Reheat furnaces heat the slabs to about 1200 °C, which makes the steel suitable for hot rolling. During this reheating process temperature uniformity within the slab is very important. A detailed understanding of the reheating process is hence, important both from the perspective of product quality and energy use.
Reheating furnace in steel plants Steel that is transported from a production plant to another location, for instance a facility for annealing, requires reheating as they are transported cool. The two reheating furnaces at SSAB operate at a rate of 300 t/h of steel and at MW. The steel is rolled in from one end of the

The finer the grinding of coal, the more efficient its combustion. The total time required from entry of a coal particle to a furnace to combustion of the particle is very short. This time, however, is dependent on various factors. The heart of a pulverized coalfired boiler is the pulverizer, also known as the mill.

Most hazards in rolling process arise from coming in contact with moving hot material, falling etc. Second threat is from emissions of reheating furnaces whichcontain toxic gases such as carbon monoxide, Sulphur dioxideNOx, etc. Also leakage of fuel gas like producer gas, Piped Natural Gas (PNG), Coal Bed Methane (CBM) etc is a constant threat. 2.

Reheating furnaces After the continuous casting (see Fig. 1), the metal is split into slabs, billets or booms, which must be reheated in reheating furnaces up to 1250 °C before milling. An example of recent furnace, with digital control and lateral burners is shown in Fig. 3. Fig. 3. Example of reheating furnace for slabs, with lateral burners.

In most of the SRRM units, a 4inch pipe is used as a burner for pulverized coal. This 4inch pipe is inserted into the front and side walls of the reheating furnace. Only primary air in ambient temperature is used for combustion in such conventional burners and the airfuel ratio is neither monitored nor controlled.
Using O 2 as an oxidizer has been applied to batchtype furnaces for fuel economy. The O 2 using combustion technology, however, has some disadvantages such as the corrosion of a furnace perimeter wall or high NO x concentrations in the case of the surrounding air intrusion into the batch furnace. However, the O 2 concentration in the combustion air is optimal near 30% because the ...
The iron and steel industry accounts for 14% of the world's industrial energy use [4] and relies to a great extent on fossil fuels, for example, coke is used in blast furnaces, and natural gas is used in reheating furnaces and basic oxygen furnaces while oil and liquefied petroleum gas (LPG) are used as fuel in reheating furnaces. Ultra Low CO
A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
