CRYSTALLISER Russian patent published in 2011 - IPC B22D11/55 B22D11/04 

FIELD: process engineering.

SUBSTANCE: invention relates to metallurgy, particularly, to continuous metal casting. Crystalliser comprises cartridge 1, cooling jacket 8, body 2 with top and bottom covers 3 and 4 making closed cavity, diaphragm 5 dividing said cavity into pressure and drain chambers 6 and 7, tie rods 9 to lock diaphragm 5. Three spring stainless steel tie rods 9 are arranged in crystalliser pressure chamber 6 between bottom cover 4 and diaphragm 5. Tie rod length-to-diameter ratio makes 40-80. Tie rod thread diameter is defined by formula M=D/(33-60), where D is body ID. Clearance between diaphragm 5 and body 2 makes 0.1-0.7.

EFFECT: stable clearance between crystalliser cartridge and cooling jacket, ruled out cooling water losses.
