Abstract
The utility model relates to a bottom pour brick for the steel grade pouring, in particular to a zirconium layer coated composite bottom pour brick, solving the defect that the structural constituent of the existing bottom pour brick is easy to carry in molten steel so as to affect the quality of the molten steel when pouring is conducted. The zirconium layer coated composite bottom pour brick is characterized in that a layer of zirconium coating material is coated on the inner wall of the bottom pour brick. The bottom pour brick can prevent the molten steel and the fireclay refractory of the base material from contacting with each other and can prevent the inclusion of the steely Al 2 O3 from increasing because the substance which is full of Al 2 O3 is washes and conducts melting loss when the cast-ingot operation is conducted; the zirconium layer coated composite bottom pour brick is mainly used for the pouring of the steel grade which is sensitive to the inclusion.
Description
Technical field:
The utility model relates to a kind of steel grade cast and uses bottom pouring brick, and particularly a kind of compound bottom pouring brick of zirconium matter coating is applied to the steel grade cast of inclusion sensitivity is used.
Background technology:
In order to improve production efficiency to the responsive steel grade of inclusion, require in the ingot blank of steel the inclusion total amount will be less, big or small rank is low, also requires inclusion in rolling or yielding and unlikely steel wire fracture when drawing.
Mould pours down common use of notes method and is rich in Al
2O
3The bottom pouring brick of clay matter, high alumina matter or be rich in the magnesia bottom pouring brick of MgO.The position of these refractory materialss contact molten steel, in case enter in the molten steel after the molten damage of molten steel scouring because of being subjected to, become ingot after, always have the nonmetal inclusion in the fine particles body formation steel of part refractory materials.This nonmetal inclusion is often with α-Al
2O
3, harder and on-deformable mineral form such as mullite, periclasite, forsterite exists, and can have a strong impact on the quality of steel in the rolling or pulling process of steel.
Summary of the invention:
The utility model technical issues that need to address are that the prevention molten steel contacts with the fireclay refractory of base material in the pouring molten steel process, prevents when the ingot casting operation, because of rich Al
2O
3Material is washed away melting loss and is caused Al in the steely
2O
3Be mingled with increase, a kind of compound bottom pouring brick of zirconium matter coating is provided.
For solving the problems of the technologies described above the technical solution of the utility model: a kind of compound bottom pouring brick of zirconium matter coating is coated with one deck zirconium matter coating at the bottom pouring brick inwall.
Described zirconium matter paint thickness 1~2mm.
The components by weight of described zirconium matter coating is ZrO
220 ~ 70%, SiO
225~75%.
Advantage of the present utility model is: by being coated with one deck zirconium material at the bottom pouring brick inwall, can stop molten steel to contact with the fireclay refractory of base material, prevent when the ingot casting operation, because of rich Al
2O
3Material is washed away melting loss and is caused Al in the steely
2O
3Be mingled with increase.Not only improve the work-ing life of bottom pouring brick but also can improve the quality and the production efficiency of steel.
Description of drawings:
Accompanying drawing is the utility model structural representation
Among the figure: 1-bottom pouring brick, 2-zirconium matter coating
Embodiment:
Embodiment 1, at first prepares zirconium matter coating, with the ZrO of 35 grams
2With 65 gram SiO
2Be made into zirconium matter coating routinely,, be coated with one deck zirconium matter coating 2, thick coating 1.3mm at bottom pouring brick 1 inwall with reference to accompanying drawing.
Embodiment 2: at first prepare zirconium matter coating, with the ZrO of 60 grams
2With 40 gram SiO
2Be made into zirconium matter coating routinely,, be coated with one deck zirconium matter coating 2, thick coating 1.7mm at bottom pouring brick 1 inwall with reference to accompanying drawing.
