Continuous casting and rolling device for steel and nonferrous metal

Abstract

The invention belongs to the technical field of casting and rolling equipment, and particularly relates to a continuous casting and rolling device for steel and nonferrous metals. The continuous casting and rolling device comprises a casting and rolling roller system composed of working rollers and a plurality of sets of supporting rollers, the working rollers and at least one set of the supporting rollers adopt an internal closed water cooling structure, a casting and rolling roller system positioning device is arranged inside a memorial archway frame, and meanwhile a pressing power device connected with the casting and rolling roller system is arranged. Micro-motion adjusting devices are arranged between the upper and lower working rollers and a balance roller system, a feeding device isarranged at the feeding end between the upper working roller and the lower working roller of the continuous casting and rolling device, a plate type detection device is arranged at the discharging end, and a high-precision cooling system is arranged at the rear end of the plate type detection device. According to the continuous casting and rolling device for steel and nonferrous metal, rapid cooling in the casting and rolling process is realized through equipment innovation, the size and plate type precision of steel and nonferrous metal plates and strips in the casting and rolling productionprocess is improved, and steel and nonferrous metal plate and strip finished products are directly cast and rolled.

Description

technical field [0001] The invention belongs to the technical field of casting and rolling equipment; in particular, it relates to a continuous casting and rolling device for steel and nonferrous metals. Background technique [0002] Currently known metal strip (billet) production methods mostly adopt ingot hot-rolling method and cast-rolling method: the ingot hot-rolling method includes: batching and smelting-semi-continuous casting "slab"-(milling - sawing) - heating - hot rolling - cold rolling / foil rolling - annealing - packaging process; casting and rolling process includes: batching and smelting - continuous casting "slab" - cold rolling / foil rolling - annealing - packaging process; The ingot hot rolling method is currently the most widely used metal strip (billet) production method. The casting and rolling method is a green short-process strip (billet) production technology, which can be directly cast and rolled to a thickness of 1mm to 10mm. The slab or cast slab, t...
