Plate blank movable turn-over device

Abstract

The invention discloses a slab mobile overturn device which comprises a horizontal traveling car arranged on the flank of a slab roller-way and positioned at the lower part of a slab heating furnace, wherein, a horizontal oil cylinder is connected with one end of the horizontal traveling car, an overturn oil cylinder is hinged on the rear car body of the horizontal traveling car far from the slab roller-way through a fixed support of the overturn oil cylinder, an overturn arm is hinged on the front car body of the horizontal traveling car near the slab roller-way through a fixed support of the overturn arm, a short rocker arm at one end of the overturn arm is connected with the overturn oil cylinder, the long rocker arm at the other end of the overturn arm is provided with a hook capable of supporting a slab, and a slab arresting device is arranged on the furnace frame of the slab heating furnace, restricting the slab to excessively overturn. The slab mobile overturn device effectively resolves the difficult problems that the high temperature and over loading slab with big size realizes continuous shifting out, overturn and side standing operations during the rolling process and the heat-treating process, significantly improves the slab production efficiency, and meets the demands of the oriented silicon steel manufacturing technique, in particular the demands of the HIB hot-rolled steel manufacturing technique.

Description

technical field [0001] The invention relates to a device for transporting high-temperature hot-rolled slabs in the metallurgical industry, in particular to a slab moving and turning device. Background technique [0002] In the metallurgical industry, traditional slab heating is usually carried out side by side in large walk-in heating furnaces, and the furnace temperature is difficult to reach 1400°C. Even if the furnace temperature reaches 1400°C, since the heated slab is in an unsealed environment, the slab is severely oxidized and burned during high-temperature heating, the yield of finished products is very low, and the temperature uniformity is poor. Shutdown for repairs, frequent slag removal, and short service life. [0003] With the development of high-tech in the iron and steel industry, high-temperature oriented silicon steel has been developed. In the production process of high-temperature oriented silicon steel, the slab needs to be heated evenly at a temperatu...

Problems solved by technology

At present, there is no such special transfer equipment in domestic steel rolling mills, and the related technology of this special mobile equipment is also blocked and kept secret by foreign counterparts, but this is the key equipment to solve the hot rolling process of oriented silicon steel plate and realize the uniformity of high temperature heating of the slab. It is a difficult problem to further improve the production quality of domestic high-quality grain-oriented silicon steel sheets
