stainless steel hot rolled steel plate is a kind of stainless steel plate produced by hot rolling process. Those with a thickness of no more than 3mm are thin plates, and those with a thickness of more than 3mm are thick plates. They are used to manufacture corrosion-resistant parts, containers and equipment in chemical, petroleum, machinery, shipbuilding and other industries. Usually, the hot rolling lubricant is sent to the roll surface in the form of oil-water mixture. Water is the carrier, and a small amount of oil is evenly dispersed in water. The action process of oil-water mixture is the transformation process from oil in water phase to water in oil phase. After the mixed liquid reaches the roll surface, it expands rapidly on the roll surface in the form of oil in water. When it enters the deformation zone and contacts with the high-temperature rolled piece, due to the action of temperature and pressure, the water evaporates quickly and changes into the water in oil phase, and part of the oil burns into combustion products dominated by ash; Part of the oil is evenly covered on the contact arc surface between the roll and the rolled piece in the form of oil film, and both of them can play the role of lubrication within about 0.01s in the deformation zone.
