Sealing protection device for vacuum induction furnace

Abstract

The invention provides a vacuum induction furnace sealing protection device, the vacuum induction furnace comprises a furnace body and a furnace cover, the furnace cover covers the furnace body, the upper edge of the furnace body is provided with a sealing ring, and the furnace body and the furnace cover are pressed and sealed through the sealing ring; a protection plate is arranged on the inner side of the joint of the furnace body and the furnace cover. According to the sealing protection device, the protection plate is arranged on the inner side of the joint between the furnace body and the furnace cover of the vacuum induction furnace, molten steel splashing in the smelting process of a smelting chamber crucible is shielded through the protection plate, the molten steel cannot be splashed to the position of the sealing ring, the phenomenon that the sealing contact face of the sealing ring is ablated is prevented, the frequency of replacing the sealing ring is reduced, and the service life of the sealing ring is prolonged. And the sealing reliability of the furnace cover and the furnace body is ensured. The sealing protection device is simple in structure, convenient to install and high in safety and reliability, and the maintenance cost of the sealing ring is greatly reduced.

Description

technical field [0001] The invention relates to the field of vacuum induction furnace sealing protection, in particular to a vacuum induction furnace sealing protection device. Background technique [0002] The vacuum induction furnace is generally composed of a furnace shell, an induction furnace body, a tilting furnace mechanism, an ingot mold mechanism, a power supply device, and a water cooling system. The furnace shell is equipped with observation, temperature measurement, feeding, sampling and other devices. The furnace is equipped with vacuum system, power supply system and control system. In the metallurgical industry, it is used to smelt the alloys and special steels required by the aerospace, missile, rocket, nuclear and electronic industries, and the vacuum degree of the vacuum induction furnace is extremely high. In the vacuum smelting process, due to the need to stir the molten steel in the crucible, the molten steel will splash outward and splash to the seali...

AI Technical Summary

Problems solved by technology

In the vacuum smelting process, due to the need to stir the molten steel in the crucible, the molten steel will splash outwards and splash to the sealing part of the furnace cover and the furnace body, which will easily burn the rubber seal and damage the sealing surface of the furnace cover. The smoothness reduces the vacuum degree of smelting and cannot meet the smelting requirements, resulting in abnormal consumption of sealing materials and unqualified scrapping of special steel products

When pouring steel at the end of smelting, because the personnel cannot grasp the best steel pouring speed and timing, pouring steel too quickly will cause molten steel to splash, resulting in damage to the chamber seal; it is very difficult and time-consuming to clean the steel slag, and the replacement of the seal is time-consuming and expensive expensive
