Colmonoy® Alloy News – Food & Glass Container

With CISA deeming food and agriculture a critical industry, did you know that Wall Colmonoy has a long history in both food & glass container industries?

Read about how to “get your plow shares ready for spring” and repairs on glass cast iron moulds via a low-heat welding method developed by Wall Colmonoy from our 1956 second issue of Colmonoy® Alloy News.

Agriculture Industry - Plow Share Blades

Get Your Plow Shares Ready for Spring!

In this February 1965 Issue of Colmonoy® Alloy News, Plow share blades are hardfaced with Colmonoy® Sweat-On Paste and Wallex™ alloys.

Coated shares can plow 1400-1600 acres of farmland versus 50 acres for uncoated.  Apply to blades before a share even touches the field to prevent maintenance.

WEAR PROOFING a plow share involves three simple steps. Colmonoy® Sweat-On Paste is applied with a brush to entire length of blade on bottom side ( above left). After being allowed to air dry, Sweat-On Paste is fused to parent metal with oxyacetylene torch flame (above). Illustration at left shows area on top face of plow share point to which 1.59mm (1/16 in.) layer of Wallex™ rod has been applied using oxy-acetylene torch.

MOLDBOARD bottom blades protected with Wall Colmonoy hard-facing alloys. Upper share has plowed in excess of 1400 acres at Wood River, Nebraska; edge is still sharp and in. good enough condition for plowing an additional estimated 1000 acres. Lower blade was hard-faced when new has plowed more than 1600 acres-is still in excellent condition. These useful life figures compare with a normal useful life of 30 to 60 acres for an unprotected share in the Wood River area soil.

Wallex™ is chosen to protect the top face of the plow share:

  1. Cost savings
  2. Offers excellent abrasion and impact resistance
  3. Has extreme low coefficient of friction which sharply reduces wear and enables the share to easily pass through the soil

Wallex™ extends useful life of earth moving and rough material handling equipment as well as gages, grinders, rigs, conveyor parts and pump impellers.

Wallex™ being applied to top / ace of plow share as part of abrasion resistance protection. This low cost iron-base alloy is also recommended for use in wear-proofing earth-moving and rough material handling machinery and equipment.

Today, Wallex™ is now rebranded for cobalt-based alloys and has applications within Agriculture or Food Industry for Knives (Hay Chopper), Collars (Expeller), Runners (Corn Planter) and Spike Harrow Teeth.

Glass Container Industry – Cast Iron Repair

Colmonoy® 20 rod repairs cast iron glass container following manufacture via a low-heat welding method developed by Wall Colmonoy®.

The 3-step method consists of grinding the area to produce a good welding surface; heating to just 93°C (200°F) and applying flux; and finally, welding with Colmonoy® No. 20 nickel-base alloy rod using a reducing oxy-acetylene torch flame.

Minimum heat used with this method keeps the mould from reaching the hardening temperature, preventing formation of hard spots adjacent to the weld. Colmonoy® 20 will not – discolor or mark the finished glass. Alloy hardness is 15 to 20 Rockwell C-can be smoothed by filing.

REPAIRING a cast iron glass-bottle mould by the Colmonoy® low-heat welding method using an oxy-acetylene flame and a 4.76mm (3/16 in.) diameter Colmonoy® 20 rod.

Today’s method of cast iron repair is by Fuseweld™ process and alloy of choice are:

  • Colmonoy® 323
  • Colmonoy® 21
  • Colmonoy® 24
  • Colmonoy® 23A
  • Colmonoy® 225
  • Colmonoy® 226
