Last week we mentioned how quench salt supplier Park Thermal had abruptly closed their doors leaving many heat treaters with salt quenching requirements scrambling to find another source. Hubbard Hall, a long established supplier of salts has “stepped up to the plate” and can handle all of your salt needs. Their banner ad can be found on the right hand side of this page https://www.hubbardhall.com/ap

Today Carlos Torres of “The Heat Treat Podcast” speaks with Mr. Raman Bawa, General Manager of Metex Heat Treating. The main topic is “Heat Treating of Fasteners” as Metex is one of the largest in North American for continuous heat treating. Raman talks about the history of the company, what is involved in processing fasteners and where Metex is going.

Super Systems, Inc. recently completed a controls upgrade for Elmira Heat Treat in Elmira, NY. The scope of the project included a new 9220 control system for a vacuum furnace. The 9220 is a robust vacuum furnace recipe based controller which is the command center for control, I/O, and redundant data logging for the processes performed on the equipment. The instrument was integrated into their existing plant-wide SuperDATA SCADA package for plant wide visibility, historical load tracking and recipe selection based on shop order part numbers.
Elmira Heat Treating is the premier thermal processing provider in western New York, offering Carburizing, Hardening, Nitriding, and Vacuum services. Founded in 1962, their 80,000 square foot plant serves a wide variety of customers in various industries. Elmira’s team has over 100 years of combined experience in offering quality products and services to the heat treat market. For more information about Elmira Heat Treat, visit www.elmiraht.com.

Earlier this week we posted the question below about whether anybody in the industry could offer onsite calibration of Mass Flow Controllers. One reader responded saying that he had almost 200 MFC units in his facilities and that when he sent them out for calibration it would typically involve a cost of about $200-$400.00 USD each, so yes he was very curious about whether such a service exists. Alas after a lot of digging and numerous comments it does not appear that anybody in North America can offer an onsite service-damn.
“Onsite Mass Flow Controller Calibration; One of the largest captive heat treaters in North America posed to us a very interesting question, one for which we do not have a good answer; “We are looking for a source to perform onsite mass flow controller calibration to NIST requirements. To date we have not found anybody which can offer this service-does “The Monty” have any good suggestions”. We reached out to a couple of US companies offering calibration and TUS surveys and each said basically the same thing that they do not get enough requests for this service to make it worthwhile. An instrumentation company we approached suggested that they would to this in house but NOT onsite and said that typically the manufacturers of mass flow controllers would offer this service but not in the field. So the question is-are there any companies out there that could perform this service? [email protected]

It would appear that there might be a crisis in the making for the supply of quench salts-lets provide some background. For years now a very substantial player in the supply of quench salts in North America has been Park Thermal International in Georgetown, Ontario, Canada. Park has supplied the industry with Neutral Salts for austentizing, hardening, annealing, normalizing and pre-heating. High Speed Steel Hardening Salts for solution treating, quenching, tempering and casting. Quenching & Tempering Salts for low temperature drawing, quenching and ausquenching/austempering and martempering and Salt Bath Rectifiers to help maintain optimum bath operating conditions. As reported in “The Monty Heat Treat News” just last week the company very unexpectedly closed their doors for good without giving their customers any warning. So far “The Monty” has fielded a half dozen calls just this morning all asking the same thing-who else supplies quench salts? We are going to do some digging and provide some alternatives. Stay tuned.

This photo shows Park Thermal quench salts in use at a captive heat treater in the USA who has a number of mesh belt austempering furnaces in operation.
From furnace builder BMI of France we have this news item about the company receiving orders for 2 vacuum tempering furnaces from two different customers, one in Spain and one in Italy; “We have just signed the pre-acceptance protocol for two new tempering furnaces type B55R, one of which is also capable of a low pressure nitriding process. Each furnace can handle a load of up to 2000kg. One furnace will be shipped to a commercial heat treater in Spain, who already has two BMI furnaces installed (aluminum brazing and gas quenching furnaces). The second furnace will be shipped to Italy, to a tool making manufacturer for in-house heat treatment of their own production. These new orders are proof that despite the COVID crisis, the industry sector in Europe is flourishing. Our customers increase their production capacity in order to meet the market needs and that is great news for Europe’s economy.”

COVID related issues have effected the entire worldwide supply chain meaning that lead times for everything has increased. Furnaces, alloy components, combustion burners and quenchant have been adversely effected. Just today we were approached by a very large heat treater desperate to find a supply of UCONN A NN quenchant for their Induction heat treat department. We approached the supplier Chemtool who said they like everybody else have had supply chain issues beyond their control and yes deliveries were slower. If there is anybody out there with several barrels of UCONN A NN Quenchant this heat treater would be very interested in knowing about it. [email protected]

Up in Connecticut, USA we see that Southwick & Meister Inc., a manufacturer of collets, bushings and cutting tools have ordered another small box furnace. The furnace comes from Lucifer Furnaces and will be used to heat treat under a nitrogen atmosphere. The 9-inch-high x 12-inch-wide x 18-inch-long chamber is lined with 5 inches of a combination of lightweight firebrick hot face backed with cold-face mineral wool for energy-efficient operation and low outside shell temperature. The furnace is fabricated from 10-gauge sheet steel reinforced with structural-steel members continuously welded to form a solid shell for operation with a positive flow of inert atmosphere.
