At the very beginning, clay brick is used for building
ladle. However, as the ton steel consumption is high, it has been taken place
by unshaped ramming mass. The integral ladle built with ramming mass was
characterized with longer service life and lower ton steel consumption, and
labor amount is also less.
However, some small steel plants cannot melting molten
steel continuously, and with integral ladle it is neither convenient to handle nor
convenient to replace well block. So if we still insisting on using ramming
mass to build ladle, then energy waste will be huge.
What is worse that the service life of a ladle will be only 8-10 heats, and
bleed-out will happen frequently.
In order to solve those problems, Henan
Xinmi Changxing Refractory Material Co., Ltd. started to do some researches and
then successfully manufactured magnesia carbon bricks. The magnesia
carbon brick made by Changxing Refractory has the following characteristics.
Using fused magnesite,
high purity magnesium sand and graphite as raw refractory material, and then through
high-pressure molding and low temperature treatment finally we made the
magnesia carbon brick. The bricks can be used for both ladle and EAF, and whose
service life is not less than 100 heats for ladle, and 120 heats for EAF.
What is more, Changxing Refractory not
only provides products, but also dispatches engineers to help clients build furnace
to guarantee our magnesia carbon bricks reach the service life we just stated.
