Technical field
The invention belongs to the continuous casting process units technical field of hollow cast iron profile material, be specifically related to a kind of continuous casting process units of hollow cast iron profile material.
Background technology
The hollow cast iron profile material of continuous casting; Have that dense structure, intensity are high, oil resistant is pressed, the characteristics of good toughness, make high-performance mechanical parts such as ring, cover, tube and so on and macropore ADI gear with its, be equal to or be superior under the prerequisite of solid cast section bar in mechanical property; But about economical with materials 50%; And its excellent processing characteristics reduction machine significantly adds cost, and is energy-efficient, is high densification, zero-fault, near-net-shape, the tough product that has both that the Department of Science and Technology is recommended.
Existing hollow cast iron profile material production has three kinds of modes basically, and first kind is adopted vertical drop-down batch (-type) continuous casting cast iron pipe process units, and this device is eliminated because of the section bar compactness difference of producing; Second kind of process units that adopts horizontal casting to add interior crystallizer produced hollow cast iron profile material; Because there is the big temperature difference in this device crystallizer top and bottom; For preventing that top leakage iron from slowing down pulling rate, cause the section bar bottom cold excessively, excessive with graphite cannula inwall frictional force; The tensile strength that surpasses graphite causes the graphite cannula bottom usually to be broken, and is difficult to realize producing continuously; The third adopts on centreless vertical and draws hollow cast iron profile material continuous casting process units; This device adopts " compound physical field " restriction moldings that synergy produced such as gravitational field, temperature field, electromagnetic field; Because it is comparatively strict to be somebody's turn to do the conditional request of " compound physical field " restriction molding; Production cost is high, has restricted the kind of section bar, has therefore limited its application.
Summary of the invention
The present invention is directed to the deficiency of prior art, the continuous casting process units of the hollow cast iron profile material that a kind of safety coefficient is high, product is stable, cost is low, production is stable is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
A kind of continuous casting process units of hollow cast iron profile material; Comprise inwall have the holding furnace of flame retardant coating, be positioned at holding furnace one side middle and lower part the side interface arrangement, be installed in the outer crystallizer on the crystallizer interface outside the side interface arrangement top; Outer crystallizer is made up of cooling jacket and outer graphite cannula; The inwall of outer graphite cannula and foundry goods profile match, and outer crystallizer carries out the crystallization cooling through its cooling jacket and outer graphite cannula to the section bar appearance, forms the section bar shell; Wherein: also comprise the interior crystallizer that is installed on the interior crystallizer interface of side interface arrangement bottom, be attached to heat-insulation layer, tapping hole, plug, cleaning door, stopper, the dowel hole between holding furnace inwall and the flame retardant coating and hang shackle; Said interior crystallizer is made up of cooling core and interior graphite cannula; The profile of interior graphite cannula and foundry goods inner wall shape match; Interior crystallizer carries out the crystallization cooling through cooling core and interior graphite cannula to the section bar inner surface, forms the section bar inner casing; Said tapping hole is located at the opposite side of holding furnace, and plug is installed on the tapping hole; Cleaning door is located at the opposite side of holding furnace and over against the side interface arrangement, stopper is installed on the cleaning door, and dowel hole is located on the base of holding furnace, hangs the both sides that shackle is located at holding furnace.
Tapping hole wherein according to the invention is downward-sloping shape; Said holding furnace shape of cross section is 2/3rds circular segments or rectangle.
The present invention is according to material different, and the cast iron hollow profile of different cross section shape and size size is chosen different upwards drawing process parameters, thereby realizes the continuous casting production of cast iron hollow profile.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention has increased heat-insulation layer outside flame retardant coating, makes holding furnace have double-layer heat insulation, has improved the heat insulation effect of holding furnace, has reduced the temperature difference of holding furnace, has improved the stability of product, has reduced because energy resource consumption and the environmental pollution that heating need cause;
2, the present invention uses outer crystallizer to form the section bar shell when drawing vertically upward forms foundry goods, and use interior crystallizer formation section bar cavity can conveniently be controlled the even moulding of section bar inside and outside wall and reduces production costs, and helps steady production;
3, the present invention is provided with cleaning door on holding furnace, has accelerated interface and has repaired speed, and cleaning door is opened when repairing stove, repaiies stove and finishes and promptly give shutoff;
4, the present invention is provided with quick location and fixture on holding furnace, and the shackle of hanging on the furnace wall uses, and makes to launch subsequent use holding furnace and become possibility, and this will effectively shorten changes the idle cost that crystallizer causes, and improves the service efficiency of continuous casting line.
