Abstract
The invention discloses heating method which can avoid decarbonization of high carbon billet or steel ingot. In the whole process of high carbon steel heating or preheating, heating, heat preservation period, it uses strong oxidizing gas to heat billet or steel ingot. The gas is controlled by air overplus coefficient, the coefficient (air and fuel, such as the ratio of coal gas, heavy oil) is 1.2-1.4.
