Abstract
The present invention provides an explosion forming method for a continuous casting crystallizer which comprises the following steps: the inner surface of a straight copper pipe 1 is processed to a cylindrical surface, and the outer surface is processed to a conical surface; a processed core rod 2 in arranged in the straight copper pipe; three sections of explosive rings 3 with gaps are distributed outside the straight copper pipe, the angle between every two gaps is 90 to 150 DEG, and the angle between every adjacent two sections of gap centers is 180 DEG; explosive arranged in water is detonated; drug sticks 4 are distributed outside the pre-bent straight copper pipe in a curve mode, and a mold is pasted for explosion. The present invention has the advantages of simple technology and low cost, can be used for manufacturing a continuous casting crystallizer, can be also suitable for manufacturing a bent pipe with high precision and for repairing the existing continuous casting crystallizer.
Description
The present invention relates to a kind of manufacture method of continuous cast mold, especially a kind of explosive forming process.
Crystallizer is the heart of conticaster, all the continuous casting molten iron is all by just being solidified after the crystallization, because the shape of crystallizer is very special, it is an interior pore area tapering, arc pipe with the radius of curvature about 12500mm, the inner surface dimensional tolerance must not surpass 0.05mm, and the radius of curvature tolerance is no more than 30cm.All make with extrusion in the world, large-scale and accurate extruder be arranged, invest hugely, the cost costliness is for example wanted $10,000 yuan at the crystallizer (the outside water jacket that comprises crystallizer) that the U.S. buys a φ 450.
The purpose of this invention is to provide that a kind of manufacture craft is simple, cost is low, can explode into straight copper tube the explosive forming process of the continuous cast mold that accurate endoporus is arranged of an arcuate shape that the regulation radius of curvature arranged.
Technical solution of the present invention is: a kind of explosive forming process of continuous cast mold comprises the steps;
A, straight copper tube 1 is processed into inner surface is cylinder, and outer surface is the conical surface;
B, the plug 2 that processes is inserted in the straight copper tube;
C, three sections explosive rings 3 that have breach are distributed in outside the straight copper tube, the shared angle of circumference of each breach is 90～150 °, and adjacent two sections breach centers differ 180 °;
D, insert in the water explosive initiation;
E, again medicinal strip 4 is evenly distributed in outside the straight copper tube after the pre-bending with curve-like, pastes the mould blast.
Describedly again medicinal strip 4 be can be water barrier cloth medicine method with the curve cloth prescription method that curve-like is evenly distributed in the outer subsides mould blast of straight copper tube after the pre-bending.
Described curve cloth medicine can be spiral cloth medicine or serpentine cloth medicine.
The present invention compares with prior art, owing to use explosive method promptly to can be made into a continuous cast mold that accurate endoporus is arranged that the arcuate shape of regulation radius of curvature is arranged, technology is simple and cost is low, not only can be used for making continuous cast mold, also applicable to the bend pipe of making high precision and repair existing continuous cast mold.
Fig. 1 is an embodiment of the invention pre-bending process schematic diagram.
Fig. 2 has the schematic diagram of the explosive ring of breach for the embodiment of the invention.
Fig. 3 is that embodiment of the invention serpentine cloth medicine launches schematic diagram.
Fig. 4 is that embodiment of the invention helical cloth medicine launches schematic diagram.
Fig. 5 is an embodiment of the invention water barrier cloth medicine schematic diagram.
The present invention will be further described below in conjunction with drawings and Examples:
Embodiment 1: as shown in Figure 1, in being processed into the extruding straight copper tube 1 of deoxidation phosphor-copper for cylinder, be the conical surface outward, process a plug 2 on request with Digit Control Machine Tool, plug 2 hardness HRC 〉=50～52, plug 2 is placed straight copper tube 1, explosive is affixed on outside the straight copper tube with the form that has the explosive ring of breach shown in Figure 2, the shared angle of circumference of breach is 90 °, adjacent two sections explosive breach centers differ 180 °, be centered close to positive lower end as first section explosive breach, second section explosive breach then is positioned at positive upper end, and the 3rd section explosive breach then is positioned at positive lower end again.The straight copper tube of the good explosive of cloth is put into water with explosive initiation, then straight copper tube 1 reaches the pre-bending degree, straight copper tube after the pre-bending 1 is taken out, the S shape cloth medicine method that plasticity rubber water-proof explosive 4 usefulness are shown in Figure 3, be distributed on straight copper tube 1 outside, also place water to ignite and promptly paste the mould blast, straight copper tube 1 is promptly made standard compliant continuous cast mold.
Embodiment 2: as shown in Figure 1, extruding straight copper tube 1 with pure red copper is processed into the interior cylinder that is, outer is the conical surface, process a plug 2 on request with Digit Control Machine Tool, plug 2 hardness HRC 〉=50～52, plug 2 is placed in the straight copper tube 1, the form of the explosive ring that has breach that explosive bar 3 usefulness are shown in Figure 2 is affixed on outside the straight copper tube, the shared angle of circumference of breach is 150 °, adjacent two sections explosive breach centers differ 180 °, the straight copper tube of the good explosive of cloth is put into water with explosive initiation, then straight copper tube 1 reaches the pre-bending degree, the straight copper tube after the pre-bending 1 is taken out, with plasticity rubber water-proof explosive with helical cloth prescription formula shown in Figure 4, be distributed in outside the straight copper tube 1 with water barrier cloth medicine method, water barrier cloth medicine method is about to medicine and is pasted on the paper web 5 as shown in Figure 5, with paper tube sleeve outside straight copper tube 1.Put it in the water then and ignite, just make standard compliant continuous cast mold.
