Embodiment Construction

[0031] specific implementation plan

[0032] A steel company implements the patent of this invention to manufacture thermal insulation materials that can be pasted with thermal insulation cotton to replace the inner thermal insulation cotton and the outer stainless steel plate composite sheathing technology, which is used for effective forging of metal materials such as difficult-to-deform high-temperature alloys (one-fire forging or multi-fire forging) Fire forging) insulation measures.

[0033] The stickable heat-insulating cotton provided by the invention is characterized in that: the stickable heat-insulating cotton is made of heat-insulating cotton (the heat-insulating and refractory "ceramic fiber blanket" widely supplied in the market is selected, and the main component is Al 2 o 3 +SiO2 2 , which is characterized by low thermal conductivity, low heat capacity, not easy to pulverize at 1200-1300 ℃ high temperature, still maintains good elasticity), double binder compo...

Abstract

This invention relates to adhesive heat isolation cotton and its process method, which is applied in forging with constant temperature of alloy with firm shape. The invention is characterized by the following: it comprises the isolation cotton, double adhesive agent, wherein, the isolation cotton is of ceramics fire wearing fiber in sale and its rectangle plate is distributed with parallel and crossed holes with distance between as 50mm and with depth less than the cotton thickness; the double adhesive agent is made by mixture of adhesive agent with room temperature and one with high temperature with their proportion as three to seven. The double adhesive agent in the cotton holes is above the surface of the cotton distributed discontinuously and finally for drying.

Description

technical field [0001] The invention relates to an insulating material for hot-working forging alloys in the metallurgical industry, in particular to an insulating material for hot-working forging of difficult-to-deform high-temperature alloys. Background technique [0002] Superalloys are important metal materials necessary for high-tech power devices such as modern aero-engines and rocket engines. It can withstand greater stress and be used for a long time under high temperature (generally 600-900°C), oxidizing atmosphere and gas corrosion conditions. Due to the high degree of alloying of superalloys, it is difficult to deform by hot working. Generally speaking, superalloys that are difficult to hot-forge and deform (blank, form) are called difficult-to-deform superalloys. At present, at home and abroad, there are three hot-working deformation methods for hard-to-deform superalloys: extrusion machine blanking, forging press forging, and hot-rolling mill wrapping rolling;...
