Abstract
The invention discloses a production process of specially-shaped steel wires which have high size accuracy and high product quality. The production process comprises the following steps: producing semi-finished products of circular wires, drawing, annealing, oil quenching, tempering, checking, packaging and warehousing. The production process is characterized in that a low-temperature (350-580 DEG C) stage in the step of annealing is under the protection of nitrogen gas, and a high-temperature (580-840 DEG C) stage is under protection of methyl alcohol; as a further improvement, a steel tube type electric heating muffle furnace is used for heating in the step of oil quenching, the temperature fluctuation of a hearth is +/- 3 DEG C, and the nitrogen gas for protection is added into the steel tube. The production process is suitable for production of the specially-shaped steel wires.
Description
Technical field
The present invention relates to a kind of profile wire, relate in particular to a kind of technique that profile wire is produced that is suitable for.
Background technology
Profile wire is complex-shaped, description is many, China manufacturing enterprise takes drawing, rolling and draw the mode of rolling combination, can produce the profile wire of various shape, material also develops into structural carbon steel from straight carbon steel, carbon spring steel, alloy tool steel, stainless steel, heat-resistant and etching-resistant alloy steel, high chromium bearing steel and non-ferrous metal etc., condition of delivery has as-annealed condition, cold drawn state and oil quenching state, there is into dish delivery, also there is vertical bar delivery, specification is not from 0.4～14mm etc., substantially the needs in market have been met, but in wire shape size, tolerance, still there is certain gap the aspect such as poker and surface treatment with developed countries.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of dimensional precision is high, the profile wire production technique of good product quality.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The present invention includes the operations such as circle silk work in-process, drawing, annealing, oil quenching, tempering, check, packing, warehouse-in; it is characterized in that low-temperature zone in described annealing operation (350～580 ℃) employing adds nitrogen protection, high temperature section (580～840 ℃) adopts and adds methyl alcohol protection.
As preferably, described oil quenching operation adopts steel pipe type Reformation of Electrical Heating Muffle Furnace to heat, and fire box temperature fluctuation is ± 3 ℃, and in steel pipe, adds nitrogen protection.
During due to annealing of the present invention, oil quenching operation, add shielding gas; effectively prevent the generation of Steel Wire Surface decarburization phenomenon; even to guarantee the metallographic structure of the rear poker steel wire of annealing, avoid surface decarburization to produce larger fluctuation to the product size after cold rolling and performance, thereby improve the quality of products.
Accompanying drawing explanation
Fig. 1 is process flow sheet of the present invention.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
The present invention includes the operations such as circle silk work in-process, drawing, annealing, oil quenching, tempering, check, packing, warehouse-in, low-temperature zone in annealing operation (350～580 ℃) adopts and adds nitrogen protection, high temperature section (580～840 ℃) adopts and adds methyl alcohol protection, by methyl alcohol row solution when the high temperature, become carbon monoxide and hydrogen, effectively prevent annealed wire surface decarburization; Oil quenching operation adopts steel pipe type Reformation of Electrical Heating Muffle Furnace to heat, and fire box temperature fluctuation is ± 3 ℃, and in steel pipe, adds nitrogen protection, effectively prevents Steel Wire Surface decarburization.
