摘要： A process is set forth for cold rolling of a metal strip, wherein the metal strip passes through a nip between two counter-rotating rolls, driven in counter-rotation substantially at room temperature, wherein a cold and/or liquefied gas, preferably an inert gas, is blown into the area of the nip or roll gap. A roll stand according to the present invention comprises two counter-rotating rolls forming a nip or rolling gap and nozzle means for blowing a cold and/or liquefied gas, preferably an inert gas, through at least one orifice of said nozzle means into the area of the roll nip. Preferably, the temperature of the cold and/or liquefied gas is appreciably lower than room temperature.

摘要： An apparatus and method for monitoring and/or controlling cryogenic cooling by measuring the opacity of the vapor cloud (113) generated from a cryogenic cooling device (112). The opacity is determined by measuring the reduction in intensity of a light beam (127) passed through the vapor cloud (113). The opacity measurements are used to control an operating parameter of the system, such as the cooling rate of the cryogenic cooling device (112). The opacity measurements may be normalized to compensate for variables, other than temperature of the workpiece (119) and cooling rate, which may affect the opacity of the vapor cloud (113).
摘要翻译： 一种用于通过测量由低温冷却装置（112）产生的蒸汽云（113）的不透明度来监测和/或控制低温冷却的装置和方法。 通过测量通过蒸气云（113）的光束（127）的强度的降低来确定不透明度。 不透明度测量用于控制系统的操作参数，例如低温冷却装置（112）的冷却速率。 不透明度测量可以归一化以补偿除了工件温度（119）和冷却速率之外的变量，这可能影响蒸气云（113）的不透明度。
