[Summary] article chat cheerfully heat treatment is energy-saving the application in actual production, the analysis discussed heat treatment energy-saving in the technology, manage the means method that go up. Make heat treatment technology is achieved energy-saving, decrease a platoon, high grade, efficient target. Keyword: Heat treatment is energy-saving, technological process, system, management produces my company is the manufacturer that produces project machine, the component with mechanical very much trade is the mechanical condition that should obtain a design through heat treatment ability, develop the property of material adequately, assure product quality, the class level that raises mechanical part in the market competition ability. I manage is 2005 the bottom establishs department of heat treatment career formally, in program initial stage, act on energy-saving the principle that decreases a platoon is right distribution of heat treatment facilities, technological process, power source equipment and quench cooling system undertook optimizing permutation assorted, come down surely with the formal compasses of the file. Here place narrate heat treatment is energy-saving respect, basically comprise by the element of a few respects: 1: The workpiece that heat treatment technological process lets whether effectively be handled achieves the technical requirement that its design, and with inferior cost. 2: Whether did heat treatment equipment get effective reasonable use in move, for instance successional production, equipment waits for work time to decrease. And without additional hot loss. 3: Heat treatment operates personnel, engineering technology member, reach manufacturing administrator to whether be communicated good, everybody can get active management and organization are produced. One, heat treatment craft calculates in conventional technology time: The T in T=K*A*D type is heat time, k is the coefficient that install furnace, a is heat coefficient, d is workpiece effective ply, actually we are in actual production, it is according to working before effective ply comes to experience and workpiece commonly time of computational heat preservation, when large quantities of quantities with respect to the basis practical experience or the igneous color that are observation work, this basically reacts go up in carbon steel and low-alloy steel, because carbon steel does not have alloying element and carbide,this is, do not need long heat preservation is even austenite changes a course. Low-alloy steel conducts heat because of its coefficient and carbon steel are basic and similar, by its basically significant measure decides so workpiece heats up time fully, to the sheet in production workpiece, already achieved craft set when furnace temperature when the value, that is to say when workpiece surface already achieved craft temperature to be worth, workpiece already was burned fully, not again additional increase heat preservation time, this is us often say " 0 " heat preservation heats. When be being produced to large quantities of quantities, we can heat first commonly furnace, to lukewarm hind put work again, when waiting for furnace temperature to achieve craft time again, it is certain to be added again spend time equably, can shorten relatively so craft is periodic, managing the sources of energy and reduce cost. Alloy structure steel (40Cr, 35CrMo, 42CrMo) wait, because a few alloying element were added in its material, heating the time that we should make change need equably in carbide certain in the process, be about many a little bit for opposite carbon steel so time, general the 60%-80% left and right sides that we also should get on in conventional technology time, such doing can shorten steel heat in high temperature time, deflection also decreases relatively a bit, abstruse family name changes grain relatively fine small, after quenching, attainable petty martensite is organized, its machinery function also gets rising certainly, this also is the result that worker of our heat treatment wants to achieve. 2, the spare parts installs furnace 　 1: In actual production, when work measure finite circumstance falls, independent arrangement furnace second be not of be to one's profit, below this kind of circumstance, we are OK a different workpiece, different material, in its the situation with craft roughly same parameter falls can mix install one furnace, be like Cr12MoV and 8407 or H13, 40Cr and 42CrMo also are same. Its quench temperature is roughly identical, what can get installing furnace measuring so is contented, it is with manage when temper temperature is identical, different spare parts, different material can mix one furnace, temper time can be carried out by the longest temper time. 2: Heat treatment clamping apparatus, actually a lot of products of our company are not close identical, and the quantity is not very much, but increasing heat treatment tool occasionally to reduce deflection, such I a lot of moment need not heat-resisting stainless steel, mostly common mild steel is replaced, basically be material price low, still having an amount is not very much. 3, medium of heat treatment refrigeration because my company's very much mechanical component is alloy structure steel, quench in the consideration so when medium. I choose to use aqueous solution, aqueous solution quenchs with respect to the carbon in avoiding big diameter low-alloy steel uses hardness of oily temper by dipping in water to be worth a likelihood in heat treatment short of, with the circumstance of Shui Cuiyi craze, water-solubility synthesis quenchs fluid is applied to especially low, induction of medium carbon steel reachs big to quench, water-solubility synthesis quenchs fluid is applied to especially low, induction of medium carbon steel reachs big to quench, wait through adjusting chroma, can get different cooling rate, quench workpiece is shining and have short-term and antirust effect, can not clean direct temper, without lampblack. Without lampblack, not it is combustion, dangerous to do not have fire, improve work environment. Not easy ageing, degenerative, service life is long, taste at oil relatively for. Cost is relative also less. 1, temper craft: Temper craft is the furnace beyond heat that should decide to want to use according to the temper temperature of the spare parts, common law is temperature of spare parts temper under furnace more than hot temperature is controlled 300 degrees, the furnace after such word workpiece enters furnace achieves set of temper craft temperature very quickly to be worth, still have temper for many times to compare temper to be close friends, the constituent property that obtains in 2 such temper when large quantities of quantities are produced so compares temper to be close friends, cost also decreases accordingly a lot of. 2, equipment safeguards and maintain: Our aborning should maintain facility regularly, check the chamber of a stove or furnace, the sealing of furnace door. Instrument appearance wants related distribution box fixed calibration and safeguard, reduce what cause because of electric equipment breakdown to stop the loss that furnace produces. Each relevant operation equipment is like stage car, the loss that the maintenance of drive a vehicle reduces inconvenience of furnace of pass in and out and causes. 3, the control of heat treatment quality: When actually workpiece is having heat treatment, its itself is in namely energy-saving, if a workpiece did not pass effective and reasonable heat treatment, then this spare parts uses time limit also very won't long, component early failure should make new assembly change without fail, must again so raw material of quiet waste time and machining man-hour, related to other charge. Effective and reasonable heat treatment can make the growth of the service life twice of workpiece. Heat treatment quality is so good can avoid workpiece early failure, can avoid repair of workpiece heat treatment (normalizing, new oil temper, corrective, go stress temper) wait for a series of programs. So our country 70 time have 20 centuries a catchword: "Do well heat treatment, spare parts a few " . Awaiting is with craft management is concerned when heat treatment is a lot of more energy-saving, reasonable arrangement works, reduce time stopping furnace, the time level that puts level of furnace heating up time in the petty gain that use phone undertakes, craft of a lot of moment is carried out reach the designated position to be concerned with management, the company should establish procedure and equipment operation standard strictly, reach relevant technology level. On manufacturing arrangement, want as far as possible production of batch full load, install what furnace measures to should spell furnace not quite, had made the preparation before each heat treatment works ahead of schedule. Regular examination heat treatment the moving circumstance of each equipment. Conclusion raises the vocational level of heat treatment personnel actively, operate level and relevant working consciousness, raise the working manner of heat treatment personnel. Because a lot of time are final,payoff still is " person " . In relevant hardware unalterable circumstance falls, the working manner that serves as personnel is software. We can make relevant system, execute byelaw of rewards and punishment, the specific power consumption in statistic and assessment production, in the light of undesirable undertake rectifying and reform administrative. Energy-saving very significant position is in in decreasing a platoon to work in us, how managing specific power consumption, improve manufacturing efficiency, reduce cost, in the market competitive backbone stands from already brand. Production and technical level of management rise is to carry out technology development, it is the important step that the company grows. Energy-saving consciousness is made from me, make from now, the every little bit from inside the job is made. Make heat treatment technology is achieved energy-saving, decrease a platoon, high grade, efficient target. Also make produce character to measure quality, cost control is in certain class in the market. CNC Milling CNC Machining
