The invention discloses a waste recycling process for automobile disassembling. A fixed base is included, a fourth supporting column is fixedly connected to the left side of the top of the fixed base,a breaking box is fixedly connected to the top of the fourth supporting column, the top of the breaking box communicates with a feeding baffle, the left side of the breaking box is fixedly connectedwith a fixed block, and the top of the fixed block is fixedly connected with a second motor. Through cooperative use of a first motor, a rust removal box, a rust remover storage box, a water pump, spraying holes, rotary nozzles, an inner ball pipe, a rotating groove, an outer ball pipe, a hard connecting pipe, a second gear and a fourth gear, the waste rust removal effect is achieved, rust on thewaste surface can be removed thoroughly, the condition that during recasting, the iron reduces the quality of the waste after recasting is avoided, the waste quality after recasting can be greatly improved, the application field of the waste after recasting is widened, the process creativeness is enhanced, the waste utilization rate is improved, and the process is suitable for being used and popularized.
