Plate blank movement simulation method for roller hearth type heating furnace

Abstract

The invention discloses a roller hearth type heating furnace plate blank movement simulation method, which comprises the following steps of: firstly, establishing a three-dimensional simulation modelof a furnace body, a conveying roller and a plate blank, then dividing a movement region and a static region in a furnace, and finally, carrying out simulation solution through fluid simulation software. Compared with the traditional experiment test; according to the method, the movement condition of the plate blank in the furnace can be predicted only through computer simulation; the experiment period can be shortened; the test cost is saved; meanwhile, the temperature change process of the whole plate blank in the movement process of the plate blank is simulated; the heating furnace is different from a static blank heating furnace and a stepping heating furnace; due to the fact that the temperature difference of the bottom of the plate blank in the heating process is small and is closerto the heating conditions of various plate blanks in the actual production process, the temperature change cloud chart generated through the method can be applied to actual production, production parameters can be designed, and then the product quality is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of computational fluid dynamics, and relates to a method for slab motion simulation of a roller hearth heating furnace. 【Background technique】 [0002] Roller hearth heating furnace is an important equipment in the heat treatment process of steel plate. Due to the small contact area and short contact time between the steel plate and the roller during the movement in the roller hearth heating furnace, the temperature difference at the bottom of the steel plate during the heating process is small. It is difficult to manually measure the temperature of the slab in the furnace during its movement. Fluid computational dynamics can simulate the movement of the slab on the rollers in the furnace to overcome the high cost, long cycle, and limited environment of the existing technology. factor. [0003] Through the research and analysis of the numerical simulation of heating furnaces at home and abroad, it is bas...
