm signal feedback。Technical staff shows that according to power-off manually opening emergent water route promptly cools down induction coil, it is ensured that equipment, personal security。Wherein first water temperature tester the 4, second water temperature tester 6 is BRT-XT1A temperature measuring device。Wherein first electromagnetic flowmeter the 3, second electromagnetic flowmeter 5 is model is LDG-MK electromagnetic flowmeter。
The above electromagnetic flowmeter, temperature measuring device feedback signal are attached to operating board computer control system by control line and show in real time, and control system can realize following two big functions:
1) according to the given heat exchange amount of different steel grade fusion process and the Inlet and outlet water temperature that real-time monitors, it is automatically adjusted water inlet pipe electromagnetic flowmeter flow, keeps the stability of intermediate frequency (IF) smelting process heat transmission。
Theoretical foundation: Q=Ak (T2-T1)
In formula: Q is heat exchange amount, A be heat exchange area, k is copper crystallizer heat conductivity, T2For water outlet temperature, T1For Inlet water temperature。
2) by the display of outlet pipe effusion meter numeral and feedback, accurately judging that whether water route is unobstructed, as effusion meter flow indication exceedes flux lower limit, alarm device automatic alarm, control system is automatically obtained power-off according to alarm signal feedback。Technical staff shows that according to power-off manually opening emergent water route promptly cools down induction coil, it is ensured that equipment, personal security。
Adopt this system effectively to control stablizing of induction coil heat exchange amount in fusion process, save the energy, hence it is evident that extension coil service life, improve the security protection ability of equipment and personnel。
