Description
Technical field
The present invention relates to welding materials and field of metallurgy, specifically about a kind of iron-based strip based on double roller continuous casting technology
The manufacturing method of solder.
Background technology
The type of stainless steel industrially used in recent years is transitioned into ferrite from austenite, under this situation, mesh
For nickel-based solder used in preceding soldering stainless steel when for ferrite-group stainless steel base material, the tissue of the base material after soldering is coarse,
The strength reduction of brazed components.The tissue coarsening is the contained Cr contents of nickel-based solder, when the weight shared by Cr elements
Percentage be less than 20% when organize coarsening phenomenon be improved significantly.In addition, due to the price of nickel ingot and chromium ingot in recent years
Go up, the price of nickel solder rises therewith, and one kind is especially thirsted in brazing material market reduces nickel content or other low cost prickers
Expect the development of type, but important element of the nickel element as nickel-based solder, soldered fitting have good corrosion resistance with
The reduction of high-temperature oxidation resistance, content is limited.
Iron-based solder has good wetability in stainless steel surface and high connects as a kind of new type high temperature solder
Head intensity and high temperature corrosion resistance, price is well below nickel-based solder.The solder can be widely used in different types of heat exchange
Device and catalyst, this will save the cost of about 30%-40% than traditional nickel-based solder.Existing iron-based pricker on the market
Material mainly exists with powder or pasta physical aspect, applied to gas recirculation system (Exhaust Gas
Recirculation, EGR) etc. equipment when process operability it is poor, dosage is difficult to accurately control, this can all cause unnecessary
Waste improves production cost.For this purpose, enterprise proposes tight demand to thin ribbon shaped, sheet solder.
There are many techniques for strip forming technique, and conventional strip solder preparation method is rolled by ingot casting, extruding, multiple tracks
Some row complex steps such as system, annealing are made, the shortcomings that this preparation method be rolling performance requirement to hot-rolling mill very
Height, traditional hot-rolling mill cannot be satisfied, and followed by pass through multiple working procedure, increase production cost.And double roller continuous casting is utilized two
Molten metal direct pouring at strip, can be saved the processes such as high-temperature heating and course of hot rolling by the crystallization roll of a rotation, be a kind of
The short route newly net forming technology being worthy to be popularized, has many advantages, such as environmentally friendly, energy saving, inexpensive.Double roller continuous casting have make melt
The characteristics of solder quickly solidifies is up to 102-104DEG C/cooling velocity of s is far longer than the cooling speed of conventional continuous casting heavy slab
Degree, can give full play to the superiority of flash set technology, be applied to the difficult-to-machine materials such as silicon steel, electrical sheet, cast iron at present
Preparation process.The crystallization roll rotated using two can realize two-sided directional solidification to melt solder to a certain extent, can obtain
Obtain the iron-based strip with flourishing columanar structure.Compared with traditional continuous casting process, double roller continuous casting prepare iron-based solder have with
Lower advantage：(1) operation of rolling is completed while solidification, the huge cogging of investment can be saved, simplify production process, section
The about energy, environmental protection, greatly shorten production procedure, raise labour productivity.According to relevant report, double roller continuous casting technique is used
The average outgo per ton of raw material needed for technology is only the 50% of traditional handicraft, and floor space is only the 24% of traditional handicraft, required
Staff is the 13% of traditional handicraft；(2) quick solidification of the melt brazing filler metal alloy between double roller promotes the formation of metastable phase, expands
Big solid solubility, has refined tissue, to substantially improve material property；(3) the characteristics of iron-based solder is quenched and solidified connects with double roller
Casting process matches.

The temperature of melt solder need to be controlled when melt solder is cast in tundish, the temperature of melt solder is excessively high, easily
In leading to bleed-out accident；The temperature of melt solder is too low, easily causes and rolls card accident.
In casting process, the rotating speed of crystallization roll is too fast or can all be impacted slowly to the stability of casting process excessively.
Cast Strip volume carries out warm-rolling after must be cooled to 200-300 DEG C in air, if temperature is too low, the plasticity of Cast Strip compared with
Difference is prone to crackle during the rolling process.If temperature is excessively high, strip surface oxidation is serious, has aggravated subsequent process
Load.The purpose that warm-rolling is carried out to Cast Strip is to improve plasticity, plate shape and the surface quality of Cast Strip.
The advantage of the invention is that：
