BASIC REFRACORY BRICKS
MAGNESITE
BRICK
|
| With
good slag resistance, high refractoriness, its physical property
is better, used in open-hearth furnace, oxygen converters,
electric arc furnace, torpedo, and the basis zone of non-ferrous
metal furnaces. The high-quality magnesite brick is also suitable
to the special zones of hot-work equipments in the alkaline
medium environment. |
