Embodiment

[0015] See figure 1 , the upper and lower nozzles 2 and 5 are respectively fixed at the beams 3 and 4 of the upper and lower rolls of the UF rolling mill, and two fan-shaped water nozzles are respectively arranged on the upper and lower nozzles 2 and 5, and the fan-shaped water nozzles connect the upper and lower rolls 1 and 6 Full coverage, in order to achieve the purpose of full hole spray.

[0016] The on-site net ring water pipeline is used for water supply, and the flow control valve controls the water flow; the raw liquid adopts the pump motor frequency conversion speed regulation method, and the raw liquid flow is controlled by controlling the motor speed.

[0017] The raw liquid and water are mixed in a mixer to form a lubricating liquid of a certain concentration, and the lubricating liquid is sprayed onto the surfaces of the upper and lower rolls 1 and 6 through fan-shaped water nozzles to achieve the purpose of lubricating the profile 7.

[0018] Set the formula ac...

Abstract

The invention relates to a lubricating method for sectional material rolling. Lubricating fluid is used for lubricating a roller by adopting a full-hole type lubricating method through a nozzle. The volume percentage concentration of the lubricating fluid is in the range of 3% to 11%; the flow range of the lubricating liquid is 0.8 to 1.2m<3> / h; the pressure range of the lubricating fluid is 3-6 kilogram force; and athe relationship among the rolling speed of a sectional material, the volume percentage concentration of the lubricating liquid and the injection flow is as shown in specifications. The lubricating method has the advantages that the surface quality of the product is improved, and the roll consumption and power consumption are reduced; the adhesion of iron sheets on a roller isreduced; the rolling rhythm is improved; and the productivity is improved.

Description

technical field [0001] The invention belongs to the field of profile rolling, in particular to a lubricating method for profile rolling. Background technique [0002] At present, lubricated rolling technology is widely used in the field of hot strip steel and cold rolling. The benefits are: 1. Reduce the friction coefficient between the roll and the rolling piece during the rolling process, reducing power consumption; 2. Reduce rolling force ; 3. Reduce the consumption of rolls and increase the operating rate; 4. Improve the surface quality of rolled products, etc. However, the lubricated rolling technology has not been maturely applied in the rolling of profiles. The reason is that the deformation of the profiles is complicated after the lubrication technology is adopted in the rolling process. There are many factors affecting the lubrication effect, and it is difficult to control the product size specifications. Contents of the invention [0003] In order to overcome th...
