| 要旨 : 1983年6月，川崎製鉄㈱千葉製鉄所に完成した連続電気クロムめっき設備(TFLと略記)および同剪断設備は，その後順調に稼動している。TFLでは，逆電解法を用いためっき方式とICP分析装置を用いた自動溶液濃度管理システムとを開発し，またプロセスコンピュータによる操業条件の自動設定，入・出側作業の機械化・自動化によって全自動で高品質の製品を安定して生産している。剪断設備では，数値制御式シャー，高速ノーラッピングパイリングシステム，シャー入側のループレス化などによって，高速かつ高品質の剪断設備を実現した。 |
| Synopsis : The continuous tin-free steel line (TFL) and the shearing line were installed in June 1983 at the Cold Rolling Plant of Kawasaki Steel Corporation's Chiba Works and are now in smooth operation. They have the following characteristics: The adherence to paintings has been greatly improved by the development of the reverse electrolysis method. The automatic analysis system for measuring solution concentrations includes ICP analyzing equipment, which was also developed. Its optimum operating conditions are set by the process computer. Consequently, all chromium plated steel products are able to be manufactured by an automated process from entry to delivery. The new shearing equipment permits improvement in the accuracy of the cutting length by digital control systems developed. Equipment including no loop enhanced the accuracy of squareness and detection of surface defects of products. The piling process based on the high-speed no-lapping system prevents the sheets from the occurrence of slipping scratches. As a result, quality of the products has been improved and stabilized. |
