Abstract
The utility model relates to a liquid level automatic measuring and controlling device which is used for quick cooling jet metal thin strip equipment. When the utility model is used, the inner of the quick cooling jet metal thin strip equipment can maintain the constant pressure and the constant flow of the liquid. The utility model is characterized in that by using a crown rod, a lever and a sensor; a float can make a measuring signal input to a double-closed loop measuring and controlling system; so the measuring signal is displayed, a lifting rod is controlled to lift or fall, and a displacement sensor and a plug rod are driven; thereby, a sprue gate can be opened or closed by the plug rod. Compared with the prior art, the liquid level automatic measuring and controlling device has the features of simple structure, high measure and control precision, convenient operation, convenient maintenance, etc.
Description
The utility model is the automatic control of liquid device that belongs to chilling casting metal strip equipment.Be applicable to the production field of non-crystaline amorphous metal.
The high capacity production equipment that is used for production wide format amorphous metal strip, key are the control to the discharge of middle Baogang liquid and nozzle bag liquid level.Because can the amorphous thin ribbon quality of production depend on the constant voltage and the constant current that guarantee solution in the nozzle bag again.As prior art, it is that nozzle bag and fusing bag are an integral body that a kind of this device basic structure of sealing pressurization chilling spray belting (clear 60-46845) has been introduced by FDAC metal Co., Ltd., through adopting this device sealing pressurization, the spray band is finished in constant voltage, the constant current of control solution.So this apparatus structure complexity, easy obstruction of nozzle mouth and alloy solution are easy to the finite capacity by the leakage of nozzle mouth place and this device, make to produce to be subjected to certain restriction.
The purpose of this utility model provides a kind of by nozzle bag measuring liquid level height, by the flow of tundish control solution, makes the constant pressure and flow of maintenance solution in the nozzle bag and automatic measurement and control device simple in structure.
The concrete structure of the utility model level gauging control device can 1 be described below with reference to the accompanying drawings: 1 float push rod in the accompanying drawings, 2 floats, 3 fulcrums, 4 Bars bars, 5 sensors, 6 lifters, 7 stopper rods, 8 sprue gates, 9 displacement transducers, 10 pairs of closed loop measurement and control systems.In the utility model device, float 2 adopts fire resistive material to make, because the proportion of fire resistive material is less than molten steel proportion, so this float always floats on the molten steel.In the nozzle bag when the molten steel liquid level rises to the height of setting value, float 2 rises with the molten steel face, by push rod 1, Bars bar 4 is delivered to sensor 5 with the displacement that float 2 rises or descends, becoming electric signal to be input to TT﹠C system 10 change transitions of displacement by sensor 5 shows and handles, by two closed loop measurement and control system 10 control lifters 6, make elevating lever again by setting requirements or liter or falling.Vertical direction has a pitman shaft in the elevating lever upper end, and an end of pitman shaft connects with stopper rod 7, and the other end and displacement transducer 9 link.When in the nozzle bag 11 during the molten steel quantity not sufficient, then float 2 descends, and by push rod 1, Bars bar 4 and sensor 5 are with the two closed loop measurement and control systems 10 of signal input.Control the elevating lever rising of lifter 6 after the display process and mention stopper rod 7 and displacement transducer 9, make that molten steel is injected in the nozzle bag 11 by sprue gate 8 in the tundish, and displacement transducer 9 highly feeds back to the rising of stopper rod 7 and shows in two closed loop measurement and control systems and the rising height of control lifter 6 elevating levers.When molten steel in the nozzle bag 11 rose to the setting liquid level, float 2 can feed back to 10 demonstrations of two closed loop measurement and control systems and the decline of control lifter 6 elevating levers by said mechanism with signal, makes stopper rod 7 close sprue gate 8, and displacement transducer 9 returns to zero-bit.When molten steel is sprayed by nozzle mouth place, wrap interior liquid level and descend thereupon, 2 of floats pass through push rod 1, and Bars bar 4 and sensor 5 input to signal 10 demonstrations of two closed loop measurement and control systems and control the rise of lifter 6 elevating levers; Mention stopper rod 7 and displacement transducer 9, make molten steel be injected in the nozzle bag 11 and reach setting value by sprue gate 8, keep the spray volume of molten steel in the nozzle bag 11 to equal injection rate IR, by what of the gap size at the lifting value decision stopper rod 7 of float 2 on the molten steel face and sprue gate 8 and tundish 12 molten steel discharges.Liquid level and constant pressure and flow in the nozzle bag 11 have been guaranteed.
It is simple that the utility model liquid level automatic measurement and control device compared with prior art has an apparatus structure, measures precise control, and the liquid level error control are in ± 5mm in the nozzle bag 11.Compare with day present technique (clear 60-46845), this device need not adopt this complex apparatus of sealing pressurization, can reach the effect of constant pressure and flow equally, and has overcome that the nozzle mouth easily stops up, molten steel leaks and shortcoming such as output is little.Simultaneously the utility model measure and control device also has characteristics such as directly perceived, the easy to maintenance and cost of processing ease is low.
