Problems solved by technology

[0004] The inventor found in the research that the prior art for predicting the surface quality of the wire rod is based on the pickling method, that is, the surface quality of the wire rod is judged by removing the surface oxide scale by placing the wire rod in an acidic solution, and its defect is that its efficiency is low , depending on the concentration of the acid solution, it usually takes 5 to 15 minutes

Abstract

The invention relates to a method for quickly determining the surface quality of a wire rod. The method comprises the steps of 1 pulling and straightening the wire rod through a prefabricated roller way so as to quickly remove oxide scale on the surface of the wire rod; 2 observing the surface defect condition of the wire rod with the scale peeled off so as to pre-judge the surface quality of the wire rod; and 3 further confirming the surface quality of the wire rod based on a pickling method. Compared with the prior art of judging the surface quality of the wire rod completely depending on the pickling method, the method for quickly determining the surface quality of the wire rod can improve the working efficiency and save the working time.

Description

technical field [0001] The invention relates to the technical field of steel wire rod surface defect prediction, in particular to a method for rapidly determining the wire rod surface quality. Background technique [0002] Steel wire (rod) is an important type of product produced in the field of steelmaking. The production of wire rods is usually a process in which molten steel enters the casting equipment from the initial transfer equipment, is cooled and prepared into billets, and then prepared into wire rods with a square or circular cross-section. During the production process, the surface quality of the wire rod is often reduced due to the purity of the molten steel itself and the possible introduction of new impurities in the process. [0003] In the field of steel wire rod production, it is usually necessary to predict the surface quality of the wire rod, so as to determine whether the normal production of steel wire rod in large quantities is currently possible, or ...
