INTRODUCTION OF A LEVEL-2 AUTOMATED SYSTEM AS PART OF THE RECONSTRUCTION OF A WALKING-BEAM FURNACE IN THE RAIL-BEAM SHOP

摘要

Engineers and scientists in Russia and abroad are giving a considerable amount of attention to improving the quality of the rails being made by metallurgical plants. Rolling 100-m-long rails requires proper preheating of the continuous-cast semifinished products with a minimal temperature gradient along and across the products. A heating operation of the requisite quality is assured by the use of a level-2 automation system to heat the metal in the furnace.
