The roller body is made of CrMnN, the enlarged cooling cavity and the inner hole arc groove are formed in the roller body, so that the strength of the outer wall of the roller body and the fatigue resistance strength of the surface of the roller body can be ensured, and the shaft cover is welded between the shaft and the roller body in a special welding mode, so that the requirements of bearing certain strength, water pressure resistance and the like are met; meanwhile, a plurality of inner hole arc grooves are formed in the inner wall of the cooling cavity and matched with the descaling ball assembly, so that scale and air plugs or air films on the inner wall of the roller body can be broken, water and the inner wall can flow well, and the cooling effect is improved.
Description
The technical field is as follows:
the utility model relates to a metallurgical steel rolling equipment field, in particular to novel continuous casting billet bearing roller.
Background art:
the structure of the prior continuous casting blank carrier roller generally adopts a cooling mode with a spiral groove inside, the suspended matters of cooling water used on site are more, and a lot of water scale can be adsorbed on the inner wall of the carrier roller after long-time use, so that the cooling relation between the cooling water and the inner wall of the carrier roller is blocked; the surface of the roller body is in a working environment of about 1200 ℃ for a long time, and the heat transfer of the red blank ensures that the inner wall of the roller body has certain temperature to form an air plug or an air film. The scale in the spiral groove can not be cleaned, the internal control can not generate air blockage or the air film can not be eliminated, so that the cooling effect is greatly reduced, the temperature of the roller body is overhigh, the outer surface is cracked, the surface of the red blank is scratched, and the product quality is influenced.
It is therefore envisaged to provide a novel continuous casting billet support roller to solve the problems of the prior art.
The surface of the roller body of the carrier roller is in a high temperature of 1200 ℃ for a long time, and the roller body of the carrier roller must have certain high temperature resistance and wear resistance, if the materials are not right, the upper surface can crack during working, and scratch is caused on the surface of a red blank, so the roller body is made of CrMnN materials, and an enlarged cooling cavity and a plurality of inner hole arc grooves are arranged inside the roller body, so that the strength of the outer wall of the roller body and the fatigue resistance of the surface are ensured.
The shaft cover is a structure designed for ensuring the function of the internal structure of the roller body, the casting cannot meet the requirement, the roller body is made of CrMnN material, the shaft cover material is selected to be Q235 for ensuring the welding performance of the roller body, the welding rod is made of stainless steel, the heating assembly welding is carried out, the process requirement of tempering treatment is carried out, and the related technical requirements such as certain strength, water pressure resistance and the like are met.
The descaling ball has the function that when the roller body main body operates, the descaling ball always runs synchronously below the inner part of the roller body, so that scale and air blockage or air film on the inner wall of the roller body are removed in real time, water and the inner wall have good flow, and the cooling effect is improved.
The utility model has the following contents:
the utility model aims at improving and innovating the shortcoming and the problem that exist among the background art, provide a novel continuous casting billet bearing roller.
The utility model adopts the technical proposal that:
a novel continuous casting billet roller comprises a roller body: the roller body middle part has the cooling cavity, and the pivot has been passed in the air cooling cavity, the axle cap is installed with the roller body junction to the pivot, and the stainless steel welding rod welding is adopted with the roller body junction to the axle cap, is equipped with a plurality of hole circular arc grooves on the cooling cavity inner wall at roller body middle part, install the scale removal ball subassembly in the hole circular arc groove, the scale removal ball subassembly has the axis body, and it has a plurality of scale removal balls to follow length direction evenly distributed on the axis body.
The roller body is made of CrMnN materials, and an internal cooling cavity is enlarged.
The shaft cover is made of Q235 materials, a stainless steel welding rod is selected for a welding position, and the processes of heating assembly welding and tempering treatment are adopted.
The radius of the inner hole arc groove is matched with the descaling ball assembly.
The descaling ball assembly is matched with the inner hole arc groove, and is influenced by self weight when the roller body rotates, and rotates synchronously below the inner part of the roller body.
Compared with the prior art, the utility model has the advantages of:
the roller body is made of CrMnN material, the enlarged cooling cavity and the plurality of inner hole arc grooves are formed in the roller body, the strength of the outer wall of the roller body and the strength of surface fatigue resistance can be ensured, and the shaft cover is welded between the shaft and the roller body in a special welding mode, so that the requirements of bearing certain strength, resisting water pressure and other related technologies are met; meanwhile, a plurality of inner hole arc grooves are formed in the inner wall of the cooling cavity and matched with the descaling ball assembly, so that scale and air plugs or air films on the inner wall of the roller body can be broken, water and the inner wall can flow well, and the cooling effect is improved.
