The specific embodiment
The present invention is directed to aluminium and aluminum alloy semi-continuous casting process, improve lubricating oil pressure by logic circuit control gas-liquid power-increasing cylinder, according to casting speed and ingot casting specification, control gas-liquid power-increasing cylinder pressure and relay on-off frequency, thereby pressure and the lubricating oil outlet flow and the pulse oil supply number of times of control lubricating oil, make lubricating oil see through graphite cannula and form oil film, play the effect of continuous lubrication at the graphite cannula inwall.
The present invention is described in further detail below in conjunction with Figure of description:
As Fig. 1, the continuous lubricating system of a kind of aluminium of the present invention and aluminum alloy semi-continuous casting comprises compressed air supply unit 1, source of the gas processing unit 2, magnetic valve 3, gas-liquid power-increasing cylinder 4, repairing mouth 5, oil pressure gauge 6, oil pressure shut-off switch 7, electro-hydraulic reversing valve 8, choke valve 9 and logic circuit.
Compressed air supply unit 1 provides compressed air, after the compressed air feeding system, at first carrying out contaminant filter by 2 pairs of compressed air of source of the gas processing unit separates with moisture, and regulate compressed-air actuated pressure to 0.8～1.6MPa, compressed air after the processing is by magnetic valve 3 (two-position-five-way solenoid valves, model: MFH-5-1/4-B) enter gas-liquid power-increasing cylinder 4, lubricating oil enters in the gas-liquid power-increasing cylinder 4 through repairing mouth 5, the piston that compressed air promotes gas-liquid power-increasing cylinder 4 moves, by changing the lifting surface area of piston, increase the pressure of lubricating oil in the gas-liquid power-increasing cylinder 4, magnetic valve 3 is under the control of logic circuit, the work of control gas-liquid power-increasing cylinder 4, when the lubricating oil pressure in the gas-liquid power-increasing cylinder 4 reaches the operating pressure of 7～15MPa, oil pressure shut-off switch 7 is by logic circuit control magnetic valve 3, stop the work of gas-liquid power-increasing cylinder 4, and unlatching electro-hydraulic reversing valve 8 provides extreme pressure lubricant through choke valve 9 to graphite cannula 10 outer walls, when lubricating oil pressure is lower than the operating pressure of 7～15MPa, oil pressure shut-off switch 7 is closed electro-hydraulic reversing valve 8 by logic circuit, stop to provide lubricating oil to graphite cannula 10 outer walls, by control magnetic valve 3 gas-liquid power-increasing cylinder 4 is started working, improve the pressure of lubricating oil, make the pressure of lubricating oil satisfy job requirement.Because lubricating oil is pulsed output, therefore, when lubricating oil pressure descends, logic circuit is closed electro-hydraulic reversing valve 8, makes gas-liquid power-increasing cylinder 4 work by control magnetic valve 3, improves the pressure of lubricating oil in good time, reach job requirement, do not influence the normal supply of lubricating oil; According to casting speed and ingot casting specification regulating impulse oil supply number of times and each oil mass of giving.
