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.

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 recuperators or
2021-8-19 The furnace in rolling mill is a device that heats the material or workpiece. According to the heat source, there are fuel heating furnace, resistance heating furnace, induction heating furnace, microwave heating furnace, and so on.Applications include petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics,
2020-11-1 Reheating furnaces are widely used in the Iron and Steel Industry to reheat the semi-finished products like slabs or billets to the rolling temperature at 1250 °C. Reheating furnace is one of the major energy consuming equipment for rolling mills. It is also important to optimize the fuel consumption in this reheating process to avoid any
Have you ever thought about heavy-duty, no-frills furnaces for billet reheating? Then a pusher furnace is a smart choice. Why? Because this type is designed specifically to operate in low-production-rate mills for common steel grades such as rebars. Highly adaptable . Top-fired pusher-type furnaces combine the benefits of sturdy construction
the Pipe Mill is staged toward the east end of the mill bay until it is cool enough to load onto rail cars. Reheating Critical to the Hot Strip Mill is its walking-beam reheat furnace, state-of-the art equipment that replaced and now outperforms three older- (pusher-) style furnaces. Nominally rated to produce 270 tons-per-hour,
Hot Rolled Production. The first step of shaping semi finished product (a square billet in our case) to its initial form is called hot rolled production. The billet is usually produced by either blast furnace or electric arc furnace method. Depending on the size and the length of finished product, the square billet is first cut to calculated
