Definitions
- the lubrication efficiency is a function of the rolling temperature, the nature of the lubricant (mineral, ester-based, etc.) and the amount thereof.
- Satisfactory results are obtained by spraying oil in surface densities ("plate-out") of 0.1 to 1 g / m 2 , which is significantly more than is required simply to control the degradation of the rollers .
- the present invention aims to provide a solution that overcomes the drawbacks of the state of the art such as the impossibility of controlling and controlling the concentration and stability of the oil-water emulsion, the plugging of the intake pipes emulsion by formation of solid organic residues, the influence of the specific flow rate, etc.
- the invention also aims to increase the homogenization of the distribution of the oil on the cylinders.
- the installation of the invention is provided with means for controlling the temperature of the box, preferably comprising an electrical resistance or a water circuit.
- the temperature control provides better controllability of the process in general and in particular reduces the problems related to the viscosity of the lubricant.
- the installation comprises a plurality of nozzles or injectors or atomizers distributed over the width of the rolling line, some of which may be made non-operational to adapt to the effective width of the strip and / or the surface quantity of the strip. lubricant to be deposited.
- the internal side walls of the box may be covered with a common material 5 or alternatively with a material 5 allowing the suction of the lubricant, as shown in FIG. figure 4 .
