Buy a shorter one. Welding Cast Iron is a pain and to do what you want would require cutting out a section and re-welding the whole thing. Baseboard hydraunic heaters can be shortened but cast is a no go.
A steel tub is typically lighter and more affordable than a cast iron tub. Cast iron tubs are heavier and more durable, but also more expensive. Cast iron tubs retain heat better and are known for their classic look, while steel tubs are easier to install and maintain.
I think you need a pump; cast iron is not affected by the heat and cool (the clanging) cycle associated with gravity heat, but the new one might be, especially if it is copper tubing. Didn't they quit making those furnaces like decades ago?
They are iron, so with enough heat, they will melt. Because of the nature of cast iron, they will probably crack and break before they melt.
Cooking on a cast iron griddle offers benefits such as even heat distribution, excellent heat retention, and the ability to create a nice sear on food. Additionally, cast iron is durable, versatile, and can add iron to your diet.
Cooking with cast iron offers benefits such as even heat distribution, durability, and the ability to add iron to your diet.
More than likely due to the heat generated. why are engine blocks maid of cast iron
You can buy the new cast iron flanges, with the expandable O rings that push into the pipe or you'll have to do the old style or pouring lead onto a cast iron flange. The latter option should only be done by professionals.
Cast iron holds heat longer compared to glass, copper, stainless steel.

You will need to give more information. The Btu's of baseboard is determined by the water temperature and the type and size of the element. Copper fin tube (copper pipe with aluminum fins over it) heats up quick and loses heat quickly it also has many diameters of element (copper tube). Most common in residential is 1/2", 3/4" & 1" ID (the OD will be 1/8" or so larger). There is also Cast iron baseboard that heats up slowly and cools off slowly (this is a much more even and comfortable heat). You should never mix and match cast iron radiation and copper radiation of the same circuit it will cause large temperature swings in conditioned area. Tell us what the boiler temperature is set to and what the type of radiation is and you'll get an answer.
