Description
Technical field
The present invention relates to casting technology fields, specifically cast iron, cast steel Foundry Production in, one kind is adapted to
Before being poured on site, the method for quick Fabrication inspection nitrogen sample.
Background technique
With the progress of science and the reinforcement of environmental consciousness, nitrogen obtains all the more widely answering in casting field of metallurgy
With, while the continuous intensification that people recognize in terms of nitrogen is on cast iron and steel material property influence.The member of nitrogen contained in material
Cellulose content in a certain range when, the performance of material can be promoted, but after being more than a certain specific amount, product will appear very much
Negative issue, such as nitrogen pore, an inappropriate amount of nitrogen element content will lead to product batch and scrap.
Currently, more commonly examining there are two types of nitrogen modes in production, one is the methods examined using spectroscopy mode, but deposit
Essence is unable to reach for certain productions for needing keyholed back plate nitrogen content in the problem that the nitrogen component deviation of detection is larger
The requirement of quasi- production；Another kind is the method detected using oxygen-nitrogen analyzer or oxygen nitrogen hydrogen analyzer, the advantages of this method
It is that more can accurately detect nitrogen content, meets the requirement precisely produced.But the detection method is more demanding to sample, needs
The sample that steel or iron liquid casting go out is worked into a certain size, can be detected.Since sample manufacturing cycle is longer, this method can not
Meet the requirement that nitrogen content is quickly detected in production scene.
The production method of existing inspection nitrogen sample are as follows: Smelting of iron is completed, and after reaching certain temperature, part is taken out of furnace
Iron liquid casting is into mold, after waiting iron liquid to naturally cool to normal temperature state, unpacks and takes out first sample, then by the beginning of lathe process
Sample obtains the sample of a certain size requirement.Sample size is generally diameter≤5mm, and weight is in 1g or so.Existing inspection nitrogen sample
Time required for manufacturing process is generally higher than 1h, and it is too long that too long sample making course leads to entirely to examine the nitrogen time, can not adapt to give birth to
The requirement of production.
Summary of the invention
For existing oxygen-nitrogen analyzer or oxygen nitrogen hydrogen analyzer method for making sample, the technical problem to be solved by the present invention is to
How to be realized in production scene and quickly detect nitrogen component, meets the requirement of production scene.It is quick to provide a kind of production scene
Detect the method for making sample of nitrogen component.
The technical scheme is that providing the method for making sample that nitrogen component is quickly detected in a kind of production scene, including as follows
Step:
(1) melt iron for obtaining production cast iron controls molten iron temperature between 1350-1400 DEG C, takes iron liquid quick
It is poured into the special metal type mold of inspection nitrogen；
(2) it after natural cooling 2-3 minutes, unpacks and takes out sample, rapid water cooling to room temperature；
(3) sample for selecting suitable size cleans surface using alcoholic solution, the oxide layer on surface is washed, with blowing
Blower quickly dries up, and completes the production of inspection nitrogen sample.
Compared with prior art, the beneficial effects of the present invention are:
Inspection nitrogen sample is made using this method, the production of sample can be quickly completed, and for examining, realizes production scene
Stokehold quickly examine nitrogen, the promotion of stability contorting and production efficiency to production technology has positive effect.
The major measure of quick Fabrication inspection nitrogen sample has:
1, after the completion of cast iron melting, a small amount of molten iron is taken directly to pour into inspection nitrogen sample, without pouring into other samples
After cooling again by machine tooling at inspection nitrogen sample.
2, in such a way that metal shape casting mould and water cooling combine, cooling velocity is very fast.
3, after removing surface oxide layer with alcoholic solution, examination is can be obtained after drying rapidly in the sample for selecting suitable size
Sample.
Inspection nitrogen sample is made using this method, can quickly and easily complete the production of sample, and for examining, realizes life
Nitrogen is quickly examined in the stokehold for producing scene, to the stability contorting of production technology, there is positive effect.
