Embodiment Construction

[0021] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0022] The pure tungsten sheet rolling process of the present invention comprises the following steps:

[0023] Step 1: Heat and keep the pure tungsten sheet to be rolled to ensure its temperature is 150-250°C;

[0024] Step 2: Feed the heated pure tungsten sheet into the roll, at this time ensure that the surface temperature of the roll is 150-250°C, and the rolling speed is 4-7 m / min;

[0025] The third step: use the roller wiper to clean the surface of the roller in time;

[0026] Step 4: Reduce the gap value between the rolls, and repeat the above three steps until the tungsten sheet with the required thickness is obtained.

[0027] like figure 1 As shown, the present invention is provided with an electric heating tube 7 inside the roll 4, and an electric heating platform 5 is provided at the front part of the roll-in side of the ro...

Abstract

The invention relates to a rolling technology for a pure tungsten sheet and a device thereof. An electric heating pipe is arranged in a roller; an electric heating platform is arranged at the front part on a rolling-in side of the roller; the top surface of the electric heating platform is located at a peak on the outer periphery of a lower roller; a roller wiper is arranged on a rolling-out side of the roller; and a temperature control device is used for controlling the temperatures of the electric heating pipe and the electric heating platform. According to the rolling technology, the rolling temperature of the tungsten sheet is strictly controlled, the electric heating platform is utilized to heat the to-be-rolled tungsten sheet, and meanwhile, the roller is heated and kept warm, thereby ensuring deformation of the tungsten sheet within a suitable plastic temperature range all the time during the whole rolling process, avoiding oxidization, greatly promoting the yield and realizing batch and low-cost production of ultrathin tungsten sheets.

Description

technical field [0001] The invention relates to the field of metal material processing and preparation, especially the pure tungsten sheet rolling process and its equipment. Background technique [0002] Tungsten is a VIB group element of the periodic table. Its surface has a silver-gray luster, and its powder is dark gray. It has a high melting point, high strength, and elastic modulus, a small expansion coefficient, low vapor pressure, good electrical and thermal conductivity, and excellent corrosion resistance. The disadvantage is low temperature. Embrittlement and high-temperature oxidation are serious, so it is widely used in electrical, metallurgy, aerospace, medical, atomic energy industries and other fields. [0003] Due to the serious low-temperature embrittlement and high-temperature oxidation of tungsten materials, it brings difficulties to the pressure processing of tungsten. At present, the conventional tungsten sheet is usually processed with a thickness of 0.2...
