Heating parameter setting method capable of clearly considering structure target requirements

Abstract

The invention discloses a heating parameter setting method capable of clearly considering structure target requirements. The heating parameter setting method capable of clearly considering the structure target requirements comprises the following steps that firstly an empty burning sample is obtained by aiming at a target steel grade, the lower limits of heating temperature and heating time are obtained by combining the austenite structure grain sizes of the empty burning sample in austenite structure grain pictures, and the heating temperature and the heating time are further restrained by taking the dissolution condition of inclusions as a standard, so that the reasonable heating time of the target steel grade is obtained; and a reasonable heating process is formulated according to the requirement of a material, the structure change of the material in the heating process is accurately controlled, the reasonability of the heated blank structure is guaranteed, and resource utilizationis maximized. According to the method, the dissolution condition of the inclusions in the material along with the heating temperature and the heat preservation time can be obtained according to the size change of the inclusions at different times, a reasonable heating process can be formulated according to the field condition requirements, and resource utilization is maximized.

Description

【Technical field】 [0001] The invention belongs to the technical field of material processing, and in particular relates to a method for formulating heating parameters that clearly considers organizational target requirements. 【Background technique】 [0002] At present, in the steel mills, the formulation of the heating process in the thermal processing of materials is generally based on empirical formulas to calculate the heating time, and the determination of the heating temperature is generally determined according to the dissolution temperature of the alloy elements of the steel type. This method has great disadvantages Defective. When the type and content of alloying elements in the material change, its solution temperature and solution time will change accordingly. The heating process formulated only by empirical formulas cannot accurately predict the uniformity of the grain size after heating. Understanding the evolution of material structure with process parameters a...
