HARDENING OF CASTING FROM THE CORE SIDE AT VERTICAL CONTINUOUS MOULDING
The problem of hardening of fusion in a crystallizer from a core side at vertical continuous molding is solved. It is established that hardening of casting from a core side proceeds in 7–10 time more slowly, than from a crystallizer. Influence of a core on the thermal mode of casting during her hard...

description | The problem of hardening of fusion in a crystallizer from a core side at vertical continuous molding is solved. It is established that hardening of casting from a core side proceeds in 7–10 time more slowly, than from a crystallizer. Influence of a core on the thermal mode of casting during her hardening in a crystallizer during the first 15–20 with slightly, the core didn’t manage to get warm. Settlement thickness of a crust by 20th second of formation has made no more than 1,5 mm. When using thin-walled shell cores thickness of the crust formed on a core has made ξ = 2,0–2,5 mm or less than 10% of casting thickness. Use of continuous cores raises a share of the metal hardening on a core to 15–18%. In this case the coefficient of accumulation of heat a core is accepted equal ξ = 0,75–0,85. |
