Abstract
The invention belongs to alloy powder used for improving harness, corrosion resistance and abrasive resistance of metal surface materials and prolonging service life of devices in metallurgical industries, and particularly relates to chromium nickel manganese alloy self-fluxing powder. The chromium nickel manganese alloy self-fluxing powder is characterized in that chromium nickel manganese compound is formed by the following raw materials, by weight, 70% of chromium, 10% of nickel and 20% of manganese. After the chromium, the nickel and the manganese are mixed, the powder is prepared by the following components, by size, 20% of the chromium nickel manganese compound, 3.00% of boron (B), 12% of wolframium (W), and the rest is the size of iron powder. The chromium nickel manganese alloy self-fluxing powder is applied to devices in a coal-mining industry and a cement industry, the corrosion resistance, the abrasive resistance and the hardness are greatly improved, meanwhile, time is saved and production efficiency is improved, and therefore profit is improved. According to the chromium nickel manganese alloy self-fluxing powder, the surface hardness of alloyed metal materials is larger than 58HRC, and the abrasive resistance is improved by 30-50 times than original metal materials.
Description
Technical field
The invention belongs to hardness, the raising corrosion-resistant and wearability of metallurgy industry in order to improve metal surface material, the alloy powder that extension device uses is particularly about a kind of chromium nickel-manganese Self-fusing powder.
Background technology
Along with national economy is fast-developing, Coal Industry and cement sectors demand also increase day by day, and construction of coal mine is at large-scale development, the colliery with column demand every year all up to ten thousand left and right, cement plant roll more or less a hundred, so maintenance market is very large.Increasing utilizes our alloy powder cladding and technique for overlaying, column repair in process and use in the weld deposit process of roll alloy powder have chromium nickel manganese powder end proportion low weight in weld deposit process chromium nickel manganese powder end fly upward the content that has reduced chromium, nickel, manganese and can not make it reach optimum performance, for this reason our specialize the welding block of chromium nickel-manganese Self-fusing powder.
Summary of the invention
The purpose of this invention is to provide a kind of chromium nickel-manganese Self-fusing powder that contains, it can overcome above deficiency, improves hardness, corrosion and the wearability of metal surface material, the service life of extension device.
For achieving the above object, the technical solution used in the present invention is: a kind of chromium nickel-manganese Self-fusing powder is provided, it is characterized in that: it is synthetic by the raw material of following percentage by weight; Chromium nickel manganese is according to chromium 70%; Nickel 10%; Manganese 20% weight ratio is mixed; After mixing more by volume: in whole volume: the volume of chromium nickel manganese accounts for 20%, B boron 3.00%, 12% preparation of W tungsten, and all the other are iron powder volumes.
Above-mentioned a kind of chromium nickel-manganese Self-fusing powder preparing process process is:
1, chromium nickel manganese is pressed according to chromium 70%; Nickel 10%; Manganese 20% weight ratio was mixed, and mixture is under-0.08 condition in vacuum, with insulation at the temperature of 120 ± 5 ℃ two hours;
2, iron powder was also under-0.08 condition in vacuum, with insulation at the temperature of 120 ± 5 ℃ two hours;
3, pass through weight=proportion * stereometer and calculate 20% preparation that the volume of chromium nickel manganese accounts for whole volume;
4, add B boron 3.00% by the cumulative volume ratio; W tungsten 12.00%; Chromium nickel manganese accounts for 20% of whole volume, and all the other are Fe iron powder mix;
5,4 mixed chromium nickel manganese powders ends, iron powder and boron powder and tungsten powder powder were mixed 8-12 hours in the three-dimensional rotation batch mixer;
6, then mixed chromium nickel manganese powder end, iron powder, boron powder and tungsten powder are put into ball mill-24 ℃ to-30 ℃ ball millings 8-10 hours;
7, the chromium nickel-manganese Self-fusing powder after the taking-up ball milling is under-0.08 condition in vacuum, gets final product in two hours with insulation at the temperature of 120 ± 5 ℃.
The present invention compared with prior art, advantage and effect that the present invention has are as follows:
