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 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
These ingots are first heated to about 1200 C in soaking pits and then passed through rollers to produce intermedials shapes such as blooms The blooms are rolled to billets and the billets to the desired sections like flat square hexagonal angle I U etc The Get price

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
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
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

Iron and Steel mills can basically be broken down into two process areas ie the metallurgical plant and the mills Metallurgical Plant In the metallurgical area coal coke iron ore manganese and other basic core materials from which steel is made are brought into the plant Get price
Soaking Pits For Steel Ingots On The Successful Rolling These pits are commanded by an ingot crane by preference so placed in relation to the blooming mill that the crane also commands the live rollers of the mill Each pit is covered with a separate lid at the floor Get price
