Mixed solution supply device for rolling equipment

Abstract

The invention relates to a mixed solution supply device for rolling equipment. In the rolling equipment including a plurality of stands with having a pair of rolls, a mixed solution supply device for supplying a mixed solution to the rolls. The mixed solution supply device includes: a main water supply line and a first flow regulating valve, both of which are arranged in a plurality of water supply lines branched from the main water supply line and distributed to a plurality of brackets, and the flow rate of the water flowing in the plurality of water supply lines is adjusted so that the flow rate of the water flowing in the plurality of water supply lines is uniform with each other; multiple oil supply lines allocated to multiple water supply lines; and second flow regulating valves arranged in a mixed line branching from the water supply lines and a fuel supply line and distributed to the upper line and the lower line of the upper and lower parts of the corresponding brackets and adjust the flow rate of the mixed solution flowing in the upper nozzle and the lower nozzle so that flow rates of the mixed solution flowing in the upper spray head and the lower spray head are uniform with each other.

Description

technical field [0001] The present invention relates to a mixed solution supply device for rolling equipment, the mixed solution supply device of the rolling equipment by controlling the concentration of the mixed solution formed of water and oil and its width direction The injection flow rate can realize different injection modes according to the rolling process conditions, and can reduce the surface defects of the locally generated products. Background technique [0002] In general, high rolling loads during rolling have adverse effects on the design life and durability of rolling equipment. In order to reduce this load, lubricated rolling in which a mixed solution of cooling water and rolling oil is sprayed and mixed to reduce the frictional force between the roll and the steel plate is performed during rolling. [0003] In particular, in the case of surface-sensitive stainless steel, a surface defect called sticking, in which the skin layer peels off due to the sticking...

Problems solved by technology

[0004] When spraying this mixed solution, if you do not respond in the width direction of the steel plate according to the rolling process conditions, slippage will occur and the entire line may be interrupted
