We just finished construction of 2 new kilns for hollow insulators and finished test firing . those 2 kilns are 400 CBM each , all the firing process are auto- controled .
and the whole control system are from Siemens , the kiln design working period is 10 years without big repairation . the kiln inside temperature different are less than 2 ℃.
so during the firing process , the inside temperature are even , it will lead porcelain quality are more reliable and stable .
after testing we found , the product mechanical strength improved 5% compares with old kiln , and the firing qualified rate improved 6% .
we are very satisfied with the performance of new kiln . it will be great help for us to keep improving product quality and customer's satisfication.
