A simple mathematical method is established based on the principles of mass and energy balance, thermodynamics and the kinetics of the oxidation rates to estimate the temperature change of the melt bath during the oxygen blow in BOF (LD converter). An approach was used based on a hypothetical assumption, which is no scrap added to the reactor, as a first step. The mount of scrap could be added at the beginning of the operation, which is calculated from static mass and energy balances, is used in combination with the hypothetical temperature change during the oxygen blown, which is calculated from the dynamic mass and energy balances, to calculate the temperature change during the oxygen blowing time. It is found that the amount of scrap could be added is 230kg/ ton hot metal, while the hypothetical temperature of the melt bath reaches 1830{u00B0}C by the end of the blow. The final temperature change of the melt bath is then compared to another which is measured based on full scale experimental work{u2003}
