How far apart should forge burners be?

Forge Design: The burners are typically spaced six inches apart so that one burner's flame's 8-inch diameter will overlap the adjacent one by a couple of inches as shown in Figure 3.

What PSI Do you run a forge at?

The burners can run efficiently across a pressure range of 3- 20 PSI.

How big should a single burner forge be?

The basic rule of thumb when building or buying a single burner forge is to make sure your forge adheres to the 250-300 cubic inch of space per 3/4 inch burner rule.

Does a forge need to be open on both ends?

Yes, blocking one side of a propane forge will help concentrate the heat in the forge and on the work.

How do I make my forge hotter?

Forge Burners Explained!

How long does a forge take to heat up?

“After the forge gets hot and you are running on repetition, it will keep its top temperature at 8 lbs. At this pressure, it should take you 3 to 3-1/2 minutes to get up to forging temperature on the first heat.”

Why propane flames are orange?

Orange or yellow propane gas flames give you a warning that your propane gas is not being completely burned. When these color flames occur on the burners of a propane cooktop, the cause is usually related to a burner being out of adjustment or blockages in the air inlet, such as from small, burnt food particles.

What color should propane flames be?

With complete combustion, LPG (Propane) burns with a blue flame. Pure hydrocarbons like methane (refined natural gas), propane, butane and ethane gases also burn with a blue flame. These gases are all alkanes and are gas that burns with a blue flame.

How much time does it take to forge a knife?

This depends on the type of knife and how experienced you are with the ways of making a knife. The forging can take anywhere from 1-4 hours for smaller knives. Then it will take 2-3 hours to harden and temper, depending on how many times you choose to temper your knife.

How many Btus is a gas forge?

Model: Gas Propane Forge DFSW with 1 Burner DFP (80.000 BTU) is powerful and high quality. It is specially designed for blacksmiths, farriers, and knife makers. The compact construction makes the forge portable and easy to take to any place you need.

What is forge welding temperature?

Pure iron can be welded when nearly white hot; between 2,500 °F (1,400 °C) and 2,700 °F (1,500 °C). Steel with a carbon content of 2.0% can be welded when orangish-yellow, between 1,700 °F (900 °C) and 2,000 °F (1,100 °C).

How hot can a propane forge get?

The combustion temperature of propane is 1,967 degrees F for combustion with air and 2,526 degrees for combustion with pure oxygen (The Engineering ToolBox). Typical forge welding temperatures for a propane forge are accepted as 2,300 degrees F, and common forging can be accomplished at a lower temperature.

Why does my gas forge sputter?

If it's a blow out type sputtering, then you're not getting enough air, if it isn't that I'd probably say it was LPG entering the burner and causing it to flare.

Why is my propane flame green?

Improper air / gas mixture.

How do you get a blue flame on a propane stove?

You get a blue gas flame with a hydrocarbon gas when you have enough oxygen for complete combustion. When you do have sufficient oxygen, the gas flame appears blue because complete combustion creates enough energy to excite and ionize the gas molecules in the flame.

How hot should a forge be?

a. Hot forging of steel: The forging temperatures are above the recrystallization temperature, and are typically between 950°C–1250°C. Usually, one experiences good formability (i.e., filling of die-cavity in the context of forging), low forming forces, and an almost uniform tensile strength of the work-piece.

How hot does a coke forge get?

Heating The Metal

The result is coke, a fuel that is almost entirely carbon allowing us to reach temperature of 3,000 to 4,000 degrees Fahrenheit at the core of the fire! Fire this hot can quickly get the metal up to welding temperatures at about 2,500 degrees.

How hot is it on forged in fire?

Meanwhile, the forges and other heating equipment used by the smiths are capable of running well above one thousand degrees Fahrenheit, according to a tour video uploaded on YouTube by the History Channel. This, combined with all of the lighting equipment, makes the set an extremely hot place.

How long does it take steel to heat in a forge?

Both the ASM Metals Handbook and ASM's Forming and Forging Handbook state that "for stock up to 3 in. in diameter, the heating time per inch of section thickness should be no more than 5 minutes for low-carbon and mediumcarbon steels, or more than 6 minutes for low-alloy steels.
