摘要:
In the context of a method for producing heavy plate (4) from a steel alloy, comprising continuous casting of a steel melt and primary forming of an obtained casting strand to give a slab with subsequent shaping or hot rolling of the slab from the casting heat in multiple shaping steps to a desired heavy plate dimension and an immediately subsequent heat treatment of the heavy plate (4), effecting targeted cooling of the obtained heavy plate (4), wherein the heavy plate (4) is cut to a desired individual plate length before or after its heat treatment as seen in the production direction (3), there is to be provided a solution for producing heavy plate which permits the flexible production of different heavy plate qualities. This is achieved by carrying out the heat treatment in the temperature range of 150°C-1100°C as a combination of targeted cooling of the obtained heavy plate (4) from the rolling heat to a desired first temperature with immediately subsequent targeted heating of the heavy plate (4) to a desired second temperature and immediately subsequent cooling of the heavy plate (4) to a desired third temperature.

摘要:
The invention relates to a method and device for producing hot-rolled products in a combined continuous casting and rolling system (1). The aim of the invention is to provide a reliable method and a compact combined continuous casting and rolling system (1), by means of which the entire length of a device for separating and removing (6) and the investment and operating costs of the combined continuous casting and rolling system (6) can be reduced. The problem is solved by performing the following method steps in the device for separating and removing (6) in order to overcome a disruption in production in a part of the system located downstream of the device for separating and removing (6): (a) separating the endlessly produced precursor material (3) into a strand portion (21) by means of a shears (9); (b) clamping the strand portion (21) by means of a clamping device (23); (c) raising the foot part of the strand portion (21) from the roller table (4) by means of a raising device (11), whereby the foot of the strand portion (21) is drawn away from the shears (9) in the direction of transport (7); (d) cutting the precursor material (3) passing through the shears (9) into a precursor material portion (10) by means of the shears (9); (e) removing the precursor material portion (10) from the roller table (4) by means of a removing device (8), and removing the strand portion (21) until the combined continuous casting and rolling system (1) is ready to operate again.

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Aufbereiten von Walzgut (5,16,22) aus Stahl vor dem Warmwalzen. Aufgabe der Erfindung ist es, ein energieeffizientes Verfahren und eine kompakte Vorrichtung zur Aufbereitung von Walzgut zu finden, mit denen das Walzgut auch bei transienten, rasch wechselnden Geschwindigkeiten zuverlässig erwärmt und dennoch gründlich entzundert wird. Diese Aufgabe wird durch ein Verfahren mit den Schritten gelöst: - Vorwärmen des Walzguts (5,16,22) in einem ersten Induktionsofen (6), sodass das vorgewärmte Walzgut mit einer Oberflächentemperatur T 1 ≥ 1000 °C in eine nachfolgende Entzunderungseinrichtung (7) eintritt; anschließend - Entzundern des vorgewärmten Walzguts mittels mehrerer Wasserstrahlen in der Entzunderungseinrichtung (7); unmittelbar anschließend - Erwärmen des entzunderten Walzguts in einem zweiten Induktionsofen (8), wobei das entzunderte Walzgut mit einer Temperatur T 2 ≥ T Curie des Walzguts in den zweiten Induktionsofen (8) eintritt und die Erwärmung im zweiten Induktionsofen entweder in einer weitgehend inerten oder weitgehend reduzierenden Schutzgasatmosphäre erfolgt; unmittelbar anschließend - Warmwalzen des erwärmten Walzguts in einem Walzwerk (9), wobei das erwärmte Walzgut mit einer Temperatur 1220 °C ≥ T 3 ≥ 1050 °C in das Walzwerk (9) eintritt.

Plant for the continuous casting of thick slabs, blooms or other similar steel products comprising an ingot mould and a series of containment and guiding rollers placed in the area below the ingot mould on both sides of the cast product, i.e. on the intrados and extrados, respectively. The rollers are arranged on at least three longitudinal rows and all have an axial length shorter that the width of the cast product. The rollers of a central longitudinal row are advantageously staggered with respect to the lateral longitudinal row rollers in such a way as to reduce the surface of the bulges created due to the ferrostatic pressure existing in the liquid core of the product at ingot mould outlet. Furthermore, the pitch between the adjacent rollers is advantageously always of different values so as to not cause the buckling of the bulges with a single frequency.

An ultra-low carbon steel slab having a carbon content of about 0.01 mass percent or less is produced by casting at a casting speed of more than about 2.0 m/min using a mold provided with a casting space having a short side length D of about 150 to about 240 mm and an immersion nozzle provided with discharge spouts each having a lateral width d, the ratio D/d being in the range of from about 1.5 to about 3.0. Accordingly, a ultra-low carbon steel slab can be obtained having superior surface quality without performing slab conditioning such as scarfing.
