Dummy Bar Bolts are heavy-duty industrial fasteners engineered for use in steel rolling mills and bar production lines, where they guide and anchor steel billets during hot rolling and continuous casting. These bolts are manufactured from alloy steel or high-tensile carbon steel, as specified in the source, to endure repeated thermal cycling and mechanical stress from high-speed metal flow. The exact material composition is not quantified in the listing, but the designation aligns with industry standards for components exposed to temperatures exceeding 800°C.
Typical dummy bar bolts feature a cylindrical shaft with threaded ends and a flanged or hexagonal head for secure mounting. Standard diameters range from 40 mm to 100 mm, with lengths between 600 mm and 1,800 mm depending on mill configuration. Surface finish is usually machined to a tolerance of ±0.1 mm, and heat treatment to achieve hardness in the 28 - 34 HRC range is common in this application. These are not general-purpose fasteners; they are mission-critical components in continuous production lines where failure causes costly downtime.
These bolts are primarily sourced by steel mill maintenance departments, OEM equipment suppliers, and industrial repair contractors in Asia, the Middle East, and Eastern Europe. Buyers typically require batch deliveries for replacement cycles tied to mill shutdowns. Packaging is usually in wooden crates or steel pallets, with individual bolts wrapped to prevent surface damage. Trade terms are typically FOB Port of Mumbai or Kandla, with lead times of 4 - 8 weeks depending on order volume and material grade availability.
| Material | Alloy Steel / High-Tensile Carbon Steel |
| Typical Diameter Range | 40 mm to 100 mm (standard for rolling mill applications) |
| Typical Length Range | 600 mm to 1,800 mm (based on mill roll stand spacing) |
| Surface Tolerance | ±0.1 mm (typical for precision mounting in high-vibration environments) |
| Hardness Range | 28 - 34 HRC (standard for thermal and impact resistance in steel processing) |
| Head Type | Hexagonal or flanged (common for secure anchoring in fixed mounts) |
| Typical Finish | Machined, uncoated (to avoid contamination of hot steel surfaces) |
| Typical Application Temperature | Up to 900°C (standard operational range in continuous casting lines) |
| Packaging | Wooden crates or steel pallets (typical for heavy industrial components) |
| Compliance Standard | Typically meets ASTM A29 or DIN 1.7225 for high-tensile steel fasteners |
Siphon Refractories Pvt. Ltd. is based in Hyderabad, Telangana, India, with its registered office at Dsr Shell Plaza, Miyapur. The company’s profile indicates active engagement in industrial component supply, with a focus on refractory and metallurgical hardware. The listing shows no verified certifications, no published production capacity, and no disclosed client list. Response metrics are unavailable, and there is no public record of years in operation or export history.
The company is not listed as a manufacturer of dummy bar bolts in public industry directories, and the product appears to be sourced or assembled rather than forged in-house. There is no mention of in-house testing facilities, metallurgical lab access, or third-party quality audits. Buyers should treat this as a trading entity with local sourcing capability, not a certified producer. Verification of material certificates and dimensional compliance is essential before placing orders.
Dummy Bar Bolts are heavy-duty industrial fasteners designed for use in steel rolling mills and bar production lines, where they guide and anchor steel bars during the rolling process. Typically manufactured from alloy steel or high-tensile carbon steel to withstand extreme pressure and thermal stress, these bolts are essential components in continuous casting and hot rolling operations. Available in various sizes and grades, dummy bar bolts are traded internationally for steel mill maintenance, upgrades, and OEM replacement needs, making them a key fastener category in the global industrial supply chain.

Before ordering, verify the material certification (MTR) for alloy steel or high-tensile carbon steel, confirming carbon, manganese, and chromium content within ASTM A29 or DIN 1.7225 limits. Check that hardness values fall between 28 - 34 HRC and request test reports for each batch. Confirm the supplier’s ability to provide dimensional drawings with ±0.1 mm tolerance, as misalignment in rolling mills can cause production stoppages. Do not accept verbal assurances - only written documentation is reliable.
Lead time is typically 4 - 8 weeks, depending on material availability and order volume. Incoterms are usually FOB Mumbai or Kandla; confirm whether loading, export clearance, and documentation are included. Payment terms are commonly 30% advance with 70% against BL copy. Always clarify if packaging meets IS 11751 standards for heavy industrial shipments. Request tracking for containerized shipments and confirm insurance coverage for high-value components.
On arrival, inspect bolts for surface cracks, scaling, or deformation using a magnifying lens. Measure at least three samples per batch for diameter and length against the MTR. Perform a simple hardness test with a portable Rockwell device if possible. Request a certificate of conformity and ensure the MTR matches the batch number on the packaging. Retain samples for 90 days in case of field failure claims. Document all inspections with photos and signatures.
