Abstract

The present invention relates to metal working technical area, especially a kind of method producing white cast-iron with manganese, chromium, silicon and the pig iron, chemical composition percentage is:Manganese 9% 11%, chromium 5% 8%, silicon 3% 5%, surplus is the pig iron;White cast-iron is made by specific proportioning with common materials such as manganese, chromium, silicon, the pig iron, steel scraps, air chill all occurs for structure of cast iron, and high frequency heat treatment is needed not move through in process, has many advantages, such as that surface strength height, inside and outside hardness are consistent;It is suitble to the component for rubbing for a long time such as production piston, piston rod and plunger.

Description

A method of white cast-iron is produced with manganese, chromium, silicon and the pig iron
Technical field
The present invention relates to metal working technical area, especially a kind of side producing white cast-iron with manganese, chromium, silicon and the pig iron Method.
Background technology
Its appearance of cast iron is generally iron black color or grey, and light tone coating is sprayed after polishing is needed after being cast as product, However sprayed coating is not appropriate for due to often rubbing against for piston rod, plunger etc..Therefore it is naturally presented after a kind of casting of urgent need white The cast iron of mouth state.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of production method of white cast-iron.
The technical scheme is that:
A method of white cast-iron is produced with manganese, chromium, silicon and the pig iron, it is characterised in that:Its chemical composition percentage is: Manganese 9%-11%, chromium 5%-8%, silicon 3%-5%, surplus are the pig iron.
A method of white cast-iron is produced with manganese, chromium, silicon and the pig iron, is as follows:
By weight percentage, by manganese 9%-11%, chromium 5%-8%, silicon 3%-5%, surplus is that the pig iron carries out dispensing;
The pig iron is put into after being melted in induction furnace, carries out pre-deoxidation operation, ferrochrome, ferromanganese and ferrosilicon is then added, obtains Molten iron;It takes molten iron sample to carry out on-the-spot sample analysis to be adjusted the molten iron to the requirement of qualified molten iron according to analysis result;By iron Coolant-temperature gage is increased to 1550 DEG C~1600 DEG C, carries out final deoxidizing, comes out of the stove;When temperature is down to 1400 DEG C~1460 DEG C, start to pour Note, obtains cast iron;The cast iron of acquisition is heated to 850 DEG C~950 DEG C, progress is air-cooled, is then heated to 350 DEG C~500 DEG C tempering 2h~5h obtains white cast-iron.
Ferrochrome, ferromanganese and ferrosilicon first carry out baking processing, to remove ferrochrome, ferromanganese and ferrosilicon before being added in induction furnace Moisture content and surface greasy dirt.
Beneficial effects of the present invention are:Spoken parts in traditional operas is made by specific proportioning with common materials such as manganese, chromium, silicon, the pig iron, steel scraps Air chill all occurs for cast iron, structure of cast iron, and high frequency heat treatment is needed not move through in process, has surface strength height, inside and outside The advantages that hardness is consistent;It is suitble to the component for rubbing for a long time such as production piston, piston rod and plunger.
