Novel zinc pipe continuous casing technology

Abstract

The invention discloses novel zinc pipe continuous casing technology which comprises a crystallizer provided with a cylinder-shaped inner die and a cylinder-shaped outer die. The inner die is provided with an inner cooling sleeve. An outer cooling sleeve is arranged below the outer die. The novel zinc pipe continuous casing technology is characterized in that zinc is dissolved into liquid zinc. The liquid zinc is transferred to an entrance of the crystallizer and enters into the crystallizer from a liquid metal entrance of the crystallizer. Inner cooling water extends into the crystallizer from the above and flows out through an inner pipe wall of a workpiece. Outer cooling water enters from an outer cooling water entrance of one side of the outer cooling sleeve and flows out along an outer pipe wall of the workpiece. A liquid metal zone, a congealing zone and a cooling zone are formed from top to bottom in the crystallizer. The inner pipe wall and the outer pipe wall of the workpiece are cooled and congealed to be formed. When the liquid zinc reaches the cooling zone, the liquid zinc completely forms. A congealed zinc pipe is continuously pulled out of the crystallizer so as to obtain a continuously cast zinc pipe. With the novel zinc pipe continuous casing technology, a zinc pipe with limitless length can be continuously cast and application range of products is wide.

Description

technical field [0001] The patent of the invention relates to the field of metal pipe casting, in particular to a new process for continuous casting of zinc pipes. Background technique [0002] In the prior art, the zinc pipe has always been cast with a certain length of mold, one section at a time. This traditional method requires more molds, slow production speed, high production cost and labor intensity. The length of the zinc pipe is fixed. The zinc pipe of the required length cannot be flexibly cut according to the needs, and it can only be achieved by welding when a longer zinc pipe is needed. Contents of the invention [0003] The invention aims at the problems existing in the prior art, and provides a new zinc pipe continuous casting process with high production efficiency. [0004] The new zinc pipe continuous casting process of the present invention includes a crystallizer, the crystallizer has a cylindrical inner mold and an outer mold, an inner cooling jacket ...
