Abstract
The utility model provides a survey coupon for casting analysis of molten iron shrinkage cavity shrinkage porosite incline. In order to satisfy the needs that casting molten iron shrinkage cavity shrinkage porosite formed the incline analysis, this paper discloses the many functional test appearance piece that is connected to form by three different thickness cross -sections block part. Whole " worker " the font that is of this survey coupon, block 2 has less volume -modulus and a very fast solidification speed for a long narrow boards, circulates and blocks solidifying the molten iron of in -process with block 1 and block 3. The volume -modulus of block 1 is used for making shrinkage cavity shrinkage porosite forming conditions rather than the connection slightly greatly than block 2. Block 3 has and inclines form the shrinkage cavity shrinkage porosite with block 2 after the biggest volume -modulus is connected, easily installs the rising head in this block casting mould part side or top in addition and implements the feeding, perhaps installs volume or linear displacement sensor and thermocouple and is used for graphite inflation and feeding characteristic detection and analysis. The utility model is used for casting and metallurgical field.
Description
Technical field
This utility model belongs to casting and field of metallurgy, and in particular to a kind of to be used for molten casting iron shrinkage cavity shrinkage porosity trend analysis
Test specimens block.
Background technology
In casting field of metallurgy, incline in order to the shrinkage porosity defect of contraction cavity of test analysis different type or different conditions molten iron is formed
Tropism, needs to pour into a mould a test specimens block, then checks sample block thermal center (-tre) nearby shrinkage cavity shrinkage porosity form and volume size.Used in the past
The test specimens block analyzed in molten iron shrinkage cavity shrinkage porosity is mostly the square block of simple shape, cylindrical block or " ten " cabinet frame type etc., this
A little test specimens blocks allow to install feeding head or core in casting process, not.Although this kind of analysis method is obtained in that molten iron
The information such as shrinkage porosity defect of contraction cavity formability size, but for feeding head effect and addition core are to shrinkage porosity defect of contraction cavity shape
Into impact it is unknown.In addition, in deeper step analysis, this kind of test specimens block casting type is also not easy to the inspection of installation volume effect
The sensor such as survey and thermocouple.
The content of the invention
The purpose of this utility model is：Overcome the deficiencies in the prior art, there is provided one kind is inclined for molten casting iron shrinkage cavity shrinkage porosity
To the test specimens block of analysis.Such test specimens block poured into a mould has can be while emit to shrinkage porosity defect of contraction cavity formability and addition
The characteristics of impact of mouth and core carries out comprehensive analysis, and expansion or linear movement pick-up can be installed in test specimens block casting type
And thermocouple researchs and analyses the interaction process that graphite and shrinkage depression are formed.
The purpose of above-mentioned utility model is realized by following technical scheme：
A kind of test specimens block for molten casting iron shrinkage cavity shrinkage porosity trend analysis, by the block 1 with different volumes modulus,
Block 2 and block 3 are sequentially connected in I-shaped, and block 2 has less bulk modulus and solidifies faster for a long narrow boards
Time, by the circulation blocking of the molten iron of block 1 and block 3 in process of setting, the bulk modulus of block 1 it is more slightly larger than block 2 and its
It is connected to manufacture shrinkage cavity shrinkage porosity formation condition, there is block 3 maximum bulk modulus to tend to form contracting after being connected with block 2
Hole shrinkage porosite, and the block casting mold surface or top be easily installed rising head implement feeding, or installation volume expansion or
Linear movement pick-up and thermocouple are used for graphite expansion and its Feeding Characteristics are tested and analyzed.
The beneficial effects of the utility model：Test specimens block structure of the present utility model is simple, can provide molten iron shrinkage cavity simultaneously
The information such as the impact of shrinkage defect formability size and installation feeding head effect and addition core.And can be with installation volume
The sensor such as effect detection and thermocouple, to carry out profound analysis.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is test specimens block structure schematic diagram of the present utility model.
1. part, 1 block, 2. part, 2 block, 3. part, 3 block in figure.
Specific embodiment
After now be described in specific embodiment of the utility model.It is referring to Fig. 1, in the present embodiment, a kind of to be used for casting ferrum
The test specimens block of water shrinkage cavity shrinkage porosity trend analysis includes：Block 1 with different volumes modulus, block 2 and block 3 are sequentially connected
In I-shaped, block 2 has less bulk modulus for a long narrow boards and setting time faster, by block in process of setting
The molten iron circulation blocking of body 1 and block 3, the bulk modulus of block 1 is more slightly larger than block 2 to be connected thereto for manufacturing shrinkage cavity shrinkage porosity shape
Into condition, there is block 3 maximum bulk modulus to tend to form shrinkage cavity shrinkage porosity after being connected with block 2, and cast in the block
Type surface or top are easily installed rising head and implement feeding, or installation volume expansion or linear movement pick-up and thermocouple are used
Test and analyze in graphite expansion and its Feeding Characteristics.
Claims (1)
1. a kind of test specimens block for molten casting iron shrinkage cavity shrinkage porosity trend analysis, is characterized in that：With different volumes modulus
