The mode of operation of the utility model system is as follows.
When adopting the work of calcic sweetening agent, the first ball valve 7 is opened, and the second ball valve 8 is closed shape, carrier gas and a spray gun are opened (not shown on figure), spray gun drops to " melt top " position, open calcium agent gate valve 6, calcic material is transported in a selected spray gun by a valve in ball valve 11 and ball valve 12 in carrier gas stream.
Spray gun is transferred to melt depths.Feed intensity regulates by means of variable valve 13, after giving enough the sweetening agent of necessary amounts, spray gun is proposed to " melt top " position and cuts off calcic sweetening agent feed by calcium agent gate valve 6, closes carrier gas and spray gun is mentioned to " top " position.The operation of winding-up calcic material, like this from liming materials to batch can 2s, by a winding-up in calcium agent gate valve 6, variable valve 13, pneumatic blender 14 and ball valve 11 or ball valve 12 to one in two selected spray guns.
When the mixture work that adopts liming materials and granular magnesium, the second ball valve 8 is closed, and the first ball valve 7 is opens shape.Open carrier gas and a spray gun is dropped to " melt top " position, open calcium agent gate valve 6 and make the calcic material in carrier gas stream be transported to a selected spray gun by a ball valve (ball valve 11 or ball valve 12).Spray gun is transferred to molten iron depths.The feed intensity of calcic material is regulated and controled by variable valve 13.After spray gun fully slips into, open granular magnesium and measure the granular magnesium feed to batch can 1, magnesium material enters pneumatic blender 14 by magnesia mixture gate valve 5, rotor material feeder 16, divider 15, meanwhile, from " 0 ", is increased to " prescribed value " stably to magnesium intensity.After the magnesium material of the desired number of having jetted, turn off magnesium feed, spray gun is proposed to " melt top " position.The operation of winding-up liming materials and granular magnesium mixture, from granular magnesium, measure to batch can 1 and liming materials to batch can 2s like this, via magnesia mixture gate valve 5 and calcium agent gate valve 6, variable valve 13, rotor material feeder 16, divider 15, pneumatic blender 14 and a selected ball valve 11 or ball valve 12, deliver to a selected spray gun.
When system is worked with granular magnesium material (subsidiary calcic material) separately, the first ball valve 7 is closing condition, and the second ball valve 8 is opens shape.In two spray guns, chosen one (singly blow granular magnesium that) drops to " melt top " position, opens carrier gas and being inserted into melt depths under rifle.Spray gun is opened rotor material feeder 16 after fully slipping into, at this moment the feeding strength of granular magnesium is brought up to " set(ting)value " from what " 0 " reposefully.After the magnesium material of the desired number of having jetted, rotor material feeder stops feed, and spray gun is brought up to " melt top " position, turns off carrier gas and supplies with and carry rifle to " upper position ".Singly blow the operation of magnesium material and from granular magnesium, measure to batch can like this, be accomplished via one in magnesia mixture gate valve 5, rotor material feeder 16, divider 15, the second ball valve 8 and ball valve 9 or ball valve 10, send into selected that spray gun that singly blows granular magnesium.
The essence (main points) of this multifunctional molten iron desulphurization system of applying for a patent is: granular magnesium batch can exit exists a rotor material feeder, just can measure exactly and provide granular magnesium, its error is not more than 2 ﹪, no matter this is when being blown into granular magnesium separately and or be all very necessary during the mixture of jet liming materials and granular magnesium.So just guarantee under winding-up simple substance material and compound both of these case feed equably, avoided spray gun passage to stop up, reduced the fierce degree of process.
Be configured in granular magnesium and measure to the divider on batch can defeated magnesium pipeline out, can granular magnesium can be blown into the pneumatic blender mixing with liming materials by means of the first ball valve 7 and the second ball valve 8, can be blown into again and singly blow the spray gun that granular magnesium is used.
Utilize this multifunctional molten iron desulphurization system of applying for just to have two cover feeder systems concurrently---for granular magnesium with for calcic material, and respectively there is own unique Controlling System, simultaneously wherein each system can guarantee independently feed system and both can work independently, also can work compound.
Can find out in sum: this cover multifunctional molten iron desulphurization system can import to even friction sweetening agent when desulfurizing iron, can adopt broad variety sweetening agent according to the initial and final argument (chemical constitution, temperature etc.) of the kind of existing sweetening agent and quality (have what kind material, have what quality material just with what to expect) and molten iron, thereby solved the problem proposing, reached desired result.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
