Ladle refractory materials commonly used in the following categories

Ladle refractory materials commonly used in the following categories:
(1) clay brick
The content of Al2O3 in clay bricks is generally between 30 and 50%, and the price is low.Mainly used for ladle * layer and ladle bottom.
(2) high alumina brick
The Al2O3 content of brick is between 50 and 80%, which is mainly used in the working layer of ladle.
(3) the wax stone brick
The brick is characterized by high Si02 content, generally more than 80%, better erosion resistance and integrity than clay brick, and does not hang slag.Often used on ladle wall and bottom.
(4) zircon bricks
The brick is mainly used for ladle slag line.The content of ZrO2 in bricks is generally between 60 and 65%.Its characteristics are good erosion resistance, but the price is higher, generally not used.
(5) magnesium carbon brick
The brick is mainly used for ladle slag line, especially for multi-furnace casting.The MgO content in bricks is about 76%, and the C content is between 15 and 20%.It is characterized by low erosion resistance to slag, good erosion resistance and spalling resistance.
(6) aluminum-magnesium castable
This castable is mainly used in the ladle body. Its characteristic is that under the action of molten steel, MgO and Al2O3 in the castable react to form aluminum-magnesium spinel, which improves the slag resistance and thermal shock resistance of the lining.
(7) aluminum-magnesium-carbon brick
This brick is a kind of brick developed on the basis of aluminum-magnesium castable, used for ladle lining, with long service life.
(8) air brick
At present, the brick materials used in ladle can almost be made into the corresponding non-brick.It is characterized by relatively simple manufacturing process and low price.Brick itself has a certain mechanical strength and erosion resistance, but also convenient for construction masonry.
If the ladle itself is also used for refining, you can also choose MgO - Cr2O3 Al2O3 system and MgO - CaO - C system refractories, mainly: magnesium-chrome brick, magnesium-chrome aluminum brick, dolomite brick.
Also pay attention to, in pouring boiling steel, should try to avoid the selection of graphite brick and castable, or lining service life is low.website:www.haloong.com email:ivy@haloong.com whatsapp:+8618530012598
