Examples
Example Embodiment
[0016] The ferromanganese powder described in Example 2 is medium-carbon ferromanganese powder with a carbon content of 1.2%; the carbonate powder is magnesium carbonate powder.
Example Embodiment
[0017] The ferromanganese powder described in Example 3 is a medium-carbon ferromanganese powder with a carbon content of 1.0%; the carbonate powder is calcium carbonate powder, magnesium carbonate powder, and barium carbonate powder, and the weight ratio of the three is 3. : 2:5.
Example Embodiment
[0018] Example 1
[0019] According to the weight part of the carbon steel electrode coating in Example 1 in Table 1, add the coating to the mixer as required, then mix with water glass binder, stir and mix evenly, and then add it to the special electrode coating machine for coating After the carbon steel welding core, it enters the dryer to dry and finalize the shape, and finally, after inspection and packaging, various carbon steel electrodes of different specifications are made.
[0020] Example 2
[0021] According to the distribution ratio of the carbon steel electrode coating in parts by weight in Example 2 in Table 1, other processes are the same as in Example 1, and will not be repeated.
[0022] Example 3
[0023] According to the distribution ratio of the carbon steel electrode coating in Example 3 by weight in Table 1, the other processes are the same as in Example 1, and will not be repeated.
