In a reverberatory furnace
, extra castable insulation in the roof and block and board insulation in the upper sidewalls roof was added.
There are the fine, late "texturalist" poems, each a "reweaving of an existing text into another texture, previously only implicit." My favorite is "All the Blue: From the Director's Book of Josiah Spode," the English ceramicist's dramatic recipe for heating a mixture of plaster, borax, and cobalt monoxide in a reverberatory furnace
to create a substance known simply as "blue": but as a large proportion of the colour will persist in ore sunk to the bottom, it will be necessary to pursue the same method with the residue and then-- although the exact duration and quantity of heat is impossible to state for it varies directly with the body of ore, the size of furnace and strength of fire-- without doubt it will yield the remainder of the blue.
Mr Belford said: 'The discovered cementation furnace would have consisted of a large sandstone chest, in an arched brick chamber (a reverberatory furnace
The filter cake is dried, then fluxed and roasted in a reverberatory furnace
The reverberatory furnace
has been replaced by a Teniente converter and a circular electric slag cleaning furnace designed to treat all the slags generated by the converter.
A pusher feeder sends the lead into the plant's reverberatory furnace
, fired with oxy-fuel burners built by American Combustion Inc.
It includes one reverberatory furnace
and three casting machines.
In conventional copper smelting in 1935 (and for about the next 30 years), the usual practice was to first roast the concentrates, then feed the partially desulphurized calcine along with silica flux into a long reverberatory furnace
fueled by burning pulverized coal in air to heat the furnace and its charge up to 1,200 [degrees] -1,300 [degrees] C.
The process used was the traditional one of smelting in a reverberatory furnace
and conversion to copper in Hoboken and Peirce Smith converters.
In conjunction with the molding machine, Talladega Pattern added a new reverberatory furnace
from The Schaefer Group, Dayton, Ohio, to help melting keep pace with molding.
ZCCM has also signed a know-how agreement for the transfer of pyrometallurgical techniques for oxy-fuel burners in reverberatory furnaces
, and for the autogenous smelting of concentrate with the simultaneous conversion of reverberatory furnace
matte using oxygen enrichment of the blowing air in a Teniente converter.
