In the hot rolling mill, a cold slab is reheated in reheating furnace and then rolled into thin coils through hot rolling process. Traditional research on hot rolling mill generally takes the two processes as two separate single-objective scheduling problems, though they are closely connected and their optimization objectives are conflicting with each other.
Efficient reheating and ingot handling. Our aluminum-ingot reheating furnaces are available in direct gas-fired or electrically heated pusher-type versions. Whichever design you choose, your furnace effectively reheats continuous or semi-continuous ingots before hot rolling. You can also use it to homogenize ingots at higher temperatures.

Reheating Furnace is the heart of any hot rolling mill where in the charge is heated to rolling temperature.The charge could be in the form of billets, blooms, slabs or ingots.The type of furnace could be pusher, walking hearth or walking beam – either top fired or top and bottom fired.The fuel used could be either oil or gas.
Heating Furnace What You Need to Know. 1. Heating furnace's purpose. The heating furnace is to heat the billet to a uniform temperature (austenite structure) suitable for rolling. After the temperature increases, the first thing is to improve the plasticity of the steel and reduce the deformation resistance, so that the steel is easy to deform.

Fig 2 Typical arc-tangent curve used for heating steel in a reheating furnace. Factors affecting heating efficiency. Factors which contributes to low heat efficiency of the reheating furnace include (i) the capacity of the furnace not matched with the rolling mill capacity, (ii) inappropriate equipment used for the combustion, (iii) non provision of …
The rolling process begins by continuous casting 7, or if an older, not modernized steel plant is considered, by ingot casting.In the most modern mills continuous casting is followed directly by hot rolling. In all of these cases the pre-rolling structure consists of dendrites which are subsequently removed in the reheat furnaces in which most of the alloying elements enter …
Rebar Rolling Mill Line Manucturer Of Rolling Mill. Apr 28, 2020 Disadvantage of normal type reheating furnace . For normal reheating furnace, the smoke discharging temperature to chimney is around 250-300degree, in this process, it take away some heat from the furnace inside, and the burning mouth inside is not on pair, so the temperature evenly is not as good …
Reheating Furnace.

Reheating furnace is an essential facility of a rod mill plant where a billet is heated to the required rolling temperature so that it can be milled to produce wire. Although it is very important to obtain information on billet temperatures, it is not feasible during furnace operation. Consequently, a billet temperature profile should be estimated.
