Description
Technical field
The present invention relates to alterant technical field, particularly relate to a kind of alterant for wear-resistant steel forging.
Background technology
Alterant is widely used in metallurgy industry, and Metamorphism treatment is to improve alloy microstructure, improves alloy mechanical property
Conventional effective means, especially in refining alloy microstructure, and then improve the intensity of alloy, hardness, percentage elongation, impact flexibility and
The aspects such as heat stability, have important function and meaning.Conventional alterant is divided into alloy inoculant and compound alterant two big
Class.Alterant element in alloy inoculant exists with simple substance and/or intermetallic compound form, melts also after adding metal bath
It is diffused in melt, plays metamorphism.Alterant element in salt alterant exists with compound form, adds metal bath
Afterwards with molten metal generation displacement reaction, alterant element enters melt, plays metamorphism.
It is believed that the feature mechanical property to wear-resistant steel forging such as graphite form in wear-resistant steel forging tissue, size, quantity
Energy, machinability have vital impact, control the graphite features in wear-resistant steel forging tissue and are i.e. obtained in that required
Wear-resistant steel forging ferrum property.
If controlling the growth of primary austenite in wear-resistant steel forging process of setting, making primary austenite is that spatial network is sent out
Exhibition, then can limit the growth of graphite during eutectic freezing, is conducive to obtaining the graphite that shape bending, size are tiny, thus
Reach to improve the purpose of wear-resistant steel forging mechanical property.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of alterant for wear-resistant steel forging, promotes
The tissue of wear-resistant ball changes, and makes the intensity of wear-resistant ball obtain beyond thought significantly improving, hardness up to 72HRC, and
