Abstract

The invention discloses a construction method for an air curtain retaining wall of a dry material tundish. Firstly, the steel mold for air curtain wall with inlay groove and the steel mold for argon blowing pipe with inlay groove are made. The materials inlaid in the two molds are thin foam; the thin foam is inlaid in the two steel molds respectively On the side, place the two molds inlaid with thin foam boards at the designed positions, and align the center points of the tops of the two molds; then install the flow stabilizer, lay the bottom, and lower the tire membrane, and then pour the cladding material to vibrate. Baking; then take off the tire film, and then remove the two molds; remove the mold after removal, then pave and install the air curtain wall; The surroundings of the curtain wall are streamlined, and finally the surface of the air curtain wall is cleaned to complete the installation; finally, it is naturally dried, baked on the line, and used after baking. The construction method of the invention greatly reduces the labor intensity of workers and improves construction efficiency.

Description

1. Technical field: [0001] The invention relates to a construction method, in particular to a construction method of an air curtain retaining wall in a dry material tundish. 2. Background technology: [0002] The tundish is the last container in the steelmaking process, and tundish metallurgy is also an important link in the steelmaking process, which has a great impact on the cleanliness of molten steel. The tundish air curtain retaining wall has the function of prolonging the residence time of molten steel, promoting the floating of inclusions, and increasing the chance of collision and growth of inclusions to promote floating. At the same time, it also has the function of a vacuum pump and can remove nitrogen, hydrogen, and oxygen in molten steel. Therefore, the application of the air curtain retaining wall in the tundish plays an important role in clean steel. According to the different construction methods of the tundish, the tundish can be divided into a smear package...
