Description
The instantaneous dense flow processing vessel that molten iron is carried out nodularization (wriggling, breed) continuously that the utility model relates to that a kind of magnesia carbon brick makes belongs to casting technology field.
CN1023573C (ZL91106380.3) patent disclosure of on January 19th, 1994 bulletin the nodularization of a kind of spheroidal graphite cast iron instantaneous dense flow, wriggling or inoculation container.Implementation process has in recent years proved its principle of design and the technologic reasonableness of frock.But find that also there are some defectives in it, as aspect nodulizing agent and the refractory materials, geometrical shape, molten iron flow velocity and the amount of sprue cup structure and relevant several parts and nodulizing agent add that factors such as speed and amount are used the continuous several times of treater and effect all has tangible influence.For example, nodulizing agent enters the burning of container chance molten iron immediate response from centre hole and results in blockage, thereby has influenced its continuous use.
The purpose of this utility model is, remedies the deficiency of prior art, but the nodularization of spheroidal graphite cast iron instantaneous dense flow, wriggling or the inoculation container of a kind of continuous several times use, rare earth and magnesium utilization coefficient height, non-environmental-pollution are provided.
The purpose of this utility model is achieved by the following technical solution.
The utility model is mainly communicated successively by powder delivering device, sub-material cup, sprue cup, thrust-augmenting nozzle, S shape passage, water seal top, discharge orifice and the hole of tapping a blast furnace, close stream chamber is formed in sprue cup, thrust-augmenting nozzle, S shape passage, water seal top, discharge orifice and the hole of tapping a blast furnace, it is outer to be the sandbox of filling high temperature material, above-mentioned sub-material cup center is the sub-material pipe, it is outer to be that fan-shaped feed port is encircled in the garden, and the molten iron inlet is arranged on the sub-material cup sidewall, along molten iron stream tangential direction flow deflector is arranged, the bottom is the cup end, and the inner ring sleeve brick is arranged in the sub-material cup.
Thrust-augmenting nozzle is communicated with sprue cup and S shape passage, and water seal withstands on S shape passage top and communicates with S shape passage, and bottom, water seal top is that discharge orifice is communicated with the hole of tapping a blast furnace, on discharge orifice, S shape passage and Kong Zaiyi the inclined-plane that tap a blast furnace.
Above-mentioned thrust-augmenting nozzle is to become diameter tube, and from top to bottom diameter is 80-120mm to 50-70mm.
It is that three or four arc angles are 70 ± 10 ° scallop hole uniform distribution that fan-shaped feed port is encircled in above-mentioned garden.
The height on water seal top is relevant in the indoor residence time of close stream with molten iron, molten iron residence time 10-15 second, water seal heights of roofs 250-350mm.
The discharge orifice diameter is 13-23mm.
Above-mentioned sub-material cup and close stream chamber are to be made of magnesium carbon shaped brick.
During the utility model work, nodulizing agent is quantitatively imported by powder delivering device, along the sub-feed tube vertical drop at sub-material cup center to the sprue cup centre, molten iron is done tangent line through flow deflector along sub-feed tube and is flowed, the chance scallop hole falls to entering the sprue cup rotation and descends, form conical negative pressure angle, nodulizing agent falls into natural being wrapped in by molten iron in this position and brings close stream chamber thrust-augmenting nozzle into.Nodulizing agent is melted at S shape passage, has prevented the generation of magnesium light and white cigarette, reduces environmental pollution.Because nodulizing agent is with the instantaneous adding of molten iron, solved nodulizing agent and concentrated the magnesium that adds spheroidizing, the unsafe factor of rare earth vapour pressure, thereby solved the environmental pollution of magnesium iron spheroidizing over 40 years, the disadvantage of high-risk, high-temperature operation.The utility model employing magnesium carbon shaped brick is changed close stream chamber and the sub-material cup is very convenient, has also improved the utilization coefficient of rare earth and magnesium simultaneously, has reduced production cost, has remarkable energy saving effect.But the utility model continuous several times is used.
The utility model is described in further detail below in conjunction with drawings and Examples.
