Step 2: Heat the surface of the base material, until the temperature of the wire to the operating temperature of 380℃～400℃, so you can rely on the parent metal heat transfer welding wire to form welds, should not use the flame to burn wire, When the surface temperature of the base metal is sufficient, the wire can flow well and penetrate into the metal capillary. Step 3: When repairing thin aluminum, as long as the aluminum base metal heated to the appropriate working temperature, and then use the wire back and forth friction melting to form a weld, only with a metal brush melt welding wire to weld at the weld. Step 4: Use propane gas to weld s mall object, use industrial gas or induction heating device to heat and weld big object, natural slow cooling after welding. Application in Life: Can be used for a variety of

high-density graphite crucible so that the crucible has the best thermal conductivity, thermal conductivity better than other imported crucible; the graphite crucible and the appearance of a special glaze layer and forming a dense material, greatly improving the corrosion resistance and prolong its service life; the graphite crucible graphite component used in all natural graphite, thermal conductivity is very good. After heating the graphite crucible can not be immediately placed on a cold metal table, due to a sharp cooling in order to avoid it being broken. Mainly used in the purification of gold and silver smelting, metal casting special, university experimental equipment, acid corrosion of the crucible, the crucible temperature analysis, small scale casting, special alloy smelting casting mold and so on.
