    • The present invention relates to a steel plate conveyor roller apparatus for a soaking pit without a cooling device. The purpose of the present invention is to improve the structure of the conveyor roller installed with an ability to rotate in order to convey a steel plate to a soaking pit of a high temperature in such a way that the conveyor roller can resist the high temperature without the cooling device for cooling the conveyor roller, so that maintenance is convenient and a heat loss inside the soaking pit can be prevented. The conveyor roller apparatus comprises a connecting shaft provided at both ends of the soaking pit to be exposed outside the soaking pit by each end being connected to a driving force transfer part configured to transfer a driving force of a driving motor; a hollow tube formed to be exposed outside the soaking pit by inserting each of the other ends of the connecting shaft into an inner side of one end and being fixed by welding; an axle part each formed by a composition including Cr, Ni, and W to prevent the shape from being changed at high temperatures; a hollow cylindrical body installed inside the soaking pit to partially expose both ends outside the soaking pit by inserting each of the other ends of the axle part into an inner side of one end and the other end and being fixed by welding; and a shell part formed by a composition including Cr, Ni, and W to prevent the shape from being changed at high temperatures.
    • 本发明涉及一种没有冷却装置的均热槽钢板输送辊装置。 本发明的目的是改进安装有转动能力的输送辊的结构,以便将钢板输送到高温的均热槽,使得输送辊能抵抗高温而没有 用于冷却输送辊的冷却装置,使得维护方便,并且可以防止在均热槽内的热损失。 输送辊装置包括:连接轴,其设置在浸泡坑的两端,暴露在均热槽的外部,每个端部连接到构造成传递驱动电动机的驱动力的驱动力传递部; 通过将连接轴的另一端插入一端的内侧并通过焊接固定而形成为暴露在浸泡​​坑外部的中空管; 每个由包含Cr,Ni和W的组合物形成的轴部,以防止在高温下形状变化; 通过将轴部的另一端插入一端和另一端的内侧并通过焊接固定来安装在均热槽内部的中空圆柱体,以将两端的一部分露出浸泡凹坑内部; 以及由包含Cr,Ni和W的组合物形成的壳部,以防止在高温下形状变化。
