Abstract
The invention relates to a laying method of a casting system in the technical field of casting. The laying method comprises the following steps: firstly, a plurality of gate positioning tables are fixed on a working table; then, a lifting bracket is arranged above the working table; cross gates are mounted at the lower side of the lifting bracket; ports of ceramic pipes in outlets of the cross gates are coated at the outer sides of the gate positioning tables; a mold is overturned to enable ingates to be upwards; ingate ceramic pipes are inserted in all the ingates, so that the upper end surfaces of the ceramic pipes in the ingates are positioned on the same horizontal plane; when sand flows to the upper port positions of the ceramic pipes in the ingates, the sand is scraped flatly; the lifting bracket is lifted to place at the upper side of the mold, so that the ceramic pipes in the ingates are in inserted connection with the ceramic pipes in the outlets of the cross gates one by one; inlets of the cross gates are connected with straight gates arranged outside; the sand flows again; when the sand is flatten to the positions of the cross gates, the lifting bracket is disassembled; the shaping of flowing sand is continued; and finally, the sand mold is overturned to finish the laying. The laying method can quickly build the casting system; the sealing among the ceramic pipes is excellent; and the quality of castings is better. The laying method is suitable for the production of bottom pouring type castings.
Description
Technical field
The present invention relates to a kind of laying method of running gate system, particularly a kind of laying method of running gate system of large-scale steel-casting.
Background technology
Large-scale steel-casting is in the time of casting Technology Design, consider the impact to fuse, die cavity and reduce molten steel oxidation, generally all adopt bottom gating, allow molten steel flow into casting mold die cavity from foundry goods bottommost, and by the size and number of technology Calculation and analog selection cast gate and sprue, steady in cavity filling process in order to ensure molten steel, reduce the turbulent volume gas bringing and splash, require the laying of cross gate necessary smooth; Because size and the tonnage of heavy castings are all very large, in casting process, the hydrostatic head of molten steel is very large, if running gate system intensity is low, easily causes sand washing or runout.
In actual modeling process, the laying of running gate system is all to lay in moulding quicksand process, after molding sand flows to a certain degree, stops quicksand, then lays running gate system.Because large-scale steel-casting ingate quantity is many, running gate system complexity, and the pot life of resin sand only has 40 minutes, and this will cause running gate system lay-up operation not meticulous to a great extent.Directly cause running gate system in process of deployment, to exist cross gate the problem such as not flow in running channel at same plane, loose sand, affect the mobility of molten steel in surface quality of continuous castings and casting process.
Summary of the invention
The object of this invention is to provide a kind of laying method of running gate system, can make cross gate lay smooth, running gate system builds more convenient, when cast, flows to running gate system without loose sand.
The object of the present invention is achieved like this: a kind of laying method of running gate system, comprises the steps:
1) on the work top of horizontal positioned, fix some cast gate positioning tables, the riding position of cast gate positioning table is corresponding one by one with the ingate position of mould; The external diameter of cast gate positioning table and cross gate outlet porcelain tube bore match;
2) hoisting bracket is set above work top, at hoisting bracket downside, cross gate is installed, cross gate is pegged graft and is formed successively by some porcelain tubes, cross gate be horizontally disposed with and and hoisting bracket between colligation fix, cross gate outlet porcelain tube mouth engage sleeves is contained in cast gate positioning table outside;
3) turnover mould makes ingate upwards, and on each ingate, the suitably ingate porcelain tube of height of plug-in mounting, is positioned in same level the upper surface of ingate porcelain tube, sprue is fixed on to mould side simultaneously; Then quicksand, when molding sand flows to ingate porcelain tube position of upper, strikes off;
4) lifting hoisting bracket, makes cross gate entirety depart from cast gate positioning table, after cross gate is lifted, then is placed in mould upside, makes ingate porcelain tube and the corresponding socket connection one by one of cross gate outlet porcelain tube, the import of cross gate is connected with the outlet of sprue simultaneously;
5) quicksand is again dismantled hoisting bracket in the time sanding flat cross gate position, continues quicksand moulding;
6) after moulding, sand mold is overturn, make cross gate be positioned at mould below, complete the laying of running gate system, can carry out subsequently casting operation.
By technical scheme of the present invention, running gate system that can rapid build foundry goods, has reduced quicksand on one side and has laid time of running gate system in a large number on one side; Concentrated labour intensity and the working environment that has improved moulding are reduced; It is fast that running gate system is laid speed, changed order of the prior art and laid one by one pattern, adopts modular mode to lay, and greatly improved the production efficiency of moulding quicksand; Whole cross gate is installed location on work top, and good seal between porcelain tube, flows to running gate system without loose sand, does not have burning into sand problem when cast, has ensured surface quality of continuous castings; Whole cross gate keeps level, has ensured the steady and good mobility of molten steel in casting process, makes casting quality better.The method is applicable to, in the production of various bottom pour mold formula foundry goods, be particularly suitable for the production of heavy castings.
During for ease of laying, cast gate positioning table is located fast, be provided with in length and breadth network for location ruling on described work top, cast gate positioning table is located by network for location ruling.
Be as a further improvement on the present invention, described work top is made up of ferrimagnet, and cast gate positioning table is made up of magnetic material, and cast gate positioning table is directly fixed on work top.The replacement scheme of the technical program is, work top is made up of ferrimagnet, and cast gate positioning table is made up of wood materials, on cast gate positioning table, lays magnet base, produces the suction-combining force cast gate positioning table is fixed between magnet base and work top.Above-mentioned two kinds of technical schemes all can make cast gate positioning table locate fast, and its dismounting speed is with fast, easy to operate.
For ease of lifting and fixing cross gate, described hoisting bracket comprises two crossbeams that parallel setting, is provided with hanger on crossbeam, between the two ends of crossbeam, is connected through longeron, is provided with connecting framework between longitudinal and cross beam.Connecting framework can crisscrossly arrange, and is convenient to the fixing cross gate of multiple spot.
