Problems solved by technology

But for this kind of seriously damaged roller surface, these two maintenance methods will take a long time (even months) to barely repair the roller surface, which is unacceptable to the manufacturer, so it is often replaced after simple maintenance. Continued use will result in larger damaged areas and deeper pits, and the roller must be replaced or production stopped. This will cause great losses to the user and the manufacturer, and the service life of the roller surface will not meet the requirements. cause contract disputes

Abstract

The invention discloses an online recovery method for the roller face of a rolling machine. The online recovery method comprises the following steps that S1, a plurality of prefabricated wear-resistant blocks are manufactured; S2, the prefabricated wear-resistant blocks are welded to a roller face damaged area sequentially to form a plurality of mounting weld joints; S3, wear-resistant structuresare arranged on the surfaces of the prefabricated wear-resistant blocks; S4, the adjacent prefabricated wear-resistant blocks are connected in a welded mode to form connection weld joints; S5, the prefabricated wear-resistant blocks are connected with a normal roller face in a welded mode to form transitional faces; and S6, the transitional faces are provided with transitional wear-resistant structures in the outward extension direction of the wear-resistant structures. Through structural arrangement of the prefabricated wear-resistant blocks, the online recovery method can be used for rapidlyrecovering not only severely-damaged roller faces but also generally-damaged roller faces so that the extrusion effect of the roller faces in the late period of use can be ensured and the service life of the roller faces can be prolonged.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to an online repair method for the roller surface of a roller press. Background technique [0002] Roller press (high-pressure roller mill) is a kind of equipment for medium and fine crushing of ore developed in the late 1980s. With the progress of wear-resistant materials, hydraulic technology and control technology, in the last fifteen years It has been developed rapidly. Due to its large output, high efficiency, energy saving, environmental protection and other advantages, it has become an essential equipment in the field of mineral grinding production, and has been widely used in building materials, cement, metallurgical mines, chemicals and other industries. [0003] The roller press (high-pressure roller mill) is mainly composed of a roller system, a driving part, a hydraulic system, and a control system. The key component is the roller in the roller system. The rol...
