Application of ceramic thermal insulation board on shift converter

     This issue we will continue to introduce use ceramic thermal insulation board as shift converter’s lining and change external insulation to internal insulation. Below are the details:

4. Material selection and furnace preheating process.
(1) Material selection
It is required that the high temperature adhesive has strong bonding performance at room temperature and high temperature, the bonding time is 60~120 seconds, and the high temperature compressive strength is high. The ceramic thermal insulation board should meet the following conditions: bulk density 220~250kg/m3; shot content ≤ 5%; moisture content ≤ 1.5%, operating temperature ≤ 1100 ℃.
(2) Furnace preheating process
Furnace preheating can test the heating, air circulation, water cooling system, working temperature and manufacturing quality of the furnace, so a scientific and reasonable furnace preheating process must be formulated.
