Abstract

PURPOSE:To effectively prevent the local deformation of a thin strip by scanning an electron beam along the edge of a square with one side parallel to the cross direction of the strip and longer than the width of the strip. CONSTITUTION:A long-sized thin strip such as a steel sheet is continuously dry-plated with TiN, etc. The electron beam is scanned along the square with one side parallel to the cross direction of a band steel 1 and longer than the width of the steel by using an electromagnetic deflecting coil in the preheating of the band steel 1. Namely, the steel is gradually heated at two zones a1 and a2 in the traveling direction by one electron-beam device. The scanning in the traveling direction is carried out on a graphite plate 2, and the electron beam is absorbed by the plate 2 to prevent the overheating of the band steel 1. As a result, the steel can be effectively preheated without being deformed, the steel surface is cleaned, and the adhesion of a coating film is improved.
