shaft furnace

They were small shaft furnaces using induced natural draught.

Electric arc steelmaking — example of a twin shaft furnace 3.

In the Midrex direct reduction process, iron oxide is fed through the top of a shaft furnace.

The shaft furnace was more efficient, could smelt larger quantities of ore, and was the method of choice.

This will greatly reduce the operating time of the Asarco shaft furnace, which is a major contributor to the site's total particulate releases.

The zinc oxide is thought to have been produced by heating zinc ore in a shaft furnace.

The use of bellows to force a draft into a shaft furnace is usually regarded as the pinnacle of early smelting technology.

This smelting process is carried out in a blast furnace, which is a refractory-lined shaft furnace.

He accomplished this by making possible the long, continuous running of large shaft furnaces in the smelting of argentiferous lead ores.

Shaft furnace for melting aluminum alloys", А."

The particulates contained in the off-gas from the shaft furnace are collected by wet scrubbing and recycled in the process(10).

Most smelting yards used both hearth and shaft furnaces, and produced slag-contaminated "blooms" which were called sows.

At the Direct Reduction plant, pellets are charged in Midrex shaft furnaces after misco-grain screening (less than 5mm).

Calcination processes are carried out in a variety of furnaces, including shaft furnaces, rotary kilns, and fluidized bed reactors.

Emissions from the direct reduction process arise primarily from materials-handling operations, which result in airborne dust, and from the exhaust gases from the shaft furnace.

The direct reduced iron comes from the direct reduction iron-making operation where iron pellets are reduced in a shaft furnace using reformed natural gas.

Shakenoak produced iron-working debris (Cleere 1972), whilst at Wakerley and Mucking there were shaft furnaces.

Strabo and Pliny the Elder both describe a method of roasting the ore in a hearth-type furnace (oxidation), and the shaft furnace (reduction).

Fried Crupp of West Germany having one low shaft furnace with a capacity to produce 30000 M.T. of pig iron per annum.

Presently the Kalinga Iron Works produces 100000 M.T. of foundry grade pig iron by three low shaft furnaces.

A shaft furnace in which metallurgical coke is burned with air and the resulting carbon monoxide reduces lead sinter to the metallic state, producing molten bullion and slag phases.

There is an interesting old limekiln with the duplex Pacold's shaft furnace - unique technical monument from the second half of 19th century - to see in Velká Chuchle:

A refractory-lined vertical cylinder where iron pellets are fed into the top of the shaft furnace through a large number of distributor pipes, which reduce the possibility of size separation and gas channelling.

One is the second-century establishment at Godmanchester, manufacturing both iron and copper goods in a timber-framed workshop with an open front which contained four shaft furnaces and a bowl shaped smithing furnace.
