Unique TwistLink® dragline chain makes every bucket count.
PORTLAND, OR - JULY 2008 - Dragline operators sometimes need to watch their weight -- rigging weight, that is.
When Columbia Steel was looking for a way to improve the design of conventional dragline chain, "it was all about the weight," says product engineer Steve Doan. "We wanted a design that would reduce weight and still maintain flexibility and strength."
Why reduce weight? "When removing overburden, you want to make every bucket count," explains Tony Miotke, Columbia Product Engineering Manager. "Weight reduction translates into increased production, because lower rigging weight allows for more payload per bucket."
TwistLink chain has demonstrated excellent reliability in both hoist and drag applications. The unique double-pitch design can reduce chain weight up to 18% when compared to conventional chain. Its increased surface area in the bite region of each link and increased cross-sectional strength improves wearability. TwistLink's notable resistance to abrasion and ability to handle impact are the results of Columbia's H-series alloy, which combines high tensile strength and toughness.
Columbia Steel is headquartered in Portland, Oregon. The 86-acre facility is home to an on-site product design and engineering department and full-service steel casting foundry. They will be exhibiting at Booth 6075 in MINExpo's Central Hall in Las Vegas, Nevada, from September 22 to 24, 2008.

Xtralloy® proves its worth to crusher operators for two decades.
PORTLAND, OR - JULY 2008 - This year marks the 20th year anniversary for Xtralloy, a unique high carbon and manganese alloy from Columbia Steel that changed the way the aggregate and mining industries think about wear part life in tough, abrasive applications.
Although high carbon and manganese steel from Europe began making inroads in the States in the early 1980s, it wasn't until 1986 that high performance crusher wear parts significantly hit the market, when metallurgists at Columbia Steel developed a way to produce thick, heavy sections of the new alloy.
That process included an extensive field review of crusher operations throughout the U.S. in the early 80s by Columbia Product Engineer Chuck Hendrickson. "I visited 55 customers in 17 states in 21 days," recalls Hendrickson about the whirlwind tour. What he saw convinced Chief Metallurgist Phil Belding back at the Portland, Oregon, foundry that they were on to something.
"Heavy section cone liners were a casting type which had been universally avoided by all of the other premium manganese steel producers in this country," says Belding. By experimenting with both ingredients and processes -- specifically heat treating - Belding and the Columbia Steel foundry found a solution to these problematic thick castings.
What was the first product made from the new Xtralloy alloy? "We started by manufacturing 7-foot Symons cone parts," says Chuck Hendrickson. "Nowadays we produce a large volume of different cones and jaws, as well as gyratory concave segments, and even rolls for shredders."

Replacement wear product numbers pose the question:
"Are you using the right parts?"
PORTLAND, OR - JANUARY 2008 - In preparation for ConExpo-Con/Agg 2008, Columbia Steel Casting Co. recently audited its jaw and cone patterns for wear parts, all manufactured at its U.S. foundry, and the numbers may come as a surprise in an industry in which outsourcing is increasing.
Columbia Steel offers over 1,900 replacement jaw designs engineered to fit over 380 jaw crusher models. Among these, the PIONEER® 30x40 represents the model for which Columbia manufactures the greatest number of jaw wear parts, accounting for 52 jaw designs and 136 matched pairs for customers' specific crushing needs.
"In calculating these latest numbers, alloy choices and duplicates that can be used on different crushers were not included, leaving only unique designs to be counted," explains Alan George, Communications Manager, adding, "As part of the criteria for the cone crushers counted, only those with bowl liners were considered."
Those cone designs added up to over 1,100 available for over 120 cone crusher models. One popular example is the NORDBERG® 4-ft. short head cone crusher, for which Columbia offers 51 replacement cone designs. For this model alone, 74 matched cone pairs have been made available to Columbia customers.
According to Product Engineering Manager Chuck Hendrickson, the record number of designs is a direct result of developing wear parts in response to customer requests to resolve specific crushing situations. "When applied properly, some designs -- like concave and convex profiles -- significantly affect jaw crusher performance. Even minor differences in physical appearance can improve operating performance: for example, shortening the discharge point on a movable jaw to allow a better stationary and movable match-point on closer than normal run discharge settings. For the customer this can mean improved wear life of up to 25 percent -- sometimes more."
"We get more positive results with the proper or improved geometry being used in the wear part than from alloy selection. The material specification is secondary in 7 out of 10 situations. This is true assuming the material is as good as it can be and is properly applied, in terms of wear-ability and fatigue resistance," Hendrickson adds.
Columbia Steel is headquartered in Portland, Oregon. The 86-acre facility is home to an on-site product design and engineering department and full-service steel casting foundry. They will be exhibiting in the ConExpo-Con/Agg Central Hall at Booth 6535.
