Electric furnaces utilize various thermal insulation materials, and mica is a suitable choice because it can withstand temperatures of up to 1000 degrees Celsius.
The photo shows thin phlogopite mica sheets after an 850 °C fire test. The resin is melting and evaporating, but the mica remains intact. Therefore, mica is a suitable insulation material for furnaces.
Foundries produce metal castings of varying quality. Properly completing this process requires maintaining constant temperatures. To do this effectively, the proper insulation must be used to prevent heat loss while also protecting individuals working in intense heat.
Consequently, mica-based insulation materials support metalwork processes and sound thermal management.
We manufacture insulation mica material and provide a range of translucent substance laminates and microporous insulation products to support metalworking processes and protection.
Mica has certain technical benefits for metalworks and the industry. It extends the lifetime of linings by acting as a superior slip plane. This suggests that the liner has free movement through enlargement and contraction, thereby reducing the likelihood of cracks appearing.
It also shields the coil grout and chamber casting, ensuring less stress through free movement and preventing the blunder plane from acting during the relining process.
There are also cost advantages to using translucent substances in foundries, such as improving turnout and relining speeds while reducing production time. There is also the potential for the pricey arm to the coil grout.
