The invention relates to a novel iron casting hot air smelting furnace, which comprises a furnace cylinder, a furnace body, a furnace top and a blower, wherein the furnace cylinder is provided with a slag hole and a tap hole; a first ventilation opening is formed in the lower end of the furnace body; the connecting relation is that the furnace top, the furnace body and the furnace cylinder are connected integrally from top to bottom; and the blower is used for supplying air to the furnace body through the first ventilation opening. The novel iron casting hot air smelting furnace is characterized in that the middle upper part of the furnace body is provided with a second ventilation hole; and the blower is used for supplying air into the furnace body through the second ventilation hole at the same time. The novel iron casting hot air smelting furnace has the advantages of low furnace body, high heat utilization ratio and low pollution.
Description
technical field [0001] The invention relates to a cast iron hot-blast smelting furnace using coke as fuel, in particular to a novel cast iron hot-blast smelting furnace which effectively utilizes the heat generated in the furnace body. Background technique [0002] The hot air smelting furnace for cast iron supplies the air required for combustion into the furnace body through a blower, so that the cast iron is smelted by combustion. When it is necessary to increase the effective temperature in the furnace shaft, the technical means adopted now are to increase the height of the furnace shaft and prolong the preheating time, but such setting has low heat utilization rate and unstable quality of molten iron. [0003] In addition, the waste generated by the hot blast smelting furnace is also relatively serious for air pollution. Contents of the invention [0004] The invention aims at proposing a novel cast iron hot blast smelting furnace with a relatively low furnace body, ...
