Promptly the rise schematic flow sheet of control method of the casting chute that Fig. 1 provides for the embodiment of the present application.
As shown in Figure 1, this method may further comprise the steps:
S100: after casting is finished, detect chute and whether move.
In normal casting process, after casting is finished, will cast the chute rising usually and to the hot junction inclination, make remaining aluminium water outflow in the chute, but be in ground, the hot junction lower cover because the centre in chute hot junction is spacing, may have aluminium water or aluminium slag and fall in the cover plate and block spacing.Therefore after casting is finished, need at first detect chute and whether move, if the chute motion is so just operated according to normal flow process, if chute does not move, so just need handle according to the application's subsequent step.
When whether the detection chute moves, can adopt on the chute next door limit switch is set, also can be provided with displacement transducer by chute.Because slightly rocking may appear after casting is finished in the reasons in structure of chute, if adopt this moment the fiber switch just the erroneous judgement problem may occur, namely chute touches the fiber switch and not motion.So in the embodiment of the present application, preferably adopt displacement transducer to detect the motion conditions of chute.
S200: when chute does not move, generate washout the casting machine power supply is disconnected.
In previous step, when detecting chute and do not move, spacing may being blocked by aluminium water or aluminium slag on the chute is described, need disconnect the working power of casting machine this moment, to avoid the unexpected misoperation of chute.Here the working power of casting machine is to point to the power supply that each working position of casting machine provides 230V voltage, in addition, also have some to be used for to the 24V dc source of part control position power supply at casting machine, when the 230V working power with casting machine disconnects, these 24V dc sources still continue power supply, for controlling the part of casting machine after outage.
S300: generate first control signal and send to urgent rising threshold, urgent rising threshold control chute is risen.
When generating washout, need the control chute to rise, this is because if chute can not normally rise, and will cause aluminium water not release out, finally may cause aluminium water to emit groove to spill and scorches equipment and instrument.
In the embodiment of the present application, when chute did not move, the control chute rose by urgent rising threshold, and chute will not be subjected to middle spacing control this moment, so can avoid owing to the middle spacing problem that is stuck and occurs.
