Abstract
The invention discloses a steel wire pickling process, which comprises the following steps: firstly, coiling a wire rod; secondly, primarily stretching the wire; thirdly, carrying out heat treatment; fourthly, preheating and heating the pickling tank; fifthly, conveying the wire rods for acid cleaning, controlling the temperature of hydrochloric acid, and continuously keeping the temperature at 40 ℃; sixthly, carrying out phosphorization and saponification after the acid washing is finished; and seventhly, stretching the finished product. According to the steel wire pickling process provided by the invention, on the premise that the surface quality is guaranteed, the production cleaning efficiency can be improved, the output of dangerous waste is reduced, the use efficiency of hydrochloric acid is improved, and the waste rate is reduced.
Description
Technical Field
The invention relates to a steel wire pickling process.
Technical Field
The traditional process is that when the wire is subjected to acid cleaning after heat treatment, hydrochloric acid or sulfuric acid and the like are used, because the sulfuric acid is used for cleaning, heating is needed, the temperature is kept high, the sulfuric acid is strong in corrosivity and high in risk coefficient, hydrochloric acid is mostly adopted for cleaning in the traditional wire cleaning industry, the hydrochloric acid is volatile and has weaker corrosivity than sulfuric acid, the waste period is short and the like, the wire is basically in a normal temperature state in use, the temperature is not controlled, but the requirements of customers on the surface quality of the wire, environmental protection and hazardous waste and the like are higher and higher, the key point of research is how to improve the use efficiency of the hydrochloric acid and reduce the waste amount, and therefore under the condition that the specific gravity and the like with the same concentration are not changed, the temperature is adjusted for control, the cleaning efficiency of the acid.
Disclosure of Invention
The invention aims to provide a steel wire pickling process, which improves the service efficiency and service time of hydrochloric acid by controlling the service temperature of pickling hydrochloric acid and adopting different temperatures under different working conditions.
In order to solve the problems, the acid pickling process for the steel wire rod provided by the invention adopts the following technical scheme:
a steel wire pickling process comprises the following steps:
firstly, coiling a wire rod;
secondly, primarily stretching the wire;
thirdly, carrying out heat treatment;
fourthly, preheating and heating the pickling tank;
fifthly, conveying the wire rods for acid cleaning, controlling the temperature of hydrochloric acid, and continuously keeping the temperature at 40 ℃;
sixthly, carrying out phosphorization and saponification after the acid washing is finished;
and seventhly, stretching the finished product.
Furthermore, in the fourth step, a Teflon heating tube bank is adopted for heating, and steam is used for reducing the heat of the hydrochloric acid.
Further, in the fifth step, real-time monitoring is performed by using a temperature sensor, and the hydrochloric acid temperature is kept at 40 ℃.
The invention has the beneficial effects that: according to the steel wire pickling process provided by the invention, on the premise that the surface quality is guaranteed, the production cleaning efficiency can be improved, the output of dangerous waste is reduced, the use efficiency of hydrochloric acid is improved, and the waste rate is reduced.
Detailed Description
In order to more clearly understand the technical solutions provided by the present invention, the present invention is further described below with reference to specific embodiments.
The invention provides a steel wire pickling process, which comprises the following steps:
firstly, coiling a wire rod;
secondly, primarily stretching the wire;
thirdly, carrying out heat treatment;
fourthly, preheating and heating the pickling tank;
fifthly, conveying the wire rods for acid cleaning, controlling the temperature of hydrochloric acid, and continuously keeping the temperature at 40 ℃;
sixthly, carrying out phosphorization and saponification after the acid washing is finished;
and seventhly, stretching the finished product.
Furthermore, in the fourth step, a Teflon heating tube bank is adopted for heating, and steam is used for reducing the heat of the hydrochloric acid.
Further, in the fifth step, real-time monitoring is performed by using a temperature sensor, and the hydrochloric acid temperature is kept at 40 ℃.
When hydrochloric acid is heated to 40 ℃ plus or minus 2, the original cleaning time can be reduced by about 10 percent under the condition that the concentration, specific gravity, iron ions and the like are not changed, the original waste period can be maintained at the constant temperature of 40 ℃ plus or minus 2 under the same condition, and the waste period can be delayed by about 20 percent.
The present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make various modifications without creative efforts from the above-described conception, and fall within the scope of the present invention.
