Molten Metal Safety Boots for Foundry and Steel Mill Applications.

Molten Metal Safety Boots Application Scenarios: 

1. Steel Mill (Steel Plant): Typical positions include Steel Melting Worker, Furnace Operator, Casting Worker, Ladle Worker, Continuous Casting Worker. 

The main risks they face include splashing molten steel, high-temperature slag, red-hot billets, high-temperature floors, and steel falling.

2. Foundry (Foundry Factory), including Iron foundry, Steel foundry, and Aluminum foundry.

For instance, in the casting of automotive parts, engine cylinder blocks, cast iron components, and metal molds, there are risks such as molten iron pouring, aluminum liquid splashing, and the generation of casting residues.

What should a pair of qualified Molten Metal Safety Boots possess?

The core logic is to prevent molten metal from entering the shoes, the shoe surface from catching fire, the metal from adhering to the shoe surface, the heat from transferring to the feet, heavy objects from injuring the feet, and steel slag from puncturing the shoe bottom, etc.

I. Shoe Upper Material Requirements: 

We recommend Full Grain Leather (full-grain cowhide).

Because it cannot be used in a molten metal environment. Mesh, ordinary fabrics, and ordinary PU cannot be used. Once molten metal drips, it will burn through, melt, and adhere.

The best configuration is Waterproof Heat Resistant Leather.

Features: Thick cowhide, flame-retardant treatment, heat-resistant, fire-resistant.

The upper part of the shoes requires a Smooth Upper Design.

Molten metal is most afraid of gaps, grooves, and laces holes. once the molten metal enters, it will remain and burn.

Therefore, an integrated upper, with fewer stitching lines and a concealed structure, is recommended.

The recommended height for the shoe shaft is Mid-Calf / High Cut Boots, which can prevent molten metal from entering through the trouser legs.

The boot opening should fit the leg snugly and be easy to remove quickly.

II. Shoe Toe Cap Material : 

Steel Toe or Composite Toe are both acceptable , just ensure it meets the 200J impact protection standard.

III. Midsole Material : 

Kevlar Anti-Puncture Midsole .

IV. Shoe Outsole Material :

A HRO Heat Resistant Rubber Outsole is required to provide protection against contact with hot surfaces; at the same time, SRC Slip Resistance is also needed. the recommended insulation material for heat insulation is HI Heat Insulation, which helps to reduce the transfer of heat from the ground.

The best combination: outsole heat-resistant rubber + middle layer insulation layer + insole heat-resistant cushioning layer.

Recommended certification combination: EN ISO 20349-1 + EN ISO 20345, with base S3 or S7 (waterproof requirements) plus:

Fe (Molten Iron), Al (Molten Aluminium), HRO, HI, P, SRC.
