Regarding oil pollution and preventive measures:

The pollution sources of quenching oil include: external pollution, such as the oxide scale brought by the workpiece, the water leaked from the cooler, and other substances from the outside; self-pollution, which cannot be automatically discharged during use and remains in the oil Oxidation deterioration products; plus the remaining products after the reaction of foreign pollutants with quenching oil and its pollutants. The accumulation of internal and external pollutants will gradually change the color, transparency, viscosity, flash point, residual carbon and acid value of the oil. This change process is the deterioration process of the quenching oil. Among the effects of deterioration, the changes in the oil cooling characteristics and the deterioration of the brightness of the workpiece after quenching are largely related to the heat treatment effect of the workpiece. Changes in cooling characteristics often change the quenching hardness, quenching depth and deformation of the same workpiece.

According to different working conditions, different burners are used. For example, adjustable flame burners, flat flame burners, high-speed nozzles, self-preheating burners, low nitrogen oxide burners, and recently developed regenerative burners, provide a variety of advanced to adapt to the use of gas and diesel burner. The correct use of advanced burners can generally save energy by more than 5%. The flat flame burner is suitable for use in heating furnaces, and the high-speed burner is suitable for all kinds of heat treatment furnaces and heating furnaces. The self-preheating burner is a combustion device that combines a burner, a heat exchanger, and a smoke exhaust device. Suitable for various industrial furnaces such as heating, melting, heat treatment, etc.

Remove the original furnace lining heavy high-aluminum refractory bricks, use a new energy-saving and high-temperature resistant aluminum silicate ceramic refractory fiber folding block, and weld the folding fiber to the furnace wall. The folding block has heat storage, good insulation, less heat loss, and maintenance. Convenience and other advantages, compared with refractory lining, energy saving is 20%~30%.
