Abstract
A kind of method utilizing recovery ferrum, steel cuttings to prepare composite metal plate, belongs to composite metal plate preparing technical field, and feature is to comprise the steps: that (1) utilizes corrosion resistant plate or carbon steel sheet to be welded into the rectangular box of an opening；(2) carry out rectangular box inner surface polishing, clean, be dried, to visible metallic matrix；(3) scrap iron, steel cuttings are carried out defat, cleans, be dried, remove surface fluid and oxide layer；(4) treated scrap iron, steel cuttings are encased in rectangular box, are enriched by mould, by the open side soldering and sealing of rectangular box, and leave aspirating hole, shut after evacuation in casing；(5) by fill out be filled with ferrum, steel cuttings evacuation after the good rectangular box of soldering and sealing put into heating furnace and be heated to 1000 ~ 1250 DEG C, enter rolling through de-scaling after coming out of the stove, become to meet the composite plate of size requirements through multi-pass rolling.Advantage is compared with the prior art: can ensure that the flakiness ratio of composite plate, controls the thickness accounting of surface metal-layer and iron filings layer, and production stability is good, low cost.
Description
Technical field
The invention belongs to composite metal plate preparing technical field, be specifically related to one and utilize recovery ferrum, steel cuttings to prepare metal composite
The method of plate.
Background technology
Ferrum, steel cuttings mainly include car bits, milling bits, drilling cuttings etc., are to machine inevitable waste material, along with industrial circle is to environment
Require improves constantly, and iron filings recovery and utilization technology becomes the important research direction in energy-conserving and environment-protective field.Traditional method includes:
The ferrum, the steel cuttings that reclaim melt down melting, briquette forming, powder metallurgy, chemical industry extraction etc..The most predominantly melt down melting, not only disappear
Consume substantial amounts of energy, the burning of metal also can have been caused to run off, amplification quantity dusty gas side by side.
The production method of complex plate strip maturation mainly includes Rolling compund, rolling casting bonding and Explosion composite etc..Blast is multiple
The defects such as legal existence faying face oxide is more, noise big, potential safety hazard, production efficiency are low.For rustless steel or carbon steel/ferrum
Or for steel cuttings is compound, roll-bonding method has that energy resource consumption is few, safety is high, production efficiency high.
Composite metal plate can play the advantage of constituent element metal material, saves metal material, and the present invention utilizes this feature,
Corrosion resistant plate or carbon steel sheet are combined with ferrum, steel cuttings, can by use solid phase recovery in the way of to industry scrap again with, relatively
In the method that tradition melts down melting, it is achieved farthest economize on resources and reduce environmental pollution.
Patent " preparation method of a kind of stainless steel/carbon chip core composite plate " (Authorization Notice No.: CN 102553959
B) method proposing to use stainless steel tube and carbon steel chip to prepare composite plate, but the method has the disadvantage that (1) uses steel pipe
After becoming strip as blank rolling, stainless steel layer uneven thickness is thick in intermediate thin both sides；(2) use steel pipe as blank, rolled piece
Cross section is changed to rectangle from circle, and its rolling pass is limited with flakiness ratio；(3) rolled piece blank cross section is that circle causes rolling stable
Property is poor；(4) stainless steel tube cost is higher.
Summary of the invention
It is an object of the invention to provide a kind of method that ferrum is reclaimed in new utilizing, composite metal plate prepared by steel cuttings, can overcome existing
Defect with the presence of technology.
The present invention is achieved in that and it is characterized in that preparation method is as follows:
(1) as it is shown in figure 1, utilize corrosion resistant plate or carbon steel sheet to be welded into the rectangular box of an opening；
(2) carry out the inner surface of above-mentioned casing polishing, clean, be dried, until visible metallic matrix；
(3) ferrum, steel cuttings are carried out defat, cleans, be dried, remove fluid and the oxide layer of remained on surface；
(4) above-mentioned treated ferrum, steel cuttings are encased in above-mentioned rectangular box, and are under high pressure incited somebody to action by particular manufacturing craft
It enriches (as shown in Figure 2), by the open side soldering and sealing of rectangular box, and leaves aspirating hole, shuts after evacuation in casing；
(5) casing that after above-mentioned filling being expired ferrum, steel cuttings evacuation, soldering and sealing is good is put into and is heated to 1000 ~ 1250 in heating furnace
DEG C, enter rolling through de-scaling after coming out of the stove, become composite finished product sheet material through multi-pass rolling.
Advantage of the present invention and good effect be:
(1) the mode large-scale recovery industry scrap using solid phase to reclaim, relatively conventional melts down melting mode, decreases metal combustion
Burn loss, avoid dusty gas discharge.
(2) use the mode of hot rolling to produce rustless steel or carbon steel/ferrum, steel cuttings composite plate, dissimilar metal can not only be realized
Metallurgical binding, and be capable of ferrum, the metallurgical binding of steel cuttings self, reach higher requirement of strength.
(3) use corrosion resistant plate or carbon steel sheet to be welded into rectangular box, it is ensured that the flakiness ratio of composite plate, control flexibly
Surface metal-layer and the thickness accounting of iron filings layer, low cost, stability is strong, beneficially industrialized production.

Detailed description of the invention
Embodiment
Raw material prepares: the steel cuttings produced after using 304 corrosion resistant plates and bolt tapping is raw material, the rustless steel thickness of slab of employing
Spending is 2mm, and the rectangular box of welding is as it is shown in figure 1, the long 100mm of casing, wide 50mm, thick 10mm, and welding is front to rustless steel casing
Inner surface is carried out, dries, is polishing to visible metallic matrix.To steel scrap bits carry out defat, clean, be dried, fully remove steel
Bits surface fluid and oxide layer；
As in figure 2 it is shown, for preventing stainless steel rectangular box deformation, put it in mould 3, steel cuttings be encased in rectangular box 1
In, by briquetting 2, steel cuttings is tamped, reach the consistency of regulation, by populated rectangular box soldering and sealing, evacuation, prevent ferrum
Oxidation is produced during bits high-temperature heating；
By the above-mentioned stainless steel rectangular casing prepared, put into and heating furnace is heated to 1200 DEG C, through three passages after coming out of the stove
Reciprocal rolling, the first reduction in pass is 3mm, and the drafts of the second passage is 2mm, and the drafts of the 3rd passage is 1mm,
Obtain rustless steel/steel cuttings composite plate that finished product thickness is 4 mm eventually；
Again through smooth aligning, surface process, cutting head cutting tail, scale, heat treatment reach the needs of finished product sheet material.
