Underdrive-concentrated withdrawal and straightening machine with thermal insulation device

Abstract

The invention provides an underdrive-concentrated withdrawal and straightening machine with a thermal insulation device, which comprises a driving device and is characterized in that a first driving roller, a second driving roller and a third driving roller are arranged on a withdrawal and straightening machine base lined with refractory castables, a first driven roller and a second driven roller are respectively arranged above the first driving roller and the third driving roller and are driven to do lifting movement in a lifting guide cover device to ensure that the first driving roller together with the first driven roller and the third driving roller together with the second driven roller to clamp and deliver steel billets to move and to be straightened. The invention has the advantages of realizing and improving the working conditions and the surrounding environment of the withdrawal and straightening machine, reducing water energy consumption, preventing excessive heat dissipation and realizing high degree of sealing in the whole process of heat transferring in order to achieve the purposes of decreasing the heat dissipation of a hot billet, improving charging temperature, reducing energy consumption and steel consumption and improving product quality and provide conditions for the hot charging and hot conveying of some steel types in a protective atmosphere and the direct rolling of the steel billet.

Description

technical field [0001] The invention relates to a centralized lower-transmission progressive tension leveler with a heat preservation device, which is used in continuous steel casting, hot billet hot delivery and hot charging, and energy-saving devices in iron and steel plants. Background technique [0002] Iron and steel enterprises are large energy consumers with great energy saving potential, and they are also large pollutant dischargers, so there is a long way to go to reduce emissions. High quality, energy saving, consumption reduction, and benefit are the goals that enterprises have always pursued. Energy saving and emission reduction are twin brothers. This serious natural disaster has been promoted to a major event related to human survival. Hot delivery and hot charging of steel billets in iron and steel plants have become very common, and have achieved good energy-saving effects, and there is still a lot of potential to be tapped. At present, the hot billet is ge...

However, gear transmission can also be used, and open cantilever gears or distribution gearboxes are used to place the transmission equipment outside the production line (only for the outside of the production line). The production of gear transmission is more reliable, but it occupies a larger area.
