8. the automobile engine to exhaust adapter as described in any claim in claim 1-7 and its production technology, its feature
It is, concrete operation step is as follows：
（One）Melting raw material：
A, by automobile engine to exhaust adapter raw material add smelting furnace in, the temperature in smelting furnace is brought up to 1600 DEG C to 1620 DEG C,
Raw material is smelted formation alloy solution；
B, alloy solution obtained in the previous step is cooled down, during cooling, water-cooled is combined with air cooling, first adopts water-cooled with 28-30
DEG C/alloy solution water-cooled to 400-410 DEG C of formation alloy, is then air cooled to 300-310 DEG C, then adopts water by the cooldown rate of s
The cold cooldown rate with 13-15 DEG C/s is by alloy water-cooled to room temperature；
C, heating, carry out secondary smelting in the alloy addition smelting furnace after previous step is cooled down, the temperature in smelting furnace are brought up to
1600 DEG C to 1620 DEG C, alloy is formed alloy solution by secondary smelting；
D, boiling hot bag, the alloy solution in smelting furnace is poured into casting ladle, carries out scalding bag；
After e, boiling hot bag finish, the alloy solution in casting ladle is poured in electric furnace, the temperature in electric furnace is warming up to 1650 DEG C extremely
1670 DEG C, heat 5 minutes to 8 minutes, the alloy solution in electric furnace is poured into casting ladle, ladle-to-ladle cooling；
F, ladle-to-ladle after, the alloy solution in casting ladle is poured into electric furnace, temperature is down to 1480 to 1510 DEG C, casting ladle bag hole according to
The secondary addition nodulizer of 1.4%-1.5% and the inovulant of 0.2%-0.3%, are covered on nodulizer, inovulant with sheet metal, and smash
Real, steel-sheet thickness is 0.5mm-1mm；
G, the alloy solution in electric furnace is poured into the opposite side of casting ladle indent, spheroidizing reacion 50s to 65s, after spheroidizing reacion is abundant,
Spread the slag agent of one layer of collection, quickly skim, after quickly skimming, be sprinkled into swelling perlite powder on alloy solution surface immediately, twice of slag hitting,
After the completion of slag hitting, form alloy solution to be cast, be poured in five minutes；
（Two）Prepared by wax-pattern：Using low-temperature wax and mechanical casting technology, make consistent with automobile engine to exhaust Taper Pipe cast member
And include the wax-pattern of insulated feeder, and wax-pattern is repaired, using wax base abluent, wax-pattern is carried out afterwards；
（Three）In step（Two）Shell model sand mold is made on prepared wax-pattern；
（Four）Dewaxing：Using steam dewaxing, the pressure of steam is 0.6MPa, and the time is 18-55 minute, and should first will protect before dewaxing
The EVA adhesive film at warm rising head position is taken off, prepared shell mould；
（Five）Shell mould roasting；
（Six）By step（Five）Roasting shell mould is put in the sandbox by formative technology preparation, and blend compounds band seals on this shell mould
Cast gate for cast and insulated feeder, are then placed in, through the mixed sand prepared, using foundry jolter after piling mixed sand again
Carry out ram-jolt, form sand mold；
（Seven）By step（Six）Sand mold after ram-jolt and sandbox plane strike off, and prick a gas in mould surface at interval of 15cm
Eye, this core is pricked to from model surface 4-6cm；
（Eight）Cast, is processed to the foundry goods after moulding by casting；
（Nine）The corrosion-resistant skin of paint that foundry goods coating after processing is obtained can get complete engine exhaust adapter.
