TH25139B - Initial methods for continuous casting - Google Patents

Abstract

DC60 A process conforming to this invention has been characterized that prior to the start of casting, the initial position (31) has been defined for the stopper control actuator. When the bar is stuck The filling is placed on the support platform under the influence of the weight of the fill rod itself and after being filled. The socket, which has already been provided with this stopper. The actuator will be operated to be placed in a controlled and strongly closed position (33) and in order to initiate casting, the actuator will be driven strongly. In accordance with the law of relation of the given motion with time (34), time (t1) for starting the Casting has been established by this rule. And the control actuator continues to be driven in the For opening So that the metal can flow into the bar formwork. They can be applied to the continuous casting of metals especially steel. The process corresponding to this invention has been characterized that prior to the start of casting, the initial position (31) was defined for the stopper control drive. When the bar is stuck The filling is placed on the support platform under the influence of the weight of the fill rod itself and after being filled. The socket, which has already been provided with this stopper. The thrusters are operated to be placed in a controlled and strongly closed position (33), and in order to initiate casting, the thrusters are driven strongly. Comply with the law of relation of the given motion with time (34) time (t1) for starting the Casting has been established by this rule. And the control actuator continues to be driven in the For opening So that the metal can flow into the bar formwork. They can be applied to the continuous casting of metals especially steel.

Claims (6)

1. Initial process for continuous casting in casting installers, including sockets with outlet holes. Which can be blocked by a block Resting on The stopper supports, the mechanical connection path between the stopper and the actuation drives of the stopper and the rod formwork, which accepts the metal flowing through the outlet. Which has the characteristics Before starting casting a) Place the stopper on the support of the stopper, resulting only from the weight of the stopper itself, where the control actuator is in idle state. And in the starting position Which is defined by The position of the stopper b) determine the aforementioned starting position of the control actuator c) then the control throttle drive in the direction for closure. To force the stick to block Is on the support of the stopper Until the propulsion acting on the control actuator reaches the specified value At that time The control actuator is in a very closed position. D) Drive the control actuator to place the control actuator in the controlled closed position. Which is defined by the second set distance of the control actuator position relative to the starting position, where this defined second distance is less than the first and in the start of the casting f) the actuator. Drive the control in the direction for the opening according to the relationship rules between The forced motion of the control actuator and the time at which the start of the casting is determined From this rule, by calculating with this law, the time spent by the control actuator to memorize the completely closed position. G) and continues to drive the control actuator in the direction for opening. So that the metal can flow Into the bar formwork 2. Initial method for continuous casting in casting tools, including sockets with outlet holes. Which can be blocked by a block Resting on The stopper supports, the mechanical connection path between the stopper and actuator, controls the movement of the stopper and the rod formwork, which accepts the metal flowing through the outlet. Which has the characteristics Before starting casting a) Place the stopper on the support of the stopper, resulting only from the weight of the stopper itself, where the control actuator is in idle state. And in the starting position Which is defined by The position of the stopper b) determine the aforementioned starting position of the control actuator c) then the control throttle drive in the direction for closure. To force the stick to stop Is on the support of the stopper Until the control actuator reaches the designated completely closed position, which is determined by a predetermined distance to the initial grip; d) Add liquid metal to the socket The controlled exciter is held in a closed, controlled position. Which is defined by the second set distance of the control actuator position relative to the starting position, where this defined second distance is less than the first set distance, and in the start of the casting f ) Drives the control actuator in the direction for the opening according to the relational rule The forced motion of the control actuator and the time at which the start of the casting is determined From this rule, by calculating with this rule, the time spent by the control actuator to move, remember the completely closed position, Controlled to the starting position. And still drives the control actuator in the direction for the opening so that the metal can flow in Can go in a bar formwork 3. The process according to claim 1, which is unique as follows: During the start of casting and after the control actuator is set to the initial position The opening of the stopper continues. Until the fill position, put it below the fully open position. Which has maintained this filling position during the filling of the bar formwork 4. The process according to claim 3, which is unique as follows: Before the level of the metal in the formwork The bar will reach the predetermined casting level. A level control system is activated, which controls the level as soon as the metal level reaches the specified level. 5. Process according to Clause 2, which are unique as follows: During the start of casting and after the control actuator is set to the initial position The opening of the stopper continues. Until the filler position is lower than the open position for filling Which has maintained this filling position during the filling of the bar formwork 6. Process according to Clause 5, which has unique characteristics as follows: Before the level of the metal in the formwork The rod will reach the specified specified casting level. A level control system is activated, which controls the level as soon as the level of the metal reaches the specified level.
