Automatic control technology complete set of plant of tap hole gate valve steel slag-blocking system

A complete set of apparatus of a steel-tapping hole gate-valve slag-blocked system automation control technology relates to a liquid steel slag-blocked apparatus of a steel-making revolving furnace, which comprises a gate-valve slag-blocked apparatus, a water-cooled cylinder, a five-channel rigid rotary connection apparatus, wherein the gate-valve apparatus is a translational valve, a sliding door starts and stops a fireproof spool through pulling, the water-cooled cylinder is a hydraulic cylinder and is put in a cold water tank, and simultaneously, the oil way of the five-channel rigid rotary connection apparatus is arranged in cold water. The function of a slag roughing detecting apparatus comprises doing image treatment to signals input by a far-infrared thermal detector and working out energy ratio of the real-time area by a CPU, then comparing with a set value, and controlling the opening of the gate-value by the comparing result. The complete set of apparatus has the advantages that the translational va
