Fig. 38. Soaking Pit for Steel Ingots. It frequently happened that ingots became too cold before they reached the pit, due to unavoidable delays, to be hot enough for rolling after they were "soaked." This condition necessitated some way of supplying external heat to the pits. The necessity of heating soakingpits has gradually developed the ...

Soaking pits. The purpose of the soaking pit is to heat the steel ingots to a uniform temperature throughout. The ingots must be of even temperature throughout so that they are uniformly plastic and can be rolled or shaped properly. They must also be uniformly plastic to prevent possible damage to the heavy machinery of the mills. The soaking ...

Reheating Furnaces and their Types. Reheating furnaces are used in hot rolling mills to heat the steel stock (Billets, blooms or slabs) to the rolling temperatures of around 1200 deg C which is suitable for plastic deformation of steel and hence for rolling in the mill. The heating process in a reheating furnace is a continuous process where ...

This furnace is for holding hot steel ingots to equalize their temperature before they are hotrolled in a steelmaking or rolling mill complex. Normal practice is to charge ingots into the soaking pits immediately after stripping from the moulds whilst they are still hot. Soaking pit temperatures are generally controlled at 1300°C. Each pit may hold several ingots and serves to bring the ...

As the ingots are being fed to the mills every few minutes but the heating and soaking cycles take hours (ingots weigh several tonnes), many soaking pits are needed to ensure availability of material to the mills 24 hours a day. A soaking pit, see Figure 1, is a thermally insulated chamber with a top sliding lid to add or remove ingots.

It only took minutes for the caster to turn molten steel into slabs, replacing the traditional steps of producing ingots, reheating them in the soaking pits and then rolling them into coils. The twostrand No. 1 Caster was the heart of an integrated system aimed to improve quality and produce more sophisticated grades of steel.

The ingots are placed in soaking pits (ingot reheating furnaces) to bring them up to a uniform temperature before being passed to the primary mills, which then begin to roll them into the required shapes. However, most modern steels are now continuously cast. Different design principles are used for casting strands of different cross sections.
