FIELD: process engineering. ^ SUBSTANCE: invention relates to continuous casting of steel strip at two-roll casting machine. Proposed doorframe 25 has opposed outer surfaces. One said surface stays in contacts with molten metal while opposite outer side has connecting parts 320, 330 and 340 to fasten doorframe to holder 37. Said holder 35 of lateral doorframe 35 has no parts extending beyond boundaries of opposite outer surface 310 in direction of outer surface 311 in contact with molten metal. Holder 37 is provided with appropriate fasteners for positioning of lateral doorframe. ^ EFFECT: longer service life. ^ 26 cl, 5 dwg |
