Mastering the heating equipment in the cold-rolling shop

In 1980-1981, the Institute of Ferrous Metallurgy and the Novolipetsk Metallurgical Plant conducted a joint study to determine the basic operating conditions for heating equipment at the plant and to compare these conditions with the specifications. The study results showed that the furnaces begin to be regulated by the zone thermocouples 1-1.5 h after the beginning of heating, regardless of the size of the charge. This is because the furnaces were lined with high-alumina ShVP-350 slabs, with excellent heat-insulating properties. They were the first furnaces in domestic practice to be equipped with this material.
