You require a lot of heat and a vessel (usually ceramic) that can withstand the heat.
You'll also require some kind of protective gear, usually a robot, that can withstand the high temperatures.
No. Lava is generally not hot enough to melt steel.
Steel is an alloy, not a purified metal; but sometimes the excess of phosphorous, sulfur, carbon etc. in the melt need to be deleted.
No, chlorine gas cannot melt stainless steel.
It can heat it enough to weaken it, but it won't melt it.
which chemical is used to melt the iron
The melting point really depends on the type of steel. But no type of steel would usually melt at 1000 degrees (Celsius or Fahrenheit).
A steel or iron works, where they melt or cast steel or iron - metals
All-Steel Equipment Company was created in 1912.
Yes, stainless steel can melt in a fire if exposed to high enough temperatures. The melting point of stainless steel is around 2,500-2,700 degrees Fahrenheit.
To know how fast this will melt you need to know the amount of stainless steel and the temperature of the stainless steel at the beginning. Then using the formulas of energy needed to heat it (Cp, I think) and melt it (enthalpy) you can calculate when it will melt.
On 1375 °C.
The amount of energy needed to melt steel is approximately 1,650-1,800 kWh per metric ton, depending on the type of steel and the specific melting process used.
