Having determined what is required we now proceed to inquire into the question of carburizing, which is of vital importance. ❋ Unknown (1916)
* Briefly describe alternative carburizing agents (wood, charcoal, animal bone, leather, etc.) and mention other methods of case hardening. ❋ Unknown (1982)
The selection of suitable boxes for carburizing is worthy of a little consideration, and there can be no doubt that in certain cases results are spoiled and considerable expense caused by using unsuitable containers. ❋ Unknown (1916)
Output 3,000 lb. charge, 8 hr. heat carburizing, 2 hr. heating only. ❋ Unknown (1916)
For successful carburizing, the following points should be carefully observed: ❋ Unknown (1916)
In fact, this is a good scheme to use for the majority of carburizing work of small and moderate size. ❋ Unknown (1916)
Case hardening boxes cast iron local or surface carburizing treatments for various steels ❋ Unknown (1916)
As this compound comes from the carburizing pots it contains bits of fireclay which represent a part of the luting used for sealing, and there may be small parts of work or bits of fused material in it as well. ❋ Unknown (1916)
One of the advantages of hardening by carburizing is the fact that you can arrange to leave part of the work soft and thus retain the toughness and strength of the original material. ❋ Unknown (1916)
The carburization then goes on for several hours before the furnace is cooled below the effective carburizing range, securing an ideal diffusion of carbon between the case and the core of the steel being carburized. ❋ Unknown (1916)
The old way of case-hardening was to dump the contents of the box at the end of the carburizing heat. ❋ Unknown (1916)
After marking, all holes and parts which are to remain uncarburized are plugged or luted with a mixture of kaolin and Mellville gravel clay, and the gear is packed in the carburizing material. ❋ Unknown (1916)
Water inlet and outlet pipes are shown and also a drain plug that enables the tank to be emptied when it is desired to clean out the spent carburizing material from the bottom. ❋ Unknown (1916)
The heat treatment used to obtain the above physical properties consisted in carburizing at a temperature not to exceed 1,675°F., for a sufficient length of time to secure a case of from 0.02 to ❋ Unknown (1916)
The addition of a slight amount of powdered cyanide of potassium to the packing material used for carburizing will produce stronger colors, and where this is the sole object, it is best to maintain the box at a dull-red heat. ❋ Unknown (1916)
Although the advantages offered by the gas-fired furnace for carburizing have been generally recognized in the past from points of view as close temperature regulation, decreased attendance, and greater convenience, very little information has been published regarding the consumption of gas for this process. ❋ Unknown (1916)
It is common practice to leave a sieve or wire basket to catch the work, allowing the carburizing material to fall to the bottom of the tank where it can be recovered later and used again as a part of a new mixture. ❋ Unknown (1916)
The utmost care should be used in the selection of pots for carburizing; they should be as free as possible from both scaling and warping. ❋ Unknown (1916)
In the simpler carburized steels it is not necessary to test the forgings for hardness after annealing, but with the high percentages of alloys in the carburizing steels and the heat-treated steels ❋ Unknown (1916)
Effect of alloys of different carburizing material of size of piece of copper in medium carbon steel ❋ Unknown (1916)
Dude I'm definitely a [master] [carburator], I do it [every day] at lunch. ❋ TheLion12 (2011)
