Description

Roller oxide removing device

Technical Field

The utility model relates to a roll production facility technical field, in particular to roll oxide remove device.

Background

Quenching is a heat treatment process in which steel is heated to a temperature above a critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), is kept warm for a period of time to make it fully or partially austenitized, and is then rapidly cooled to a temperature below Ms (or isothermal near Ms) at a cooling rate greater than the critical cooling rate to perform martensite (or bainite) transformation. After the differential temperature treatment roller is heated in the differential temperature furnace, the roller needs to be placed on a cooling machine for cooling, and due to material or process reasons, when part of the roller is cooled on the cooling machine, the roller body generates more oxide skin. Specifically, the oxide skin is a layer of diaphragm attached to the surface of the roller, the loose degree of the diaphragm is different, the thickness of the diaphragm is different, and the cooling speed of the surface of the roller is influenced, so that the uneven temperature reduction of the roller body temperature and the accuracy and temperature control of temperature measurement are influenced, and the surface hardness of the roller is influenced. Finally, the part which is loose and serious (the thickness of the diaphragm) after quenching is not hardened at all. In addition, the uneven surface hardness of the workpiece after quenching is caused by the different thicknesses of the diaphragms. Therefore, the oxide skin should be cleaned, the manual cleaning is time-consuming and labor-consuming, and the workpiece has high temperature and potential safety hazard. At present, an oxide removing device is also arranged, but the surface of the roller is easy to damage, needs to be fixed and is inconvenient to translate.
