Technical instructions

two types of tundish impact plate

1 , casting type ,

use high alumina castable to casting .

2 , machine made type

same as mgo carbon brick , use the machine to make it .

with high melting point of alkaline oxide, magnesium oxide (melting point 2800 ℃) and hard to slag invasion of high melting point carbon materials as raw materials, all kinds of oxide additives.Carbon composite refractory materials with carbon binding agent.

1.High strength

2.Excellent slag resistance

3.High refractoriness

4. Good thermal shock resistance.
