Titanium-alloy-plate tandem-rolling temperature controlling device and temperature controlling tandem-rolling method

Abstract

A titanium-alloy-plate tandem-rolling temperature controlling device comprises annular induction coils, supporting frames, stone boxes, trusses, supports and colorimetric pyrometers. The trusses are arranged in front of rolling rollers correspondingly, each two colorimetric pyrometers are arranged on a cross beam of the corresponding truss, each colorimetric pyrometer is arranged on a vertical beam of one side of the corresponding truss, and the included angle of each colorimetric pyrometer and the titanium-alloy-plate surface can be adjusted; the supporting frames are arranged on the positions which are away from the trusses for 2 meters correspondingly, the stone boxes are fixed on the supporting frames, a rolled titanium-alloy plate passes from the inner portions of the stone boxes, and annular induction coil sets are arranged on the upper surfaces, the lower surfaces and the side surfaces of the two sides of the inner portion of each stone box; and the annular induction coil sets are all away from the surface of the titanium-alloy plate for 2 centimeters, each set of the annular induction coil sets comprises 3 annular induction coils, and the annular induction coils can heat the plate edge of the titanium-alloy plate after being electrified. According to the titanium-alloy-plate tandem-rolling temperature controlling device, the temperature difference in the titanium-alloy plate in the whole tandem-rolling process can be eliminated, the temperature of the titanium-alloy plate in the rolling process can be accurately controlled, and warping of panels is avoided.

Description

technical field [0001] The invention relates to the field of continuous rolling of plates, in particular to a temperature control device for continuous rolling of titanium alloy plates. Background technique [0002] Titanium alloy has low density and high tensile strength. In the range of -253-600 degrees Celsius, its strength is almost the highest among metal materials. It can form a thin and hard oxide film in a suitable oxidizing environment. Has excellent corrosion resistance. As people's demand for material consumption continues to develop to high-end, titanium alloys have gradually entered the wider heavy industry production fields such as chemical machinery, shipbuilding industry, automobile industry, oil and gas industry, food, medical treatment, etc. Civil consumption fields such as equipment and sports and leisure industries. At present, in the production process of titanium alloy slabs, the distance from the formation of titanium alloy slabs to the first rolling...

AI Technical Summary

Problems solved by technology

At present, in the production process of titanium alloy slabs, the distance from the formation of titanium alloy slabs to the first rolling pass is long. Due to the difference in heat dissipation conditions between the middle and edge of the slab surface, there is a temperature difference on the slab surface.
