Abstract
The glass lubricant specially for hot extrusion of high temperature alloy pipe consists of Cr2O3 2-3 wt%, refractory cellulose 10-20 wt% and H glass 32-40 wt% except H2O, where H glass consists of Al2O3 10-18 wt%, CaO 12-18 wt%, Na2O 3-5 and B2O3 10-18 wt% except SiO2. The glass lubricant of the present invention has high temperature lubricating effect and heat isolating effect to reduce the decrease of blank temperature, and is chemically stable to produce no chemical reaction with blank metal, ropy and high in lubricating effect. Compared with available lubricant, the glass lubricant has raised product quality, lowered production cost, prolonged extruding mold life, lowered power consumption.
Description
Technical field:
The present invention relates to the processing technology of metal pipe material, a kind of glass lubricant specially for hot extrusion of high temperature alloy pipe and using method thereof are provided especially.
Background technology:
High temperature alloy pipe is the material that is widely used in energy conversion system key part in the industry such as Aeronautics and Astronautics aircraft, naval vessel, generating, rocket engine, nuclear reactor, locomotive and petrochemical complex.The effective means of high temperature alloy pipe base is hot extrusion processing, and the technology of extrusion processing most critical is exactly the lubricant technology.For nickel-base high-temperature alloy material, because intensity is very high, in extrusion process, the lubricant of employing must have the high temperature lubricating effect.
For stainless material or the lower superalloy of intensity, common lubricating method is that glass powder is spread upon on the blank and mould after the preheating, then with blank heating to extrusion temperature.Another kind method is that lubricant is heated to melting state, blank is placed in the lubricant dips, and pushes then.When above lubricating method was applied to the high temperature alloy pipe extruding, the problem of existence was that the extruded tube surface tear is serious, and squeeze is bigger, and the less extrusion machine of extruding tonnage can't be processed.
Summary of the invention:
Of the present inventionly provide a kind of glass lubricant specially that is suitable for the superalloy hot extrusion, realize the hot-pressed of high temperature alloy pipe, improve the quality of products and productivity, reduce cost by changing lubricant composition and lubricating system.
The invention provides a kind of glass lubricant specially for hot extrusion of high temperature alloy pipe, it is characterized in that lubricant is made up of following compositions, percentage by weight: Cr
2O
32～3 heat resistant type celluloses, 10～20H glass, 32～50H
2The O surplus.
In the glass lubricant specially for hot extrusion of high temperature alloy pipe of the present invention, used H glass better adopts following compositions, weight percentage: Al
2O
310～18CaO, 12～18Na
2O 3～5B

310～18SiO
2Surplus.
Wherein, SiO
2Weight percentage be preferably in 50～60.
The present invention also provides the preparation method of above-mentioned glass lubricant specially for hot extrusion of high temperature alloy pipe, it is characterized in that founding by described proportional arrangement H glass that shrend grinds into granularity less than the H glass micro mist of 0.07mm; With above-mentioned H glass micro mist, heat resistant type cellulose, the granularity Cr less than 0.1mm
2O
3Be mixed the ball milling homogenizing.
Glass lubricant specially for hot extrusion of high temperature alloy pipe of the present invention need successively be wrapped in woven fiber glass on the blank after the preheating in use, and every layer is coated with glass lubricant, oven dry; Blank heating is pushed behind extrusion temperature.
Glass lubricant specially for hot extrusion of high temperature alloy pipe of the present invention not only has the high temperature lubricating effect, also has heat-blocking action, has alleviated the reduction of blank temperature; And chemical property is stable, not with blank metal generation chemical reaction; Glass lubricant specially of the present invention becomes thick under use temperature, and lubricant effect is good.Thereby improved product quality, improved production efficiency, reduced production cost.Through examination, the life-span of Extruding die was enhanced about more than once when the life-span of Extruding die was than other lubricant of employing when adopting high temperature alloy pipe special lubricant for squeezing of the present invention; Extrusion tube blank shows that quality reaches requirement; Compare squeeze with other lubricant and reduce by 18%, reduced energy consumption; Slow down the reduction of blank surface temperature, improved the plasticity of material.Compare with the existing boring cold rolling process that adopts, material can be saved more than 10%, and efficient can improve more than 100%, and cost reduces more than 40%.
Embodiment:
Among the present invention, be that 19mm, external diameter are that the superalloy In718 of 60mm and the pipe of GH1140 have carried out the hot extrusion test to internal diameter respectively.Process is: woven fiber glass successively is wrapped on the blank after the preheating, and every layer is coated with the glass lubricant among the embodiment, wraps up three layers altogether, and oven dry forms the lubricated jointly combined lubrication mode of woven fiber glass and glass powder; Blank heating is pushed behind extrusion temperature.The test conditions of In718 is: 400 ℃ of mold preheating temperatures, 1120 ℃ of extrusion temperatures, extrusion ratio 4.The test conditions of GH1140 is: 400 ℃ of mold preheating temperatures, 1100 ℃ of extrusion temperatures, extrusion ratio 6.1.
