Abstract
The invention discloses a method for removing an oxide layer on the surface of a nickel-chromium alloy wire rod, which comprises the following steps of: 1) paying off; 2) straightening the wire rod; 3) performing ball blasting; and 4) winding. Compared with the conventional acid washing method, the method has the advantages of complete clearing effect, high clearing speed, small polishing loss, basically no waste material, simple treating process and the like.
Description
Technical field
The present invention relates to metal wire material surface oxide clearance technique field, particularly a kind of technology and method that is used to remove oxide layer on surface of nickel-chromium alloy wire rod.
Background technology
The method that traditional nichrome surface is removed oxide layer generally is to adopt to be mixed with pickle as highly acid chemicals such as hydrofluoric acid, sulfuric acid, hydrochloric acid, nitric acid and to be contained in the corrosion resistant plastic containers, then pending alloy wire is put into to mention after wherein etch a period of time to wash with clear water and dries.This method with pickling removal alloy surface oxide layer has the one-time investment features of smaller, but erosion sediment thickness is difficult to accurate grasp when having the wire rod of cleaning simultaneously, the wire rod loss is big, cleaning speed is slow, efficient is low, it is poor to remove the uniformity, the floating harmful and shortcoming of also wanting the more pickle liquor of neutralisation treatment of the acid mist of generation.If acid waste liquid is not handled and is directly poured sewer into and can cause the pollution that is difficult to remove to surrounding environment in addition.Belong to backward non-environmental protection traditional handicraft so acid wash is removed nickel chromium triangle wire rod surface oxide layer, raising haves much room for improvement.
Summary of the invention
At above defective, the object of the present invention is to provide a kind of being used to remove the method that nickel-chromium alloy wire rod shows oxide layer, be to the oxide layer of the intensive bullet bundle of nickel-chromium alloy wire rod surface impelling by the wire rod shot-blast cleaning machine with the removing metal wire material surface.
1), unwrapping wire technical scheme of the present invention realizes in the following manner: a kind of method that is used to remove oxide layer on surface of nickel-chromium alloy wire rod may further comprise the steps:; 2), wire rod straightening; 3), Shot Blasting; 4), take-up, it is characterized in that:
1), unwrapping wire: pending nickel-chromium alloy wire rod is placed in above the servo-actuated draw drum;
2), wire rod straightening: start power control system, nickel-chromium alloy wire rod enters the wire rod trimmer with speed 70-90M/min;
3), Shot Blasting: nickel-chromium alloy wire rod is drawn the impelling district that sends in the shot-blast cleaning machine machine by the wire rod trimmer, shot wheel in the machine is continuously concentrated impelling from a plurality of angles to wire rod with bullet, its wire rod is subjected to the strike and the friction of powerful intensive bullet all over the body, oxide skin on it, rusty scale and dirt thereof come off rapidly, obtain smooth finish surface;
Described bullet is a ∮ 0.3mm cast steel ball, and hardness is HRC45～50;
Described Shot Blasting is friction feeding operation cleaning; Total blast volume is 50m
3/ min, static pressure is 300mmH
2O;
4), take-up: on electricity drives automatic take-up equipment, wire rod shaping equipment plays the effect that the curved surface of the pending wire rod of emitting is organized into the straight line material above the servo-actuated draw drum to the nickel-chromium alloy wire rod after the processing by Pan Yuan.
The contrast of beneficial effect of the present invention and traditional acid wash: it is thorough to have the effect of removing, and removing speed is fast, and the polishing loss is little, does not have waste material substantially and produces the simple advantage of treatment process.
A. removing speed is fast, efficient is high: the shot-blasting machine per minute is eliminated nickel chromium triangle wire rod surface oxide layer length and is reached 70-90 rice; Acid process needed 1-2.5 hour could remove the nickel chromium triangle wire rod surface oxide layer of equal specification length clean.
B. the wire rod loss is little: it is 1um that the ball blast method is removed nichrome surface oxide layer average thickness, per hundred kilograms of wire rod loss in weight≤1%; Acid wash acid etching speed is difficult for accurately grasping, average acid etching thickness 5um, and wire rod loss in weight ≈ 5%, the ball blast method reduces wire rod loss 80% than acid wash.Cleannes: Asa2.5-3.0, surface roughness Ra 12.5.
C. environmental protection: the ball blast method is removed in the alloy wire process and is not used chemicals, does not have problem of environmental pollution; Acid wash will be removed the cost height with various strong acid chemicals preparating acid washing lotions, easily environment is produced in the operating process and pollutes.
Description of drawings
Fig. 1 is a technological process schematic block diagram of the present invention.
Among the figure: 1 servo-actuated draw drum, 2 wire rod trimmers, 3 shot-blast cleaning machines, 4 electricity drive auto take-up, 5 power control systems, 6 nickel-chromium alloy wire rods.
Below in conjunction with the accompanying drawing explanation detailed in addition to embodiments of the invention.
The specific embodiment
Know that from accompanying drawing 1 a kind of method that is used to remove oxide layer on surface of nickel-chromium alloy wire rod of the present invention may further comprise the steps:
