Round billet continuous casting machine with especially big sectional plane

Abstract

The invention discloses a super large cross section (phi 800 to phi1,000mm of diameter) round billet continuous caster, which is characterized in that the continuous caster consists of a crystallizer provided with a foot roll, a crystallizer vibration device, an ingot supporting and guiding device, an ejection device, a protection and insulation section, and a crystallizer electromagnetic stirring device, wherein a copper pipe of the crystallizer with the foot roll is contacted with molten steel, the outer layer of the crystallizer with the foot roll is a stainless steel water jacket, the furthest layer of the crystallizer with the foot roll is a carbon steel shell, the stainless steel water jacket and the carbon steel shell are connected by an upper flange and a lower flange, and a crystallizer water tank adopts the one-inlet two-outlet one-cold circulation mode; and the crystallizer vibration device does not adopt the sine electric drive mode. The continuous caster has the advantages of novel structure, compact and reasonable arrangement, better quality and lower cost of billet, and so on.

Description

technical field [0001] The invention relates to a round billet / tube billet continuous casting device in the technical field of continuous casting in the metallurgical industry, in particular to a round billet / tube billet continuous casting device with a diameter of 800-1000 mm. Background technique [0002] The continuous casting machine is the main equipment of the continuous casting process in the modern metallurgical industry. Its structural characteristics and working principle not only determine the working efficiency and production cost of the continuous casting machine, but also directly affect the product quality. So far, there are mainly three types of billet / round billet continuous casting machines: vertical, horizontal, and full-arc, and they are widely used in industrial production practices. Their products are used in petroleum, chemical, machinery and other industries, but in Before the continuous casting machine is put into production, even in the world, wheth...

AI Technical Summary

Problems solved by technology

[0003] As the country's economic development continues to be optimistic about the market for large seamless steel pipes, the demand for billets with extra large cross-sections is increasing day by day. Before that, large ingots were mostly used as billets, and their output, quality, and yield were not satisfactory. For this reason, we have been We are exploring the use of continuous casting slabs with extra large cross-sections instead, and developing a process and equipment for a continuous casting machine with a diameter of 800-1000mm is a difficult problem that needs to be solved.
