Description
Technical field
The utility model relates to molten iron refining techniques field, particularly relates to a kind of molten iron pretreatment and attaches formula deslagging device.
Background technology
Molten iron pretreatment is significant to raising steel quality, expansion kind, and desulfurizing iron is one of pretreated important means of molten iron, and after desulfurizing iron, quality has larger improvement.But the scum sulfur content after desulfurizing iron process is very high, to steelmaking process and quality extremely harmful.If after the scum that this part sulfur-bearing is higher enters converter, the consumption of lime will be increased, and sulphur also may enter molten steel from slag, like this, the pretreated successful of desulfurizing iron will be made to reduce.Therefore, after molten iron pretreatment, need increase to skim operation, the sulfur-containing solid slag on removing molten iron surface.Particularly for molten iron and the steel mill realizing less-slag melting operation of smelting low-sulfur steel grade, molten iron deslagging is particularly important.
Current molten iron deslagging method mainly contains mechanical slagging-off method, drags for slag method, deslagging method, skimming method, vacuum slag absorbing method and slag trap pushing off the slag method etc.Wherein because having, slagging-off efficiency is high, equipment simple, be easy to the advantages such as operation is extensively adopted by iron and steel enterprise mechanical slagging-off method, and mechanical slagging-off method on molten iron face, makes horizontal motion with slag removal device, slag clawed ladle and enters slag pan.But this kind of deslagging process moves on molten iron face because of device for removing slag, inherently produces wave making motive force and friction belt power to molten iron, so clawing along with slag, molten iron is inevitable also to be taken out of.Slag removal device immersion depth, by range estimation, can not accomplish that slag removal device immersion depth is consistent with thickness of slag layer, and each position thickness of slag layer is also different, as slag removal device immersed shallow then can only to claw above a part of slag, slag removal device immerses dark, can directly molten iron be taken off out.Clean in order to be removed by solid slag, the degree of depth of generally skimming all can be greater than thickness of slag layer, so taking out of of molten iron is inevitable when skimming.The slag clawed often can condense into block, illustrates in slag with a large amount of iron.
The Chinese patent of application number 200710015162.2 (applying date is on July 30th, 2007) discloses one " molten iron pot narrow gap gas-blowing slag-removing device and operating procedure ", its molten iron pot narrow gap gas-blowing slag-removing device has a mechanical arm be made up of the first hydraulic cylinder and the second hydraulic cylinder, the first ultrasonic transformer and the second ultrasonic transformer and turning joint, mechanical arm is provided with blowpipe, blowpipe is provided with gas connection pipe and nozzle, and nozzle is narrow slit shape nozzle; Its operating procedure is: first gas connection pipe has been communicated with nitrogen tube or air compressor; By hot-metal bottle after position inclination certain angle of skimming, adjusted the top of the slag distance of narrow slit shape nozzle and hot-metal bottle by amplitude-variable mechanical arm, then pass through narrow slit shape nozzle to top of the slag nitrogen-blow or compressed air, liquid slag is driven to outside hot-metal bottle mouth.It is high that the method has the rate of skimming, and hand labor intensity is low, the advantage that environmental pollution is little.This deslagging process adopts pneumaticly to catch up with slag and the molten iron pretreatment deslagging process combined of skimming, on the basis of mechanical slagging-off method, be equipped with gas catch up with slag, because blowing gas can cause slag blanket above to lower the temperature rapidly crust, gas is caused to catch up with slag slagging-off rate lower, and the solid slag that finally can not automatically overflow still needs to adopt slag removal device to claw, mechanical slagging-off method Problems existing therefore can not be avoided.
