Problems solved by technology
[0002] The casting and smelting industry has a lot of pollution, and cupolas emit serious pollutants, which have been strictly controlled by major provinces and cities; the use of intermediate frequency furnaces for smelting consumes a lot of energy, which is unbearable for most enterprises
Some centrifugal casting, investment casting, negative pressure and other precision casting enterprises adopt the mode of direct purchase of molten steel for production, which not only increases the production cost, but also limits the output of the enterprise and cannot meet the production demand

Embodiment
[0027] Example: The present invention is used to obtain a cast iron alloy melt at 1480°C.
[0028] see figure 1 , the main equipment in the cast iron smelting method in the figure includes a feeding crane 1, a feeding mechanism 2, a gas furnace 3, a feeding mechanism 4 and an intermediate frequency furnace 5.
[0029] see figure 2 , the gas furnace 3 mainly includes a furnace body 3-1, a burner 3-2 and a plurality of feeding cars; there are a plurality of feeding cars in the gas furnace 3, and its serial numbers are 3-C-1, 3-C-2, 3- C-3.....3-C-N.
[0030] The burners of the gas furnace 3 are arranged on the top of the furnace, and are heated by top blowing; the burners 3-2 are arranged on the top half of the furnace on the outlet side of the gas furnace, and the other half of the gas furnace 3 has no burners.
[0031] see image 3 , The furnace structure of the gas furnace is a stepped structure, and the height of the half of the furnace with burners is greater than 100m...

The invention discloses an energy-saving and environment-friendly casting and smelting production method. The energy-saving and environment-friendly casting and smelting production method comprises the process steps that to-be-smelted materials are sequentially and quantificationally added into a feeding mechanism in an automatic feeding or manual feeding mode; the to-be-smelted materials are added into a charging cart of a tunnel-type natural gas stove through the feeding mechanism; the charging cart is pushed into a hearth of the gas stove; the gas stove preheats the to-be-smelted materials to 850-1200 DEG C; and then a discharging mechanism quickly transfers the preheated to-be-smelted materials into an intermediate-frequency smelting furnace to be smelted, and a qualified alloy melt is obtained finally. By adoption of the energy-saving and environment-friendly casting and smelting production method, both emission and the smelting cost can be substantially reduced.
Description
technical field [0001] The invention relates to a casting and smelting production method, in particular to an energy-saving and environment-friendly casting and smelting production method, belonging to the technical field of metal smelting methods. Background technique [0002] The casting and smelting industry is relatively polluting, and cupolas emit serious pollutants, which have been strictly controlled by major provinces and cities; the use of intermediate frequency furnaces for smelting consumes a lot of energy, which is unbearable for most enterprises. Some centrifugal casting, investment casting, negative pressure and other precision casting enterprises adopt the mode of direct purchase of molten steel for production, which not only increases the production cost, but also limits the output of the enterprise and cannot meet the production demand. [0003] Adopting the energy-saving and environment-friendly casting smelting production method of the present invention, t...
