Title:
アルミニウムシリコンを鋼板表面内に拡散する技術
Document Type and Number:
Japanese Patent JP6583638
Kind Code:
B2
Abstract:
The invention relates to a device and to a method to diffuse Al—Si into a surface of an Al—Si-coated steel sheet. First of all, a steel sheet is fed into a furnace that can be heated up to the diffusion temperature and subsequently, it is conveyed contactlessly through the furnace that has been heated up to the diffusion temperature. In this process, the steel sheet is heated up to the diffusion temperature, whereby the Al—Si diffuses into a surface of the steel sheet. Subsequently, the steel sheet with the Al—Si that has diffused into a surface is cooled off at a rate of less than approximately 25K/sec.
