Abstract
The invention discloses a rolling technology arrangement of a zirconium plate and zirconium strip cold-milling unit and further discloses a rolling method of the zirconium plate and zirconium strip cold-milling unit. According to the rolling technology arrangement, a rolling mill is included. A turning roller C, a turning roller B, a turning roller A and an uncoiler are sequentially arranged on one side of the rolling mill; a straightening machine is arranged between the turning roller A and the turning roller B, and a solid core coiling machine A is arranged between the turning roller B and the turning roller C; a turning roller D, a turning roller E, a turning roller F and a coil-discharging coiling machine are sequentially arranged on the other side of the rolling machine; and a solid core coiling machine B is arranged between the turning roller D and the turning roller E, and a hydraulic shear A is arranged between the turning roller E and the turning roller F. The conditions of low rolling and calendaring yield rate, complicated operation, high energy consumption and low-efficiency zirconium plate and zirconium strip rolling and calendaring are improved, the production rhythmis accelerated by a large margin, the equipment utilization rate is increased by a large margin, and the zirconium yielding rate is increased by a large margin.
Description
technical field [0001] The invention belongs to the technical field of calendering and rolling of non-ferrous metals, and relates to a rolling process arrangement of a zirconium plate and a strip cold rolling unit, and also relates to a rolling method of the above cold rolling unit. Background technique [0002] The melting point of zirconium material is as high as 1852°C, and it has ultra-high hardness and strength. It has a tendency to rebound when deformed, and it is prone to cracks caused by nicks. At the same time, zirconium material has a tendency to bite. Zirconium material is an internationally sensitive strategic material and is a controlled material. Zirconium production line is the material basis for the development of nuclear energy. The "sponge zirconium" extracted through a complex smelting process is then melted and pressed into small pieces of zirconium plate blanks, and then rolled into various products through appropriate pressure processing methods, which...
