Processing method of continuous casting machine bearing block

Abstract

The invention relates to a processing method of a continuous casting machine bearing block. The processing method of the continuous casting machine bearing block includes that blank rough milling, rough inner hole turning, water cooling tank milling and water hole drilling are sequentially performed on a bearing block body, a water tank and a waterhole burr are removed, the bearing block body is sent in a high temperature furnace to be heated for four hours, the bearing block body is kept at the temperature of 120-150 DEG C, and finally the bearing block body enters a welding process. The welding process includes that a stainless steel cover plate is sealed and welded by adopting handmade argon arc welding, then the temperature is kept, a front plane and a rear plane of the bearing block body are ground on a grinding machine accurately to a drawing paper size, the bottom surface of the bearing block body is ground by using a rear plane of a clamp as a reference, perpendicularity of the front plane, and the rear plane and the bottom surface is controlled within a range of +-0.05mm; a key groove on the bottom surface is processed by adopting a line cutting processing method, then the key groove on the bottom surface is used as a reference, central height and symmetry are controlled by the clamp, and allowance is reserved after semi-finished turning; and finally finish turning is performed on an inner hole of the bearing block body until the inner hole of the bearing block body reach a drawing paper size.

Description

[0001] This application is a divisional application. The application number of the original application is: 201110065201.6, the application date: 2011-3-18, and the name of the invention: "Processing method of continuous casting machine bearing seat". technical field [0002] The invention relates to the technical field of a processing method for a bearing seat, in particular to a processing method for a bearing seat of a water-cooled continuous casting machine. Background technique [0003] The production process of continuously casting high-temperature molten steel into a billet with a certain cross-sectional shape and a certain size specification is called continuous steel casting. [0004] The equipment required to complete this process is called continuous casting equipment. The electromechanical and hydraulic integration of steel pouring equipment, continuous casting machine body equipment, cutting area equipment, dummy bar collection and conveying equipment constitute...

AI Technical Summary

Problems solved by technology

[0005] The surface temperature of the continuous casting machine is high when it is working, and the ordinary bearing seat cannot be used

Water-cooled bearing housings must be used. The existing continuous casting machine bearing housings are more complex in manufacturing process and have a shorter service life, resulting in higher production and maintenance costs
