Description

連續塗佈裝置 Continuous coating device

本發明是有關於一種利用施膠輥將塗佈液連續塗佈至經由通板開口部而沿鉛垂向上方向運送的鋼板的表面上的連續塗佈裝置。 The present invention relates to a continuous coating device that uses a sizing roller to continuously apply a coating liquid to the surface of a steel sheet conveyed in a vertical upward direction through a plate opening portion.

在現有的連續塗佈裝置中，是藉由在施膠輥的主體長度方向兩側端部的下方設置屋頂型的飛散塗佈液捕捉板，利用飛散塗佈液捕捉板將因穿過熔接點時的快速打開(quick open)而產生的飛散塗佈液回收至塗佈機盤(coater pan)，來抑制因飛散塗佈液而在鋼板上產生表面缺陷。 In the conventional continuous coating device, a roof-type scattering coating liquid catching plate is installed below the both ends of the main body of the sizing roller in the longitudinal direction, and the scattering coating liquid catching plate is used to pass through the welding point. The scattered coating liquid generated by the quick open at this time is recovered to a coater pan to suppress surface defects on the steel sheet due to the scattered coating liquid.
