    • PURPOSE: A continuous heat treatment apparatus and method for stainless steel are provided to block an oxygen atmosphere of a heat treatment process from the strip by forming a coating layer on the surface of the strip in advance. CONSTITUTION: A continuous heat treatment apparatus for stainless steel comprises a coating unit(100), a heat treatment unit, and a coating removal unit. The coating unit forms a coating layer 100-200μm thick for preventing the formation of chromium oxide on the surface of strip(ST). The heat treatment unit is arranged consecutively to the coating unit and heat-treats the strip with the coating layer. The coating removal unit is arranged consecutively to the heat treatment unit and removes the coating layer from the strip. The heat treatment unit is an annealing furnace(110) for annealing the strip.
    • 目的:提供一种用于不锈钢的连续热处理装置和方法,用于通过在带的表面上预先形成涂层来阻挡来自带材的热处理工艺的氧气氛。 构成:用于不锈钢的连续热处理装置包括涂覆单元(100),热处理单元和涂层去除单元。 涂层单元形成100-200μm厚的涂层,以防止在带材表面(ST)形成氧化铬。 热处理单元与涂层单元连续布置,并用涂层进行热处理。 涂层去除单元被连续地布置到热处理单元上,并且从带剥离涂层。 热处理单元是退火炉的退火炉(110)。
