Description
Technical field
The utility model relates to a kind of smelting furnace, and especially a kind of architecture advances of caststeel smelting furnace belongs to the metallurgical casting equipment technical field.
Background technology
Cast iron and cast steel are important plant equipment manufactured materials.Before the seventies, cast steel generally adopts electric arc furnace smelting, after the seventies, uses intermediate frequency furnace or coreless induction furnace gradually instead and smelts.These are smelted, and not only power consumption is very big, is referred to as electric-tiger, and need add the water cooling air core coil.The charing hot-air stove is then adopted in the smelting of cast iron usually, claims furnace cupola again, is about to cast iron base and charcoal and adds melting in the stove together.Though this smelting process energy savings because mix easy increase phosphorus content with charcoal and circulate other impurity, therefore the fusing point of cast steel exceeds nearly 300 ℃ than cast iron is common in addition, in fact can't adopt furnace cupola steel-making.
Summary of the invention
The purpose of this utility model is: at the problem of cast steels melting energy consumption, propose a kind ofly can guarantee cast steel quality, and save the carbon combustion caststeel smelting furnace of the energy.
In order to reach above purpose, carbon combustion caststeel smelting furnace of the present utility model contains the caststeel smelting furnace of being made by insulation material (9), also comprise charcoal combustion furnace (6), air duct (3) communicates by in air port (5) and the charcoal combustion furnace (6), and charcoal combustion furnace (6) is inner to communicate by in flame pipeline (7) and the flame jet (8) that is arranged on caststeel smelting furnace (9) bottom and the caststeel smelting furnace (9).
It is the outer combustion furnace air compartment (4) that surrounds of charcoal combustion furnace (6) that the utility model further improves, described air duct (3) communicates by combustion furnace air compartment (4) the combustion furnace air compartment (4) peripheral with being enclosed in charcoal combustion furnace (6), and described combustion furnace air compartment (4) communicates with charcoal combustion furnace (6) inside by air port (5).So more help making full use of heat energy, and several air ports (5) can be set as required, thereby improve melting efficiency.
During smelting, in caststeel smelting furnace, put into steel billet, light the charcoal that is placed in the charcoal combustion furnace.When the air of introducing from the external world enters the combustion furnace air compartment by air duct, be blown in the charcoal combustion furnace through air port again, with the abundant mixed combustion of charcoal wherein, form thermal-flame.This thermal-flame is through the flame pipeline, by the flame jet ejection, and the steel billet in the fusing caststeel smelting furnace is finished the melting of cast steel.
As can be seen, the melting of above cast steel is finished by the heat that the charcoal burning discharges fully, and without electric energy, so smelting cost is low, saves the energy.The appropriate design of whole furnace heats circulation has then been avoided the direct contact of charcoal, steel, has prevented the increase of cast steel phosphorus content and other impurity component, has guaranteed smelting quality.
Obviously, the utility model ingenious conception, simple in structure, cost economy.After estimating to release, the popular welcome of metallurgy industry will be subjected to.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Fig. 3 is the structural representation of the utility model embodiment three.
The specific embodiment
Embodiment one
The carbon combustion caststeel smelting furnace of present embodiment as shown in Figure 1, the main composition part is as follows: 1---air blast, 2---the air preheat bucket, 3---air duct, 4---the combustion furnace air compartment, 5---air port, 6---the charcoal combustion furnace, 7---the flame pipeline, 8---flame jet, 9---caststeel smelting furnace, 10---feed the charcoal mouth, 11---feed the charcoal machine rotor, 12---the charcoal feeding mouth, 13---body of heater, 14---the breeze outlet.The wherein caststeel smelting furnace 9 and the 6 close arrangements of charcoal combustion furnace of making by the thermal insulation fire-resistant material.The fire door of caststeel smelting furnace 9 surrounds the air preheat bucket 2 that connects air blast 1 air outlet.This air preheat bucket 2 communicates with the combustion furnace air compartment 4 that is enclosed in charcoal combustion furnace 6 peripheries by air duct 3.Combustion furnace air compartment 4 communicates with charcoal combustion furnace 6 inside by air port 5, and charcoal combustion furnace 6 inside communicate by in flame pipeline 7 and the flame jet 8 that is arranged on caststeel smelting furnace 9 bottoms and the caststeel smelting furnace 9.Body of heater 13 bottoms of charcoal combustion furnace 6 are provided with the breeze outlet, and top is equipped with and is fed charcoal machine rotor 11, and is more convenient when smelting like this.
During use, in caststeel smelting furnace 9, put into steel billet, light by feeding the charcoal that charcoal machine rotor 11 is put into charcoal combustion furnace 6.After air blast 1 started, the air that is blasted by the external world was blown into combustion furnace air compartment 4 by air duct 3 after 2 heating of air preheat bucket, be blown in the charcoal combustion furnace 6 through air port 5 again, with charcoal mixed combustion wherein, forms thermal-flame.This thermal-flame is through flame pipeline 7, by flame jet 8 ejections, and the steel billet in the fusing caststeel smelting furnace 9 is finished the melting of cast steel.
Charcoal, steel are separated from each other in above process, so the cast steel composition can not change.The mode of preheating and tempering heating has then guaranteed required heating-up temperature, has effectively utilized the energy, has reduced the loss of heat.Therefore facts have proved, present embodiment design science, rational in infrastructure, can guarantee the cast steels melting quality, and production cost reduces greatly.
