Abstract
The utility model relates to the protective field of a vacuum smelting furnace, which is a vacuum sealing protector specially suitable for vacuum inductance furnaces. The device is formed like that a lower port of a vacuum furnace cover of the vacuum smelting furnace is imbedded with a vacuum sealing ring which is tightly pressed to seal by a vacuum furnace body, and a smelting pot is installed in the vacuum furnace body. The device is characterized in that the inside part of the vacuum furnace cover is provided with at least one piece or a plurality of pieces of folding type iron guard sheets, and a lower end of the length of each guard sheet is lower than a sealing port of the vacuum furnace body. Compared with the prior art, the device can obviously improve the service life of the vacuum sealing ring and prevent the ablation phenomenon of the sealing port.
Description
The utility model belongs to the protection field of vacuum melting furnace.Be specially adapted to the protection ablation device of vaccum sensitive stove fire door sealing ring.
The vaccum seal ring of vacuum drying oven is the vitals of this equipment, and in the vacuum metling process, owing to there is very big electromagnetic stirring force to stir molten steel, make molten steel tend to be splashed to body of heater and bell binding site, be easy to the surface of this joint portion light knot of meeting ablation like this, and scorch the vacuum rubber sealing ring, make that smelting vacuum reduces, so that product rejection.When smelting, the sputter of molten steel is inevitably, so operating personnel before the steel smelting of every stove, all will clear up the slag that is ejected very difficulty and time-consuming, especially the manufacturing process complexity of this vaccum seal ring, and costs an arm and a leg.
This practical purpose is to propose a kind of simple in structure, economic vacuum-packed protector of vacuum drying oven fire door.
According to the utility model purpose, the solution that we proposed is to be equipped with anti-molten steel sputter baffle plate at the vacuum seal position of vacuum melting furnace, the slag that splashes can not be splashed down at the vacuum seal binding site, ablated to prevent that vaccum seal ring from being scorched with the fire door place.Be described in detail with reference to the accompanying drawings below.This accompanying drawing is the structural profile schematic diagram of the utility model vacuum drying oven furnace sealing protector, and in the accompanying drawings, 1 is the smelting furnace crucible, and 2 is the vacuum drying oven body of heater, and 3 is the vacuum rubber sealing ring, and 4 is the vacuum bell, and 5 is the fold-type steel panel.The composition of this vacuum melting furnace is to stud with vacuum rubber sealing ring 3 at the lower port place of bell 4, and compress sealing with vacuum drying oven body of heater 2, melting kettle 1 is housed in vacuum drying oven body of heater 2, it is characterized in that along the circumferential direction being equipped with the polylith fold-type steel panel 5 more than one or in the inboard of vacuum bell 4, the length of fold-type steel panel 5 is that the lower end should be lower than the furnace sealing port, the lower end of fold-type steel panel 5 length just, should be below sealed port, along the body of heater circumferencial direction, can block the slag that sputters in the melting kettle 1, make slag can not be splashed to the sealed port place.But the length of fold-type steel panel 5 is unsuitable long or too short; if fold-type backplate 5 length are long; when opening bell 4, break body of heater 2 or backplate 5 easily; fold-type steel panel 5 is too short then can not to keep off the slag that flies to survey; do not have the effect of protection furnace sealing port, thus the length of fold-type steel panel 5 should according between the size of body of heater and melting kettle 1 and the body of heater 2 apart from deciding.The upper end of fold-type steel panel 5 is mounted in the inboard of bell 4 in addition, and their connection can be welding, also can be the connection of adopting other method.
Fold-type steel protector is housed compared with prior art in vacuum melting furnace, significantly improve the service life of vacuum rubber sealing ring, and the ablated phenomenon of the sealed port of having avoided vacuum drying oven, guaranteed the vacuum-packed reliability of vacuum bell and body of heater port, it is simple in structure to adopt this protector also to have, install easily, and safety in utilization is reliable.
