An Automation Master Plan was conducted to achieve the control optimization of a blast sintering process based on a DwightLloyd machine In the pursue of this goal was necessary to use an engineering and scientific approach in order to identify and analyze all the factors influencing the production rate product quality and environment protection among others

126 Primary Lead Smelting 1261 General15 Lead is found naturally as a sulfide ore containing small amounts of copper iron zinc precious metals and other trace elements The lead in this ore typically after being concentrated at or near the mine see Section 1218 is processed into metallurgical lead at 4 facilities in the U S

the process proceeds to the sintering stage The end of sintering is defined as the time at which the peak exhaust gas temperature is measured indicating that the flame front has travelled all the way through the sinter cake An optional cooling cycle may be included after this where cold air continues to be drawn through the sinter cake

Sinter Plant The function of the Sinter Plant is to supply the blast furnaces with sinter a combination of blended ores fluxes and coke which is partially ‘cooked’ or sintered In this form the materials combine efficiently in the blast furnace and allow for more consistent and controllable iron manufacture

Sintering is a process by which a mixture of iron ores fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition quality and granulometry to be

The leadconcentrate contains sulphur which is removed during sintering as sulphur dioxide and converted into sulphuric acid in the Acid Plant The acid is pumped to Material Handling West where it is stored prior to shipment In general the site consists of a Sinter Plant Blast Furnace Lead Refinery Acid Plant and Material Handling West

Zinc Zinc is often found in nature together with lead in sulfide ores The metals are separated during refining As zinc is resistant to corrosion and easy to apply much of it is used to protect iron and steelbased products Uses of zinc Zinc is used as coating to protect iron and steel from corroding in the atmosphere water and soil

Jan 01 2012 · Similar to sintering pelletizing is another widely used process to agglomerate the iron ore Sinter plants are usually located near the blast furnace plant but pelletizing plants are often located near the mining site Some works have both pelletizing and sintering plants at the smelter sites 113222 Green Pellets

The drum is usually lined with wear resistant material During operation 80 of the container is filled with grinding bodies and the starting material Here vibratory motion is obtained by an eccentric shaft that is mounted on a frame inside the mill The rotation of eccentric shaft causes the drum of

Abstract Processes for continuous production of a thin metal strip in particular a steel hot strip directly from a metal melt and with a strip cast thickness of 10 mm by the rollcasting process The cast metal strip is fed for inline thickness reduction and then to a storage device To achieve a highquality hotrolled metal strip with flatness tolerances comparable to those which can

Double drum rotary vacuum heat treatment furnace Double drum rotary vacuum heat treatment furnace can be used as quartz sand drying stove quartz sand water broken furnace and quartz sand chemical purification furnace RGO double drum rotary vacuum heat treatment furnace is suitable for heat treatment of granular materials and powders which ca

Brackett Green double entry drum screens are engineered to suit the particular operating conditions water levels and design codes of any installation site This may include seismic qualification or designs for nuclear safetyrelated cooling water duty

Last years 7 yearonyear fall in output at the smelter was due to a 38day planned blast furnace maintenance outage in the second quarter and a blast furnace shutdown in December when the company chose not to operate the sites old sinter plant in order to further support reducing lead in air emissions which ended the year below the

CONTINUOUS STAINLESS STEEL LINES EFFICIENT RELIABLE AND ECONOMIC Stainless lines from Primetals Technologies combine the traditionally separate processes of rolling annealing and pickling skin passing and leveling in one integrated processing line

1 On behalf of the Government of Ethiopia UNEP as the lead implementing agency has submitted to the 68th Meeting of the Executive Committee stage I of an HCFC phaseout management plan HPMP at a total cost as originally submitted of US 389900 consisting of US 210000 plus agency support

Huge amounts of cooling water are needed in the industry The use of drinking water for this purpose would result in unacceptable costs In addition it would be a sheer waste of this scarce resource because for most areas of application filters for river water prepare and provide sufficient cooling water for this purpose The ideal choice are basket strainers or automatically cleanable

On this regard Alfa Laval Olmi has supplied many packages for hydrogen and fertilizer plants including site survey and services during package erection Alfa Laval Olmi process gas boiler packages are used in demanding processes in petrochemical plants refineries oil and gas production facilities and power stations around the world
