Abstract
Abstract Oxygen-free copper ingots are withdrawn from a mold during continuous casting by applying a contact pressure of from 1 to 3 kg/mm2. The contact pressure is applied through surfaces having a smaller modulus of elasticity than the ingots.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
46 words
A method for withdrawing an oxygen-free copper ingot from a mold in the course of the continuous casting of said ingot without introducing residual deformation into said ingot, said method comprising withdrawing the ingot by applying thereto a withdrawal means contact pressure not exceeding 3 kg/mm2.
Claim 2
Independent Claim
46 words
A method for withdrawing an oxygen-free copper ingot from a mold in the course of the continuous casting of said ingot without introducing residual deformation into said ingot, said method comprising withdrawing the ingot by applying thereto a withdrawal means contact pressure not exceeding 3 kg/mm2.
Claim 3
Dependent Claim
16 words
A method as claimed in claim 1 wherein said pressure is applied transversely of said ingot.
Claim 4
Dependent Claim
25 words
A method as claimed in claim 1 wherein said pressure is applied through pressure applying members having a smaller modulus of elasticity than the casting.
