Aluminum-based plated material, method for producing the same, and apparatus for producing aluminum-based plated material

Abstract

This invention discloses an aluminum-based coated blank, its preparation method, and an apparatus for preparing the aluminum-based coated blank. In one specific embodiment, the aluminum-based coated blank includes a joint connecting two or more aluminum-based coated steel plates. The aluminum-based coated steel plates include: a base steel plate comprising the following components by weight percentage: carbon (C): 0.01 wt% to 0.5 wt%; silicon (Si): 0.01 wt% to 1.0 wt%; manganese (Mn): 0.5 wt% to 3.0 wt%; phosphorus (P): greater than 0 wt% and less than or equal to 0.05 wt%; sulfur (S): greater than 0 wt% and less than or equal to 0.01 wt%; aluminum (Al): greater than 0 wt% and less than or equal to 0.1 wt%; nitrogen (N): greater than 0 wt% and less than or equal to 0.001 wt%; the balance being iron (Fe) and other unavoidable impurities; and a coating, which is 20 g / m 2 Up to 100g / m 2 The amount of adhesion is formed on at least one side of the base steel plate and includes aluminum (Al).
