Taphole Mix is a functional refractory material that used for the blast furnace. It is just like a valve in the blast furnace. Taphole was opened when molten iron poured, and block up after it. At the same time, must insure its sufficient time.
Characteristic of GDT- 8, GDT-11:
(1.) Good conglutination.
Taphole Mix that throw into the taphole must conglutinate the former Taphole Mix well and form a complete unit to prevent the aperture.
(2.) Good sinter.
Taphole Mix could sinter in the low, middle and high temperature and block up the taphole in time to protect the lining bricks of furnace.
(3.) High abrasion and corrade.
Not enlarge the aperture of taphole. Ensure 150~180 minute/time, reasonable times should be 8~10 time/day. Lighten labour intensity, decrease the consumption of raw material and at the end reduce the cost
