Abstract
The utility model discloses an electroslag remelting crystallizer for producing high-speed steel, which comprises a copper inner sleeve, a steel housing, a water inlet pipe and a water outlet pipe, wherein the copper inner sleeve is arranged in the steel housing, and the upper ends and the lower ends of the copper inner sleeve and the steel housing are respectively welded with a flange; the copperinner sleeve, the steel housing and the flanges form an enclosed annular cold water room; the outer wall of the steel housing is provided with the water inlet pipe and the water outlet pipe; the water inlet pipe and the water outlet pipe are communicated with the annular cold water room; and the cross sections of the copper inner sleeve and the steel housing respectively are oval, so the flangesare also oval. When being used for the electroslag remelting production of high-speed steel ingots, the crystallizer can change the distribution of the carbides in electroslag ingots in the directionsof major and minor axes, and is favorable for forging. In the subsequent forging to form slabs, the oval electroslag ingots formed simultaneously can reduce the forging deformation in the minor axis,increase the production rate and reduce the tearing tendency of the high-speed steel in the forging process.
Description
Technical field
The utility model relates to a kind of rapid steel esr solidification and crystallization device.
Background technology
The remelting crystallizer is the essential support equipment of electroslag furnace device fabrication electroslag ingot, and it is a kind of device that molten steel crystallizes into electroslag ingot gradually in crystallizer in reflow process.The esr crystallizer is the large-scale copper-steel welding construction body of working under hot conditions; In reflow process, water coolant is flowed into by crystallizer bottom water inlet pipe, cooling layer in crystallizer is copper between cover and the outer cover of steel plate, by the molten steel in the designed processing condition cooling crystallizer, the crystallization velocity of control molten steel forms electroslag ingot, and water coolant flows out from the rising pipe on crystallizer top.
Chinese patent " novel esr crystallizer ", the patent No. 00233233.7 discloses a kind of such steel fusing of margin coagulation system, it is by circular copper inner sleeve, circular steel casing, water inlet pipe, rising pipe and circular compositions such as last lower flange, therefore it is circular producing its cross section of electroslag ingot that forms, the distribution of carbides of ESR ingot is along the cross section basically identical when being used for producing rapid steel, but when slab is forged in the electroslag shallow lake of this circle, because the unit elongation of slab cross-sectional length direction and width exists than big-difference, and it is long to be formed on the cross section, distribution of carbides on the broadside is inhomogeneous, directly influences the mechanical property of high speed steel blank; Simultaneously, circular ESR ingot owing to excessive along the deformation quantity of a direction (being thickness direction), reduced productivity and has caused rapid steel to be easy to cracking in forging process when follow-up forging is processed to form slab.
The utility model content
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model is, a kind of esr crystallizer that rapid steel is produced that is used for is provided, it not only helps the reasonable distribution of carbide in the flat parison material of rapid steel, and can effectively reduce the cracking of rapid steel in forging process.
In order to solve the problems of the technologies described above, the esr crystallizer that is used for rapid steel production of the present utility model, comprise copper inner sleeve, steel casing, water inlet pipe and rising pipe, described copper inner sleeve places in the steel casing, two ends up and down at copper inner sleeve and steel casing are welded with flange respectively, described copper inner sleeve, steel casing and flange form the annular cold water chamber of sealing, the outer wall of steel casing is provided with water inlet pipe and rising pipe, this water inlet pipe and rising pipe are connected with annular cold water chamber, the cross section ovalize of described copper inner sleeve and steel casing, described flange also are oval flange.
After adopting said structure, because the cross section oval in shape of crystallizer, water coolant in the annular cold water chamber between steel casing and the copper inner sleeve, different to the cooling of the molten steel in the crystallizer along oval-shaped all directions cooling power, the short-axis direction rate of cooling maximum of oval cross section and long axis direction minimum, therefore the ESR ingot that forms during solidification of molten steel organizes distribution of carbides and circular ESR ingot in the rapid steel especially to have tangible difference, thereby changed the distribution of carbides on the major and minor axis direction in the ESR ingot, the distribution of carbides that makes rapid steel forge in the flat parison material is more reasonable, both help improving the mechanical property of high speed steel blank, also helped forging processing; The oval ESR ingot of Xing Chenging when follow-up forging forms slab, can reduce the forging deformation quantity along short-axis direction simultaneously, boosts productivity, and has reduced the tearing tendency of rapid steel in forging process, has improved the yield rate of high speed steel blank greatly.
A kind of preferred implementation of the present utility model, the copper inner sleeve of described elliptical shape and steel casing are welded to each other fixing by weld seam and oval flange.Adopt welding fixing, not only help improving the firm performance of connection, and processing and fabricating is convenient.
A kind of preference embodiment of the present utility model, described water inlet pipe is positioned at the lower position of steel casing, and rising pipe then is positioned at the upper position of steel casing.Adopt thisly, and, help improving the cooling performance of rapid steel in the structure of top water outlet in the water inlet of annular cold water chamber bottom.
