碳弧气刨也叫电弧气刨(以下简称气刨)是利用特制的碳棒,在电焊机电流作用下,产生约3000℃以上的电弧。这种电弧把金属加热到熔化状态,在液体金属凝固之前,用4～6公斤/厘米~2的压缩气流,把液体金属吹走,达到“刨削”的目的。由于气刨可以用宋代替风铲剔除铸件上的毛刺,刨削残留在冒口根部的冒口茬,修整铸件表面 Carbon arc gouging, also known as arc gouging (hereinafter referred to as gouging) is the use of special carbon rods, welding current, resulting in about 3000 ℃ arc. This electric arc heats the metal to the molten state. Before the liquid metal solidifies, the liquid metal is blown away with a compressed air flow of 4 to 6 kg / cm 2 to achieve the purpose of “planing”. As the gouging can be used to replace the wind blade shovel castings on the glitches, shaving the riser stubble in the riser root, trim casting surface
