Scrap It or List It?

Unsure about whether to scrap or try and sell a surplus furnace? We have this guide to tell you what to scrap and what to list (disclaimer time; these are general guidelines only and a lot will depend upon age, condition and time frame for having the equipment removed). So keeping that in mind we have this list of 10 different styles of furnaces starting with the least desirable and ascending to the most valuable and most desirable type of furnace;

12) Fluidized Bed Furnaces-Cut it up! This is really a no brainer.

11) Shaker Hearth Furnaces-off to the trash bin you go. Granted once in a blue moon you run across an operating shaker hearth but so seldom that it generally is not worthwhile trying to find a buyer.

10) Older endothermic generators. It is a mystery to us why new generators are selling fairly well but old generators you can’t give away. An older generator without updated cooling or controls-call the scrap guy. Older generators with updated cooling and controls, give it 6 months before you call the scrap dealer. Multi retort generators-list it.

9) Rotary Retort Furnaces. These have a very mixed history on the used market. Generally, we would consider them to be worth more as scrap but they generally seem to find a buyer-flip a coin before you cut it up.

8) Rotary Hearth Furnaces. Our opinion is that these are 50/50 between finding a home or being scrapped. So, let’s say if it is in good shape list it, poor shape and it’s out of here.

7) Mesh belt lines. When first introduced to North America the standard as set by Can Eng was 1,000 pounds per hour, over the years this had inched up to 4,000 to 6,000 pound/hour units. The older style 800-1,000 pound/hour furnaces we would suggest looking for a garbage bin, anything over 3-4,000 pounds/hour list.

6) Cast link belt lines. Now this is a tricky one because, so few are ever installed in a given year. New these are expensive and if you find a buyer with a need they are a valuable item, however sitting on a large cast link belt line can be an expensive proposition. Our suggestion would be to list a good condition cast link belt line, one in marginal or poor condition or on the small side-cut her up.

5) Pusher lines. Same as above a good condition pusher line is a prized item for a buyer with a definite need, however these virtually never sell in a hurry.

4) Batch Integral Quench furnaces. As the most common style of furnace in the world there are some very good guidelines for scrapping or listing. Small units such as a 24” X 36” or smaller-trash it. 30” X 48” or larger list it and the larger the furnace the more demand there is.

3) Nitriding furnaces-list them all! Gas nitriding, plasma nitriding everybody is looking although we have one word of caution. Some of the older Plasma nitriders are famous for their rather funky power supplies and if there are issues with the power supply the system is basically worthless.

2) Vacuum carburizing systems. Always worth listing for the simple reason that so few ever come on the market. As an example, a large ALD system was auctioned off by Caterpillar last year-the system attracted multiple very good offers before being sold.

1) And the most in demand type of used furnace? Vacuums! A good condition vacuum with reasonable working dimensions and 2 bar or higher quenching will sell in a matter of hours sight unseen if the price is reasonable and quite often even if it is not reasonable.

Cut Them Up!
