A hot rolling lubrication simulation testing machine comprises a water tank, a water route and a water pump, wherein an oil tank, a water pump, a metering pump, a water inlet and a backflow opening are arranged on the water tank. An oil filling opening and an oil return opening are arranged on the oil tank, an oil outlet route, an oil release opening and an oil tank liquid level device are arranged on the side face of the oil tank, the oil route is connected with the metering pump, and a branch oil route backflow pipe is arranged at an outlet of the metering pump. An inlet of the water pump is connected with the water inlet, an outlet of the water pump is connected with a water pipeline, and a flowmeter and a static mixer are arranged on the water route. The oil route is connected with the static mixer which is connected with an outlet of the static mixer by a flange. The backflow pipeline is arranged on the water route, and a backflow valve is arranged on the backflow pipeline, and an electrical device control cabinet and a water tank liquid level device are arranged beside the water tank. The hot rolling lubrication simulation testing machine is reasonable in structure, is applied to development and evaluation of hot rolling lubricating oil products in a lubricating oil industry or site application of hot rolling process lubrication in a metallurgical industry, and thus inspects applicability of oil products under an actual site condition.
