Problems solved by technology

Due to the lack of density, tension and oxidation resistance of the graphite roller sleeves used in the existing idlers, the flatness of the output steel strip is seriously affected, and at the same time, the aging speed of the idler sleeves is too fast, which greatly shortens the life of the roller sleeves. service life

Embodiment Construction

[0025] The first embodiment of the manufacturing method of the hollow graphite idler sleeve of the present invention includes the following steps:

[0026] a. Choose a commercially available cylindrical graphite blank, use a general lathe to pick up the outer circle of the cylindrical graphite blank according to actual needs, and then use a drill to hollow out the center of the cylindrical graphite blank.

[0027] b. Using commercially available industrial sodium silicate at room temperature, place the blank of the hollow graphite roller sleeve in the immersion tank for 3 hours, so that the hollow graphite roller sleeve is in the subsequent dipping step, and the dipping liquid is easier to adhere On the surface of the hollow graphite roller sleeve.

[0028] c. Fill the small holes and cracks on the hollow graphite roller sleeve blank after soaking with filler glue configured by weight: graphite 5, silica gel 1, aluminum dihydrogen phosphate 3, and repair the hollow graphite The id...

Abstract

The invention discloses a support roller sleeve manufacturing method, in particular to a hollow graphite support roller sleeve manufacturing method. The invention aims to manufacture a support roller sleeve which has long service life and improves the flatness of the steel belt. The hollow graphite support roller sleeve manufacturing method includes that the steps of impregnating in the impregnation fluid, spraying antioxidant on the surface of the hollow graphite support roller sleeve and the repeated polishing are added to the concrete implementation steps of the manufacturing method of the hollow graphite support roller sleeve; the surface flatness and the service life of the hollow graphite support roller sleeve are improved. The support roller sleeve manufacturing method is widely applicable to the continuous-casting and tandem-rolling production process of the steel strips or billets.

Description

Technical field [0001] The invention relates to a manufacturing method of an idler sleeve, in particular to a manufacturing method of a hollow graphite idler sleeve. technical background [0002] At present, in the steel rolling process, the conveyor is used to convey the rolled steel billet and the steel strip to realize the flow operation of cold or hot rolling, and is the main auxiliary equipment for rolling the steel strip. The idler roller is a necessary device on the conveyor, and the idler sleeve is an important component of the idler roller. Due to insufficient density, tension and oxidation resistance of the graphite roller sleeves used in the existing rollers, the flatness of the produced steel strip is seriously affected. At the same time, it also causes the roller sleeve itself to age too fast, which greatly shortens the length of the roller sleeve. Service life. Content of the invention [0003] The purpose of the present invention is to provide a method for manufac...
