Abstract:
A method of measuring and regulating temperature and quantity of cooling water of a continuous casting mold flowing per unit of time through water coolable mold walls composed of copper plates, particularly mold walls which are independent of each other, the method comprising measuring a cooling water temperature of a mold wall at at least two locations in an area of a discharge opening of a mold wall and a corresponding water box, adjusting a flow velocity and a water pressure of the cooling water in an area of water discharge openings of the copper plate, such that a portion of water discharging from the mold at the water discharge openings has a temperature at the boundary of the boiling temperature, and all other portions of water discharging from the mold at higher temperatures undergo bubble evaporation causing subcooled boiling of the cooling water, further comprising adjusting the flow velocity and the cooling water pressure in the cooling ducts so as to be constant, such that an increased thermal load is compensated by a correspondingly increased bubble evaporation.
