Abstract
A nodulizing agent, a plurality of mixing agents, molten metal degassing agent powder, anorthite sand, a nodulizing barrel and a dam are included in multiple processing of molten iron of nodular cast iron. The nodulizing agent is uniformly laid in a pit on the left side of the dam inside the nodulizing barrel, the plurality of mixing agents cover the nodulizing agent uniformly, the molten metal degassing agent powder covers the plurality of mixing agents uniformly, the anorthite sand covers the molten metal degassing agent powder uniformly, and the molten metal degassing agent powder and the anorthite sand are compacted through a tamper flat end. The smelted molten iron is poured into the right side of the dam. The nodulizing reaction time is postponed at the beginning of pouring of the molten iron through covering of the nodulizing agent with a plurality of covering substances, after a large amount of molten iron is poured, the plurality of covering substances are molten, the covering effect is ineffective, the nodulizing agent churns drastically for reaction in the molten iron, and the good nodulizing effect is achieved; by the aid of the drastic churning reaction of the molten iron, a degassing and refining matrix structure agent which plays a role in covering is subjected to full melting diffusion and multiple reactions, and the multiple high-effect processing is obtained through one operation. The high-quality nodular cast iron is obtained through the multiple processing of the molten iron of the nodular cast iron.
Description
Technical field technology neck
The present invention relates to Ductile Iron Casting technique, the especially multinomial processing of molten ductile iron.
Background technology
Ductile Iron Casting adopts furnace cupola or electric furnace to carry out the furnace charge melting at present, in the nodularization bag, nodulizer is coated with magnesium iron bits, magnesium iron fragment, rice-straw ash or perlite, only to there is ball covering on soil agent individual event performance, because coverage effect is bad and cover the individual event performance to make nodulizer cross in advance fast response or nodularization of poor quality, cause nodularization poor quality or nodularization failure.
Summary of the invention
The invention provides the multinomial processing of a kind of molten ductile iron, they be that the coverture of nodulizer is again the inorganic agent of the multinomial processing of molten ductile iron, complete the covering effect to nodulizer in the nodularization bag after, the liquid iron balling fierceness obtains compound inoculated, degassed and abundant fusing refinement matrix thing fully and spreads and multinomial reaction in seething, obtain high-quality magnesium iron.
The technical solution adopted for the present invention to solve the technical problems is: the multinomial processing of molten ductile iron is comprised of nodulizer, multiple intermixture, molten metal degasser powder, anorthite sand, nodularization bag, dykes and dams.Even lay nodulizer in the pit of dykes and dams left side in the nodularization bag, the multiple intermixture of uniform fold on nodulizer, uniform fold molten metal degasser powder on multiple intermixture, on molten metal degasser powder, uniform fold anorthite sand is also with the compacting of sand shop tack.Melted molten iron rushes the dykes and dams right side.
Multiple intermixture is: Antaciron Si65Fe adds and accounts for molten iron gross weight 1.4%, granularity 5-10 millimeter; Silicon barium-ferrum alloy Si64Ba5Fe adds and accounts for molten iron gross weight 0.5%, granularity 5-10 millimeter; Antimony ore powder Sb2O3 adds and accounts for molten iron gross weight 0.008%, granularity≤0.2 millimeter; Mix to choose and mix evenly.
The invention has the beneficial effects as follows: the multinomial processing of molten ductile iron, seethe while stirring and carry out fully compound inoculated, desulfurization, degassed and refinement matrix agent fusing diffusion homogeneous reaction at liquid iron balling.The postponement decaying spheroidisation time reaches 20 minutes.The nodularization rate reaches the 1-2 level, and the graphite sphere diameter reaches the 7-8 level, and the matrix of refinement reaches fine pearlite, and the casting qualification rate reaches 93%, obtains high-quality iron casting.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing is the longitudinal profile structure chart of the multinomial processing of molten ductile iron.
In accompanying drawing 1, nodulizer, 2, multiple intermixture, 3, molten metal degasser powder, 4, anorthite sand, 5, the nodularization bag, 6, dykes and dams.
The specific embodiment
Accompanying drawing is the longitudinal profile structure chart of the multinomial processing of molten ductile iron of 600 kilograms of molten iron production QT500-7 trade mark nave bosses of nodularization.In the pit of dykes and dams (6) in nodularization bag (5) left side, even lay nodulizer (1) FeSiMg8RE5 is 7.8 kilograms in the accompanying drawings, and granularity is the 20-30 millimeter, by 1.3% of spheroidization molten iron weight, adds; Nodulizer (1) above FeSiMg8RE5 the multiple intermixture of uniform fold (2) to account for 60% of molten iron gross weight 1.4% amount be 5.1 kilograms, on the multiple intermixture (2) covered, to account for molten iron gross weight 0.4% be 2.4 kilograms for uniform fold molten metal degasser powder (3) Re, Ti, NaNO3, at molten metal degasser powder (3) Re, Ti, above NaNO3,4 millimeters thickness of uniform fold, granularity are 20-40 purpose anorthite sand (4) CaOAl
2O
3.2SiO
2And with the compacting of sand rammer tack.400 kilograms of melted molten iron are poured to the interior dykes and dams of nodularization bag (5) (6) right side, and the amount of pouring accounts for 2/3rds of spheroidising iron water amount.When starting to pour the small part molten iron, anorthite sand (4) gathering is covered with molten metal degasser powder (3) Re, Ti, NaNO3, has postponed the nodulizer spheroidizing reacion time, wait pouring molten iron, increase while raising with temperature, nodulizer (1) covers anorthite sand (4) CaAl above FeSiMg8RE7
2O
3.2SiO
2, molten metal degasser powder (3) Re, Ti, NaNO3 and multiple intermixture (2) fusing diffusion lose the covering effect, nodulizer (1) FeSiMg8RE5 fierceness in more molten iron is seethed reaction, make molten iron obtain sufficient nodularization, once-combined breeding, take off abundant fusing diffusion and the homogeneous reaction of oxygen hydrogen nitrogen and the agent of refinement matrix, after the complete stirring molten iron of spheroidizing reacion, skim, add multiple intermixture (2) remain 40% be 3.3 kilograms, stir and process for the second time molten iron, pour again remaining 1/3rd the interior molten iron temperature of the high nodularization bag of 200 kilograms of iron water extraction, stir molten iron, molten iron surface coverage heat preserving agent in nodularization, get the molten iron of nodularization and do chill block inspection nodularization quality, be poured the molten iron of nodularization after qualified in 20 minutes.Apply multinomial processing magnesium iron water operation and once can play multinomial performance processing molten iron, reaction evenly.Can produce continuously.
Multiple intermixture is: Antaciron Si65Fe adds and accounts for molten iron gross weight 1.4%; Granularity 5-10 millimeter; Silicon barium-ferrum alloy Si64Ba5Fe adds and accounts for molten iron gross weight 0.5%; Granularity 5-10 millimeter; Antimony ore powder Sb
2O
3Add and account for molten iron gross weight 0.008%, granularity≤0.2 millimeter; Mix to choose and mix evenly.
