Embodiment 1

[0019] 1. Replace the end cover (original) with an end cover 8 with a keyway. The size of the end cover 8 with a keyway is φ160*15mm, and the installation space for the cross slider 7 is reserved during installation. On the premise that the position of the bearing seat remains unchanged, the end cover 8 with the keyway can reserve the installation space for the cross slide 7 on the basis of meeting the strength and positioning requirements, which solves the problem of the application of the cross slide 7 mechanism and the two subsections. Space issues for roll connections.

[0020] 2. Set the cross slider 7 in the reserved installation space. The thickness of the cross slider 7 is 12mm; there is a key on the cross slider 7, the key height is 10mm, and the key width is 20mm; The hole size is φ54, and the outer circle size is φ144. The thickness dimension of the cross slider 7 is designed by utilizing the feature of the allowable micro axial displacement of the cross slider 7 ....

Abstract

A method utilizing a crosshead shoe to reconstitute a roller system of a continuous casting machine segment belongs to the technical field of continuous casting equipment. According to the method, the dimension and structure of the crosshead shoe are continuously improved, the crosshead shoe is matched and assembled with a lip-type packing to be used, so the water leakage problem of an intermediate water jacket of the roller system is improved, the root cause for the water leakage problem of the roller system is identified, the water leakage amount is reduced, the influence of water leakage to the casting blank quality is decreased, and the service life of a segment is improved; and the promotion of the technology has better social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of continuous casting equipment. In particular, it relates to a method for transforming a roll system of a sector section of a continuous casting machine by using a cross slide block. Background technique [0002] At present, the connection form of the fan-shaped roller system in some domestic steel mills is generally the same, all of which are in the form of two-section or three-section rollers. The connection is made through the intermediate water connection sleeve, and the O-ring is used for sealing. The rotary joint uses a built-in rotary joint. Use light compression techniques. In the actual production process of the roll system of this type of structure, water leakage is prone to occur at the intermediate water connection sleeve, which affects the life of the roll system and the quality of the slab. There is no good way to completely solve this problem. [0003] The 2# continuous casting machine of a...
