Embodiment Construction

[0023] Aluminum alloy crystallizer for electroslag melting casting small guide vanes, including inner cavity plate 4, outer cavity plate 6, reinforcement rib 7, tie rib 8, upper flange 1 and lower flange 10, water inlet pipe 9 and water outlet pipe 5 , Additional steel plate 3.

[0024] The inner cavity type plate, reinforcing rib, upper flange, and lower flange are cast into an integral structure by casting method; the outer cavity type plate, tie bars, and water inlet and outlet pipes are formed into an integral structure by cold bending welding or casting method. The mold body is formed after the inner cavity mold plate (including reinforcing ribs, upper flange and lower flange) is integrally welded with the outer cavity mold plate (including tie bars and water pipes). The additional steel plate 3 is fixedly connected with the upper flange 1 through bolts 2 . Among them: the thickness of the inner cavity plate is 10-15mm, the thickness of the reinforcing rib is 10-15mm, th...

Abstract

The aluminum alloy crystallizer for electroslag fusion casting of small guide blade includes inner cavity plate, outer cavity plate, reinforcing ribs, bracings, upper flange, lower flange, water inlet pipe and water outlet pipe. The inner cavity plate, the outer cavity plate, the reinforcing ribs, the upper flange and the lower flange are cast into one integral structure; the outer cavity plate, the bracings, the water inlet pipe and the water outlet pipe are cast or welded into one integral structure; and the inner cavity plate, the reinforcing ribs, the upper flange, the lower flange, the outer cavity plate and the bracings are welded integrally. The present invention adopts aluminum alloy material with performance between copper and steel, and has the advantages of good casting performance, good welding performance, low cost, etc.

Description

technical field [0001] The invention relates to a mold for casting, in particular to an aluminum alloy crystallizer for electroslag melting guide vane and its preparation and use method. Background technique [0002] Electroslag casting is a special casting method integrating metal refining and casting molding. Electroslag casting can produce high-quality castings with dense structure, high dimensional accuracy and less non-metallic inclusions. [0003] The crystallizer is an important part of the electroslag furnace. On the one hand, it acts as a melting chamber for melting and refining; on the other hand, it plays the role of casting molds to form castings. [0004] The crystallizer for electroslag casting (equivalent to the sand mold of ordinary casting) usually adopts steel or copper-steel structure, but there are different degrees of shortcomings. The thermal conductivity of the steel in the steel crystallizer is small, resulting in poor molding quality of the casting;...
