Abstract
The utility model provides a continuous casting production device of thick large-section cast iron bars. The continuous casting production device comprises a crystallizer and a heat preserving furnace, wherein a hearth is installed in the heat preserving furnace, a graphite sleeve is installed in the crystallizer and is communicated with the hearth, an isolating ring is installed on the end portion, connected with the hearth, of the graphite sleeve, and the sectional area of the outlet of the hearth is smaller than that of the inner hole of the isolating ring and greater than or equal to one half of the sectional area of the inner hole of the isolating ring. By the adoption of the structure, the continuous casting production device has the advantages that as the isolating ring is installed on the end portion, connected with the hearth, of the graphite sleeve, the graphite sleeve is prevented from being directly contacted with the molten iron outlet of the hearth, and the problems that breaking-out occurs easily when the thick large-section cast iron bars are pulled rapidly, and scabbing, cracking and even furnace freezing when the thick large-section cast iron bars are pulled slowly are resolved; besides, as the area of the molten iron inlet is decreased, the flowing speed of supplemented molten iron is promoted, the upper sections and the lower sections of the thick large-section cast iron bars are uniform, the rate of finished products is promoted, and work efficiency is enhanced.
Description
Technical field
The utility model relates to a kind of continuous casting production device of thick and large section cast iron profile material.
Background technology
At present, hole dimension was the same in the size of the graphite arrival end in the production of cast iron profile material horizontal casting in the used crystallizer, the outlet of holding furnace molten iron was with graphite cannula, especially there is following shortcoming in such structure when producing large specification section bar: because the outlet of holding furnace molten iron directly communicates with graphite, molten iron temperature, flow affect very sensitive on metal freezing in the crystallizer, draw fast leakiness during drawing, easily scab when drawing is slow, crackle, even freeze stove; Need larger cooling water inflow; Because the molten iron inlet-duct area is larger, replenish the iron flow velocity slower, the aggravation section bar is the section inhomogeneities up and down, and yield rate reduces, and production efficiency is low.
The utility model content
The utility model proposes a kind of continuous casting production device of thick and large section cast iron profile material, it is kept apart the molten iron in graphite cannula and the holding furnace effectively, solve drawing and drawn leakiness when fast, draw scab when slow, crackle and freeze stove and the section bar problems such as section is inhomogeneous up and down, improve yield rate, enhance productivity.
The technical solution of the utility model is achieved in that a kind of continuous casting production device of thick and large section cast iron profile material, comprise crystallizer and holding furnace, be provided with burner hearth in the described holding furnace, be provided with graphite cannula in the described crystallizer, described graphite cannula is communicated with burner hearth, described graphite cannula is provided with shading ring in the end that is connected with burner hearth, and the area of section of described furnace outlet is less than shading ring inner hole section area and more than or equal to half of shading ring inner hole section area.
As preferably, the area of section of described furnace outlet is half of shading ring inner hole section area.
As preferably, described crystallizer comprises water inlet pipe, outlet pipe, inner sleeve, overcoat, and forward flange and rear flange form waterway between described inner sleeve and the overcoat.
As preferably, described overcoat, inner sleeve are welded to connect with forward flange, rear flange respectively.
As preferably, described crystallizer is connected with wedge by the quick change plate with holding furnace.
As preferably, described shading ring is identical with size with the shape of graphite cannula endoporus.
As preferably, described shading ring and holding furnace coupling part are fastening by refractory material.
The beneficial effects of the utility model are: after adopting said structure, owing to being provided with shading ring in the graphite cannula end that is connected with burner hearth, avoided graphite cannula directly to contact with the outlet of burner hearth molten iron, solved the drawing section bar and drawn easy bleedout when fast, draw easily scab when slow, crackle even the problem of freezing stove, and the molten iron inlet-duct area diminishes, replenishing the molten iron flow velocity accelerates, section is even up and down to make section bar, improves yield rate, enhances productivity.
