Jun 10, 2014· Having molten lead or gold poured down your throat, they conclude, is a pretty sure way to die: it might rupture your organs, burn your lungs and choke you. Ultimately, though, it's probably the ...
As the metal begins to melt, the electrodes may be pushed farther into the mix or pulled apart to create a larger arc. Heat and oxygen might be added to speed the process. As molten metal starts to form, the voltage can be turned up, as the slag created on top of the metal acts like a protective blanket for the roof and other components of the EAF.
Pewter Casting Molten Metal Thermometer for less then 1000F. With a 200-1000 F. temperature range, stainless steel construction, large numbers printed on a 1-1/2" covered face, and +/- 1 accuracy, this lead thermometer lets you pour lead at the optimum temperature. This is the same as the RCBS thermometer - the same manufacturer -though we ...
If using lead, I highly recommend soft lead compared to the "hard-alloy based" lead used in wheel weights. It is a good idea to mention or request soft lead from your local scrap yard, generally they will be more than willing to accommodate you. When melting any soft metal, be sure to perform the melting and pouring with adequate air ...
The resulting oxides are almost always insoluble in the molten alloy, so they tend to separate and form a separate phase. In the case of bullet casting alloys, tin is more readily oxidized than is lead, so the tin oxide forms a "skin" across the surface of the melt.
Sep 09, 2014· I don't honestly know how hot your tools get when working with the molten lead. I have seen videos of guys using regular welding gloves to pour and work with the molds, weights, and jigs. What concerns me is that when you're working with the lead you'll inevitably accumulate lead dust, shavings, and splash on your gloves.
To resist corrosion by molten lead at 550 ºC, you can select crucibles of MgO, Al 2 O 3, MgAl 2 O 4, ZrO 2, fused quartz or fused silica, or graphite. Cite. 1 Recommendation.
Mar 13, 2011· The discoloration on the top is nothing but impurites and the resulting oxidation with the air. If you are bottom pouring, leave this layer of discoloration/top slag alone, ladle to the side when adding more lead. If you are top ladling, just use your ladle to move it to one side of the pot, scoop your lead and pour.
Nov 07, 2007· Ok, Just received my first two Do-It molds from Stamina. Fired up the Coleman camping stove and put the cast iron pot on it full of lead. About 45 minutes the lead was melted, but when I pour it into the mold the hole got clogged up with lead and I didn't get a full pour.
"Lead Area". Good hygiene and ventilation are the best way to 48824 PREVENTING LEAD POISONING WHILE CASTING Know lead properties: Lead melts at 621°F. Fumes are released at 900°F. Lead can be breathed in and also settle on surfaces. Lead oxide (fumes mixed with air) forms a fine yellowish/brown dust. Even with
The reported pools of molten metal under the rubble must also have contained some of that molten steel, and perhaps molten iron from thermitic cutting charges as well. Figure 7. An excavator picks up metal rubble from deep within the pile, and some of it is dripping a yellow-white hot liquid metal at or above 1200°C/2200°F.
Oct 29, 2019· Dear CBO's Please comment about the following statement I found on internet: "The ideal temperature for casting wheel-weight alloy bullets should be only slightly higher than the melting point of lead (621° F). However, to get good filling out of the mold most casters run about 625° to 675° F." 1) What's your advice to someone who doesn't want to reinvent the wheel?
Jul 03, 2008· It certainly should help your pouring go smoother, as long as you're doing everything else right. I used to pour a lot of salmon balls in 1.5, 2, and 2.5lb sizes. By removing the lead oxides on the surface, and making the melt less likely to form oxides, fluxing will help make sure the metal is as fluid as possible, so pours go easier.
Oct 31, 2019· Lead temperature does affect this, and how hot the mold gets, but adding an intermediate heat source makes possible casting with lead as cool as 600 degrees (as cool as what doesn't freeze in the nozzle in your bottom pour). With a mold heater, lead this cool can be made to cast shiny (even wrinkled) boolits - to boolits that are severely ...
Jun 11, 2021· The production pot holds the lead about 6 inches above the work surface and has a spout at the bottom and when you open the valve the spout allows molten lead to pour out into your mold. When I set myself up to cast some lead bullets, I will generally …
Dec 15, 2007· The best thing I have found to ladle it out with is an old metal (with metal handle) soup ladle. ... and a piece of expanded metal on that. Pour WWs onto the expanded metal, melt with a weed burner and catch the molten lead in a pot (bend the sheet steel to form a trough). The clips stay up on the expanded metal.
Nov 01, 2017· For molten metal splash hazards, clothing may be rated for levels of protection according to ISO 9185 (D1, D2, or D3 for aluminum; E1, E2 or E3 for ferrous metals. Wear pants or leggings that cover the top of the boot (and spats, if worn) to prevent molten metal and sparks from entering the boot. Never tuck pant legs inside the boot or spats.
allowing lead to pour back. (8) Screening the remaining trash from the molten lead. (9) Pouring lead into forms. (10) Finished lead ingot. (11) Lead pipe often has a fair amount of antimony mixed into the lead. The antimony will need more heat to melt and it will cool form a ring at the top of the pot.
Aug 13, 2012· Even then, the blocks just sat in the molten lead. After half an hour, without even melting the edges, I gave up and melted them into the pot with the torch. The block type solder was the same. Didn't want to melt, so I just did it with the torch. The lead roof flashing sheet melted into the liquid lead …

Re: Proper Temp For Pouring Lead. Author: PLUMBILL. The best way to check the proper temp for lead is to tear off the corner of an old newspaper page, dip it in the lead and pull it right out. If the newspaper edge is burning, chared, or blackened the lead is to darn hot, the papers edge should be lightly browned (tinge) and then the temp is ...

Be careful not to interpret the downvote on Blacksmith37's answer as meaning that it is safe to pour into a damp mold. A mold must be fully dry before pouring in molten metal, or the water vapor caused by the molten metal hitting the damp mold will blow the metal back out, and possibly also blow the mold apart.
May 08, 2021· Another great source of lead are the old school tire balance weights or range lead. Pick up the larger spent projectiles, wash them off and dry them extremely thoroughly. Any trapped water between a bullet jacket and the lead core might cause a catastrophic lead explosion. All of the molten lead will be ejected out of the furnace at high speed.
