Description
Technical field
The utility model belongs to counter-gravity casting equipment field, and in particular to a kind of antigravity casting ceramic lift tube
Seal fixed structure.
Background technology
In antigravity casting, either low pressure casting, counter-pressure casting, suction pouring, current major part are all applied relatively low
In the non-ferrous metals casting of fusing point, it is common to use T-shaped ceramic lift tube, i.e., the ceramic lift tube of flanged disk.It is producing in batches
In the process, ceramic lift tube is immersed in molten metal always, is needed to be fixed on middle partition board and bottom plate, be repeatedly used, because
This generally requires to come in more complicated structures such as the ring flange upper surface of ceramic lift tube installation gate core, bushing, cover boards close
Sealing is determined, and installs, to replace ceramic lift tube cumbersome, and operator's time that works at high temperature is long, and influences production efficiency.
Particularly in antigravity casting high-temperature alloy casting, during steel casting as heat-resisting such as suction pouring, low pressure casting, metal closes
Golden smelting and pouring temperature is high, and general molten steel cast control is at 1500 DEG C or more, this is just to the sealing fixed structure of ceramic lift tube
Propose very high requirement.It is required that simple in structure, sealed reliable, heat-resisting quantity is good, and is easily installed, replaces, and ensures cast matter
Amount improves the service life of ceramic lift tube.And at present in counter-gravity casting equipment ceramic lift tube sealing fixed structure skill
Art is difficult to meet or be not suitable with the antigravity casting production of high-temperature metal alloys, needs to change prior art processes structure
Into.
