Abstract

The invention relates to a friction wear simulation experiment machine of a continuous casting crystallizer. According to the invention, a driving-disc (1) of the experiment machine is connected with a servo motor through a coupler, a position regulating block (2) on the driving disc (1) is hinged to a slide block (17) at one end of a connecting rod (3), the other end of the connecting rod (3) is connected with a continuous casting crystallizer sample (5) through a hinge, the continuous casting crystallizer sample (5) and a reciprocating slide block (4) are fixed through a pin and perform reciprocating motion along a guide rail (6), so that relative sliding of the continuous casting crystallizer sample (5) and billet is realized. The temperature of the billet is adjusted by a temperature-control system, the load is applied to the continuous casting crystallizer sample (5) by a hydraulic loading system (16), a vacuum system (12) provides vacuum environment for the experiment machine in the invention, and relative experiment is carried out under vacuum condition. The experiment machine can evaluate the friction wearing performance of the continuous casting crystallizer under practical condition, and the usage life is predicted. The experiment machine has the advantages of simple structure and convenient operation, and has high application value.

Description

technical field [0001] The invention belongs to the technical field of metallurgical continuous casting, and in particular relates to a friction and wear simulation test machine for a continuous casting crystallizer. Background technique [0002] In the field of metallurgical continuous casting technology, the mold is a very important part of the continuous casting machine, known as the "heart" of the continuous casting equipment, and is the basis for ensuring the stable operation and efficient production of the continuous casting machine. A mold with excellent performance can improve billet quality and production efficiency, and prevent defects such as cracks and breakouts. Among them, the friction and wear performance is one of the important factors that determine the performance of the mold. Improving the friction and wear performance of the continuous casting mold has always been a continuous Research focus of casting technology. Mold surface coating is a commonly used ...

Problems solved by technology

Mold surface coating is a commonly used method to improve the friction and wear performance of the mold. However, there is currently a lack of experimental equipment to reasonably evaluate the friction and wear performance of the continuous casting mold coating. This is because the actual working conditions of the mold in the continuous casting process Complex and extremely harsh, the inner wall of the crystallizer not only bears the pressure and friction from the billet, but also is affected by high temperature and mold slag

The conventional friction and wear testing machine is difficult to simulate the actual working conditions of the mold, so it is impossible to reasonably evaluate the friction and wear performance of the continuous casting mold, which seriously restricts the optimization of the coating process of the mold and its practical application in continuous casting technology
