Smelting & Heat-Treatment Solution

Hazards encountered by workers during mechanical maintenance or operation lacerations and abrasions

• Examples include feeding unpacking raw material drums moving steel drums disassembling and assembling pipe valves filtration and mixing Drum openings flanges and metal edges easily cut through gloves Once torn chemicals come into direct contact with skin Conventional chemical resistant gloves are soft with poor wear performance and no cut resistance and tear easily upon scraping Cut resistant gloves offer no chemical resistance creating conflicting performance requirements

Burns caused by high temperature and molten metal splashes the primary hazard

• Smelting molten steel molten aluminium molten copper splashes high temperature steel billets furnace walls and flues with extremely hot surfaces
• Heat treatment heating furnaces bogie hearth furnaces mesh belt furnaces radiant heat exposure to hands during workpiece discharge and quenching transfer
• Pain points conventional rubber or nitrile gloves melt upon contact with high temperature sticking to skin and leading to secondary deep burns Ordinary heat insulating gloves cannot withstand molten metal splashes and splashes burn through the glove material

Sharp metal burrs flash and casting edges resulting in cuts and punctures

• Castings forgings and cut steel components have sharp edges Deburring grinding and rough part handling readily cut gloves Many heat resistant gloves provide good thermal protection but no cut resistance standard HPPE cut resistant gloves cannot withstand high temperatures
• Pain points single function gloves fail to meet multiple requirements combined high temperature and cut resistance demands composite materials gloves wear out rapidly requiring frequent replacement
• Oil contamination quenching fluids coolants and mild chemical agent corrosion

Extremely high temperatures on furnace bodies fixtures and freshly discharged workpieces far infrared radiant heat scorches hands Conventional rubber and standard HPPE melt directly under high temperature sticking to skin and causing deep thermal burns

• Pain points ordinary cowhide only resists minor sparks with weak protection against prolonged radiant heat thin aramid cannot sustain continuous high temperature exposure short cuffs leave wrists vulnerable to burns

Quenching oil water based quenchant and salt baths nitrates alkaline solutions hot oil or hot chemicals splash when workpieces are immersed into baths Oil permeates leather making it hard and brittle

• Pain points leather degrades quickly after oil absorption oil splashes bring both thermal burns and chemical irritation
