the furnace. This is typically accomplished by the use of metallic recuperators (air heat exchangers). Although recuperation has increased reheating furnace efficiencies, there is a substantial opportunity within the continuous reheat furnace population to reduce fuel consumption, even in furnaces equipped with recuperators.
Ertem et al. [13] investigated the energy efficiency of slab furnace in iron and steel production plant and came up with a result that the energy efficiency of the slab furnace was 64.26% while ...
In steel industry, reheating furnaces are the biggest energy consumers after blast furnaces. As a result, reduction of energy consumption is the major concern of furnace control.

Reheating furnace for steel rolling mill line is a device (an industrial furnace) that heats a material or a workpiece (generally a metal) to rolling forging temperature in the metallurgical industry.. Structure and composition. According to the distribution of furnace temperature, the furnace is divided into preheating section, …
Considering the furnace net capacity of m ˙ s t e e l = 160 t/h, a total electrical motor power of P e l, t o t = 0.004 GJ/t is required, which is 0.24% of the input fuel enthalpy h f u e l = 1.429 GJ/t. Therefore, the electric energy demand for the process heat generation in terms of fans will be neglected in all further calculations.
Reheat furnaces typically consume 1.2-1.6 GJ/t of steel, and oxyfuel solutions can reduce fuel and CO2 emissions by up to 50%. Linde is the world-leader in oxyfuel steel reheating; its REBOX ...
And the reheating furnace is one of the main energy consuming equipment in the iron and steel enterprises [21]. Its energy consumption accounts for 15–20% of the total energy consumption and 70% of the energy consumption of the rolling process [22], [23]. Consequently, the energy consumption of the reheating furnace is a hot issue of …
Reheating furnace for long products (billets, blooms, bars, slabs,…) usualy on head into hot rolling mills. The Walking Hearth/Beam Furnace has a system of beams, made of refractory or tubulars, which placed over a mechanical frames system and hydraulicaly powered, allows to the furnace to make the move of the products, the resulting move is …

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.
The heating process in a reheating furnace is a continuous process where the steel stock is charged at the furnace entrance, heated in the furnace and discharge at the furnace exit.
34 rowsReheat Furnace. After cooling, the slab, bloom, or billet must be reheated and "softened" for the next forming operation (such as rolling, forging, or extrusion) by raising …
ii) Rerolling Mill Furnace. a) Batch type. A box type furnace is employed for batch type rerolling mill. The furnace is basically used for heating up scrap, small ingots and billets weighing 2 to 20 kg. for rerolling. The charging and discharging of the 'material' is done manually and the final product is in the form of rods, strips etc.
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.
