This is type spectrometer designed to meet the smelting, metal fabrication and machining of user requirements. It aims to analyze the raw material’s and molten iron’s components. So then let each element meet the standard. C, Si, S, P, Cr, Mn are the five critical elements of the casting chrome grinding balls. Moreover, it can help you to get the results fast and quickly.
With full computer control of the entire digital spark source, using CCD detection technology and the unique vacuum chamber, which can accurately determine the non-metallic elements C, P, S, and various alloyed components, so that to achieve full spectrum analysis. The results of measurement are accuracy and excellent long-term stability.
Main Technical Data
JB-300B impact testing machine widely used to determine the impact resistance properties of the metal material under dynamic load, so that to determine the quality of materials under dynamic load condition action.
This machine is semi-automatic control testing machine, simple operation and high efficiency, swing , impact, put the electrical control. And can use the remaining energy for the next test preparation, especially for continuous impact test laboratory and a large number of impact testing of metallurgy, machinery manufacturing and other industries.
Technical Data:
Rockwell hardness tester adopts Rockwell measure principle, directly measure the Rockwell hardness. It has characteristics of structural rigidity, simple operation, the stability of showing the value and easy maintenance. It is widely used in the hard alloy, carbon steel, alloy steel, cast iron, nonferrous metals and other materials Rockwell hardness testing.
Function:

Technical Specifications
Another test about the casting grinding balls is to see the distribution of Martensite, Austenite, and Carbon water mixture. This process can look at the changes in the balls’ inner structure due to the heat treatment.
Metallographic pre-mill machine
M-2 type Double Desktop Dual Speed Metallographic pre-mill machine, is a wet grinder. It adopts variety of different size water-resistant sandpaper, to polish the all kinds of samples of metals and alloys. Using this pre-mill machine, On the one hand, mechanical polishing instead of manual operation so that to improve the efficiency of sample preparation. On the other hand, it can be completely removed heating traces on the surface which is produced during sample cutting, polished organization for further microscopic determination. It can help cut the balls to do the further test.
