Embodiment 1
[0061] see figure 1 , the molten metal splash test method of embodiment one of the present invention, described molten metal splash test method comprises the following steps:
[0062] S1, heating the iron wire into molten droplets;
[0063] S2. Detecting each droplet before the droplet falls into the guide groove to obtain the quantity of the droplet;
[0064] S3. After the droplet flows through the guide groove, it impacts the sample and falls into the droplet collection container, and the temperature sensor detects the temperature of the sample;
[0065] S4. Calculate the mass difference of the droplet collection container to obtain the droplet mass;
[0066] S5. When it is detected that the temperature of the sample has risen by 40K, stop the test and record relevant data, and the detection of a single sample is completed;
[0067] S6. Repeat the foregoing steps 10 times to obtain relevant data of 10 samples.

Embodiment 2
[0071] The difference between the second embodiment and the first embodiment is that the process is limited.
[0072] see Figure 3 to Figure 7 , a kind of molten metal splash tester for realizing the molten metal splash test method of the present invention, described molten metal splash tester comprises:
[0073] Rack 1;
[0074] Droplet generating device 2, said droplet generating device 2 is arranged on the frame 1, said droplet generating device 2 includes a wire feeding mechanism 21 for automatically conveying iron wire and a combustion mechanism for heating the iron wire to molten droplets twenty two;
[0075] A droplet guiding mechanism 4, the droplet guiding mechanism 4 is arranged on the frame 1, and the droplet guiding mechanism 4 includes a guide groove 41;
[0076] Sample temperature measuring device 5, the sample temperature measuring device 5 is arranged on the frame 1;
[0077] A droplet collecting device 6, the droplet collecting device 6 is arranged on the...
example 1
[0113] Example 1: First, install sample 0410 (a thinner sample) on the sample hook, hang a weight on the other end, adjust the front and rear positions of the temperature sensor 52, and make the distance between the funnel mouth of the guide groove 41 and the sample be about 1.5mm about. Remove the sample, turn on the laser generator 72, aim the laser emitting head at the guide groove 41, and make the laser guide groove 41 shoot out from the funnel mouth and irradiate the temperature sensor 52. Adjust the temperature sensor 52 up and down, left and right adjustment knobs, so that the position of the laser mark is just in the center of the temperature sensor 52 . Turn off the laser transmitter and remove the laser transmitter head. Reload the sample. Adjust the distance between the burner 224 and the center of the iron wire to about 10mm. Turn on the host computer, input the linear density of iron wire used as 0.6228g / cm, and input the flow rate of acetylene as 0.12m 3 / h. ...
