soaking pits at steel mills manufacturers

After soaking in the pits for several hours the ingots are then lifted out by crane and transported by rail to the blooming and slabbing mills The mechanical working of steel such as rolling forging hammering or squeezing improves it in several ways Get price

The Trainworld City Steel Works and Duluth Works Part 9

So far the soaking pit building is the first and only building of the rolling mills to have this happen yet but others will follow The soaking pit of the Trainworld City Steel Works is actually a bit different than that of the prototype at Duluth and this was done to accomodate certain sizing specifics Get price

Lining walking

A scale-resistant shrink-free ramming compound was developed on the basis of chromite ore electrocorundum fireclay and phosphate bond Industrial trials were carried out with the compounds in steel factories in furnaces with walking hearths in mills 260 and 350/500 The resistance of the rammed linings in the soaking zone of the furnace was twice that of the resistance of chrome-magnesite Get price

Soaking Pit

Soaking pits are necessary to heat up and soak metal ingots to a uniform temperature sufficient to allow passage through the various rolling stages of the mill Steel feed stock to the pits can be hot ingots from BOS plant hot skelps (cast slabs or blooms) from CONCAST plant or cold stock Get price

History of Iron and Steel in Scotland

These comprised a new No2 melting shop with five 60 ton open hearth furnaces with stockyard and producer bench and a new cogging mill bay with soaking pits etc The No 3 'Heavy' Plate Mill which was used for rolling wide plate was dismantled and sent to Dalzell works to be converted into a new No 2 Cogging Mill and a steam hydraulic guillotine provided to cut the slabs to length Get price

Bethlehem Steel

Once cooled the steel ingots were stripped from the molds sent to the soaking pits to be reheated to a uniform temperature and finally sent to various mills for finishing In order to produce a higher yield of usable steel mold men would place metal hot top castings on top of the ingot molds Get price

Steel manufacture

Continuous casting eliminates the need for primary and intermediate rolling mills soaking pits and the storage and use of large numbers of ingot moulds It also increases the yield of usable product from a given weight of steel and processes the steel into a semi-finished form Get price
