The Rolling Mill Twin Channel is utilized to gather the TMT bars leaving the Extinguishing boxes subsequent to being sheared by the Flying Shear in two strands. These channel includes CI focal box, water cooled to counteract distorting amid rolling, and C-type CI channels which are suspended from a longitudinal basic.
The reheating furnace and roughing mill of a hot strip mill were studied. A novel control method using measurement data gathered from the production line is proposed.
2). The furnace production rate can reach 170 t/h. The furnace is divided as follows: zone 1 allows billets preheating process, zone 2 and zone 3 perform the billets reheating process while the soaking action takes place in zone 4 and zone 5 (disposed one close the other, perpendicularly with respect to the furnace axis). The billets furnace ...
NEDO reports that using regenerative burners on a 110 t/h capacity billet reheating furnace (operating at 1050 o C) can reduce the energy consumption by 0.18 to 0.21 GJ/t-steel, as compared a conventional furnace. Annual energy savings are reported to be 9.3 to 11.6 GWh ((NEDO, 2008. p. 88)
