Hot air main pipe refractory masonry mold and its construction method

Abstract

The invention relates to a hot blast main refractory material building die and a construction method thereof. The die comprises a center shaft and three supporting rods with the middle portions rotationally arranged on the center shaft. The supporting rods can stretch and contract on the two sides of the center shaft. Arc arms are hinged to the two ends of each supporting rod, one ends are provided with butt-joint clamping grooves, the arc arms are distributed around the center shaft in the same direction and are equal in length, the other ends of the arc arms can be connected with the butt-joint clamping grooves in the next supporting rods in a matched manner, and the refractory brick inner circle meeting the design requirement can be defined after the arc arms and the butt-joint clampinggrooves are connected in a matched manner. According to the die, construction is conducted in a rotation pushing manner, the number of pipe interior supports is reduced on the premise that the quality testing and die dismounting time is saved, the quality is guaranteed on the premise that space is saved, the construction quality problem can be rapidly found, repeated usage can be achieved in thenarrow space of a hot blast main, and collisions are avoided.

Description

technical field [0001] The invention belongs to the field of metallurgical construction, and in particular relates to a refractory masonry mold for a hot blast main pipe and a construction method thereof. Background technique [0002] During the refractory masonry process of the hot air main pipe, the existing mold is generally pushed forward along the axis, and the construction of the mold in the pipe is affected by the poor adjustment during the plane restriction and large turnover process. Not only the construction accuracy error is large, but also it is easy to cause secondary damage in the pipe Collision, the long time of masonry in the pipe has caused problems such as low construction efficiency and excessively large masonry mortar joints. Contents of the invention [0003] The object of the present invention is to provide a refractory masonry mold for hot blast main pipe and its construction method. The mold is constructed in a rotating and propelling manner, reduci...
