Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0037] The installation between the sleeve of the short-mandrel continuous casting roll and the mandrel that needs to be installed in the present invention is an interference fit, and the interference is between 0.41 and 0.45mm, so the installation should be realized by using the principle of thermal expansion and contraction of materials Assembling, each step of assembly adopts vertical installation.

[0038] The structure of the short mandrel continuous casting roll is as follows: figure 2 As shown, it includes the first roll cover 1, the second roll cover 2, the third roll cover 3, the first mandrel 4, the second mandrel 5, the third mandrel 6, the fourth mandrel 7, the first water guide Cover 8, the second water guide sleeve 9, the first set of bearing assemblies, the second set of...

Abstract

The invention provides an installation method for short mandrel continuous casting rolls adopting interference fit. Since the installation between roller sleeves and mandrels of the short mandrel continuous casting rolls adopts interference fit, the assembly is realized by utilizing the principle of thermal expansion and cold contraction of materials, namely the roller sleeves are assembled with the mandrels at normal temperature after being heated to a set temperature, or the roller sleeves are assembled with the cooled mandrels after being heated to the set temperature, so that the requirement on interference fit of the short mandrel continuous casting rolls can be realized. The installation method is suitable for installation of the short mandrel continuous casting rolls.

Description

technical field [0001] The invention relates to the processing of continuous casting rolls, in particular to a method for installing continuous casting rolls with interference fit short mandrels. Background technique [0002] The continuous casting roll is the key part of the bending section, the arc section, the straightening section and the horizontal section of the continuous casting machine. The life of the continuous casting machine depends on the service life of the continuous casting roll, and the assembly method of the continuous casting roll is the key factor affecting its service life. [0003] Usually, the fit between the roll sleeve and the mandrel of the long-mandrel type continuous casting roll is a gap fit, and the connection is made with a key. Side roller sleeves and end bearing housings and bearings and other accessories. [0004] The structure of the long mandrel type continuous casting roll is as follows: figure 1 As shown, the long mandrel type contin...
