Crystallizer device for continuously casting hollow tube blanks

Abstract

The invention discloses a crystallizer device for continuously casting hollow tube blanks. The crystallizer device for continuously casting the hollow tube blank comprises an inner copper tube assembly and an outer copper tube assembly which are connected integrally through a connecting beam, wherein the inner copper tube assembly comprises a water seam formed between an inner copper tube and an inner frame; the outer copper tube assembly comprises a water seam formed between the outer copper tube and the outer frame; cooling water inlet and outlet of the outer copper tube which are communicated with a vibration device are arranged at the left end and the right end of the outer copper tube; and cooling water inlet and outlet of the inner copper tube which are communicated with the vibration device are arranged at the left end and the right end of the outer copper tube. As continuous casting of the hollow tube blanks is realized through the inner copper tube assembly and the outer copper tube assembly, the crystallizer device for continuously casting the hollow tube blanks, disclosed by the invention, has the advantages of reducing production cost and saving resource. The continuous casting method has certain promotional value.

Description

technical field [0001] The invention relates to the continuous casting technology of hollow tube blanks in the field of metallurgy, in particular to a crystallizer device for continuously casting hollow tube blanks. Background technique [0002] The production methods of traditional tube blanks include die casting solid and hollow tube blanks, continuous casting square billets and round billets solid tube blanks, centrifugal casting tubes and tube blanks. Rolling seamless steel pipes with solid billets requires heating and piercing the solid billets. The production process is complicated, the production cost is high, and resources are wasted. The production methods of die casting hollow billets and centrifugal casting billets cannot continuously produce hollow billets. Its production cost is high, wastes energy, and output is low. [0003] Traditional continuous casting machine molds include slab molds, billet molds, round billet molds, special-shaped billet molds, etc., wh...

Problems solved by technology

Rolling seamless steel pipes with solid billets requires heating and piercing the solid billets. The production process is complicated, the production cost is high, and resources are wasted. The production methods of die casting hollow billets and centrifugal casting billets cannot continuously produce hollow billets. Its production cost is high, energy is wasted, and output is low

[0003] Traditional continuous casting machine molds include slab molds, billet molds, round billet molds, special-shaped billet molds, etc., which are used to produce slabs, square billets, round billets and special-shaped billets. Traditional molds can only produce solid billets. tubes, neither of which can continuously produce hollow tube blanks
