Attention and emergency measures for industrial furnace failure

Prepare operation procedures for use and maintenance, establish operation records and repair files, count the accumulated working hours of operation, strengthen daily maintenance, master the trend of equipment technical status change, find out the damage of the fault as soon as possible, avoid the hot repair of the nature of emergency repair, and prepare repair materials and prepare repair process in advance according to the load and working condition of electric furnace. For example, the service life of alloy elements is related to many factors such as working temperature, medium in furnace, quality and operation of elements, and its fluctuation life is 6000-10000h.

Generally, industrial furnaces have more leakage faults in spring and autumn season, and leakage faults are easy to occur when they are idle for a long time. The pressure rise rate of our factory is once a month (under normal temperature, close all vacuum valves, stop the vacuum system operation, read one number after 1 min, and read one number after one hour. The difference between the two numbers is the value of the pressure rise rate), and master the trend of equipment leakage change. For example, if the vacuum equipment is shut down for a week continuously, it is necessary to rotate by air once.

In the process of leak detection in industrial furnace system, besides plugging with mud paste, the leakage point suspected by the ether sword can be absorbed by medical needle tube to observe whether the vacuum meter reading changes. It can also make blind plate with vacuum silicon pipe hole, block vacuum pipe in sections and conduct leakage detection. The carbon deposit in diffusion pump can be cleaned by chemical pickling.
