摘要： PROBLEM TO BE SOLVED: To uniformalize a flow rate distribution in the longitudinal direction, and to facilitate maintenance by building in a lamina header pipe interior flow rate distribution uniformalizing swash plate. SOLUTION: When inserting a lamina header pipe interior flow rate distribution uniformalizing swash plate into a lamina header 1, the cross-sectional area of the flow passage of cooling water in the lamina header 1 is wide on a flow-in side, and is narrow at an end cover 3 end. The flow rate distribution uniformalizing swash plate is formed so that the change rate of the cross-sectional area of this lamina header is equal to the change rate of the sum of a pressure loss by pipe friction resistance in the lamina header in each lamina nozzle 2 position and a flow rate loss head. Consequently, the internal pressure head of the lamina nozzle part becomes equal at each portion in the longitudinal direction of the lamina header 1, the water injection flow of each lamina nozzle 2 becomes constant, and a flow rate distribution in the longitudinal direction of the lamina header 1 can be uniformalized.

摘要： PURPOSE:To carry out hot rolling excellent in lubricity by providing a device to supply hot lubricant wherein solid lubricant, heat insulating agent, etc., are mixed with semisolid lubricant, a nozzle having a specific shape and a pump to forcedly feed the lubricant and accumulator. CONSTITUTION:Lubricant 2 which specified amounts of solid lubricant, heat insulating agent, extreme pressure agent are dispersed uniformly in semisolid lubricant at a specified ratio is stored in a tank 1. The lubricant 2 is fed forcedly by a reciprocating pump and the pulsation of the lubricant 2 sprayed by an accumulator 7 from a spray nozzle 6 is prevented. The nozzle 6 mixes and atomizes the lubricant 2 and atomizing air in an orifice 22 and since the opening of the orifice 22 is slit laterally, a wide angle spraying is carried out and painting can be carried out at uniform flow in the length direction of work rolls. Consequently, the flow distribution in the width direction can be uniformized and the flow of the lubricant can be reduced to perform stable lubrication rolling.
