Argon distribution apparatus of plate blank continuous casting machine ine

The utility model provides an argon distribution apparatus of a plate blank continuous casting machine, which comprises an argon input main pipe and an argon output branch pipe, wherein the argon input main pipe is provided with a control valve and a filter; the argon output branch pipe is provided with a control valve. The utility model is characterized in that two output branch pipes outputting argon to a water inlet and a lower sliding plate are connected in parallel with the argon input main pipe; each of the argon output branch pipes is provided with a flow meter, a pressure reducing valve and a flow regulating valve. The proposal controls argon conveying branch pipes of the upper water inlet and the lower sliding plate separately, can regulate the argon flow quantity of the upper water inlet in time to an optimum level, but simultaneously does not influence the argon flow quantity of the lower sliding plate and reduces the water inlet sealing probability of the upper water inlet. In addition, the utility model has the characteristics of simple structure, low cost and high reliability, plays an important role in the smooth running of various kinds of steel casting, and can improve continuous casting rate, promote casting blank quality, reduce middle off-cut steel and raise metal yield.
