Embodiment
Below, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, metal surface treating method of the present invention, comprising: the step removing the dirt after washing of metallic substance; After washing, when described metallic substance carries out wire drawing by wortle, in order to improve lubricant effect, protecting the surface of described metallic substance and carry (carrier (pick-up)) various lubricant, form the step of an alkali metal salt pre-treatment epithelium (hereinafter referred to as " an alkali metal salt epithelium ") on the surface of described metallic substance; And drying step.
Wire rod selected by metallic substance.Wire rod refers to the wire rod (WireRod) being manufactured various line by Wire Drawing.Wire rod is fabricated to the diameter with 5.5mm-32mm, manufactured the drawing process of the fine rule of wanted shape and size by the hole pull-out through wortle and be manufactured to steel wire, iron wire, piano wire.
Wire rod can be formed hard dirt on surface by after hot rolling, in order to Wire Drawing needs to remove dirt.Wire rod is by after hot rolling, and need to heat-treat to obtain physical properties (hardness and toughness), the wire rod of heat-treating also forms dirt on surface, therefore in order to Wire Drawing also needs to remove dirt.Dirt is the oxide compound produced at wire surface, can affect Wire Drawing when not removing.
At least one method that dirt is removed can be selected from chemical pickling operation, electrolytic pickling operation, physics derust in operation.
Pickling process is wire rod is immersed to the operation that the specified time such as hydrochloric acid, sulfuric acid removes dirt, and physics derusts operation for carrying out de-scaling (scalebreaker) or spraying the operation that hard particles projectile and high pressure water remove the dirt of wire surface on the surface of wire rod.
The concentration that the dirt of pickling process removes the Acidwash solution by increasing hydrochloric acid, sulfuric acid, nitric acid etc. improves clearance.
Wash after removing the dirt of wire surface, and form an alkali metal salt epithelium on the surface of wire rod.Carry out drying after forming an alkali metal salt epithelium, then carry out Wire Drawing.
During Wire Drawing, most important condition is for guarantee wire-drawing workability by lubricant effect.Wire Drawing is generally High-speed machining, therefore, adds and easily causes man-hour temperature to rise, reduce oil body or cause the floating and rupture of oil film of powder lubricant.And Wire Drawing is attended by high temperature, therefore, because the friction of wortle and wire rod easily forms adhesion at wortle, and easily produce flaw on the surface of wire rod because of described adhesion or be difficult to carry out viscous deformation smoothly.
When Wire Drawing, the friction because of the High Temperature High Pressure produced between wortle and wire rod causes wire surface damaged, in order to prevent breakage and complete viscous deformation smoothly, forms epithelium at wire surface.
Epithelium is an alkali metal salt epithelium.An alkali metal salt epithelium is be immersed to by the wire rod of washing in the metal conditioner containing an alkali metal salt reactant and additive, thus is adhered to wire surface.
In addition, also have the gunite at wire surface metal injection surface treatment agent, the squeegee process with brush brushing, method etc. with roll brushing, wire rod is immersed to and is equipped with in the groove of metal conditioner by preferred employing, thus in the sedimentation of wire rod surface bonding metal conditioner.
An alkali metal salt epithelium improves oilness in Wire Drawing, thus can carry out viscous deformation smoothly.
The bonding amount (thickness) of an alkali metal salt epithelium is preferably 5-30g/ ㎡.
The bonding amount of an alkali metal salt epithelium is relevant with Wire Drawing, the solidity to corrosion of epithelium and wear resistance can not be guaranteed when bonding amount is less than 5g/ ㎡ and in Wire Drawing, be difficult to guarantee oilness, when being greater than 30g/ ㎡, because too much epithelium causes the close property of epithelium itself to reduce, reduce wire-drawing workability simultaneously.
The epithelium of optimum regime is formed when the bonding amount of an alkali metal salt epithelium is 10g/ ㎡.
The quality of its an alkali metal salt reactant of metal conditioner and additive is 10:90-90:10 than scope.Preferably, the quality of its an alkali metal salt reactant of metal conditioner and additive is 60:40-70:30 than scope.
An alkali metal salt reactant is used for forming epithelium at wire surface.
Additive works to improve the solidity to corrosion of epithelium and increases the bonding amount of epithelium or lubricant.Containing additive only with an alkali metal salt reactant when wire surface forms epithelium, can epithelium be formed but be difficult to adjust bonding amount and uneven, produce iron rust at wire rod and be difficult to guarantee solidity to corrosion.
When the mass ratio of an alkali metal salt reactant and additive is less than 60:40, although can epithelium be formed, but the quantity not sufficient of an alkali metal salt reactant and be difficult to be formed the epithelium of optimal morphology, when more than 70:30 quality than time, carry the scarce capacity of lubricant because additive is not enough and be difficult to be formed the epithelium of optimal morphology.
When the mass ratio of an alkali metal salt reactant and additive is less than 10:90, be difficult to guarantee the bonding amount of epithelium, when more than 90:10 quality than time, be difficult to the epithelium forming optimal morphology because additive is not enough, and be difficult to bonding epithelium equably.
