Abstract

The invention discloses a device and a method for producing a small hollow electroslag ingot, belongs to the technical field of hollow electroslag ingot melting, and solves the technical problems of incapacity of ensuring the concentricity of the hollow electroslag ingot, incapacity of ensuring a high filling ratio, complex structure, high production cost and inapplicability to a small hollow electroslag ingot in the prior art. According to the device disclosed by the invention, an inner crystallizer is fixed to a bottom water tank, and an outer crystallizer is of a movable structure. The method disclosed by the invention comprises the following steps: welding a re-melting electrode of the hollow electroslag ingot; melting a solid pre-melting slag; pouring the liquid slag into the crystallizers in the invention, and carrying out electrifying melting; and carrying out die release after the melting is concluded. The device disclosed by the invention has the advantages of being simple in structure, easy to produce, simple to operate during a melting process, and low in production cost.

Description

technical field [0001] The invention belongs to the technical field of hollow electroslag ingot smelting, and particularly relates to a production device and a method for a small hollow electroslag ingot. Background technique [0002] At present, most of the domestic production of thick-walled tube blanks are produced by forging and boring of electric furnace ingots, extrusion and perforation of solid billets, and centrifugal casting. High; cast steel pipes are prone to casting defects and cannot meet high performance requirements; hollow tube blanks produced by electroslag remelting have uniform composition and structure, less gas and inclusion content in steel, and low production costs, which can replace forging and casting tube blank, so the production of hollow electroslag ingot has a lot of room for development. [0003] The production process of hollow electroslag ingot is relatively complicated, especially the structural design of the mold. If the structural design o...
