Regarding heat-resistant steel
Thread Content
What kind of steel should be used to manufacture containers that can withstand temperatures above 1,800 degrees Celsius? Let’s discuss it together. This post was last edited by bht11 on 2007-9-4 16:12]
In what situations is the container you mentioned used?
For various applications, the key is to have materials that can withstand such high temperatures. Or what methods can be used to make the material capable of withstanding such high temperatures.
It is estimated that no steel material can withstand 1800 degrees; such high temperatures definitely require composite materials other than steel. Otherwise, there would be no need to install thermal insulation tiles on the outside of the American space shuttles.
I support the opinion from the fourth floor. The commonly used heat-resistant steel at present is austenitic heat-resistant steel, which possesses high strength at high temperatures as well as good corrosion resistance; its maximum operating temperature can reach around 700°C. Therefore, to withstand temperatures of 1800°C, it is necessary to add heat-resistant materials (refractory bricks or sprayed heat-resistant materials) on the outside of the steel, as well as to install water-cooling walls.

I saw that the steel plant uses carbon steel cylinders, which are lined with refractory bricks on the inside
It was a colleague who asked; I don’t understand it, so I’m turning to all of you experts for help. :lol
Generally, refractory bricks made of silicon-aluminum materials need to be laid on the fire-resistant side, and then comes the steel shell section; by the time one reaches that section, the temperature has already dropped to six or seven hundred degrees Celsius.
I have seen heat-resistant steel used under conditions of 1200 degrees, but with water cooling on the outside
No one can save Fe-based alloys at 1800 degrees; Ni-based alloys are somewhat better in that regard.
After checking, Ni-based alloys don’t require such high temperatures either
