Abstract

The present invention relates to metallurgical fire resisting material fields more particularly to a kind of hot-metal bottle along castable.Hot-metal bottle designed by the present invention is to regenerate aluminum-silicon carbide brick 49.9%~80%, alumina cement 19.8~50%, sodium tripolyphosphate 0.1~0.2% along castable, including component and mass percent;The regeneration aluminum-silicon carbide brick when hot-metal bottle overhaul by generating with rear aluminum-silicon carbide brick through live directly broken gained, and the particle size after cracking of the regeneration aluminum-silicon carbide brick is in 8mm or less.For the hot-metal bottle that the present invention obtains along castable under the premise of guaranteeing compressive resistance, price is significantly lower than existing product.

Description

A kind of hot-metal bottle is along castable
Technical field
The present invention relates to metallurgical fire resisting material fields more particularly to a kind of hot-metal bottle along castable.
Background technique
Hot-metal bottle is blast-melted collection, the important equipment of iron making inside transport and steel mill.Water pot edge and permanent layer position Molten iron is not contacted, fixed indentured brick, under the heat radiation and conduction of heat of molten iron, about 700 DEG C of operating temperature are played the role of. Traditional hot-metal bottle is generally high alumina castable along castable, can be divided into non-renewable resistance to material series and regeneration according to raw material type Resistance to material series, the non-renewable series of products of resistance to material add calcium aluminate water by the aluminium silicon systems raw material such as bauxite clinker, mullite, flint clay The refractory materials such as mud, micro mist, additive composition, has the characteristics that intensity is high, but cost of material is excessively high;Resistance to material series is regenerated to produce After product are by obtaining finished product waste material after corundum reworked material, alumina reworked material, the recovered working process of mullite reworked material, then add aluminium The refractory materials such as sour calcium cement, micro mist, additive composition, cost has certain advantage, but its intensity is lower, and regenerates resistance to Material is had bad luck, there is still a need for costs for working process.
Summary of the invention
In order to solve problem above, the object of the present invention is to provide a kind of hot-metal bottle edge casting low in cost, intensity is high Material.
To achieve the above object, the present invention designed by hot-metal bottle be along castable, including component and mass percent, Regenerate aluminum-silicon carbide brick 49.9%~80%, alumina cement 19.8~50%, sodium tripolyphosphate 0.1~0.2%;The regeneration Aluminum-silicon carbide brick when hot-metal bottle overhaul by generating with rear aluminum-silicon carbide brick through live directly broken gained, the secondary aluminium The particle size after cracking of silicon carbide carbon brick is in 8mm or less.
Preferably, the regeneration aluminum-silicon carbide brick includes the regeneration aluminum-silicon carbide brick that granularity is 8~0.5mm With granularity in 0.5mm regeneration aluminum-silicon carbide brick below, the granularity is the regeneration aluminum-silicon carbide brick conduct of 8~0.5mm Refractory aggregate uses, and the granularity is used in 0.5mm regeneration aluminum-silicon carbide brick below as brickwork joint filler.
Hot-metal bottle of the invention generated when hot-metal bottle overhaul is directly utilized along castable with rear aluminum-silicon carbide brick, use Aluminum-silicon carbide brick is there are metamorphic layer and a small amount of residue afterwards, but 700 DEG C of its fusing point >, meets tank along castable requirement, because This is without individually handling metamorphic layer and residue;And after crushing with rear aluminum-silicon carbide brick brick, partial size be 8~ For the oversize of 0.5mm as refractory aggregate, partial size is used as 0.5mm screenings below can be directly used in filling brick at the scene Seam;Alumina cement can be used as fine powder and be filled to the regeneration aluminum-silicon carbide brick of 8~0.5mm, improve intensity.
The present invention has the advantages that
(1) compared with existing hot-metal bottle is along castable, hot-metal bottle is directly utilized along castable in hot-metal bottle of the invention Generated when overhaul with rear aluminum-silicon carbide brick, and without carrying out recycling working process to rear aluminum-silicon carbide brick, make It is crushed, sieved with scene, then directly utilized, saved and transported with rear resistance to material, working process cost.
(2) it is of the invention with rear aluminum-silicon carbide brick after scene is directly broken, oversize work that partial size is 8~0.5mm For refractory aggregate, and partial size is to contain a small amount of carbon and silicon carbide in the oversize of 8~0.5mm, and scum can be effectively prevent viscous It is attached, reduce scarfing cinder frequency, improves hot-metal bottle running efficiency.Partial size is used as 0.5mm screenings below can be straight at the scene It connects for filling brickwork joint.
(3) present invention increases the dosage of alumina cement, and alumina cement can be filled uniformly as fine powder to broken partial size To promote the intensity of castable in the regeneration aluminum-silicon carbide brick of 8~0.5mm.
Specific embodiment
For a better understanding of the invention, invention is described in detail below with reference to specific example.
Examples 1 to 7
Hot-metal bottle is shown in Table 1 along the component and its mass percent of castable in Examples 1 to 7:
Table 1
Wherein, regeneration aluminum-silicon carbide brick is to generate when hot-metal bottle overhaul with rear aluminum-silicon carbide brick, through it is live directly Broken, being crushed to partial size is 8mm particle below.The above component is uniformly mixed in blender according to the proportion, adds water and stirs 5 Minute, it can construction usage after discharging.
Examples 1 to 7 and 2 are shown in Table with the performance of existing product:
Table 2
Due to the regeneration aluminum-silicon carbide brick in the present invention be crushed using scene with rear aluminum-silicon carbide brick, Screening gained is transported without having saved to other working process is carried out with rear aluminum-silicon carbide brick with rear resistance to material, working process Cost, therefore the cost of Examples 1 to 7 is significantly lower than traditional hot-metal bottle along castable.
In addition, the present invention increases the dosage of alumina cement, alumina cement can be filled uniformly as fine powder to broken kernel Diameter is to increase the intensity of castable in the regeneration aluminum-silicon carbide brick of 8~0.5mm, and being crushed partial size is 0.5mm secondary aluminium below Silicon carbide carbon brick directly fills brickwork joint for scene, further increases the intensity of castable, therefore, Examples 1 to 7 castable Intensity is above traditional hot-metal bottle along castable.
In conclusion as can be seen from Table 1 and Table 2, the hot-metal bottle that the present invention obtains have along castable it is cheap, The high advantage of intensity.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
