Temperature of a Blast Furnace - The Physics Factbook

The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

Electric Smelting Furnace of Ore

They decided that, excepting iron ores, aluminum, and ferroalloys, electric smelting was in the experimental stage. It is the purpose of the present paper to survey the technical and economic changes that have taken place and to determine whether electric smelting of nonferrous ores offers any more promise today than 20 years ago.

Lead Fumes let's settle this. - Cast Boolits

Jul 05, 2011 · Over the years I have seen guys say that one needs to be carefull of the lead fumes given off by molten lead. There were various authorities also that claimed bunk on this. I did some searching and from all I could find there are no fumes from lead unless it is very very hot. I was reading Glens F's book and he referred to lead fumes. He is often mentioned as THE authority on casting.

Flux lead in the pot? | The High Road

May 03, 2006 · Lead sheeting is pretty much pure lead, but after smelting a good bit, I'd suggest anyone keep their temperature for smelting around the temperatures above, because the lead just smelts better in that range. Jump up above that and it's more aggravating. You won't hurt the lead, but it's easier to work with at lower temps.

Melting Point of Metals & Alloys - American Elements

What is a melting point? The melting point of a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure; at the melting point, the solid and liquid phases exist in equilibrium. A substance's melting point depends on pressure and is usually specified at standard pressure in reference materials.
