Abstract


This mold friction from the measured data analysis and simulation of mold oscillation state detection system establishment of two parts. Mold friction is to describe the crystallizer phenomena occurring complex thermodynamic behavior of the important parameters of quality defects and leakage of slab steel and other abnormalities are closely related. Therefore, the detection and analysis of friction , friction and obtain the relationship between the process parameters , which can be extracted to provide guidance for the production of useful information , to improve the quality of the slab , preferably protective slag to prevent leakage of steel and promote even cast efficient is extremely important significance. In the first part of this paper summarizes mold friction calculation methods and means of detection , based on the impact of mold friction factors are analyzed , discussed the protection of slag, slab width , pouring temperature , vibration frequency, negative strip time and negative slip rate on the effects of friction . Continuous casting mold oscillation technology is one of key technologies . With the continuous casting and near net efficient continuous casting technology, high casting speed of the slab defects and breakout accident and other issues stand out for slab continuous casting process control and quality put forward higher requirements. For mold oscillation state detection equipment operating conditions can grasp , understand the deviation and vibration vibration parameters related to and can determine transmission wear, orientation bias and other equipment failures. This second part of the design of the mold oscillation state detection simulation system , built using Visual C related hardware and data acquisition software is designed to achieve the right mold oscillation parameters on-line detection and identification, and real-time display relevant parameters , laboratory simulations acquisition results show that the system better to complete the data collection and parameter identification functions. In addition , based on the vibrational state of the hydraulic vibration means a calculation and test data analysis , the purpose is to explore the crystallization of the deviation between oscillation parameters , the parameters for the mold oscillation calculation and analysis provides a theoretical basis .
