Description
Technical field
The present invention relates to casting technology fields, more particularly to a kind of preparation method of Nodulizing agent for nodular cast iron.
Background technology
Spheroidal graphite cast-iron is a kind of valuable high-strength cast iron material to grow up on the basis of gray cast iron.Spheroidal graphite is cast
Iron greatly reduces the effect of isolating to matrix, mechanical property has than gray cast iron significantly to be carried since graphite is in spherical distribution
Height, comprehensive performance is close to steel.It is based on its excellent performance, has been successfully used to cast some stress complexity, it is intensity, tough
The more demanding part of property, wearability.Spheroidal graphite cast-iron rapidly developed for be only second to gray cast iron, using very extensive cast iron
Material.
Currently, the production process in spheroidal graphite cast-iron needs to carry out spheroidising to material, the effect of spheroidising is to make stone
Ink improves the mechanical property that matrix pattern improves casting in crystalline growth duration glomeration, when carrying out spheroidising step,
If nodulizer is improper, it is easy to which it is unstable to seriously affect product quality performance for the defect for causing decaying spheroidisation.
Invention content
In order to make up the defect of prior art, the present invention provides a kind of preparation method of Nodulizing agent for nodular cast iron.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of preparation method of Nodulizing agent for nodular cast iron, each component mass percent are：Magnesium 5-6%, silicon 44-47%, rare earth
1.5-2.2%, nickel 1-2%, aluminium 0.1-0.3%, barium 1-2%, manganese 0.2-0.6%, surplus are iron.
Further, each component mass percent is：Magnesium 5.4%, silicon 46%, rare earth 1.8%, nickel 1.5%, aluminium 0.2%, barium
1.5%, manganese 0.4%, surplus are iron.
Further, it is made of following making step：
S1. it presses each element weight percent and chooses raw material；
S2. the step S1 material taken are added in medium-frequency induction furnace and carry out melting；When medium-frequency induction furnace temperature reaches
At 1200 DEG C -1300 DEG C, power is adjusted to 170-180KW, then utilizes inserted link made of the round steel of Φ 18- Φ 20 every 4 points
Clock plugs in pricker once until raw material all melts；
S3：It is stirred evenly after material all fusing, nodulizer is obtained after cast is cooling.
The present invention has the advantages that：
The features such as nodulizer of the present invention has nodularization effect good, and production cost is low, spheroidization ability is strong carries out spheroidizing reacion and is not easy
It is influenced by other tension-active elements, the nodulizer can effectively improve the intensity, hardness and heat resistance of spheroidal graphite cast-iron in addition.
