Embodiment 1
[0040] Get 10kg of alloy powder, including 3.2kg (32%) of high-carbon ferrochrome, 0.8kg (8%) of chromium carbide, 0.5kg (5%) of ferrosilicon, 1.0 kg (10%) of ferromanganese, 1.4kg (14%) of ferroboron %), TiB 2 Powder 1.8kg (18%), vanadium iron 0.4kg (4%), titanium iron 0.3kg (3%), fluorite powder 0.1kg (1%), sodium fluorosilicate 0.1kg (1%), the balance is Reduced iron powder. The particle size of the obtained powder is such that it can pass through a 60-mesh sieve. Put the various powders taken into the mixer and mix them for 20 minutes to obtain the high-hardness wear-resistant drug core powder.
[0041] Preparation of high-hardness wear-resistant flux-cored wire: refer to the accompanying drawings for the preparation process figure 1 , specifically: select 12×0.4 (12mm in width and 0.4mm in thickness) H08A cold-rolled steel strip. During the forming process of the steel strip, the uniformly mixed powder is added into the U-shaped H08A cold-rolled steel strip groove, an...

During the forming process of the steel strip, the uniformly mixed powder is added into the U-shaped H08A cold-rolled steel strip groove, an...
Embodiment 3
[0046] Get 10kg of alloy powder, including 3.4kg (34%) of high-carbon ferrochrome, 0.6kg (6%) of chromium carbide, 0.6kg (6%) of ferrosilicon, 1.2 kg (12%) of ferromanganese, 1.4kg (14%) of ferroboron %), TiB2 1.4kg (14%) powder, 0.3kg (3%) ferrovanadium, 0.6kg (6%) ferrotitanium, 0.1kg (1%) fluorite powder, 0.1kg (1%) sodium titanate, and the balance is reduction Iron powder. The particle size of the obtained powder is such that it can pass through a 60-mesh sieve. Put the various powders taken into the mixer and mix them for 20 minutes to obtain the high-hardness wear-resistant drug core powder.
[0047] Preparation of high-hardness wear-resistant flux-cored wire: refer to the accompanying drawings for the preparation process figure 1 , specifically: select 12×0.4 (12mm in width and 0.4mm in thickness) H08A cold-rolled steel strip. During the forming process of the steel strip, the uniformly mixed powder is added into the U-shaped H08A cold-rolled steel strip groove, and ...
