Continuous casting billet hot delivery and offline system

Abstract

The invention discloses a continuous casting billet hot delivery and offline system comprising a continuous casting machine discharging roller (1), a steel casting machine (2), a hot delivery roller (3), a warming roller (4), a casting blank insulation bed (7) and a hot delivery rolled steel roller (10). The steel casting machine (2) can transport casting blanks on the continuous casting machine blanking roller (1) to the hot delivery roller (3) or to the warming roller (4); the warming roller (4) deliveries the casting blanks to the casting blank insulation bed (7), and the casting blanks onthe casting blank insulation bed (7) can be transported to the hot delivery roller (3), and the hot delivery roller (3) transfers the casting blanks to the hot delivery rolled steel roller (10). The continuous casting billet hot-feeding and the offline system can control the surface temperature of the casting blanks between 550 DEC C to 650 DEG C, thereby meeting the requirements of the steel rolling process; in addition, the casting blanks can be temporarily stored in case of the roller change and the small fault on the rolling steel production line. The continuous casting billet hot deliveryand offline system has the functions of improving the casting blank hot delivery and reducing the casting blank offline directly.

Description

technical field [0001] The invention relates to the technical field of continuous casting in iron and steel production, in particular to a continuous casting billet hot delivery and off-line system. Background technique [0002] With the development of the iron and steel industry, iron and steel enterprises pay more and more attention to energy saving and consumption reduction. Among them, the continuous casting slab hot delivery and hot charging process is a major measure for iron and steel enterprises to save energy and reduce consumption, improve production and quality. Its realization is based on supporting equipment and the premise of obtaining high-temperature and defect-free slabs. It is a comprehensive technology that integrates a series of technologies such as production planning, continuous casting production, slab transportation, heating and rolling, and scheduling management. Especially in the matching and forward movement of continuous casting and steel rolling ...

AI Technical Summary

Problems solved by technology

Due to the difference in the production rhythm and maintenance interval between steel rolling and continuous casting machines, if the rolling rolls are changed, the continuous casting slabs usually need to go off the production line directly, which reduces the heat delivery rate; The requirements for hot delivery temperature are different. For example, some steel grades require a hot delivery temperature greater than 700°C, while others require a hot delivery temperature of 550°C-600°C. Conventional continuous casting hot delivery systems cannot meet the requirements.
