Technical field
The utility model relates to the smelting specific equipment, refers in particular to a kind of non-stick steel anti-slag-splashing device of smelting usefulness.
Background technology
Vacuum degassing furnace (VOD) is important stainless steel precision furnace, have and under vacuum state, carry out the oxygen decarburization function, general structure is that ladle is positioned in the vacuum chamber, vacuum chamber is comprised of vacuum tank, anti-splash device, vacuum container cover, and the visual plants such as oxygen blowing device, feeding device, automatic temperature measurement sampling unit, wire feeding apparatus, water cooling plant are installed on the vacuum container cover.The anti-splash device Main Function is to prevent bottom blowing rare gas element, top blowing oxygen and the reinforced molten steel slag splash that causes when the vacuum-treat stainless molten steel.Because the high temperature splashings wash away, scaling loss vacuum tank, vacuum container cover and tightness system between the two, may cause vacuum chamber crackle to occur, thereby so that air enters in the vacuum chamber, vacuum tightness do not reach processing requirement.This anti-splash device mostly is greatly refractory materials and makes, and also has part producer to use the water-cooled copper steel composite board to make.Although yet have the advantages such as fault is less, security is high by the anti-splash device that the material of anti-the material is made, also exist weight large, vacuum container cover is caused larger pressure, make the shortcomings such as cover strain cracking; And the material of anti-the material is in treating processes in the hot environment, self temperature also can be very high, after finishing, processing can produce hyperthermia radiation to surrounding devices, affect peripheral equipment function precision, reduce peripheral equipment work-ing life, main is that refractory consumption washes away in the environment in vacuum, high temperature, the splash of slag molten steel, work-ing life is very short, frequent can reduce the activity duration, and anti-material also can increase steel-making cost as consumable material simultaneously.
The utility model content
The utility model purpose provides a kind of non-stick steel anti-slag-splashing device with low cost, safe and reliable, long-life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of non-stick steel anti-slag-splashing device, it comprises: water-cooled cylinder, several suspension hooks that are wholely set with water-cooled cylinder, the water-cooled loam cake that is used for sealing water-cooled cylinder upper end and the water-cooled supporting cup that is positioned at the water-cooled cylinder below, wherein the inner-wall spraying of water-cooled cylinder has one deck compound coating.
On the basis of technique scheme, further comprise following attached technical scheme:
Described compound coating comprises the antistick layer that is positioned at inboard bonding coat, high-temperature-resistant layer and is positioned at the outside at least.
The bottom side of described water-cooled loam cake is coated with one deck compound coating.
The weighting material that described water-cooled supporting cup is included in circumferential direction is arranged and the interval arranges several back up pads, be filled between the adjacent shore plates and made by refractory materials and be arranged on the back up pad and be several dross nails of angle with back up pad.
Because the utilization of technique scheme the utlity model has following advantages:
With low cost, safe and reliable, long lifetime.Have simultaneously good heat impact strength and high bonding strength, poor with the wettability of molten steel, the effect of obvious anti-stick slag is arranged, reduce the replacement frequency of revolving furnace sublance adapter and revolving furnace sublance shower nozzle, improve converter production efficiency, the potential safety hazard of minimizing equipment and the person has very large economic benefit and use value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is that the utility model is applied to the sectional view in the ladle, the wherein local signal of ladle.
Fig. 2 is that Fig. 1 is along the local vertical view cutaway drawing of A-A line.
Embodiment
Embodiment: shown in Fig. 1-2, the utility model provides a kind of non-stick steel anti-slag-splashing device, it is placed on the ladle 40 with molten steel 50, and comprise water-cooled cylinder 10, several suspension hooks 12 of being wholely set with water-cooled cylinder 10, be used for the water-cooled loam cake 20 of sealing water-cooled cylinder 10 upper ends and be positioned at water-cooled cylinder 10 belows and be positioned at the water-cooled supporting cup 30 of ladle 40 tops, wherein water-cooled cylinder 10 is big top and small bottom frustum of a cone, and its inwall all sprays one deck compound coating 100.The center of water-cooled loam cake 20 has through hole 22, so that the lifting of oxygen rifle.Suspension hook 12 is used for this device is hung on vacuum container cover, with the vacuum container cover lifting.The bottom side of water-cooled loam cake 20 also is coated with one deck compound coating 100.Compound coating 100 comprises the antistick layer that is positioned at inboard bonding coat, high-temperature-resistant layer and is positioned at the outside at least.When compound coating 100 was attached on it in the slag splash, because the water-cooled effect, temperature reduced shrinkage cracking, under action of gravity, can automatically allow slag come off.The utility model is by water-cooled loam cake 20, water-cooled cylinder 10, water-cooled supporting cup 30 and the ladle 40 common spaces that form a relative closure, to prevent towards periphery equipment splash of slag simultaneously.And water-cooled supporting cup 30 contacts with ladle 40 upper limbs, to support the weight of whole device after this device descends with vacuum container cover.
As shown in Figure 2, water-cooled supporting cup 30 weighting material 34 that is included in circumferential direction is arranged and the interval arranges several back up pads 32, is filled between the adjacent shore plates 32 and made by refractory materials and be arranged on the back up pad 32 and be several dross nails 36 of angle with back up pad 32.Wherein back up pad 32 is steel plate, for the bottom skeleton of water-cooled supporting cup 30 directly contacts with ladle 40 upper limbs.Be filled between the back up pad 32 owing to dross nail 36 with by weighting material 34 fillings that refractory materials is made; the molten steel 50 contact injuries that protection water-cooled supporting cup 30 is not piled up by ladle 40 upper limbs; and 36 effects of dross nail are to strengthen the refractory materials tack; back up pad 32 is as skeleton; can protect refractory materials; even and the existence of refractory materials is played the provide protection to this device so that there is molten steel also directly not contact with this device.
Because the utilization of technique scheme the utlity model has following advantages:
Have good heat impact strength and high bonding strength, poor with the wettability of molten steel, the effect of obvious anti-stick slag is arranged, subtract the replacement frequency of Splashproof cover, improve converter production efficiency, the potential safety hazard of minimizing equipment and the person, with low cost, safe and reliable, the long lifetime, have very large economic benefit and use value.
Certainly above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
