摘要： PURPOSE:To control the level of the molten metal in a mold easily by regulating the volume of a freely expandable and contractable hermetic chamber provided between a tundish and the mold and the rate of change in the volume owing to expansion or contraction in a specific range in said chamber. CONSTITUTION:A hermetic chamber consisting of an inside cylinder 3', an outside cylinder 3 and a bellows 7 is provided between a tundish 1 and a mold 2, and the pressure of the inert gas in the hermetic chamber is controlled with control valves 4, 5. The volume V in the hermetic chamber is set in the range of V=(1.0-10.0)A.H (where A is the sectional area of the mold 2, and H is the distance between the top end surface of the mold 2 and the bottom surface of the tundish 1 at the rising limit of the mold 2). The rate DELTAV of change in the volume of the hermetic chamber when the hermetic chamber expands or contracts as a result of the vertical oscillation of the mold 1 is regulated in the range of DELTAV=(0.002-0.005)V. The level of the molten metal in the mold 2 in the stage of starting casting is thus stabilized quickly, whereby the responsibility with the fluctuation in the level of the molten metal in the mold 2 and the change in the control pressure during casting is improved and the control thereof is made easy.
摘要翻译：目的：通过调节设置在中间包和模具之间的可自由膨胀和可收缩的密封室的体积，以及由于膨胀或收缩在特定范围内的体积变化率，可以容易地控制模具中熔融金属的含量在所说的房间里构成：在中间包1和模具2之间设置由内筒3'，外筒3和波纹管7组成的密封室，并且用控制阀4控制密封室中的惰性气体的压力，密封室中的体积V设定在V =（1.0-10.0）AH的范围内（其中A是模具2的截面积，H是模具2的顶端表面与模具2的顶端表面之间的距离中间包1的底面在模具2的上升极限）。当密封室由于模具1的垂直振动而膨胀或收缩时，气密室的体积变化率DELTAV被调节在DELTAV =（0.002-0.005）V的范围内。开始铸造阶段的模具2中的熔融金属的水平因此得到稳定化，从而提高了模具2中的熔融金属的水平波动和铸造时的控制压力的变化的责任，其控制变得容易。

摘要： PURPOSE:To provide an assembled mold for continuous casting which is of compact construction and is improved of a function of depriving molten steel of heat and high temp. strength by forming an electrodeposition layer of an abrasion resistant metal on the inside circumferential surface of a flask-like blank mold formed with flow passages for cooling between an inside facing material and an outside facing material. CONSTITUTION:A mold flask is formed of composite materials made by joining an inside facing material of a steel type material 14 of good heat conductivity and an outside facing material of a ferrous material 15 of high-temp. strength. Cooling water passages 16 are formed between the inside and outside facing materials of the composite materials, and a flask-like blank mold is assembled of these into a box shape. A finishing line is formed on the mating surfaces of the blank mold in its longitudinal direction, and an electrodeposition layer of an abrasion resistant material such as copper nickel, or chromium is formed on the inside surface of the line so that the mating surfaces in the longitudinal direction are buried into the electrodeposition layer. The expansion in the mating surfaces owing to the yield phenomena of the surface material owing to thermal stress during casting is eliminated by this. Since the mold walls can be made thin, the loss of magnetic lines of force during electromagnetic agitation is reduced.

摘要： PURPOSE:To convey many continuously cast steel ingots automatically at a constant period to a heating furnace by gathering said ingots from plural strands on a chute with a transverse feeder, and delivering these to a conveyor communicating with the heating furnace by each piece with a shifter. CONSTITUTION:When the continuously cast steel ingots 2 from plural strands arrive on respective carrying-out tables 1, a transverse feed chain conveyor 3 travels to gather the ingots to the chute 7 side with dogs 4. Next, a fluid pressure cylinder 12 operates to tilt the chute 7, thereby gliding the ingots 2 down to the stooper 7a of the chute 7. At the same time, a shifter 8 provided with a notched part 11 swivels to receive the ingot 2 at the leading end part in the part 11 and continues to swivel until it places the ingot on a conveying table 13, by which the ingot is transported to the heating furnace. By the swiveling of the shifter 8, the ingots 2 on the chute 7 are supplied automatically by each piece at a constant period to the heating furnace.

摘要： PURPOSE:To prevent accidents such as breakout by decreasing strokes when the resistance value generated in a mold exceeds a prescribed value and making stroke motion again when the resistance decreases. CONSTITUTION:A buffer mechanism 20 is provided between a mold vibrating table 1 and a driving source constituted of an electric motor 13 and a speed changer 12, and when abnormally large resistance is generated in the mold, vibration strokes change. The movements of an output shaft 15 are transmitted to the table 1 by the spring retainers 2, 4 at both ends of connecting bare 5, 5' receiving the repulsive forces of springs 6,7. Hence, if the vibration resistance of the mold is lower than the prescribed set pressure of the springs 6 and 7, there are no elongation and contraction of the mechanism 20, and a constant stroke is maintained. When the resistance higher than the set value is generated, the springs 6 and 7 are compressed and the stroke beings to decrease, and when it exceeds a certain value, the stroke is made zero, and the vibration stops despite running of the motor 13. When the resistance decreases, the vibration is started again.
摘要翻译：目的：当模具中产生的电阻值超过规定值时，通过减少冲程来防止诸如突破的事故，并且当电阻降低时再次进行行程运动。构成：在模具振动台1和由电动机13和变速器12构成的驱动源之间设置有缓冲机构20，并且当在模具中产生异常大的阻力时，振动行程发生变化。输出轴15的运动通过弹簧保持器2,4在接收弹簧6,7的排斥力的连接裸露5,5'的两端处传递到工作台1。因此，如果模具的抗振性低于弹簧6和7的规定设定压力，则机构20不会发生伸长和收缩，并且保持恒定的行程。当产生高于设定值的电阻时，弹簧6和7被压缩并且行程减小，并且当其超过一定值时，行程为零，并且尽管电动机13运行，振动停止。当电阻减小时，振动再次开始。

摘要： PURPOSE:To set the radius of bending of a curved mold small, and lower the height of a continuous casting installation by rolling a continuously cast ingot which is cast to a prescribed radius of curvature by the continuous casting installation with a pair of truncated circular cone shape rolls of a straightening device to make the shape of its cross section to a trapezoidal shape, and straightening the remaining curve with an ingot drawing unit. CONSTITUTION:A continuously cast ingot 5 molded by a curved mold 1 of a continuous casting installation is fed to a straightening device 3 by an ingot guide device 2, and is rolled synchronously from both right and left sides by a pair of truncated circular cone rolls 3a, 3a' to a trapezoidal shape in cross section. After this rolling and straightening, the ingot 5 has a slight curve remained therein, but the remained curve is finally straightened by an ingot drawing roll unit 4.

摘要： PURPOSE:To make maintenance work easy and operate a continuous casting plant under good environments by providing a dummy bar driving roll group serving also to screw down in an arbitrary position between the thermal equilibrium point and leveling point of an ingot in an ingot drawing part. CONSTITUTION:A dummy bar driving roll group 3 is disposed in a suitable place in the forward curving part of the leveling point of an ingot 7 between the outer side of a section wall 2a segmenting the secondary cooling area of a continuous casting plant from the outside part and an ingot drawing roll group 1. The respective inner rolls of this roll group 3 are driven by fluid pressure cylinders 6, and screw down the ingot 7 under suitable force. This area does not require spray cooling in the cooling process of the ingot 7 and is an area where the radiation heat of the ingot 7 balances with the transfer heat of the ingot only by the cooling effect of the heat radiation of the ingot 7. The drawing of the ingot 7 is accomplished mainly by the next drawing roll group 1. Thereby, the dummy bar 4 is set short and the pulsating drawing of the ingot in the initial period of pouring is eased.

摘要： PROBLEM TO BE SOLVED: To provide an alarming system which is applied to a continuous caster of a steel and predicts the danger of developing breakout. SOLUTION: In the continuous caster for continuously casting molten steel 12 in a mold 1, a cooling water quantity F, inlet cooling water temp. T1 and outlet cooling water temp. T2 of the mold 1 and drawing velocity V of a cast slab 14 are always measured and inputted to a computer 10. Together with this, an average solidified shell thickness (da) formed in the mold is obtd. through the operation by the equation da=F(T2 -T1 )/k.v based on the precalculated factor K from a casting condition of casting size, kind of steel, etc., and physical value of the steel. Further, the min. solidified shell thickness is obtd. from an unevenness and compared with a breakout developing limit solidified thickness. At the time of becoming near the breakout developing limit solidified thickness, the alarm for the increase of the danger of developing the breakout is sounded.
