Description

 We have complete manufacturing line and test equipment for spring steel wire product. The annual productive capacity is over 50 thousand MT. We mainly manufacture suspension spring steel wire, valve springsteel wire, clutch spring steel wire, oil pump nozzle spring steel wire and general mechanical spring steel wire. Our products has passed ISO9001,ISO14001,GB/T 28001 certificate and TS16949.

Production methods

Different types of spring steel wire have different production methods, common characteristics are the need for certain strength, high toughness and good coil spring performance.

The processing methods of commonly used spring steel wire are as follows:

(steel) rod -- surface treatment -- wire drawing (mattress steel wire can be used by this method)

Lead hardened spring steel wire: lead bath quenching is carried out in the coil size or the middle specification of cold drawing, and then surface treatment and wire drawing are carried out.

Galvanized spring steel wire: it is usually hot-plated or electroplated in the finished size, or cold-drawn to the specified size after hot-plated by strip pickling.

Oil quenching spring wire: according to the need can use carbon steel or alloy steel, surface treatment and cold drawing to the finished size after quenching tempering treatment, the technology on automobile suspension spring and valve spring wire use morer, ordinary spring, of course, also can be used.

Spring steel wire:

In Spring steel wire after proper heat treatment or cold drawing hardening, high strength and hardness, high elastic limit and fatigue limit (especially the notch fatigue limit), cutting performance, but the weldability and cold plastic deformation ability is poor.

Due to the high carbon content, cracks are easy to occur when water is quenched, so two-fluid quenching (water quenching + oil cooling) is often adopted, and oil quenching is often used for small-section parts. Such steel is generally used after quenching by tempering or normalizing at medium temperature or surface quenching. Mainly used for manufacturing springs and wear - resistant parts. Carbon tool steel wire is a kind of steel that does not contain alloying elements, and it is also a kind of steel with low cost, good cold and heat processing and wide range of use. Spring steel wire includes high carbon steel wire, one of the spring steel wire. Anything that can make a spring can be called a spring wire, and high carbon means high carbon content.

Features: high strength and hardness, high elastic limit and fatigue limit (especially notch fatigue limit). My company has 60 sets of wire drawing equipment, production of tensile strength from 1270 mpa to 1670 mpa, wire diameter 1.2 mm - 5.0 mm Φ Φ, reverse number in more than 20 times, repeated bending should be more than 15, Spring steel wire.View of the surface state, good formability, high plasticity, uniform size, high dimensional accuracy, brightness is good, corrosion resistance, acid and alkali resistant, high temperature resistant, not easy to wear, not easy ageing, high tensile strength and fatigue resistance, chemical stability, steel purity, low inclusion content etc.

Sinosteel Zhengzhou Research Institute of Steel Wire Products Co., LTD began to build in 1973 and was restructured in 1999 to be scientific and technological enterprise, a wholly-owned subsidiary of Sinosteel Corporation, mainly engaging in research and development of new technique, new technology, new material, new equipment and new product of steel wire and steel wire products. we have more than 400 junior and senior engineers.



In recent years, the institute, resting on the particular qualified personnel and technical superiority has increasingly upgraded the scale so that its product covers various spring steel wires, welding wires, profile wires, cold heading wires, stainless steel wires and wire ropes, production equipment of welding wire, production equipment of wire drawing and industrial automation control systems.

 

The national “863” project, oil quenching-tempering spring steel wire for high stress valve spring, has been industrialized, and the oil-tempered spring steel wire for suspension spring has won the title of National Key and New Product, the products covering such fields as aero-space, railway, machinery, auto, metallurgy and building. Moving to Zhengzhou High-tech Industries Development Zone in September, 2006, the institute has been stepping up to reallocate resources with great efforts and highlight the comprehensive advantages, striving to build up a development and industry base of new material of high-end metal products in the country soon.     

 

We have complete manufacturing line and test equipment for spring steel wire product. The annual productive capacity is over 50 thousand MT. We mainly manufacture suspension spring steel wire, valve springsteel wire, clutch spring steel wire, oil pump nozzle spring steel wire and general mechanical spring steel wire. Our products has passed ISO9001,ISO14001,GB/T 28001 certificate and TS16949.Sinosteel group is more and more welcomed by domestic and foreign businessmen and enterprises! In the future market strategy, we will as always, together with the vast number of customers to create more brilliant tomorrow!
