I.Project Background

In the steel smelting industry,the blast furnace ignition system is a critical piece of equipment during furnace startup.To ensure a safe and reliable ignition process,modern steel mills widely adopt telescopic ignition devices.These devices must continuously extend and retract during operation,necessitating the simultaneous carriage of multiple lines,such as:

Ignition control cables

High-pressure gas hoses

Control signal lines

Towing steel cables

These lines require synchronized retraction and deployment management during equipment operation.Without a reliable retraction system,issues like cable entanglement and hose damage frequently occur.

Managing multiple lines within steel mill blast furnace equipment has long been an engineering challenge.

Common problems include:

Limited line space

High number of lines

Long line travel distances

Harsh operating environments

Many devices experience:

①Severe cable abrasion(Repeated motion during prolonged operation causes cable deterioration.)
②High-pressure hose kinking damage(Hoses without dedicated reeling systems suffer excessive bending.)
③Difficult pipeline maintenance(Equipment shutdowns are frequently required to address pipeline issues.)

These problems not only reduce operational efficiency but also increase maintenance costs.

Therefore,the client seeks to resolve these issues through an integrated hose and cable reel system.

II.Core Technical Requirements

Based on the actual operating conditions of blast furnace ignition systems,the customer specified the following technical needs:

1️⃣Synchronized Retraction/Deployment of Four Lines
The system must manage:
1 steel wire rope
1 control cable
2 high-pressure hoses
Ensuring no tangling or slippage during operation.

2️⃣Compact Equipment Structure
With limited installation space,the system must feature a compact structure for easy mounting.

3️⃣Continuous Power and Gas Supply
As the reels require continuous rotation,the system must ensure:

Continuous power supply capability for cables

Continuous gas supply capability for high-pressure hoses

4️⃣Safe and Reliable Limit Protection
The equipment must incorporate a reliable travel control system to prevent over-travel operation.

III.Solution

To address these requirements,KLD Engineering designed a multifunctional integrated hose and cable reel system.

This equipment features a dual-reel design.

Large Reel
The large reel accommodates two high-pressure hoses and incorporates Pneumatic rotary joints on both sides.This ensures continuous gas supply during reel rotation.

Small Reel
The small reel comprises two independent zones:

Wire Rope Retrieval Zone

Cable Retrieval Zone
The cable zone incorporates an industrial-grade slip ring system to maintain stable power supply during drum rotation.

Synchronous Drive Structure
The system employs:Single Motor Drive+Chain Transmission System
The motor drives both drums simultaneously via a chain.Through varying diameter designs,it achieves:Synchronized retrieval of four lines
This solution offers a simple,reliable structure with easy maintenance.
