Abstract
The utility model belongs to the technical field of the titanium alloy production, concretely relates to titanium alloy TC4 medium plate annealing flattening device comprises cast steel pressure flat board and thru hole, and open the cast steel pressure flat board surface has rice font slot, and the thru hole of diameter 30mm is cast out at rice font center, warp for a short time, and the roughness is high.
Description
Technical Field
The utility model belongs to the technical field of titanium alloy production, concretely relates to titanium alloy TC4 medium plate annealing flattening device.
Background
The rolling of the titanium alloy TC4 medium plate is generally formed by rolling with a plate hot rolling mill, the length is generally 5000-plus-2000 mm, the width is 1000-plus-1500 mm, the flatness of the hot rolled finished plate is low, because the titanium alloy TC4 has high strength and good rebound resilience, the traditional leveling equipment for the common steel plate cannot level the TC4 finished medium plate, the hot leveling difficulty is very high, and the cold leveling is completely impossible, the leveling of the TC4 medium plate by domestic and foreign production enterprises is difficult, generally, the annealing and leveling of the finished TC4 medium plate are synchronously carried out, in the annealing and cooling process, the cooling speed of the peripheries of the titanium alloy plate and the planished cast steel plate is high, the cooling speed of the middle position is low, so that the tensile stress near the middle position of the finished TC4 plate is caused, the warping phenomenon around the plate is caused, and the flatness is poor.
Disclosure of Invention
To the problem that above-mentioned exists, the utility model provides a titanium alloy TC4 medium plate annealing flattening device.
The utility model discloses a titanium alloy TC4 medium plate annealing flattening device comprises cast steel pressure plate and thru hole, and the main point lies in that cast steel pressure plate surface is opened there is rice font slot, and the thru hole of diameter 30mm is cast out at rice font center.
The specification of the groove shaped like a Chinese character 'mi' is as follows: the width is 30mm, the depth is 20mm, and the length is 150mm from the periphery.
The cast steel pressing plate is heat-resistant steel and contains heat-resistant steel which is heat-resistant above 950 ℃ and contains chromium, molybdenum and niobium.
The utility model has the advantages that: the steel casting of the pressing plate is innovative in structure, the central area of the titanium alloy plate can be cooled, the cooling speed of the whole titanium alloy plate is close, the deformation is small, and the flatness is high.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1 cast steel pressing plate and 2 through holes.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The utility model discloses a titanium alloy TC4 medium plate annealing flattening device, which comprises a cast steel flattening plate and through holes, and is characterized in that the surface of the cast steel flattening plate is provided with a groove shaped like a Chinese character 'mi', and the through holes with the diameter of 30mm are cast at the center shaped like the Chinese character 'mi'; the specification of the groove shaped like a Chinese character 'mi' is as follows: the width is 30mm, the depth is 20mm, and the length is 150mm from the periphery.
When the device is used, a titanium alloy plate is placed on a leveling furnace bottom plate of an annealing furnace, the cast steel pressing plate 1 is pressurized, the annealing furnace is heated and insulated, furnace cooling is started, a stainless steel pipe is inserted into a reserved annealing furnace fabrication hole and enters the through hole 2 of the cast steel pressing plate 1 to the surface of a titanium alloy plate, a thermocouple measures the temperature and the cooling speed of the periphery of the titanium alloy plate, the temperature and the cooling speed of the titanium plate in a central hole area are measured simultaneously, argon is introduced into a stainless steel pipe, the flow of the argon is adjusted, the peripheral temperature of the titanium alloy plate is monitored to be basically consistent with the temperature of the central area of the plate, the argon is closed, the titanium alloy plate is taken out of the furnace, the cast steel.
