Steel - Steel - Slabs and blooms: Cast ingots, sometimes still hot, arrive at slabbing and blooming mills on railroad cars and are charged upright by a special crane into under-floor soaking pits. These are gas-fired rectangular chambers, about 5 metres deep, in which four to eight ingots are simultaneously heated to about 1,250° C (2,300° F).
This furnace is for holding hot steel ingots to equalize their temperature before they are hot-rolled in a steel-making 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.
The mill can roll round and square section sizes from 12 to 80 mm, flats from 40 to 120 mm width and 6 to 20 mm thickness. The shop is also equipped with auto controlled pusher type reheating furnace and roll cutting/grinding facilities. Radial forging

A furnace is an equipment to melt metal for casting or heat materials for change of shape (rolling, forging etc.) or change of properties (heat treatment). In the case of Steel rerolling mill, a furnace is used for heating the raw material, ingots or scrap to a temperature of around 1100
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
Reheating Of Ingots. The Soaking Pit Although the stripped ingot may be at a glowing red heat as it comes from the mould, it cannot be rolled because the interior is yet liquid and the solid exterior would merely disrupt and allow the liquid interior to squirt out under the pressure of the rolls.
Over the years many important hot strip mill innovations have been developed, a selection of which is listed below. Walking beam slab reheat furnaces in place of pusher furnaces for improved slab heating and reduced slab skid marks. Furnace slab extractors in place of furnace dropout chutes for reduced equipment damage and slab defects
