METHOD OF DECARBURIZING ANNEALING OF COLD-ROLLED LOW-CARBON STEEL

摘要

Application: production of cold-rolled sheet steel with a low carbon content, intended for enameling. SUMMARY OF THE INVENTION: steel is heated in a gas atmosphere before annealing temperatures in three stages: first, 500 & amp; deg; C at 15-25 & amp; deg; C / s, then to Tn temperature defined by the ratio Tn (920-3 to 103% C) ± 20 & amp; deg; C, where C - initial carbon content at the speed of 5-10 & amp; deg; C / s, more arbitrarily. After soaking at an annealing temperature of steel is cooled. Table 1.
