Abstract


Fused cast AZS material widely used in glass preparation industry is a very important class of refractory materials. However, defects can easily crack during the cooling in the casting production process, resulting in yield, high production costs. For this problem, the finite element method, based on factory production AZS33 the process of casting refractory bricks was simulated cooling process of Fused cast refractory bricks in the field of temperature and stress variation is proposed for reducing the heat stress the improvements, the main contents are:(1) By analyzing the heat transfer process during the cooling process, to establish a cast refractory cooling of the temperature field model, using transient analysis to simulate the solidification process of refractory and found it completely solidified time is about 11h.(2) Using thermal-mechanical analysis, to simulate the solidification process of refractory heat stress. For the special nature of the solidification process, a dynamic solidification boundary approach to solve dynamic solidification process the difficult problem of boundary treatment.(3) By analyzing the thermal stress curve of each feature point, found for promoting the thermal conductivity of refractory bricks can reduce the thermal stress.(4) Based on the analysis in the stress field, using the method of replace insulation material, by analyzing the impact of insulation materials to minimize the thermal stress of the refractory brick, obtained by comparison and induction: Should be comprehensive selection of density, specific heat, thermal conductivity, relatively high thermal insulation material, for fast relief thermal stress more effective.This study established AZS33 refractory finite element model during the cooling process, due to the solidification process taking into account the structural changes in boundary conditions, and the actual situation is closer, by the results of stress calculation and the actual product comparison, the model obtained is quite reasonable, come to some certain conclusions of The product quality improvements, and provides the reference of the research methods to follow-up study.
