Abstract
The fast hot steel part aluminizing process includes the following steps: deoiling, derusting, washing, surface activating, aiding aluminizing, drying naturally or through stoving, treating with flux, and aluminizing. The process has the advantages of low aluminizing temperature, short aluminizing time, low power consumption and high efficiency, and the low temperature fast aluminizing process makes the aluminized layer possess raised heat resistance, shock stability, fatigue strength, welding performance, corrosion resistance, etc.
Description
Technical field
The present invention relates to the metal heat treatmet technical field, specifically a kind of fast thermal alumetizing technology for steel pieces.
Background technology
Aluminising can improve solidity to corrosion and the thermotolerance of alloy in oxidizing medium and corrosive medium, the steel workpiece of aluminising can match in excellence or beauty in stainless steel in 500 ℃～700 ℃ sulfur-containing medium, for a large amount of stainless steels is saved in petrochemical complex industry, aluminising can increase exponentially the duration of service of turbine blade, and aluminising can increase the high temperature resistant property of iron-based and iron nickel base alloy etc.But the old arts demand high-temperature of traditional aluminising (about 950 ℃～1050 ℃), in the cycle long (more than 6～8 hours), because long-time high temperature, the part easy deformation has a significant impact mechanical property, and stove is short work-ing life, and product cost is increased.And traditional old technology aluminized coating always has the surface brittleness district, and the brittle zone is in flexural deformation, the transportation collision, or add and peel off easily man-hour, produce stress concentration, impel crackle to expand to the aluminized coating depths.Therefore, in using installation process, need the part of bending can't adopt old technology aluminising.
Summary of the invention
The objective of the invention is to improve the temperature height in traditional alumetizing process, power consumption is big, cycle is long, yield poorly, the shortcoming that cost is high is utilized the aluminising of current compensation heating-type, with the method for current compensation, shorten the aluminising cycle, by the aluminium content in the rate of heating control infiltration layer, phase composition and diffusion layer organization are eliminated the surface brittleness district, improved crooked performance, and at the high temperature resistance that keeps old technology infiltration layer, on the basis of wear resistance, simultaneously, improve resistance to corrosion, and kept the fast thermal alumetizing technology for steel pieces of the intensity of former base material machinery.
Fast thermal alumetizing technology for steel pieces of the present invention is as follows:
1. oil removing: the steel part that will ooze is put into air furnace earlier and is heated, and baking was burnt about 20 minutes under 350 ℃～400 ℃ temperature, treats that the aluminising steel piece surface reaches till nothing oil, the drying;
2. rust cleaning: ooze part after the oil removing, take out from process furnace, immerse in the mixing water liquid of industrial sulphuric acid (concentration is 15%) and hydrochloric acid (concentration is 12%), the acid-leaching reaction through 15 minutes can take out when silver gray appears in the surface;
3. clear water is scrubbed: oozed part through after acidleach derusts, got final product in 4～6 minutes with flushing with clean water;
4. surface active: ooze part and after flushing with clean water is good, immerse chromic anhydride (1/1000 concentration) immediately, potassium permanganate (2/1000 concentration), Sodium Nitrite (1.5/1000 concentration), surplus is in the activation solution of water, after reaction in 2～4 minutes, takes out washing;
5. help and ooze: will ooze the part dip in Zirconium tetrafluoride (1/1000 concentration), sodium fluozirconate (1.2/1000 concentration), zirconium anhydride (0.5/1000 concentration) surplus is can after 4 minutes in the quickening liquid of water;
6. oven dry or seasoning;
7. flux is handled: put the part that oozes of airing into aluminum fluoride 10-30%, Sodium Fluoride 10-35%, sodium-chlor remainder, soak in the liquation that temperature is 600 ℃ 1 minute can aluminising;
8. aluminising: enter 1-3% silicon, 0.1-0.3% palladium, 0.01-0.03% cerium, 0.005-0.03% lanthanum immediately through 1 minute steel part of solvent, the aluminium liquid that temperature is 680 ℃ soaks and got final product in 2～4 minutes.
The advantage of fast thermal alumetizing technology for steel pieces of the present invention is: aluminising temperature low (about 680 ℃), and the aluminising time short (2-4 minute), saved the energy, improved efficient.Simultaneously because:
1, the data from experiment relatively draw " low temperature is quick " aluminising novel process, and the heat resistanceheat resistant that has improved Diffusional aluminizing is impacted stability and fatigue strength respectively more than 10%;
2, improved welding property;
3, because the characteristics of " low temperature is quick " have kept the aluminum layer of workpiece surface fully, improved erosion resistance, because of aluminium is subjected to having formed the hard fine and close again AI of one deck after temperature and the atmospheric oxidation
2O
3Protective layer, better the ferro-aluminium layer is played sealing process;
4, evidence: the metal structure before and after the aluminising, conventional mechanical property keep intensity to have no significant change.
Below performance is carried out analysis of experiments:
One, influence of times and mechanism thereof
The aluminising of steel is all carried out in the high temperature austenite district, and aluminium except outside the Pass having with temperature, is gone back relevant with the evolving path of aluminium in austenite in the velocity of diffusion of piece surface during aluminising.Because it is with the type of heating of aluminising and rate of heating and Heating temperature much relations to be arranged that Ovshinsky advances grain refining.50 ℃/second of the quick aluminising rate of heating of electric current, 0.1 ℃/second of the old technology rate of heating of hot aluminising, 10 ℃/second.Under different heating speed, obtain different spread coefficients.
Two, heat shock resistance stability
The aluminising workpiece may suffer thermal shocking when work or repairing installation, the comparative approach of dual mode aluminising is: the aluminising sample is heated to 550 ℃, cold or the water-cooled in chamber then, behind certain so repeatedly number of times, carry out the crackle of metallographicobservation aluminized coating again, the proof of obtaining a result has a surface brittleness district infiltration layer with former diffusion technique aluminising, after the secondary thermal cycle impact, just begin to occur crackle.With the infiltration layer of current compensational method, owing to there is not a surface brittleness district, sensitive less to thermal shocking is after 40 heat shock cycling, also form crackle in infiltration layer.
The CRSM0 steel part sample heat stability test of aluminising
