One part of the production process consists of reheating the steel slabs in a slab reheating furnace to a pre-defined temperature, usually between 1200 °C and 1300 °C. After this heating, steel strips are formed by rolling the slabs. The first mill the steel slab goes through is the roughing mill.
3 Reheating furnaces for hot rolling mills These types of reheating furnaces are traditionally lined with hard (dense) refractory such as bricks, castable, gunite, shotcrete, etc. Such dense refractory do not fare well when exposed to intense and continuous flame impingement, thermal cycling and ...
A reheating furnace is not only a crucial apparatus but also a principal source of power consumption in a tandem hot-rolling steel mill [1]. Regenerative pusher-type reheating furnaces and compact strip production (CSP) soaking furnaces are common reheating furnaces for hot-rolled production lines of billets.
Typically, a reheat furnace in a hot rolling mill for . steel has to raise the metal . temperature from ambient . to around 1200 oC (2192 oF). ... For example, when reheating billets, the steel may be heated correctly, but it could . …
Reheating furnaces in integrated and mini-mills consume approximately half of the natural gas used to produce hot-rolled products. Recently, Praxair's Dilute Oxygen Combustion technology (previously demonstrated for productivity improvements on mini-mill billet reheating furnaces) was extended to a slab reheating furnace.
