Material for Roll-In Furnace Cart
Material for Roll-In Furnace Cart
(OP)
I am in the process of installing a used, walk-in tempering furnace, and I need to design/build a new, roll-in cart for this furnace. The furnace will be operated at 800 F temperature, but it is rated for 1200 F. The current furnace cart is in rough shape, and it is not strong enough to handle the 10,000 Lbs. max load I need to put on it. Current cart is approx. 4' wide by 6' long, with four cast iron casters.
I know that Stainless is fairly common in the construction of furnace carts and components, but is it necessary to use Stainless when temperatures will not exceed 1200 F. ?
I would like to use economical materials (A36,4130, etc), but I need something that can handle the 10K Lb. load at 1200 F. High temperature creep and strength are critical.
What are some ideas for construction materials.
Thanks,

You could use 4130, but it might work out better to use a hot work (H) tool steel.
Thought, if the weight of the cart isn't a big concern, could you use cast parts to build it? There are case CrMoV grades that would take cycling to these temps all day.

Castiron casters are the chepest and if downtime for replacement is not a concern,continue with it.
