Steel Plant HS High-Sulfur Alloy Slide Plate Self-Lubricating High-Temperature Resistant

Introduction to HS Self-Lubricating, High-Temperature Resistant Alloy

New Technology Introduction Based on fully exploiting the characteristics of HS high-sulfur alloy steel, our company produces HS alloy bearings, angular contact joint bearings, sliding bearings, slide plates, sliders, guard plates, and many other products. These are widely used in large and medium-sized steel enterprises across the country and have been well received and highly praised. In metallurgy, applications include sinter plant cooler bushings, converter trunnion bearings, straightening machine bearings, secondary cooling section bushings, conveyor roller bearings, shear machine sliders, nuts, and heating furnace conveyor rollers. Bearings made from this material require no lubricating oil or water cooling and have a service life 3-5 times that of ordinary bearings and bushings. In coal mines, ports, chemical industry, agricultural machinery, and other fields, HS alloy steel also shows promising development prospects. The application of HS high-sulfur alloy steel reduces equipment investment and cumbersome maintenance work, while also contributing to energy saving, consumption reduction, and efficiency improvement.

Wide range of applications, covering many fields.

Plate mill, hot rolling mill, cold rolling mill, wire rod mill, large rolling mill, medium rolling mill, coking plant, ironmaking plant, power plant, mining, transportation machinery.

Physical and Mechanical Properties, Advantages, and Applications of HS Alloy

Physical and Mechanical Properties of HS Alloy

(1) Linear expansion coefficient: a=8.96x10-6/°C

(2) Friction coefficient: f=0.1 (initial) ~0.05 (after operation)

(3) Allowable speed: [v]=6m/s

(4) Allowable specific pressure: [p]=30-45 MPa

(5) Allowable (pv) value: [pv]≥25-30 MPa·m/s

(6) Hardness: HB=140~560 (after heat treatment)

Advantages of HS Alloy

(1) High load capacity: Bearings made of HS alloy have no cage or rolling elements, resulting in high load capacity, which is improved compared to ordinary rolling bearings.

(2) Excellent self-lubricating and anti-seizure properties: HS alloy contains various alloy compounds and 0.5~11% free sulfur. When rotation (sliding) friction begins, the friction surface quickly releases multiple solid lubricants that fill the micro-pits on both surfaces, forming a stable solid lubricating film that provides lubrication and prevents seizure.

(3) Outstanding high-temperature resistance: HS alloy can reliably operate at temperatures up to 800°C without lubrication or cooling. If used in medium to low-temperature environments, its service life is even longer.

(4) Low friction coefficient: Multiple tests and applications have shown that the initial friction coefficient of HS alloy is similar to that of ordinary steel due to the delayed release of self-lubricating substances. However, as rotation (sliding) continues, various solid metal lubricants are released, forming a lubricating film, and the friction coefficient gradually decreases. F=0.1~0.05

(5) High operating linear speed: HS alloy bearings can operate smoothly and reliably at v<6m/s, especially performing better at low speeds.

Applications of HS Alloy

Due to its unique properties, HS alloy is suitable for various high and low-temperature environments. It is particularly ideal for harsh conditions such as oil-free, water-free, high-temperature, high-dust, and debris-prone environments.

It can replace various imported and domestic bearings.

It can replace various powder metallurgy bearings and self-lubricating bearings.

It can replace various heavy-duty, low-speed rolling bearings.

It can replace various joint bearings.

It can replace slide plates, sliders, liners, bushings, and sleeves made of various materials.

Using HS alloy for bearings, slide plates, sliders, etc., can eliminate traditional dry or liquid lubrication and cooling systems, thereby reducing equipment investment and cumbersome maintenance work. It also contributes to energy saving, consumption reduction, and pollution prevention.

To facilitate design units in querying relevant technical parameters and users in selecting products, we have compiled a product catalog for HS alloy bearings, bushings, slide plates, sliders, etc. We can also design and manufacture non-standard products of various structures based on user requirements.
