Description
Technical field
The utility model relates to spheroidal graphite cast iron production unit technical field.
Background technology
Spheroidizing is important process procedure during spheroidal graphite cast iron is produced, and adopts which kind of nodulizing process to be directly connected to the quality of nodularization quality, the height of equipment input and the quality of operating environment.Present nodulizing process pours method, subcontracts method, covers the bag method, feeds a silk method, sprays magnesium method etc.Advantages such as wherein spraying the magnesium nodulizing process and be new technology in recent years, is that the optimised process spray magnesium desulfurization technology with hot metal pretreatment has been applied in the molten iron spheroidizing, and it is low to have a spheroidizing cost, and technical process is simple, and the nodularization molten steel quality is stable.
The spheroidizing of spray magnesium is to utilize the winding-up carrier gas that the magnesium grain is jetted in the nodularization bag, makes the magnesium of possessing certain content in the iron liquid, reaches the purpose that makes the molten iron nodularization.Spray magnesium spheroidizing equipment mainly is divided into: winding-up air-channel system, spray gun hydraulic efficiency system, feed and storage system, demonstration and supervisory system, nodularization bag system.The winding-up air-channel system pressurizes and provides in order to feed hopper by nitrogen pipeline and helps blowing carrier gas; The spray gun hydraulic efficiency system is mainly used in the lifting of spray gun, and the nodularization clad is fixedly arranged at the top of spray gun, and the nodularization clad can the lifting with the lifting of spray gun, and the nodularization clad covers in nodularization and wraps mouth when falling.Feed and storage system are in order to store magnesium grain and winding-up magnesium grain in spray magnesium pipeline; Show and supervisory system is used for showing the working order etc. of current air pressure, flow, feed bin residual content and hydraulic pressure and the air pressure flow is controlled default spray magnesium amount; The nodularization bag system makes molten iron reach the purpose of nodularization in order to carry out spheroidizing reacion.
Spray magnesium molten iron nodularization bag is one of production unit important in the spray magnesium spheriodization process thereof, the nodularization clad is fixedly arranged at the top that nodularization in the past wraps in spray gun, though designed the nodularization clad, but still there is following point in the nodularization bag in the nodularization process: if the nodularization amount runs out of the production of next procedure at least, iron phenomenons such as next procedure are arranged; If the nodularization molten iron spatters that iron is serious to the nodularization amount at most, contaminate environment, staff's workload strengthens, may cause staff's scald, and the specific absorption of magnesium is low, has increased the consumption of magnesium.
The utility model content
The technical problems to be solved in the utility model provides a kind of spray magnesium molten iron nodularization bag, have splashproof iron, improve Working environment, reduce the staff labour intensity, can improve magnesium specific absorption, advantage such as reduce cost.
Technical solution adopted in the utility model is: a kind of spray magnesium molten iron nodularization bag, comprise inclusion, and the inclusion fire-resistant lid of splashproof that is provided with suitable for reading, fire-resistant the covering of splashproof is provided with the hole.
The fire-resistant lid of splashproof is fixed on the inclusion, also can be movable, and namely the fire-resistant lid of splashproof can be opened.
The fire-resistant lid of splashproof can be spliced to form for two blocks of notched refractory brick.
Preferred structure, hole are long strip shape or bird-caging.
The beneficial effect that adopts technique scheme to produce is: spray magnesium molten iron nodularization bag has splashproof iron, improve Working environment, reduce the staff labour intensity, can improve magnesium specific absorption, advantage such as reduce cost.Be provided with the fire-resistant lid of splashproof because spray magnesium molten iron nodularization bag inclusion is suitable for reading, thereby increased the nodularization amount, improved the output of spheroidal graphite cast iron; Also effectively prevent splashing of molten iron, avoided spattering the scald that iron may cause; Also reduced the leakage of magnesium steam, reduced the consumption of magnesium, the winding-up magnesium grain time shortens; Also very easy in use.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Among the figure, the fire-resistant lid of 1 splashproof; 2 holes; 3 inclusions.
Embodiment
The utility model comprises inclusion 3, the inclusion 3 fire-resistant lids 1 of splashproof that are provided with suitable for reading, and the fire-resistant lid 1 of splashproof is provided with hole 2.The fire-resistant lid 1 of splashproof is fixed on the inclusion 3, also can be movable, and namely the fire-resistant lid 1 of splashproof can be opened.The fire-resistant lid 1 of splashproof is that two blocks of notched refractory brick are spliced to form, and hole 2 is long strip shape or bird-caging, and is simple in structure, practical.
Be provided with the fire-resistant lid 1 of splashproof because spray magnesium molten iron nodularization bag inclusion 3 is suitable for reading, thereby increased the nodularization amount, guaranteed to provide spheroidal graphite cast iron rapidly, continuously.The design of the fire-resistant lid 1 of splashproof has also effectively prevented splashing of molten iron, has reduced the consumption of molten iron, has saved production cost, has alleviated staff's labour intensity, has improved Working environment, has avoided spattering the scald that iron may cause.The design of the fire-resistant lid 1 of splashproof has also reduced the leakage of magnesium steam, thereby has improved the specific absorption of magnesium, and the consumption of magnesium grain reduces, and the winding-up magnesium grain time shortens.
The fire-resistant lid 1 of splashproof is that two blocks of notched refractory brick are spliced to form, and is fixed on the inclusion 3, and is easy to make, cost is lower.
The design of this nodularization bag is also very easy in use, and the hole 2 on the fire-resistant lid 1 of splashproof is long strip shape or bird-caging, is fit to stretching into of spray gun, the producing of the injection of molten iron and nodularization molten iron.
Molten iron injects nodularization bag inclusion 3 by the hole 2 on the fire-resistant lid 1 of splashproof during use, the spray gun hydraulic efficiency system stretches into nodularization bag inclusion 3 with spray gun by hole 2, spray gun winding-up magnesium grain, in nodularization bag inclusion 3, molten iron is carried out spheroidizing, after the spheroidizing nodularization molten iron is produced by hole 2, namely finish molten iron spheroidizing process, easy to use.
