Metal strengthening heat transmission protection method in metal workpiece heating techniqiue

Abstract

The invention relates to a method for protecting metal and intensifying heat diffusion in the technology for heating metal objects, the technology for heating metal materials or workpieces comprises a heating furnace and a rolling line, wherein a paint spraying system is additionally arranged in front of the heating furnace, and the process of the technology comprises: firstly, coating paint on metal billets or the workpieces, secondly, heating the metal billets or the workpieces in the furnace, thirdly, taking the metal billets or the workpieces out of the furnace, fourthly, removing a coating layer of the metal billets or the workpieces, and fifthly enabling the metal billets or the workpieces to enter into the rolling line. The method is a new method, namely, the workpieces are put on coat and then heated, which plays the role of protecting the metal and intensifying the heat diffusion. According to the method of the invention, heated metal workpieces is coated with functional paint on the surface and then heated, which has the advantages that the metal oxidization ratio is lowered, the trace element loss rate in the metal is lowered, the heating speed is increased, the existing heating equipment output and the production rate are increased, and the like.

Description

technical field [0001] The present invention relates to a metal material or workpiece heating process, in particular to a metal object heating process such as the heating process after metal casting billets before thermal processing, after metal casting billets are cut and segmented, and before entering the furnace, especially a metal material or workpiece A method of protecting metals during heating processes to enhance heat transfer. Background technique [0002] Metal materials or workpieces such as steel ingots, steel billets, steel plates and other metal objects need to be heated in industrial furnaces during the thermal processing process. At present, the method of putting the workpiece exposed into the industrial furnace for heating has the following two disadvantages: [0003] 1. Mass transfer occurs between the metal material and the gas in the furnace during the heating process. [0004] (a) A chemical reaction occurs between the metal and the oxygen in the furna...
