Embodiment Construction

[0036] The present invention will be further described in detail below with reference to the accompanying drawings, which is an explanation rather than a limitation of the present invention.

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

[0038] The structure of the short mandrel continuous casting roll is as figure 2 As shown, including the first roller sleeve 1, the second roller sleeve 2, the third roller sleeve 3, the first mandrel 4, the second mandrel 5, the third mandrel 6, the fourth mandrel 7, the first water guide The sleeve 8, the second water guide sleeve 9, the first set of bearing assembly, the second set of beari...

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 an installation method of an interference assembly short mandrel continuous casting roll. Background technique [0002] The continuous casting roll is the key component of the bending section, arc section, straightening section and horizontal section of the continuous casting machine. The continuous casting roll supports the feeding and drawing of the starter bar, and supports and squeezes the billet during the drawing process. The role of pressing and straightening, the life of the continuous casting machine depends on the length of the life of the continuous casting roll, the assembly method of the continuous casting roll is the key factor affecting its life. [0003] Generally, the fit between the sleeve and the mandrel of the long mandrel continuous casting roll is a clearance fit, and the key is used for connection. The middle sleeve and the bearing seats and bearings o...
