The technical solution of the utility model is: continuous casting production car formula mouth of a river apparatus for baking, it comprises the circular baking barrel of back cover under upper shed, along additionally arranging refractory seals packing ring on it, the pipe mirror peep hole of inner chamber is stretched in the positive side-wall hole weldering one of baking barrel, stretch into the exhaust fitting of inner chamber in another STH weldering one, exhaust fitting be connected to jet flow negative pressure axle haustorium outward; The inner chamber of baking barrel adopts flame-proof thermal insulation material ramming to become pot bottom-shape liner; Baking barrel is sitting in chassis.Corner Strapped universal wheel under chassis.
Baking barrel just below be welded with pipe, at pipe overcoat one helical compression spring, spring is plugged in the fixing base matched, and base is welded on square chassis, and chassis is welded with handrail, and below chassis, Corner Strapped has universal wheel.
Described jet flow negative pressure axle haustorium comprises circular little bellows, is fixed with suction tube at the inner chamber of its inlet end, and its bore size is greater than mouth of a river aperture size, is outwards fixed with penetrates airduct at the inner chamber of the exhaust end of little bellows, and suction tube inserts and penetrates airduct; Penetrate airduct and the nestable gap of suction tube is 1.5 ~ 3 ㎜,
The lower wall of little bellows is fixed with ajutage joint.
Effect of the present utility model is: 1, toast 1.2 ~ 1.5 hours, mouth of a river temperature can reach 800 ~ 1000 DEG C.2, gas saving 17500Nm
3/ time.3, improve conticaster casting rate, reduce power consumption about 6000 degree/heat, reduce molten steel and lose 5 tons/time.4, stopped flame to the roasting metaboly of tundish bottom spray, extended tundish service life, calculate the loss that can reduce by 2 centre inclusions for a year.5, stopped Yin Wendu inequality and caused the accident of bursting, having reduced potential safety hazard, make production direct motion.6, improve the site environment at the baking mouth of a river, stop Fire Radiation and smoke contamination.7, the actual bodily harm of remaining coal gas to employee is particularly avoided.8, simple to operate, convenient and swift, energy-saving and cost-reducing, safe and reliable.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
