B. with the weighed probe raw material compaction moulding in the mould of packing into;
C. take out probe, under room temperature environment after the drying, probe head was immersed in the phosphoric acid 3 to 4 minutes fully;
D. after treating pickling probe bone dry, it is carried out high-temperature firing.
Described probe for quick tester of hydrogen content in aluminium alloy fusant manufacturing approach; High-temperature firing described in the steps d is that probe is heated to 300 ℃ from room temperature in stove, is incubated after 30 minutes, continues to be warmed up to 800 ℃; Be incubated 30 minutes again, cool to 200 ℃ then with the furnace.
A kind of probe for quick tester of hydrogen content in aluminium alloy fusant that utilizes above-mentioned method to make, described probe comprises the head of phosphate impregnation, and described head connects sonde body, and described probe and sonde body are through high-temperature firing.
The described probe for quick tester of hydrogen content in aluminium alloy fusant that utilizes, described high-temperature firing are that probe is heated to 300 ℃ from room temperature in stove, are incubated after 30 minutes, continue to be warmed up to 800 ℃, are incubated 30 minutes again, cool to 200 ℃ then with the furnace.
Beneficial effect of the present invention:
1, the used material silit of the present invention, bentonitic clay, water, alumina powder, cupric oxide powder, gesso etc. all no longer produce gas behind high-temperature firing; And can effectively intercept alloy melt after mixing each other; And make probe have gas penetration potential and very high hot strength preferably; Factor of porosity moderate (not metallic cementation liquid, permeability is good) can satisfy the technical requirement of metal bath hydrogen content fast measuring device fully.
2, technology is simple, is convenient to processing, and yield rate is high.
3, with low cost, to compare with dedicated probe that import instrument is joined, cost reduces more than 90%.
4. the detecting head surface hardenability is improved significantly after phosphoric acid is handled
5. behind high temperature ablation, residual volatile matter is able to remove fully in the probe.
