Abstract
The invention discloses a protective device for an external connecting pipe of a converter and a manufacturing method of the protective device. The protective device comprises the external connecting pipe of the converter made of a high-pressure boiler pipe, a protective steel pipe is arranged on the outer side of the external connecting pipe of the converter in a surrounding mode, the protective steel pipe is a square pipe with the two ends open, an anchoring frame is arranged on the outer side of the protective pipe, the anchoring frame comprises multiple sets of claw-shaped anchoring parts which are evenly arranged, the anchoring parts are filled with refractory materials to form a heat insulation layer, each group of anchoring parts comprises a vertical anchor rod perpendicular to the protective steel pipe, the bottom end of the vertical anchor rod is fixed on the outer side of the protective steel pipe, and an inclined anchor rod is connected to each of two sides of the bottom end of the vertical anchor rod. The problem that in the prior art, the external connecting pipe of the converter is prone to pipeline burst is solved.
