Liquid level control system for conticaster mould

The present invention discloses a liquid-level control system for crystallizer of conticaster. Said invented system includes crystallizer, support, liquid-level sensor, driver, controller, digital electric cylinder, stopper mechanism, press bar and hand-held controller. The above-mentioned devices are formed into a closed loop system by using digital signal and by means of control system to traceand control the change of liquid level accurately at all times. Said invented system adopts digital control technique, has no hydraulic and clutch mechanism, so that it is simple and reliable in structure, rapid in response rate, high in control accuracy, low in cost and energy consumption and safe in use.

Full automatic fuzzy control dust-removing system for blast furnace

Full automatic dusting system with fuzzy control

A full-automatic dusting system with fuzzy control is composed of blower, dusting accessories, industrial control computer, and variable-frequency speed regulator to form a close-loop control system which can automatically track and set up desired values based on fuzzy control theory. The smoke dust concentration of blast furnace during tapping-off can be automatically tracked and the wine amountis controlled based on tracked result. On smelting, the system does not work, so saving electric power and elongating service life. Said system has high dusting effect.
