Problems solved by technology

At the same time, affected by various factors, the pressure fluctuation of the emulsion system is relatively large, and this pressure fluctuation is transmitted to the strip steel, which aggravates the tension instability of the strip steel
Therefore, the yield of extremely thin plate rolling is low and the cost is high

Abstract

The emulsion spraying method of maintaining stablity of sheet during continuous rolling features that emulsion is sprayed from the work roll gap lubricating beam A arranged in the entrance side of the frame to the roll gap between upper and lower work rolls in the lower pressure of 0.3-0.4 MPa, from the work roll cleaning and cooling spray beam B arranged in the exit side to the surface of upper and lower work rolls in the pressure of 0.5-0.7 MPa, from the intermediate roll and support roll cooling and cleaning spray beam D in the exit side to intermediate roll and support roll in the pressure of 0.8-0.9 MPa, and from the strip steel cooling and cleaning spray beam C in the exit side to the upper and lower surfaces of strip steel in the low pressure of 0.3-0.4 MPa. The method can raise the stability of the strip steel.

Description

technical field [0001] The invention belongs to the field of high-speed rolling of ultra-thin plates, and in particular relates to an emulsion injection method for ensuring the stability of strip steel in the process of continuous rolling of ultra-thin plates. Background technique [0002] The rolling speed of modern tandem cold rolling mills is generally between 1500m / min and 3000m / min. For tandem cold rolling mills that produce extremely thin plates, in terms of production efficiency, the normal production speed is higher than that of ordinary cold rolled plates. In the process of rolling extremely thin plates, under the action of various disturbance forces, the rolling mill is prone to treble or quintuple frequency flutter, which is transmitted to the connected racks through the tension between the racks, causing system vibration and resulting in strip thickness. Severely out of tolerance or even broken belt, damage equipment. Therefore, ensuring the stability of the str...
