Definitions
- the invention relates to a method for the continuous casting of blocks, billets, Slabs, especially thin slabs, in the size range of about 20 up to 150 mm thick and about 600 mm to 3500 mm wide, by means of an oscillatable, water-cooled mold in cooperation with a diving spout underneath Use of casting powder to form casting slag.
- the invention also relates a device for performing the method.
- DE 198 10 672 A1 describes a method for measuring and regulating Temperature and amount of water-coolable per unit time, especially from each other Independent mold walls made of cooling water flowing through copper plates a continuous casting mold.
- the invention is that the cooling water temperature a mold wall in at least two places in the area of the drain openings a copper plate and the associated water tank is measured and a temperature profile from the values measured across the width of the copper plate is created and temperature profiles obtained in time intervals with each other be compared.
- the inlet temperature of the cooling water is measured the difference between the inlet and outlet temperature is determined and from the Amount of cooling water per unit of time the partial integral heat dissipation from one Mold wall or determined from a mold belt area and partial inequalities compensate by making partial corrections to the cooling water.
- the liquid-cooled mold for performing the method is designed so that in the water drainage area between a copper plate and the cooling water drain opening of the water tank, in particular at least per broad side plate Two points are arranged temperature sensors and their signal lines to one Computer, preferably connected to an online screen.
- the object of the invention based on a method and a device for the continuous casting of blocks, Billets, slabs, especially thin slabs, specify which are suitable are local temperatures and / or heat flux densities along the altitude of mold walls and in several places along their broad sides and from this the temperature load in contact with the melt located mold wall preferably in the meniscus area.
- Means The measured values should include operating parameters such as the amount of cooling water and the casting speed and mold powder are controlled so that at a preferred working temperature the mold walls in the meniscus area an optimal surface formation the slabs with the longest possible availability of the mold becomes.
- thermocouples are each arranged at different depths (X 1 , X 2 ) of the mold wall, and that from the temperature difference at least two in approximately the same height range (Yi, e.g. y 1 , y 2 ) local thermocouples the associated local heat flow density is calculated.
- an embodiment of the method according to the invention provides that by determining the temperature or heat flow curve over the height of a The mold wall uses approximation functions to determine the maximum temperature profile the wall area in contact with the melt is calculated.
- a further embodiment of the method provides that when a Heat flow density change in the mold height (y) due to two-dimensional Heat spread in the area of the bathroom mirror (M) by assuming a heat flow density curve on a mold surface and with knowledge of the heat flow density in the depth (x) of a mold wall the position of the bath level (M) is determined online.
- a detection device provided for carrying out the method of local temperatures and / or heat flow densities on a water-cooled Mold in the continuous casting of blocks, billets, slabs, in particular of thin slabs, according to the invention is that in the broad side walls the mold in an area above and below the bathroom mirror as well as in each approximately equal distances from their contact surface with the molten metal Thermocouples are inserted in pairs, via signal lines are connected to a computing unit, which according to the determined Temperature or heat flow density is the surface temperature of the mold calculated in the meniscus area and which to control a preferred one Working temperature of the mold wall within a given temperature range ( ⁇ T) the operating parameters of cooling water quantity, pouring speed and Mold powder adjusts ..
- FIG. 1 shows a temperature profile or a heat flow curve over the height (y) of a mold wall and in at least two spacing areas (x 1 , x 2 ) of the mold wall from the molten bath (M).
- the course of the strongly drawn curve (y 1 , y 3 , Y 5 , Y 7 , Y 9 , Y 11 ) shows a pronounced temperature maximum (T max ) in the range of a predetermined temperature range ( ⁇ T).
- the measuring points located further inside the mold wall (y 2 , y 4 , y 6 , y 8, y 10 , y 12 ) show a similar curve with a maximum temperature (T max ) in the meniscus area (M).
- the temperature profile of the mold surface is calculated from the measured temperature profiles.
- the temperature curves can be measured in an electronic measuring device Display can be recorded online and made visible. You can use it for this the temperature in the specified temperature window ( ⁇ T) to keep the automatic control of the decisive operating parameters constant, to achieve an optimal surface formation, for example with a thin slab.
