Description
Technical field
This utility model belongs to aluminum processing technology field, is specifically related to a kind of electrical heating inert gas shielding high temperature chute, for Aluminum sheets continuous casting and rolling.
Background technology
At present, when Aluminum sheets continuous casting and rolling, the aluminum liquid of 700 DEG C flows out from aluminium melting furnace, case before high temperature chute, filter, degasification tank entrance milling train；Aluminum liquid stream, when high temperature chute, conducts heat to chute and air, causes that temperature of aluminum liquid reduces, affect the rolling of Aluminum sheets；Due to the oxygen reaction in aluminum liquid and air, cause that aluminum liquefaction studies and point change, affect Aluminum sheets quality, and at aluminum liquid Surface Creation oxide-film, roll and can stick in chute interior walls after terminating, it is necessary to after cleaning, could again pass into aluminum liquid；Domestic existing high temperature chute adopts simple and easy upper cover, does not reach heat insulation and sealing effectiveness；Combustion gas is adopted to be passed directly in chute and carry out chute preheating, it is impossible to be precisely controlled chute and the temperature of aluminum liquid.
Utility model content
The purpose of this utility model is to propose a kind of electrical heating inert gas shielding high temperature chute so that it is can keep temperature of aluminum liquid, and protect aluminum liquid not by air impact.
This utility model adopts the following technical scheme that for completing above-mentioned purpose
A kind of electrical heating inert gas shielding high temperature chute, described high temperature chute includes box hat, composite refractory liner and upper cover；In described composite refractory, lining has the groove arranged along its length；The bottom of described groove is contained with aluminum liquid；The top of described groove is provided with precast beam；Described precast beam be along the length direction of groove arrange multiple, and the distance between adjacent two precast beams is 800 ~ 1600m；The described upper surface of composite refractory liner, the upper surface of precast beam are respectively provided with groove；The projection that the groove convex-concave that the lower surface of described upper cover has the upper surface with refractory lining, the upper surface of precast beam has fastens；Described upper cover fastens with refractory lining, precast beam convex-concave and is formed as one the high temperature chute that upper surface seals, and is provided with electrical heating elements in the lower surface of upper cover；Described high temperature chute also includes the inert gas tube being connected with groove, and described inert gas tube is arranged on the side of groove.
The bottom of each described precast beam is provided with precast beam baffle plate, and multiple described precast beam baffle plates are positioned at described aluminum liquid；The gas compartment on groove top is divided into several independent sealed subregions by multiple described precast beam baffle plates.
Described precast beam adopts laid dry mounting means, it is therefore an objective to when clearing up groove or after precast beam fracture, in that context it may be convenient to removed by precast beam, change.
A kind of electrical heating inert gas shielding high temperature chute that the utility model proposes, designs groove, at the upper design boss that covers on composite refractory liner and precast beam, and upper and lower convex-concave combines and forms labyrinth, effectively prevents the circulation of gas inside and outside groove；Have precast beam baffle plate in precast beam bottom design, precast beam baffle plate inserts in aluminum liquid, the gas compartment on groove top is separated into the subregion of 800 ~ 1600mm length, can effectively ensure that the sealing of each subregion, it is to avoid the impact on whole piece groove of the groove gas leakage point；Described precast beam adopts laid dry mounting means, is convenient for changing；Pass into noble gas by inert gas tube to groove cavity upper space, make noble gas aluminium coating liquid surface, effectively stop aluminum liquid and the oxygen reaction in air, it is ensured that the quality of aluminum liquid；Design has electrical heating elements, is connected with outside temperature control system, is precisely controlled temperature of aluminum liquid, completely eliminates temperature and reduces aluminum liquid quality and the adverse effect to rolling.
