Description
Technical field
The present invention relates to the production technologies of anticorrosive anti-loosening stainless steel room staple line.
Background technique
Room staple line is the nail material used on roof wood, domestic at present this for room nail almost without using
Raw material, currently leading country to be used is France, Germany, Japan, their house mainly uses wood materials, in order to solid
Determine wood materials, the spike of abnormity is needed to fix, it is anti-loosening anti-since these materials need the time limit time to be used longer
Corrosion demand is higher, it is therefore desirable to which raw material have preferable physical property and chemical property.
There is the product of the country such as Japan, Germany, France in current external main competition country, due to production equipment low precision
Different, production does not have unified standard standard, the difference of the factors such as temperature, use environment, service life by each area, therefore
The room staple line raw material of production is produced according to customer requirement, in order to enhance the international competitiveness of Products, mainly from anti-corruption
It is studied in terms of corrosion and internal austenite structure two.
In order to enhance similar product competitiveness, accelerates speed of production, improves the corrosion resistance of product and promoted in production
The feature of environmental protection is the main trend of current room staple line development.
Summary of the invention
It is an object of the present invention to overcome defect existing in the prior art, anticorrosive anti-loosening stainless steel room nail is provided
The production technology of line saves hydroelectric resources, realizes the target of clean manufacturing；The staple line of output does not need to be thrown after continuous annealing
Light polishing, saves operating procedure, reduces production energy consumption, improve operating efficiency；It is synchronous with drying to be able to achieve film agent
Property, annealing efficiency is improved, energy waste is reduced.
To achieve the above object, the technical scheme is to design a kind of lifes of anticorrosive anti-loosening stainless steel room staple line
Production. art comprises the technical steps that:
S1, thick pumping: epithelium processing and drying and processing are successively carried out to the STAINLESS STEEL WIRE through wire drawing machine drawing, then by more
Head continuous drawing machine is to take-up after the STAINLESS STEEL WIRE progress redraing after drying；
S2, continuous bright annealing: to cleaned after the STAINLESS STEEL WIRE unwrapping wire after S1 step process with metal cleaner or acid
It washes, then take-up after continuous bright heat treatment after washing drying；
S3, finishing drawing: with single head drawbench to carrying out drawing, drawing after the STAINLESS STEEL WIRE unwrapping wire after S2 step process
STAINLESS STEEL WIRE is cleaned after drawing by rhinestone mould in the process；
S4, annealing: carrying out online coating treatment to the STAINLESS STEEL WIRE after S3 step process with film agent, then with drying
Then machine continuous drying, take-up after drying are examined, are packed, storage.
Further technical solution is that the original line footpath of STAINLESS STEEL WIRE is 5.5~10.0mm, in the S1 step,
STAINLESS STEEL WIRE is set at the uniform velocity to pass through Metal Surface Phosphate Treating Area and drying oven by wire drawing machine, the furnace temperature of drying oven is 150 ± 50 DEG C；It is described secondary
Drawing is that 2~3 passages are rough, and the draft of first of use 25%~30%, each passage draft subtracts than the first passage later
Face rate reduces 5%~8%.
Further technical solution is in S2 step, to be connected using continuous bright heat-treatment furnace to STAINLESS STEEL WIRE
Continuous brightness heat treatment, 1100 ± 50 DEG C of furnace temperature, continuous bright is passed through ammonia in its boiler tube of continuous bright heat-treatment furnace when being heat-treated
Decompose gas.The speed of heat treatment is depending on steel wire diameter.After being passed through ammonolysis craft in boiler tube, 75%H2,25%N2 mixed gas
Steam is protected, take-up enters subsequent processing.
Further technical solution is, is 5%- by the draft that rhinestone mould carries out drawing in the S3 step
10%.Steel wire passes through rhinestone mould by the draft small deformation degree of 5%-10%, and product qualification rate is higher, qualification rate
99.5%, mold is gently drawn with single head drawbench, is cleaned up using clear thin case, into subsequent processing.
Further technical solution is, in S2 step, to pickling after STAINLESS STEEL WIRE unwrapping wire, pickling process includes as follows
Step: pre- pickling is first carried out to STAINLESS STEEL WIRE using sulfuric acid, then rinses, then nitration mixture pickling, is then used after secondary rinsing
High pressure water rinse, be then successively passivated, three times rinsing and neutralisation treatment；The mass fraction of the sulfuric acid is 65%, in institute
State in nitration mixture acid pickling step, nitration mixture pickling solution be use mass fraction for 65% sulfuric acid, mass fraction be 30% hydrofluoric acid
The nitration mixture pickling solution prepared with water, sulfuric acid is 100~110g/L in nitration mixture washing lotion, and hydrofluoric acid is 1~3g/L.Replacing all was originally
In such a way that the nitration mixture pickling solution of nitric acid and hydrofluoric acid carries out pickling, and sulfuric acid is used, this avoid produce in acid cleaning process
Nitrate, nitrite and the NO of raw pollution environmentXDeng.
Further technical solution is that its each ingredient of STAINLESS STEEL WIRE is according to mass percent are as follows: containing carbon 0.040%,
Silicon 0.43%, manganese 1.23%, nickel 8.44%, chromium 17.52%, nitrogen 0.0258%, copper 2.12%.The stainless steel wire matched in this way
The forming amount of material, strain-induced martensite α ' phase (magnetism) is more, reaches 17% or so, improves the stability of austenite, has preferably
Cold-heading.
The step of further technical solution is, in S2 step, is heat-treated as on-line solution mode, heat treatment is not
The steel wire rod that becomes rusty is rolled up air-cooled using control chilling roller road slow cooling to 600 ± 30 DEG C of collection after spinning.After on-line solution processing, grain size reaches 8
Grade；Not reducing how much tensile strength but improves performance, can deep processing, and do not find carbide crystal boundary be precipitated, to resistance to crystalline substance
Between corrosivity there is no adverse effect.
The advantages and beneficial effects of the present invention are: substituting original one vehicle of one man operation, operation using the operation simultaneously of three vehicles
Improved efficiency 300%；It is processed by the way of single tube two-wire, between being controlled between two stainless steel wires by lead frame
Away from, so that will not influence each other between the two, raising production efficiency；Introduced from Japan metal cleaner four reaches board SD-7, instead of original
Some point solution acid cleaning process save hydroelectric resources, realize the target of clean manufacturing；It is opened using diamond mold, is continuously moved back
The staple line of output does not need to carry out polishing grinding after fire, saves operating procedure, reduces production energy consumption, improves operation effect
Rate；Secondary epithelium Processing System Design realizes the synchronism of film agent and drying, improves annealing efficiency, reduces energy waste.Steel
Silk passes through rhinestone mould by the draft small deformation degree of 5%-10%, and product qualification rate is higher, qualification rate 99.5%；It takes
Generation was all originally by the way of carrying out pickling using the nitration mixture pickling solution of nitric acid and hydrofluoric acid, and using sulfuric acid, this avoid acid
Nitrate, nitrite and the NO of pollution environment are generated during washingXDeng.The forming amount of strain-induced martensite α ' phase (magnetism) compared with
It is more, reach 17% or so, improve the stability of austenite, there is preferable cold-heading.After on-line solution processing, grain size reaches
8 grades；Not reducing how much tensile strength but improves performance, can deep processing, and do not find carbide crystal boundary be precipitated, to resistance to crystalline substance
Between corrosivity there is no adverse effect.
