Spectral sample grinding auxiliary device

The utility model relates to the technical field of steel production equipment, in particular to a spectrum sample grinding auxiliary device, which comprises a power supply and an electromagnet, a connecting mechanism capable of controlling the electromagnet to swing on the power supply is arranged between the electromagnet and the power supply, a coil is wound on the electromagnet, the coil is electrically connected with the power supply, and the power supply is connected with the electromagnet. When the spectrum sample grinding device is used, scrap iron flying into the air during spectrum sample grinding is cleaned through the electromagnet, workers only need to turn on a switch of a power source in the sample grinding process, the iron sheet protective cover of the spectrum sample grinding device is right opposite to the tail of sparks generated by sample grinding, the scrap iron is automatically attracted to the electromagnet, and the scrap iron can be automatically removed.
