1, raw materials testing (ingredients before detection)

Sampling methods: a barrel sampling, get 10 points of samples in the iron drum of material by sampling tube, to do testing respectively

Test items: chemical composition (including moisture, Fe, S, K, Na, Ca, Ni, Co and other trace elements detected), and particle size

2, The detection after the ingredients (mixed powder after mixing)

3, The detection after the ingredients  (mixed powder into the graphite ware before pressure)

Test items:  Check whether it have been pressing or not with naked eye, and if there are impurities in the material surface.

4, after sintering carbonized test ( test the titanium carbide caking after carbonized)

Test items: Check the ware surface whether there are impurities, checking whether the massive cross-section of titanium carbide uniform color, were observed with the naked eye.

5, the detection after milling crushing (detection of titanium carbide powder after milling crushing )

Test items: Chemical composition

6, Detection after sieving  (detection the titanium carbide after the sieving, test the titanium carbide powder)

Test items: Chemical composition

7, mixed batch of finished products after testing (to detect titanium carbide together after batch testing of finished titanium carbide powder）

Test items: Chemical composition

Note: each small batch is 200 kgs, After 1000 kg ( 5 batch）mixing

8,The detection of qualified, labeling, packaging, delivery!
