HEATING CONTROL METHOD OF MAGNESIUM ALLOY STOCK, AND HEATING FURNACE

摘要

PROBLEM TO BE SOLVED: To prevent the combustion of a magnesium alloy stock charged in a heating furnace caused by the ignition when the temperature in the furnace reaches an abnormal temperature exceeding the target value. SOLUTION: When the temperature in the heating furnace reaches the temperature T1 higher than the preset target temperature T0, the heating of the heating furnace is stopped, and when the temperature in the heating furnace reaches the preset temperature T2 which is higher than the temperature T1 and lower than the ignition point of the alloy after the heating is stopped, the inert gas is injected in the heating furnace.
