Abstract
The invention discloses am on-line production method of clutch housing and flywheel housing. The clutch housing and flywheel housing on-line casting method comprises the steps that: iron powder is processed into iron particles, the iron particles are melted in an autoclave, the material is delivered into a medium-frequency furnace, quenching and tempering are carried out, examination is carried out, casting is carried out by using molds, and products are obtained. The method provided by the invention is advantageous in that a secondary heating process for melting cast iron parts is not needed, such that energy is saved, and production cost is reduced.
Description
Technical field
The invention discloses the online production method of a kind of clutch housing, fly wheel casing, belong to the engineering goods production technical field, is that direct-on-line is not processed clutch housing, fly wheel casing product when the gray iron liquation is cast into the gray iron piece concretely.
Background technology
Clutch housing, fly wheel casing are the component commonly used of engineering goods, they by after watering pig and heating once more casting form.The operation of known casting gray iron is: iron powder → abrasive grit → pressure furnace fusing → casting → gray iron iron block; The operation of casting clutch housing, fly wheel casing product is: gray iron ingot iron → intermediate frequency furnace fusing → modified → chemical examination → die casting → product.Can find out from above-mentioned twice production process; When conventional cast clutch housing, fly wheel casing product; To refrigerative gray iron iron block be warmed to 1300～1350 ℃ temperature again, after the fusing, the ferrous solution that melts be carried out modified, chemical examination; Cast then, process clutch housing, fly wheel casing product.The defective that the technology of this existing casting clutch housing, fly wheel casing exists in practicality is need be with the fusing of gray iron piece secondary heating, and the waste mass energy increases production cost.
Summary of the invention
The online production method that the purpose of this invention is to provide a kind of clutch housing, fly wheel casing utilizes this online production method to produce clutch housing, fly wheel casing, does not need secondary heating fusing gray iron piece, and save energy reduces production costs.
Taked following technical scheme for realizing the object of the invention:
The online production method of a kind of clutch housing, fly wheel casing, the online production method of described clutch housing, fly wheel casing: iron powder → abrasive grit → pressure furnace fusing → intermediate frequency furnace → modified → chemical examination → die casting → product.
Described entering intermediate frequency furnace temperature modified, chemical examination is 1300～1350 ℃.
Characteristics of the present invention are at the online direct production clutch housing of gray iron production line, fly wheel casing, and production technique is simplified; Its remarkable advantage is a save energy, reduces product cost.
