Description
Technical field
The present invention relates to a kind of water horizontal continuous casting and produce the process and the crystallizer thereof of iron bronze (C194) alloy made-up belt.
Background technology
The chemical composition percentage of iron bronze (C194) alloy is: Fe2.1～2.5%, P0.015～0.15%, Zn0.05～0.2%, Pb≤0.03%, Cu surplus; The GBQFe2.5 that is equivalent to CNS, the composition of producing with this alloy material is qualified, cast sturcture is even, surperficial flawless long paper made-up belt (width 200～440mm, thickness 12～18mm, length 40～100m), mill operations such as face, cold rolling, heat treatment and finish rolling through road later, can produce and be used to make blaster fuse frame material that semiconductor and IC uses and electronic connector etc.Make wherein that the compound of iron and iron evenly distributes in the strand, and defectives such as strand flawless, raw edges are even more important.
At present, produce iron bronze C194 alloy roll coil of strip base both at home and abroad, all adopt the method for big ingot semi-continuous casting-hot rolling, promptly at first produce block ingot casting with vertical semi-continuous casting, heat hot rolling again and end in hot rolling and carry out the solution treatment of water-quenching, long flow path, the equipment investment of this production technology are big, and the process conditions of solution treatment control difficulty, cause iron bronze C194 alloy made-up belt cost height, the energy consumption of producing big, difficult quality is stable.
Summary of the invention
The purpose of this invention is to provide a kind of water horizontal continuous casting and produce the process of iron bronze (C194) alloy made-up belt, it is satisfying under the satisfactory prerequisite of manufactured finished, can reduce operation, and can reduce equipment investment greatly, reach the purpose that reduces production costs and alleviate working strength of workers.
Another object of the present invention provides the crystallizer that a kind of water horizontal continuous casting is produced iron bronze (C194) alloy made-up belt, this equipment subsidiary level continuous casting is produced the enforcement of iron bronze (C194) alloy made-up belt process, and iron bronze (C194) the alloy made-up belt of producing is had good quality.
For achieving the above object, the present invention takes following design:
A kind of water horizontal continuous casting is produced the process of iron bronze alloy made-up belt, and described process step is as follows:
1), adds in the melting furnace according to iron bronze C194 alloying component batching;
2) add an amount of deoxygenation refining agent, carry out the melting of alloy;
3) to be adjusted to branch after melting furnace fusing qualified for alloy, and after reaching appropriate melting temperature (1190～1210 ℃), liquation is poured in the holding furnace by chute, further adjust alloying component at holding furnace, and be stabilized in 1125～1135 ℃ scope by the input voltage control casting temperature of control electric induction furnace by the sampling rapid analysis;
4) through the crystallizer cooling processing of water spray cooling tube is installed in outlet, adopt drawing-stop-the anti-casting technique program that pushes away of this alloy of computer control, carry out the solution treatment of water-quenching in the crystallizer exit;
5) continuous tapping bronze C194 alloy roll coil of strip base, each roll coil of strip makes roll coil of strip Weight control an amount of by the control of strand length, is sent to line and mills the face machine outward and mill face, obtains qualified iron bronze C194 alloy band.
Because iron bronze C194 alloyed iron content is than higher, the fusing point of Fe is littler than copper, bigger than copper to the affinity of oxygen than copper height, proportion, alloyed copper water mobile poor, so iron can be distributed in copper water more equably, the intermediate frequency coreless induction furnace that adopts 500～800Hz in the said method is as melting furnace.
Because of iron bronze C194 alloy is a solid solution strengthened alloy, only when casting, take suitable crystallizer and cooling condition, and the suitable process that is pulled, could normally produce qualified long roll coil of strip base continuously, so the present invention has adopted the crystallizer of special construction and has adopted drawing-stop-the anti-casting technique program that pushes away of this alloy of computer control.
A kind of for implementing the custom-designed crystallizer of said method step 4), it includes upper and lower two block structures and measure-alike main body cooled copper and is positioned at the graphite cake on its inboard four limits, in two cooled copper, vertically offering two groups of cooling water circulation lines respectively, each is organized the cooling water circulation line and is made of the corresponding outlet pipe of some water inlet pipes arranged side by side, and the plug of adjustable water saving flow and flow velocity is housed in each water inlet pipe.The made-up belt port of export at crystallizer is equipped with the water spray cooling tube, makes strand can carry out the shrend chilling, is beneficial to solution treatment, and the qualified C194 alloy made-up belt of production is guaranteed.
Inboard and the limit portion graphite block position contacting in two cooled copper of crystallizer, respectively opened one group of flat square groove, solved the too fast problem of limit portion cooling, the copper coin made-up belt that can help continuous casting is difficult for producing thermal stress and crackle, the alloy liquid cave of continuous casting reduces, foudry line is steady, reduces the loose and shrinkage cavity of strand.
Crystallizer up and down two graphite cakes go deep into a side of burner hearth, respectively be processed with several inclined holes, make iron bronze C194 alloy liquid can steadily enter crystallizer.
Advantage of the present invention is: can adopt the method for horizontal casting to produce qualified C194 roll coil of strip base, after milling face, can directly carry out cold rolling, the length of the roll coil of strip can be selected according to the ability of cold-rolling mill, do not need to invest expensive ingot blank heating furnace and hot-rolling mill, technological process is short, and equipment investment is less relatively, and production cost is lower, energy consumption is little, and working strength of workers is little.
