A heavy oil injection control apparatus for temperature management of furnace bottom is provided to connect injection holes and a heavy oil pump by a hose and to form an injection line using an automatic valve for expanding a work space and lengthening life time of the furnace. A heavy oil injection control apparatus for temperature management of furnace bottom comprises a heavy oil injection hole(50), a small branch pipe valve(60), a plurality of branch pipe valves(70), and a heavy oil injection unit(80). The heavy oil injection hole is extended through a body steel shell(30) of a furnace(10), and formed between the body steel shell and a brick(20). The small branch pipe valve, connected to the heavy oil injection hole, is opened and closed so that the heavy oil flows into a cavity. The heavy oil injection unit is connected to each of the branch pipe valves. The heavy oil injection unit includes a heavy oil tank(82), a discharge main valve(83), a heavy oil injection pump(86) connected to a pressure gauge(84) and a flow meter(85), and a drain valve(87).
