Detachable tungsten-molybdenum cylinder

Abstract

The invention discloses a detachable tungsten-molybdenum cylinder, which belongs to the technical field of metal materials and comprises a plurality of assembly units and a fixing device. The assembling units are mutually assembled and enclosed to form a cylinder wall; each assembling unit comprises at least three tungsten-molybdenum layers, the tungsten-molybdenum layers comprise the first tungsten-molybdenum layer, the second tungsten-molybdenum layer and the third tungsten-molybdenum layer which are sequentially arranged in an overlapped mode from outside to inside, reinforcing ribs are arranged on the first tungsten-molybdenum layer, the second tungsten-molybdenum layer and the third tungsten-molybdenum layer, and the reinforcing ribs enable the first tungsten-molybdenum layer and the second tungsten-molybdenum layer to be arranged in a staggered mode. A gap is reserved between the second tungsten-molybdenum layer and the third tungsten-molybdenum layer; the fixing device sequentially penetrates through the first tungsten-molybdenum layer, the second tungsten-molybdenum layer and the third tungsten-molybdenum layer to realize fixed connection of the three tungsten-molybdenum layers; the assembling units are fixedly connected with the interior of the hearth. The reinforcing ribs in different directions are arranged inside and outside the tungsten-molybdenum layer, so that the overall strength of the whole tungsten-molybdenum layer can be enhanced, the tungsten-molybdenum layer basically does not deform at high temperature, the temperature of a thermal field is kept stable, and the service life of the thermal field is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to a detachable tungsten-molybdenum cylinder. Background technique [0002] Materials are one of the four major industries in China, including organic polymer materials, composite materials, metal materials and inorganic non-metal materials. As a kind of metal material manufacturing, powder metallurgy technology develops together with other manufacturing methods with its irreplaceable unique advantages. Porous materials and other methods cannot produce or have advantages such as materials that are difficult to produce. Powder metallurgy is the technology of producing metal powder and forming and sintering metal powder or metal powder and non-metal powder mixture to produce powder metallurgy materials or powder metallurgy products. Powder forming is the basic process of powder material preparation process, and mold is the key process equipment to realize powder material for...

However, the temperature in the single crystal furnace is 2100°C, such a high temperature makes the life of the heat shield in the furnace not long

[0005] The main reason for the scrapping of the insulation layer is the continuous heating and cooling, so that the tungsten and molybdenum materials cannot expand or shrink completely synchronously, resulting in serious deformation. The deformation of the insulation layer directly leads to uneven temperature in the thermal field, so it must be scrapped
