An improved roller cooling and gap lubrication device, an improved roller cooling and gap lubrication device, belongs to the technical field of rolling mills. Used to solve the use defects of existing devices such as uneven lubricating oil film and easy mixing with residual cooling water. The composition includes upper and lower water cutting plates located at the entrance of the roller gap, cooling headers arranged above and below the upper and lower water cutting plates, and lubrication headers arranged at the upper and lower water cutting plates. The improvement is that the lubrication headers are arranged above the upper water cutting plate and below the lower water cutting plate. The utility model can enable the uneven lubricating oil sprayed onto the roller surface by the lubrication header to be scraped off by the upper and lower water cutting plates, thereby forming a uniform oil film; It can keep the lubrication header away from the high-temperature rolled parts between the roller gaps, and eliminate the scaling and blocking phenomenon of the oil spray nozzle caused by high-temperature baking; It can significantly improve the lubrication effect of the roller gap, thereby improving the surface quality of rolled pieces, especially plate and strip rolled pieces, and enhancing the service life of the roller; Suitable for installation and use on rolling mills, especially finishing mills in hot rolling of plates and strips.

A laser nano ceramic alloying process for the surface of a metallurgical hot roller, and a method for laser nano ceramic alloying for the surface of a metallurgical hot roller, characterized in that it includes the following process: machining the roller to remove the surface fatigue layer, obtain the required size and shape, and then grinding the surface to be irradiated by the excitation light, removing oil stains, and appropriate cleaning; Mix the nano carbide ceramic coating evenly with a phenolic resin adhesive, and then evenly coat the pretreated roller surface with a pre coating thickness of 0.01 to 0.05 mm, and then air dry it; Select high power CO2

The improved nickel-chromium-molybdenum infinitely chilled cast iron and composite roller are related to the improvement of the roll material nickel-chromium-molybdenum infinitely chilled cast iron for metal processing, hot rolled and cold rolled plates and strips. In particular, they relate to a nickel-chromium-molybdenum infinitely chilled cast iron with good wear resistance and thermal crack resistance, and long service life, characterized by the addition of 0.03-0.1% boron and 0.2-1.5% niobium to the nickel-chromium-molybdenum infinitely chilled cast iron component. And a composite roller made of this material. Due to the addition of boron and niobium, the wear resistance and thermal crack resistance of the material have been significantly improved, overcoming the shortcomings of raw materials. The service life of the composite roller made of this material as a working layer is greatly improved compared to the original one, which can increase the rolling amount of the plate and strip by more than 20%; The improvement of heat crack resistance significantly reduces the number of times to stop and change rollers for repair, not only reducing the labor intensity of operation, but also improving the operation rate of the rolling mill and increasing the rolling output during shift hours.
