Product Description

Water-Cooled Tubular Compensator

Product Overview 

Water-cooled tubular compensator (metallurgical electric furnace dedicated water-cooled expansion joint integrating conductivity and cooling) serves as the core integrated conductive & cooling fitting for the short net system of submerged arc furnaces, electric arc furnaces and refining furnaces. It is installed between the secondary outlet copper tube of furnace transformers and the front-furnace conductive copper tubes of the short net, combining four major functions: high-current conduction, circulating water cooling, multi-dimensional displacement compensation and vibration damping.
Adopting a double-layer tubular sandwich water cooling structure, its conductive body is made of high-purity copper. Circulating cooling water continuously dissipates Joule heat generated by heavy current and radiant high temperature from the furnace. Meanwhile, it absorbs axial displacement caused by thermal expansion and contraction, assembly errors from on-site installation, and alternating electromagnetic vibration during smelting. This prevents stress cracking, water leakage and conductive burnout of short net copper tubes and transformer copper bars, ensuring 24-hour continuous stable operation of smelting systems. It is an indispensable safety matching component for high-load metallurgical electric furnace short nets.

Structural Composition

  1. Inner Conductive Tube (Main Conductive Layer)

    Seamless T2 high-purity copper tube with high conductivity and low resistance, bearing the ultra-large operating current on the secondary side of electric furnaces and directly contacting cooling medium. Integrally forged flanges or taper sleeve conductive joints are formed at both ends with silver-plated contact surfaces to cut contact resistance and reduce ablation from heat generation.
  2. Water-Cooled Sandwich Cavity

    A sealed water circulation interlayer formed by fully welded inner and outer tubes, equipped with water inlet and outlet nozzles. Cooling water circulates all around the conductive copper tube without cooling dead zones, rapidly removing conductive heat and radiant high temperature from furnaces.
  3. Sliding Expansion & Compensation Mechanism

    Precision-fit telescopic section of the inner tube allows free axial expansion and contraction, matched with a guiding limit anti-drop structure to avoid water leakage caused by tearing under ultimate tension; it supports compensation of minor radial and angular offset.
  4. Insulating Protective Outer Layer

    High-strength high-temperature resistant fiberglass insulating sheath, isolating short circuits of external metal components, insulating heat and preventing scalding to lower on-site risks of burns.
  5. Fastening & Sealing Assemblies

    Heat-resistant rubber gaskets and high-strength stainless steel bolts achieve multi-layer sealing on flange surfaces, with no leakage under long-term high-temperature vibration working conditions. An elongation observation mark is attached to visually check the telescopic compensation status.

Key Performance Indicators

  1. Contact Resistance: ≤0.03μΩ (lower for silver-plated joints to reduce heat loss)
  2. Cooling Efficiency: Single unit heat dissipation capacity 15~120kW per hour, eliminating overheating and red-hot copper bodies
  3. Vibration Resistance: Withstand alternating electromagnetic vibration during smelting without loose joints or water leakage in continuous operation
  4. Service Life: ≥5 years under normal soft water working conditions, extendable to over 8 years with regular maintenance

Core Product Advantages (Promotional Selling Points)

1. Integrated Conduction & Water Cooling for Energy Saving

Full coverage double-layer sandwich water cooling eliminates local high-temperature dead zones, greatly lowering temperature rise of the entire short net system and reducing reactive power loss of transformers and copper bars. Compared with ordinary bare copper flexible connectors, it cuts power consumption by 8%~15% and avoids shutdown failures caused by burnout of conductive parts.

2. Multi-Dimensional Displacement Compensation to Eliminate Equipment Stress

Solves three major working condition challenges simultaneously:

① Axial expansion and contraction induced by high-temperature thermal expansion and cold contraction;

② Assembly deviations from equipment installation and civil engineering foundations;

③ Sustained vibration generated by alternating electromagnetic force during smelting.

It protects welds of transformers and conductive copper tubes from stress damage and sharply cuts maintenance frequency.

3. High Conductivity & Low Loss, Suitable for Ultra-Large Current

Integrally formed seamless T2 copper with sufficient conductive cross-section. Silver-plated surfaces on flanges at both ends deliver ultra-low contact resistance, with controllable temperature rise under heavy current. It matches submerged arc furnaces for ferrosilicon, silicomanganese, ferrovanadium, yellow phosphorus and calcium carbide as well as steelmaking electric arc furnaces under high-load conditions.

4. Reliable Sealing for Long-Term Leak-Free Operation

Full welding process for sandwich cavities plus composite multi-layer flange sealing resists alternating cold and heat and continuous vibration, eliminating hidden risks of seepage and dripping water. A limit anti-tension structure prevents cavity tearing under maximum telescopic travel, avoiding production shutdowns due to water leakage during continuous smelting.

5. Compact Structure, Easy Installation & Maintenance

Integral tubular design occupies minimal space, adapting to narrow front-furnace short net layouts. No external water cooling hoses are required; electric and water circuits can be connected synchronously on site, with disassembly and assembly completed simply by removing flange bolts. Worn sealing parts can be replaced separately instead of the whole compensator, cutting operation and maintenance costs significantly.

6. Full-Condition Customization for All Types of Metallurgical Furnaces

Customizable cross-section, length, compensation stroke, water inlet/outlet layout and flange dimensions to match furnaces ranging from small refining furnaces to large-scale 10,000 kVA submerged arc furnaces. Complete sets of short net accessories including water-cooled cables, conductive cross arms and taphole openers can be supplied together.

Applicable Industries & Matching Equipment

  1. Ferrous Alloy Smelting: Short net systems of submerged arc furnaces for ferrosilicon, silicomanganese, ferrochrome, ferrovanadium and ferronickel
  2. Calcium Carbide & Yellow Phosphorus: Secondary conductive connections of large closed submerged arc furnaces
  3. Steelmaking: Short net conductive cooling of AC/DC electric arc furnaces and LF ladle refining furnaces
  4. Non-Ferrous Smelting: High-current conductive systems of copper, aluminum, lead-zinc smelting furnaces and reduction furnaces
  5. Matching Accessories: Electric furnace transformers, water-cooled conductive copper tubes, water-cooled cables, conductive cross arms and complete short net fittings

Product Selection Guidelines

  1. Core selection parameters: Rated secondary current of furnace transformer, outer diameter of short net copper tube, reserved on-site installation length, required telescopic compensation stroke, cooling water supply pressure
  2. For heavy-duty working conditions (current>25000A), select upgraded models with silver-plated flanges and enlarged water-cooled interlayers to reduce heat generation
  3. For areas adjacent to high-temperature furnace bodies, choose models with thickened high-temperature resistant fiberglass insulating sheaths
  4. For factories with high water hardness, a soft water circulation system is recommended to extend the service life of internal water channels of the compensator
