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). 04Temperature measurements in metal reheat furnaces application note. Typically, thermocouples were installed through the furnace roof or walls to measure the furnace temperature in each zone.
The amount of fuel burned in a reheat furnace means that efficiency improvements give large benefits. A gas-fired furnace typically consumes 25 m3 of fuel per metric ton of steel processed. Efficiency improvements can reduce fuel consumption by up to 10%, saving money and reducing emissions. For a large furnace, the savings can …
RKIE is specially design a coal pulverizer machine for the billet reheating furnace of steel plant from 1.5 Ton/hr. Production to 100 Ton/hr. Production in steel industries of billet size of 100x100 section to slab reheating.
objectives to furnace control, such as ensuring internal furnace temperatures do not exceed safe levels or shorten the life of the furnace and burners, in addition to the prevention of melting on the slab surface.

Our Reheating Furnaces Ensure: 1. Consistent thermal level and thermal homogeneity. Reheating Furnaces from The Steefo Group takes billets to the correct thermal level. It guarantees good thermal homogeneity as we understand that the quality of the rolling process of the finished product depends precisely on this aspect. 2. Elimination of Marks.
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 discharged at the furnace exit. Heat is transferred to the steel stock during its traverse through the furnace mainly by means of convection and radiation from burner gases and furnace walls.
Reheating Furnaces serve the purpose of heating steel blooms, billets or slabs in steel rolling mills. Reheating furnaces takes this steel stock up to approximately 1200 degree Celsius. The steel begins to deform at this temperature, and the steel rolling process can begin. In a reheating furnace, the heat provided to the steel stock is constant.
The reheating furnace can be basically split into five zones: Non-firing, charging, preheating, heating and soaking zones. The energy for heating is supplied by roof and bottom tangential gas burners. According to Trinks 'Continuous furnaces move the charged material, stock, or load while it is being heated. Material passes over a …

The reheating furnace of the steel industry was evaluated in the present study, which uses the gas mixture from coke oven (COG), steelmaking process "Linz-Donawitz" (LDG) and blast furnace (BFG).
Scale formation of steel in the presence of gaseous products of combustion adds to the complexity of the oxidation process in the reheating furnace. A major element in this complexity of scale formation is the inconsistency, which again, is a result of interacting parameters in the reheating furnace. A saving of up to 35 % of steel lost to ...
