Production method of horizontal centrifugal rotary continuous casting metal billet and hollow continuous casting billet

Abstract

The invention discloses a production method of a horizontal centrifugal rotary continuous casting metal billet and a hollow continuous casting billet. A crystallizer adapter is adopted to replace a horizontal continuous casting separation ring and is tightly connected with a crystallizer, and a horizontal continuous casting technology is adopted to be matched with a subsequent rotary throwing machine; the whole casting billet is compact in structure without defects and low in component segregation in the crystallization process through the centrifugal force generated by rotation of the casting billet, so that a continuous casting metal billet with the quality higher than that of an arc-shaped continuous casting machine is produced, and continuous production of the hollow annular casting billet is finally realized through structural change of the crystallizer adapter on the basis of realizing solid continuous casting; and water-free cooling is adopted, low-temperature gas is adopted for replacing original water spraying cooling, heat energy replacement and recovery are carried out, the annular hollow casting billet thoroughly eliminates the punching procedure of seamless pipe production, the production cost is greatly reduced, an arc-shaped section is omitted, straightening cracks of the casting billet are thoroughly eradicated, and the pulling speed and the production efficiency are greatly improved.

Description

Technical field [0001] The present invention relates to the field of mechanical techniques, and more particularly to a method of producing a horizontal centrifugal rotation coated metal blank and a hollow coil. Background technique [0002] At present, when the metallurgical industry is produced by the round-billet, there is generally used curved coil or straight arc-shaped casting production technology, and the horizontal continuous casting is less and less. The reason is that the crystallizer separation ring has always been an insurmountable barrier, and production The quality of the slabs cannot meet the actual quality requirements. The seamless tube rolling is the use of a solid round tube through the perforation of the next rolling step, while the perforation process is not only greatly limited to the production efficiency of seamless tubes, and accounts for the cost of the entire rolling production process. More than 40%. Therefore, there is an urgent need to design a metho...

Problems solved by technology

[0002] At present, the metallurgical industry generally adopts arc continuous casting machine or straight arc continuous casting production technology when producing square and round billets, and horizontal continuous casting is less and less. The billet quality cannot meet the actual quality requirements

The seamless tube rolling is to use the key process of piercing the solid round tube blank before entering the next rolling process. The piercing process not only greatly limits the production efficiency of the seamless tube, but also accounts for 10% of the cost of the entire rolling production process. more than 40%

Therefore, there is an urgent need to design a production method for horizontal centrifugal rotary continuous casting metal slabs and hollow continuous casting slabs, so as to solve the problems of easy damage of the mold separation ring and high cost and low efficiency of the piercing process in the existing horizontal continuous casting
