Abstract
The present invention discloses a composite steel plate blank and a fabrication method thereof. The present invention has the advantages of low cost and easy realization. The density of the composite steel plate blank is larger than that of a steel blank which is obtained by using a traditional process and approaches to rolling density. The combination of two kinds of steel is compact without a loosening phenomenon. The interior of the composite steel plate blank has no air holes, texture is uniform and no slag inclusion phenomena exist. The composite steel plate blank which is produced by using the technology of the present invention has the advantages of less equipment investment, large output and easy operation, and cost is reduced compared with a traditional technology. The composite steel plate blank is formed by alternately and compactly superimposing and compounding at least one layer of basic steel and more than one layers of other kinds of steel, and is characterized in that before straight correction, the composite steel plate blank forms an annular shape namely that the basic steel and other kinds of steel are alternately and compactly superimposing into an annular composite steel plate blank.
Description
The invention belongs to metallurgical technology field, relate to a kind of composite steel sheet billet and manufacture method thereof specifically.
Composite steel sheet billet is meant that slab core simultaneously uses basic steel (as carbon steel), the another kind of steel (as stainless steel) of slab core another side outsourcing, and the conventional method of producing clad steel is to use technologies such as ingot casting, hot rolling, explosive welding (EW) and built-up welding.Since complex manufacturing, the cost height, thereby limited and used and development.
The objective of the invention is to disclose a kind of composite steel sheet billet, disclose its manufacture method simultaneously.Its advantage is low-cost, is easy to realize.Can criticize production, the composite steel sheet billet density of being produced is bigger than the steel billet that obtains with traditional handicraft, near rolling density, and the tight no loose phenomenon of combination between two kinds of steel, and inside does not have pore, quality is even, and no slag inclusion phenomenon adopts this explained hereafter composite steel sheet billet, equipment investment is few, output is big, easy operating, and cost is lower than traditional handicraft.
Composite steel sheet billet of the present invention is by the tight stack plate slab that is composited alternately of one deck basic steel and the other steel more than one deck at least, it is characterized in that alignment before composite steel sheet billet in the form of a ring, promptly basic steel and other steel alternately closely are superimposed as ring-like composite steel sheet billet.
Composite steel sheet billet of the present invention is characterized in that described basic steel is a carbon steel, and described other steel is a stainless steel, and ring-like composite steel sheet billet ectonexine is a stainless steel, and the intermediate layer is a carbon steel.
The capital equipment that constitutes this technology is by two electric furnaces and a centrifugal casting machine, produce the required molten steel of this technology respectively by two electric furnaces, inject in the centrifugal casting machine with ratio in certain sequence then, treat after the molten steel crystallization, it is taken out straightening, obtain composite steel sheet billet.
The manufacture method of composite steel sheet billet of the present invention, its processing step is:
A. produce required basic molten steel of this technology and other steel water respectively by at least two electric furnaces;
B. the temperature that heats centrifugal casting machine type tube rises to preheat value;
C. by one of electric furnace other steel water of in casting machine, casting;
D. treat the near initial stage of other steel coolant-temperature gage during crystallization temperature, by another electric furnace basic molten steel of in casting machine, casting;
E. when basic steel be water-cooled to the initial stage during crystallization temperature again by the electric furnace first other steel water of in casting machine, casting;
F. so circulation forms the ring-type composite steel sheet billet until each layer of casting composite steel sheet billet in centrifugal casting machine;
G. treat that the temperature of ring reduces to below the setting temperature, at first stop centrifugal casting machine, in centrifugal casting machine, take out the ring-type composite steel sheet billet;
H. reduce in temperature and cut off the ring-type composite steel sheet billet more than 900 ℃, enter straightener again, obtain the rectangle composite steel sheet billet at last its alignment.
This technology is owing to adopted the method for centrifugal casting, so the composite steel sheet billet density of producing is bigger than the steel billet that obtains with traditional handicraft, near rolling density, the tight no loose phenomenon of combination between two kinds of steel, and inside does not have pore, quality is even, and no slag inclusion phenomenon adopts this explained hereafter composite steel sheet billet, equipment investment is few, output is big, easy operating, and cost average specific traditional handicraft reduces about 40%.
Fig. 1 is a ring-type composite steel sheet billet profile of the present invention
Embodiment:
By the required stainless steel water of electric furnace smelting; temperature rises to cast temperature (about 1600 ℃); by the required carbon element molten steel of electric furnace second smelting; temperature rises to cast temperature (about 1550 ℃); the temperature of centrifugal casting machine type tube is risen to about 200 ℃; then by the electric furnace first stainless steel water of in casting machine, casting; apply protection gas---argon gas simultaneously; treat that the near initial stage of stainless steel water temperature is during crystallization temperature; by the electric furnace second carbon element molten steel of in casting machine, casting; when carbon steel be water-cooled to the initial stage during crystallization temperature again by the electric furnace first stainless steel water of in casting machine, casting; the amount of required two kinds of molten steel is determined by the specification of composite steel sheet billet, casts in by three times and forms the ring-type composite steel sheet billet in the centrifugal casting machine, treats that the temperature of ring is reduced to about 1000 ℃; at first stop centrifugal casting machine; stop to apply protection gas then, in centrifugal casting machine, take out the ring-type composite steel sheet billet, reduce to 800 ℃ of disconnections in temperature; enter straightener again with its alignment, obtain the rectangle composite steel sheet billet at last.
