INTRODUCTION OF CONTINUOUSLY CAST METAL INTO COMMERCIAL PRODUCTION OF BOILER TUBES AT JSC VOLZHSKY TUBE PLANT

摘要

Feasibility of usage of continuously cast ingots produced by JSC Volzhsky Tube Plant instead of conventional deformed tube stock for the production of boiler tubes which are used in boilers of wide power range was determ ined in the present work for the first time in the CIS tube industry. The State Tube Institute (DTI) developed and introduced at JSC Volzhsky Tube Plant the technology of boiler tube production according to Specifications 14-3-460-75 if steel grade 20 directly from continuously cast ingots produced by JSC Volzhsky Tube Plant. Specifications and technical manuals for commercial supply of hot rolled boiler tube stocks produced at Krasny Oktyabr Plant from continuously cast blooms made by JSC Volzhsky TUBE plant; continuously cast round ingots intended for boiler tubes produced by JSC Volzhsky Tube Plant; boiler tubes produced by JSC Volzhsky Tube Plant from continuously cast ingots were developed and brought into effect.
