Abstract
The invention relates to a pickling-free production method capable of phosphorizing a steel strand on line and belongs to the field of a production method of the steel strands. The production method comprises the following steps of: firstly, mechanically removing scale on line: removing the scale from the surface of a wire rod by a combined method of bending and drawing the wire rod through the first drawbench power by using a bending machine according to different hardness and extensibility between the scale and base ferrum, and removing dusts from the surface of the wire rod by using a dust removal device; then phosphorizing on line: inserting the wire rod subjected to scale removal in a phosphorizing slot in which phosphorizing liquid is filled, wherein during online phosphorization, an electrolytic phosphorizing method is adopted; the total acidity of the phosphorizing liquid is controlled to be between 60 and 75 percent and the free acidity is controlled to be between 7 and 11 percent; performing drawing and stranding on the phosphorized wire rod sequentially, producing the steel strand, packaging and delivering. By the method, energy consumption is reduced, staff arrangement is reduced, the labor productivity is increased, pollution is reduced and the environment is protected.
Description
Technical field
The present invention relates to a kind of field of production of steel strand, a kind of specifically steel strand do not have the production method of pickling, online phosphatization.
Background technology
We know that traditional steel strand production and processing method is: raw material earlier through the phosphatization of overpickling scale removal → then, carries out wire drawing → plying production steel strand → packing again and dispatches from the factory.But in the steel strand production process, because its line footpath is thick, carbon content is too high (the 82B wire rod carbon content of producing the steel strand use is between 79-84), fragility is bigger, the pickling free drawing difficulty is very big, and nobody sets foot in always.So, present international, domestic still adopt first pickling, phosphatization, the traditional technology method production of drawing processing then again.The characteristics of traditional pickling drawing technique are, need the employee that operating experience and chemical experiment operating device are preferably arranged, need bigger place, consume a large amount of heat energy (acid cleaning process needs steam heating), water and pharmaceutical chemicals, acid gas, spent acid, waste water have to a certain degree pollution to environment, need more environmental protection input, production cost is higher.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome above-mentioned the deficiencies in the prior art; the production method that provides a kind of steel strand not have pickling, online phosphatization had both been saved energy consumption, had been reduced personnel's configuration, had improved labour productivity; reduce pollution again, protected environment.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of steel strand do not have the production method of pickling, online phosphatization, it is characterized in that comprising the steps: at first, online mechanical scale removal, utilize oxide skin different with hardness and ductility between the basic iron, utilize the first road drawing wire machine power that wire rod is removed the wire rod surface scale by the bending press bending with drawing the method that combines, remove the wire rod surface dirt by cleaning apparatus again; Enter online phosphatization then, walk in the phosphatization groove through the wire rod of descaling, phosphatization liquid is housed in the phosphatization groove, online phosphatization adopts the electrolytic phosphating method, and General Acidity in Phosphating Solution is controlled between the 60-75%, and free acid is controlled between the 7-11%; Carry out wire drawing, plying production steel strand successively, pack and dispatch from the factory through parkerized wire rod.
The invention has the beneficial effects as follows: both saved energy consumption, reduced personnel's configuration, improved labour productivity, reduced pollution again, protected environment.
Embodiment
The invention will be further described below in conjunction with embodiment:
The present invention includes following step: at first, online mechanical scale removal, utilize oxide skin different with hardness and ductility between the basic iron, utilize the first road drawing wire machine power with the 82B wire rod by the bending press bending with draw the method that combines and remove wire rod surface scale (centre adds calendering straightening better effects if), remove the wire rod surface dirt by cleaning apparatus again, machine barking will suitably be adjusted the bending angle according to the difference of drawing speed and the starting material place of production, line of material footpath, material hardness; In addition, joint (excessive) wants smooth transition, can not force bending excessive; Enter online phosphatization then, walk in the phosphatization groove through the wire rod of descaling, phosphatization liquid is housed in the phosphatization groove, online phosphatization adopts the electrolytic phosphating method, and General Acidity in Phosphating Solution is controlled between the 60-75%, and free acid is controlled between the 7-11%; Carry out wire drawing, plying production steel strand successively, pack and dispatch from the factory through parkerized wire rod.
