Compared with common honeycomb duct, the tundish honeycomb duct has high dimensional precision, simple masonry and assembly; the inner surface of the tundish honeycomb duct is not provided with brick joints; the tundish honeycomb duct has the advantages of erosion resistance, long service life and no pollution for the steel liquid; the surface is not easy to have adhering dross; and the tundish honeycomb duct is easy to clean and can continuously pour liquid steel for more than 1000 tons.
Description
Technical field:
The utility model relates to the vacuum-casting technical field, particularly a kind of used for vacuum ingot casting tundish mozzle.Be specially and be placed on the vacuum chamber lid, a kind of device between tundish and ingot mould plays when vacuum pouring, and the molten steel that flows out middle water containing opening diffusion dress attitude is gathered into stream, guarantees that molten steel pours in the ingot mould of vacuum chamber.
Background technology:
The effect of tundish mozzle is to collect and introduce the steel stream that middle water containing opening under vacuum state is dispersed in the ingot mould, be the necessary equipment of vacuum-casting, the tradition mozzle is to be assembled by eight guide ring bricks and a graphite cannula, there is the slit between every ring brick, not anti-molten steel is washed away during cast, the pouring molten steel amount of average each mozzle does not reach 400 tons, and assembling is complicated, cleaning difficulty during logotype.
The tundish mozzle directly contacts with molten steel in casting process, and the floating foreign chance was very little after molten steel entered steel ingot through mozzle, and therefore, its abrasion resistance can directly have influence on the internal soundness of molten steel.Traditional mozzle by eight guide ring bricks and a graphite cannula combination, because there is brickwork joint in inwall, the erosion of anti-molten steel is not high, and its refractory material is easily washed away to be entered in the mould, whenever water a stove after inner surface leave a lot of residual steel, after burning the oxygen cleaning, the mozzle inner surface being caused certain damage, and the very bad cleaning of residue of inner surface adhesion, after using the 2-3 stove, just can not continue to use, graphite cannula, guide ring brick to be refilled iron-clad after installing from level to level, troublesome poeration during installation.
The utility model content:
The purpose of this utility model is to provide a kind of used for vacuum ingot casting tundish mozzle, and this mozzle is a monoblock type tundish mozzle technology, and being specially the mozzle brick is to fire with refractory material integral body to form, and its material is the Al-C refractory material.
Technology technical purpose of the present utility model is implemented in the following manner:
A kind of used for vacuum ingot casting tundish mozzle is made up of mozzle brick, metal shell and metal bottom bracket, and it is characterized in that: the mozzle brick is arranged on the metal bottom bracket, and at the sheathed metal shell of the periphery of mozzle brick, metal shell is fixedlyed connected with metal bottom bracket.
Be provided with the base plate and the cant board vertical with base plate of circular hole in the middle of described metal bottom bracket includes, the base of this cant board is positioned on this base plate neighboring; The outside, lower end of described mozzle brick is provided with boss, and this boss is arranged on the base plate of metal bottom bracket.
Described cant board is vertical pipe shape.
Described metal shell is arranged on the boss.
Between metal shell and mozzle brick, add and fill river sand.
This mozzle brick is to be fired by monolithic refractory to form.
Outer surface of upper at the mozzle brick is provided with the lifting groove that is used to lift and stays.
Be welded with the installation baffle plate (3) that is used on vacuum cover, installing with the location in the outer surface of upper of metal shell 5.
The bottom inner surface of described mozzle brick has the fillet of the dross of preventing.
Described metal shell is to be welded into iron sheet, and the outside is welded with and is used for installing on vacuum cover and the installation baffle plate of locating at an upper portion thereof.
The utility model is designed to the monoblock type mozzle, and dimensional accuracy height, assembling are simple, inner surface does not have anti-the washing away of brickwork joint to be difficult for the dross easy to clean, but the continuous pouring molten steel can reach the requirement of producing 600 tonnes of steel ingots more than 1000 tons.
Below in conjunction with Figure of description, the utility model is elaborated as follows by specific embodiment:
