Abstract

The invention discloses anANSYS-based multi-field coupling stress distribution simulation method for a high-temperature carbonization furnace and relates to the technical field of design analysis methods of high-temperature carbonization furnaces. The technical problem that the stress characteristics of different furnace chamber materials cannot be tested in the design stage of a high-temperaturecarbonization furnace in the prior art is solved. According to the adopted scheme, the method comprises the steps that establishing three-dimensional simulation model, respectively transmitting the fluid calculation domain and the structure calculation domain to a Blocking module of ICEM software and Mesh software to carry out mesh generation; setting in a FLUENT module of ANSYS software; transmitting data to ANSYS software; importing a temperature distribution result in an Imported Load option to obtain a temperature distribution result; carrying out simulation operation in the Solution option to obtain stress distribution characteristics of the muffle structure at different temperatures; under the same setting condition, judging the stress distribution state of the high-temperature carbonization furnace at different temperatures and airflow velocities by setting different working temperatures and airflow velocities to repeatedly carry out simulation calculation for multiple times, sothat the structural performance of the furnace chamber can be better predicted, and the basis for designing the muffle chamber structure and operation process parameters of the high-temperature carbonization furnace is provided.

Description

technical field [0001] The invention relates to the technical field of design and analysis methods for high-temperature carbonization furnaces. Background technique [0002] Carbon fiber production is a high-energy-consuming industry. The high-temperature carbonization furnace is one of the largest energy-consuming households in carbon fiber production equipment. At the same time, the high-temperature carbonization furnace is also a key equipment for carbon fiber production. The carbonization furnace is mainly used for high-temperature carbonization of pre-oxidized wire to convert it into carbon fiber with a carbon content greater than 90%. The carbonization temperature of T300 carbon fiber is about 1350°C-1450°C, and that of T800 carbon fiber is about 1400°C-1600°C. The carbonization temperature needs to be further increased to produce higher strength carbon fiber. Among them, the furnace cavity is the key component of the high-temperature carbonization furnace. It works i...
