Description
Technical Field
The utility model belongs to the technical field of the oxygen lance and specifically relates to a ceramic coating oxygen lance.
Background
At present, most domestic steel casting plants need to transport the steel ladles back to a smelting workshop after the steel ladles are cast. The ladle returns to a smelting workshop after being poured for a long time, which easily causes more steel slag to adhere to the surface of the air brick at the bottom of the inner side of the ladle and the water gap, so that the oxygen lance must be used for cleaning the red slag generated by condensation on the surface of the air brick and in the water gap. The number of the casting furnaces in the smelting workshop every day is large, the use and cleaning times of the steel ladle are large, and the oxygen lance belongs to an article easy to burn and damage, so that the using amount of the oxygen lance is large.
Because the production environment is relatively high, the oxygen lance without the coating is easy to be oxidized and deformed when the stemming at the furnace mouth is burnt, so that the opening angle is inaccurate, the effect of the molten iron mouth is influenced, and therefore, the oxygen lance production equipment with the coating is urgently needed.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical purpose, the utility model provides a ceramic coating oxygen lance coats through the surface at the oxygen lance, paints ceramic coating in body outside and inside, can effectively reduce the oxidation problem of oxygen lance to simple structure easily operates, strengthens the life of oxygen lance, improves production efficiency, reduces the problem of wastrel.
In order to achieve the above object, the utility model provides a following technical scheme:
ceramic coating oxygen lance, including the body, ceramic coating has been paintd to the inside and outside surface of body, ceramic coating divide into external coating and undercoating, the one end of body is equipped with helicitic texture, helicitic texture and body are as an organic whole, adhere to the surface of body, the one end of body is for not having the coating, it is equipped with the certain distance with helicitic texture to not have the coating.
The utility model discloses further improve, the overall structure of body is straight structure. The pipe body is straight, the surface is smooth, no corrosion pit is formed, the ceramic coating and the pipe body can be tightly attached conveniently, the attaching tightness is ensured, and the surface is prevented from falling off.
The utility model discloses further improve, the high temperature resistant degree of external coating is 1500 ℃, and the coating evenly adheres to the body surface. The high temperature resistance of the outer coating can effectively protect the body of the oxygen lance from oxidation.
The utility model discloses the further improvement, the thickness of external coating is 0.5 0.1 mm.
The utility model discloses the further improvement, the surface of external coating still spouts aluminium.
The utility model discloses further improve, helicitic texture one end is equipped with the plastics block. The plastic cap can effectively protect the screw teeth of the thread structure and prevent the conditions of rusting, bruising and galling.
The utility model discloses further improve, the helicitic texture specification is R3/4 standard pipe thread.
The utility model has the advantages that: through carrying out the coating on the surface at the oxygen lance, paint ceramic coating in body outside and inside, can effectively reduce the oxidation problem of oxygen lance to simple structure easily operates, strengthens the life of oxygen lance, improves production efficiency, reduces the problem of wastrel.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the embodiment, as shown in fig. 1, the ceramic coating oxygen lance is characterized by comprising a lance body 1, wherein ceramic coatings are coated on the inner and outer surfaces of the lance body 1, the ceramic coatings are divided into an outer coating 2 and an inner coating 3, a threaded structure 4 is arranged at one end of the lance body 1, the threaded structure 4 is integrated with the lance body 1 and attached to the surface of the lance body 1, an uncoated layer 7 is arranged at one end of the lance body 1, and a certain distance is arranged between the uncoated layer 7 and the threaded structure 4.
In this embodiment, the overall structure of the pipe body 1 is a straight structure. The pipe body 1 is straight, the surface is smooth, no corrosion pit is formed, the ceramic coating and the pipe body can be tightly attached conveniently, the attaching tightness is guaranteed, and the surface is prevented from falling off.
In this embodiment, the high temperature resistant degree of the outer coating 2 is 1500 ℃, and the coating is uniformly attached to the surface of the pipe body. The high temperature resistance of the outer coating 2 can effectively protect the body of the lance against oxidation.
In this embodiment, the thickness of the overcoat layer 2 is 0.5 ± 0.1 mm.
In this embodiment, the surface of the outer coating 2 is further sprayed with an aluminum layer 5.
In this embodiment, a plastic cap 6 is disposed at one end of the thread structure 4. The plastic cap 6 can effectively protect the screw teeth of the thread structure and prevent the conditions of rusting, bruising and galling.
In this embodiment, the thread structure 4 has a specification of R3/4 standard pipe thread.
Not described much here. It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
