A new system has been proposed for the recuperation of waste heat energy in steel mill soaking pit furnaces. The new system offers efficiency increases from 130% to 360% above conventional recuperation systems. This is possible through the combination of a low leakage, compact ceramic recuperator an
While attention in the iron and steel industry has been focused on the study and analysis of the flow of materials through the main productive units (blast furnaces, steel works, and rolling mills), the analysis of this flow through the nonproductive units (the mixer and soaking pits) is
SOAKING PITS. Soaking pit furnaces are basically used for heating of aluminum logs in aluminum rolling mill, extrusion plant fabrication plant as
This process begins with pre-shaped steel slabs, which are reheated in a soaking pit. The steel passes through a series of mills the blooming mill, the roughing mill, and the finishing mill, which make it progressively thinner. Finally, the steel is wound into coils and transported elsewhere for further processing.

Heating is by means of resistors in coke-filled troughs which run the full length of the pit. The soaking pit bay is served by two cranes designed to handle ingots up to 40 tons. ROLLING MILL. The mill is a 2-high, high lift reversing mill, with each roll individually driven by a 7,250 hp motor at 50/80 rpm.
Aug 05, 2009 Van Aken points out that segregation and banding in steel has always existed, but in the past it was economically feasible to homogenize the steel in large soaking pits. This is no longer the practice in most steel mills as most steels are continuously cast, and soaking pits would not be considered because the operation adds cost (equipment ...
Rail-tractor operators transport hot ingots and slabs from soaking pits to conveyors that take them to rolling mills. There, massive steel rollers squeeze the hot ingots into specified shapes. In five minutes, a 25 x 27 ingot can be rolled into a bloom with a 9 x 9cross section or into a 4 billet. Roll builders and mill utility ...
heats and of many different types of steel may be in the soaking pits at one and the same time, their only identification being a mark on the inspectors chart. Only the greatest care at this point can prevent the occurrence of mixed steel, i.e., the intermixing of different kinds of steel into the rolling of a particular product.
High Temperature Soaking Pit Cable is constructed for use in high temperature applications as a multi-conductor power cable. ThermoTrex is especially suited for hot material contact, molten splash and mechanical abuse. Widely used in steel plants for slag and teeming ladle car cables.
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).
Nov 04, 2006 Fully killed steel, at least where I worked, had a minimum hold time of 4 hours, and some grades also had a hold time after they were stripped. Generally, though, the idea was to get the steel to the soaking pits and get it charged as quickly as possible. This meant that less time and energy was required to get it hot enough to roll.
Soaking Pits For Steel Ingots. On The Successful Rolling Of Steel Ingots With Their Own Initial Heat By Means Of The Soaking Pit Process. By Mr. JOHN GJERS, Middlesbrough. Footnote Paper read before the Iron and Steel Institute at Vienna. When Sir Henry Bessemer, in 1856, made public his great invention, and announced to the world that he was able to produce
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.
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 1300C.
Constructed after the Edgar Thomson Works (1875), and the Homestead Works (1884), the Duquesne Works was the site of numerous technological innovations significant in the history of the American steel industry. The mill was the first to employ the direct process by which ingots were rolled directly from the soaking pits without being reheated.
This paper considers the soaking-pit/rolling-mill complex as a queueing system in which the soaking pits are viewed as units circulating a cyclic queue, and the rolling mill as the service station. A simulation model representing the pit-mill system is developed (1) To predict the improvement in the capacity of the system through adding more pits
Oct 03, 2017 When the hot steel was ready for transformation hot -metal crane operators and steel pourers worked together to mold the steel into blocks called ingots. Charger operators were responsible for moving the steel ingots into soaking pits, where they were reheated for rolling. The steel stayed heated at temperatures of up to 2450 F for up to 14 hours.
Soaking-pit craneclamping crane) is special lifting equipment in rolling ingot soaking pit workshop , it is able to efficiently complete the cold steel ingot into soaking pit, and will complete the red-hot steel ingot heating took out and put into rolling roller, at the same time complete the soaking pits pit furnace slag, cleaning and ...
Soaking-pit overhead crane this kind of crane is usually used to load, unload, move and lift steel plate slab, section material and other types of materials within the fixed span in steel mill, shipyard, stock yard etc.It is especially adaptable for occasions to lift and move slab of different sizes. The materials are different in size and weight, and the crane can adopt different clamps
different types of steel mills, and each has responsibilities that are important. Some of the more interesting job titles include ... Cinderman removes cinder from under the soaking pits Blooming mill roller directs and controls the operation of a blooming mill to
Feb 04, 2019 Inside the soaking pits, the temperature would reach 2250 Fahrenheit, and the venting stacks helped to equalize the internal and external temperatures of the steel ingots before they were sent to the rolling mill. The steel industry collapsed in the 1980s. Thousands of Pittsburghers lost their livelihoods and moved away, and the mills were ...
As an example, additional soaking pits which prepare steel ingots for primary rolling can also increase primary mill output but at a cost of $750,000 a pair to install. The paper describes an analysis of policies for charging ingots into the soaking pits. The work is a continuation of research on the capacity of the soaking pit-rolling mill
Typically located near steel mill departments that specialize in finished products, JL Steel had many soaking pits on both the South Side and Hazelwood sides, including by the blooming mill and strip mill. Soaking pit jobs include The bricklayer keep the soaking pit lining in good condition as well as hot metal cars, runner and troughs ...
Soaking Pits The soaking pits are equipped with burners to provide heat when necessary. Primary Rolling Mills Also called a blooming mill, or a slabbing mill, these mills consist of a varying number of rolling stands, from one to twenty, that shape the hot steel into the desired semifinished shape.
