The invention discloses a material for sealing a cathode steel bar of an aluminum electrolytic tank, which is prepared by mixing refractory particles, mixture of aluminum oxide powder and a refractory material, a binding agent and water according to a certain proportion, wherein the refractory particles account for 30-60% by weight, the mixture of the aluminum oxide powder and the refractory material accounts for 25-55% by weight, the binding agent accounts for 5-18% by weight and the water accounts for 7-15% by weight; the refractory particles adopt aluminum silicate particles or silicon oxide particles, and the binding agent adopts high aluminum cement or water glass; the required materials are poured into a stirring machine according to the proportion during the production, the stirring is firstly carried out for 3-5min for uniformly mixing and stirring the added materials, then an appropriate amount of the water is added for stirring for 5-10min, the stirring is stopped after confirming that the stirred materials have good flowability through visual observation, and then the materials are pouring into a container for preparation; and the material has simple production, good self-flowing property, convenient construction, good sealing performance and high temperature resistance.

The invention discloses a real-time online monitoring system for the health state of a fixed winch hoist. The real-time online monitoring system comprises a stress-strain monitoring system, a flow-induced vibration monitoring system, a starting and stopping force monitoring system, a signal transmission system, a signal acquisition system, a monitoring system, an early warning system, a data system, a PC system and a central control room. The system is accurate and reliable in monitoring data, can guarantee that the operation of the metal structure equipment of the fixed winch hoist is in real-time on-line visual observation and monitoring, enables related workers to master the health state of the equipment at any time, facilitates the long-term safe operation of the equipment, formulatescorrect corresponding detection and maintenance schemes, and save a lot of manpower, material resources and financial resources, and provides a basis for redesign, manufacturing, inspection, installation and the like of the equipment through real-time online health state monitoring data.
