The light-hydrocarbon gas reverberatory furnace comprises a furnace body, wherein the furnace body is provided with a furnace hearth; a fixed cover and a gas burner are arranged on the furnace body; a furnace body bottom disc is arranged at the lower end of the furnace body; a molten iron discharging tank is arranged in the furnace hearth; a lifting movable furnace cover is arranged at the top end of the furnace body; a heat exchange device is arranged outside the furnace body and is connected with the furnace body throughthe lifting movable furnace cover; electric pushing rods are arranged on the sides of the furnace body; the heat exchange device is divided into an area I, an area II and an area III; the area III isarranged under the area I; the area II is arranged under the area III; tubular heat exchangers are arranged in the area II and the area III; a smoke discharging outlet is formed in the lower end of the heat exchange device; lifting electric pushing rods are arranged under the outer side of the heat exchange device. The invention aims to provide the light-hydrocarbon gas reverberatory furnace whichis characterized in that the structure is miniaturized, the furnace temperature is greatly increased, the energy consumption is low, the light-hydrocarbon gas reverberatory furnace is pollution-free,and the discharged smoke reaches the standard.
Description
technical field [0001] The invention relates to the technical field of nonferrous smelting furnace equipment, in particular to a light hydrocarbon gas reverberatory furnace. Background technique [0002] The reverberatory furnace is an important equipment for melting cast iron in foundry production. It melts scrap steel and iron blocks and pours them into sand molds. After cooling, the castings are obtained by opening the box. Used in the production of castings and steel castings. [0003] At present, the hourly output and tonnage of traditional coke-free natural gas cupolas and pure oxygen rotary furnaces are relatively large, which makes many foundry enterprises switch to multiple induction heating furnaces for casting production. At present, casting production consumes a lot of energy, and the melting cost of electric energy consumption is high. , causing serious pollution to the environment. [0004] The Chinese patent application number is 201420284555.9, application ...
