Uniform-cooling cooling roller device and method for amorphous strip preparing

Abstract

The invention provides a uniform-cooling cooling roller device for amorphous strip preparing. The device comprises a supporting shaft, a roller core and a roller sleeve. The roller core is connected to the circumferential outer side of the supporting shaft in a sleeving manner, and the roller core is driven through rotation of the supporting shaft to rotate. The roller sleeve is connected to the circumferential outer side of the roller core in a sleeving manner, and the roller sleeve is driven by rotation of the roller core to rotate. A first cooling liquid channel and a second cooling liquid channel are formed between the outer side face of the roller core and the inner side face of the roller sleeve. The flowing direction of cooling liquid in the first cooling liquid channel is opposite to the flowing direction of cooling liquid in the second cooling liquid channel. First liquid inlet holes of the first cooling liquid channel and second liquid outlet holes of the second cooling liquid channel are all located in one side of the roller core in the radial direction, and first liquid outlet holes of the first cooling liquid channel and second liquid inlet holes of the second cooling liquid channel are all located in the other side of the roller core in the radial direction. The invention further provides a uniform-cooling method for a cooling roller for amorphous strip preparing. By means of the above scheme, the temperature field of the inner surface of the roller sleeve is made to be uniform, and therefore the effect of uniformly cooling the roller sleeve is achieved.

Description

technical field [0001] The invention belongs to the technical field of preparation of amorphous strips, and in particular relates to a uniform cooling cooling roll device and method for preparation of amorphous strips, which is mainly applicable to the uniform cooling of strips during the forming process of amorphous strips , especially suitable for the preparation process of amorphous broadband. Background technique [0002] The preparation process of amorphous strip is mainly the process of pouring molten steel onto a rotating water-cooled roll to rapidly solidify molten steel to form an amorphous strip. The structure of the existing water-cooled roll is mainly that the outer layer has a layer of roll sleeve 1, and the middle is a roll core 2, that is, a water storage chamber. The inside of the roll core is equipped with a support shaft 3, and the support shaft 3 is fixed in the bearing 30. The support shaft 3 has two functions, one is to drive the roller core 2 and the r...

Problems solved by technology

Such a circulating water path makes the temperature of the water inlet hole of the roll sleeve lower than that of the water outlet hole of the roll sleeve, which makes the temperature field on the surface of the roll sleeve uneven, resulting in different temperatures at both ends of the amorphous strip during the forming process, resulting in poor performance at both ends of the strip. difference
