Description
Technical field
The present invention relates to metal heat treatmet technology, specifically be meant the single furnace multiple cycle temper tempering heat treatment method of double metal saw belt.
Background technology
The inner quality of double metal saw belt and thermal treatment process technology horizontal relationship are very big, all attach great importance to both at home and abroad constantly bringing forth new ideas and improving of biobelt thermal treatment process technology level.Because the double metal saw belt belt body is thin, two kinds of materials are compound, after the processing, adopted nitrogen protection specially quench, tempering process, thereby obtain the different hardness qualities of two kinds of materials and the effects of light.This is very success and advanced manufacturing technology of double metal saw belt, and at present, this technology and equipment technology are very ripe, for crucial effect has been played in the development of band saw cutting technique and product technology.
But the thermal treatment process of double metal saw belt and equipment still adopt towed quenching furnance and three tempered discontinuous runnings of conventional well formula tempering stove mode before 20 years now.This processing method, energy consumption is higher, the production cycle is long, fluctuation is arranged during product performance.Tail fin, cutter bend even decarburization happens occasionally; This activity time is long in addition, occupation area of equipment is big, and existing place, equipment are difficult to enhance productivity again, production capacity.For this reason, how to improve this process capability, promote tempering quality, particularly make full use of the rapid steel performance characteristics, by tempering, reach age hardening effect, improve tooth portion hardness to greatest extent, promote the saw band quality is the target that our same industry two is pursued during the last ten years always.
Summary of the invention
The technical problem to be solved in the present invention is, defective at the prior art existence, a kind of single furnace multiple cycle temper tempering heat treatment method of double metal saw belt is proposed, the periodic tempering of its former relatively well formula tempering stove can significantly cut down the consumption of energy, reduce labor intensity, and can significantly shorten the production cycle, and the good stability of saw band quality product.
Technical scheme of the present invention is, the single furnace multiple cycle temper tempering heat treatment method of described double metal saw belt is, two ends at a tempering stove are provided with one or more rotary disk respectively, continuously the double metal saw belt of operation enters the stove from tempering stove one end, and this double metal saw belt comes out by tempering stove and by the other end of tempering stove; Enter described tempering stove once more after first rotary disk revolution of the described the other end of described then double metal saw belt pile warp tempering stove, bring out by tempering stove and by described one of tempering stove for the second time; Described double metal saw belt also enters tempering stove again and passes through tempering stove for the third time after the revolution of second rotary disk of the described end of pile warp tempering stove again, comes out from the described the other end of tempering stove again; And at every turn when tempering stove comes out all through one section cooling zone.Double metal saw belt is a secondary time or more than the secondary by the total degree that passes through of tempering stove by tempering stove and through revolution once more; Double metal saw belt is packed up by receiving mechanism after tempering stove comes out for the last time.
Below the present invention made further specify.
The present invention is after thin, the long characteristic of fully having analyzed rapid steel heat treatment performance characteristics and two kinds of material compound biobelt products and product performance requirement, a kind of optimization thermal treatment process that proposes, it adopts continuously, repeatedly tempering mode, the periodic tempering of former relatively well formula tempering stove has reduced energy consumption 70%, alleviate labour intensity, and shortened 17 hours production cycles (single-deck saw band); Because what adopt is continuous tempering, has guaranteed the stability of saw band quality product; Tempering has realized the quick cooling after the insulation continuously, has given full play to the secondary hardening effect of tooth material rapid steel, improves hardness, red hardness and the wear resisting property of saw band crown.For the saw band back, the fast cold generation that reduces temper brittleness, the fatigue lifetime of having improved saw band greatly; Thereby the comprehensive sawing ability of the saw band product of explained hereafter of the present invention have greatly improved (former relatively technology improves 20---30%).And hot aligned effect has been played in tempering continuously, has reduced the distortion (tail sticks up with cutter curved) of saw band, realizes substantially without the rolling alignment; If tempering can realize that also the complete non-oxidation decarburization of saw band product heat treatment process phenomenon takes place in protective atmospheres such as nitrogen, its appearance is a silver bright color, and is very attractive in appearance, also alleviated the sandblast difficulty.
As known from the above, the present invention is the single furnace multiple cycle temper tempering heat treatment method of double metal saw belt, and the periodic tempering of its former relatively well formula tempering stove has significantly reduced energy consumption, has alleviated labour intensity, and significantly shortened the production cycle, and the good stability of saw band quality product.
