摘要： PROBLEM TO BE SOLVED: To provide a plate thickness reduction equipment capable of efficiently executing rolling down forming of a material to be formed in the direction of plate thickness. SOLUTION: In a thickness reduction press 5, a material to be formed 1 heated by a heat-reserving heating furnace 4 is rolled down in the direction of plate thickness with a plurality of metallic dies 30a, 30b, 33a and 33b arranged along a transfer line S, and a part of the material 1 subjected to rolling down forming by the thickness reduction press 5 is rolled down in the direction of plate thickness by work rolls 6a, 6b of a roughing roll 7. Further, the part of the material 1 subjected to rolling down forming by the thickness reduction press 5 is loosened downward by a looping mechanism 8 to absorb a forwarding motion of the material 1 owing to reduction of plate thickness of the material 1 by the thickness reduction press 5.

摘要： PURPOSE:To prevent thermal deformation and to facilitate the control of heat extraction efficiency by juxtaposing plural cooling fluid passages near the casting surface part in a block. CONSTITUTION:The plural cooling fluid passages 3 are juxtaposed at prescribed intervals near the rear of the casting surface 2 in the block 1. Belt-like parts 4 are constituted between the passages 3 and the casting surface 2 to about several mm - thickness (t). Such blocks 1 are connected to an endless shape to constitute a casting mold of a block type continuous casting machine. The surface 2 which contacts with a molten metal extracts the heat from the molten metal by the heat conduction in the belt-like parts 4. The control of the heat extraction efficiency of the mold is made easy by adjusting the flow rate of the cooling fluid in the passages 3. The thickness and rigidity over the entire part of the block 1 are maintained and therefore the thermal deformation thereof is prevented. The prevention of the thermal deformation and the easier control of the heat extraction efficiency are made possible by the above-mentioned method.

摘要： PURPOSE:To prevent the breakout occurring in the defective extraction of heat by adjusting four sets of mold constituting bodies so as to narrow the bodies relative to each other in order to reduce gradually the section of a casting space from the pouring inlet side toward the outlet side by as much as the shrinkage on solidification of a molten metal is allowed for. CONSTITUTION:The mold constituting bodies 1, 2, 3, 4 are combined to a frame shape to form the casting space S of the square shape in section continuous from the molten metal inlet side toward the outlet side. The molten metal is poured into the space S and is continuously cast. The bodies 1-4 are adjusted to narrow relative to each other by adjusting mechanisms 5, 6, 7, 8 so that the section of the space S decreases gradually from the pouring inlet side toward the outlet side by as much as the shrinkage on solidification of the molten metal is allowed for. The incident that the shell shrunk on solidification part from the constituting bodies 1-4 is thereby averted. The generation of the breakout occurring in the defective extraction of heat or nonuniformity is thus prevented.

摘要： PURPOSE:To grow a solidified shell to a uniform thickness and to prevent the generation of internal defects by measuring the thickness of the solidified shell in the transverse direction of a casting plate and changing the cooling condition in the transverse direction in accordance with the thickness thereof. CONSTITUTION:A temp. measuring unit 1 provided successively with many temp. sensors 5 is provided in the transverse direction of the casting plate 3 and the measuring signals from the sensors 5 are inputted to a control unit 4 which operates the temp. distribution in the transverse direction of the plate 3. The temp. in the thin part of the solidified shell where much of the unsolidified shell of the plate 3 is contained is high and the thickness distribution of the solidified shell is detected from the above-mentioned temp. distribution. A cooling unit 2 disposed with many cooling nozzles 6 in the transverse direction of the plate 3 in such a manner that the flow rates thereof can be discretely controlled is controlled in accordance with the thickness distribution, i.e., temp. distribution of the solidified shell to change the cooling condition in the transverse direction. The solidified shell is thus grown in the uniform condition and the generation of internal defects such as the internal segregation of impurities and hollows is prevented.

摘要： PURPOSE:To prevent generation of a solidified shell at the bottom end of an end mold and to improve the quality of a product by providing a molten metal pool preventive part constructed to project increasingly toward a bottom mold in the casting direction of a steel plate to the inside surface of an end mold. CONSTITUTION:The outermost flowing part of the molten metal 5 flows from the upper part on the inside surface of the end mold toward the lower part when the molten metal 5 is poured from a supply nozzle 4 into a gate. The molten metal flows along the curve of the molten metal pool preventive part 8 in the lower part in this state. The generation of exfoliation in the flow of the molten metal 5 is thus obviated and therefore the generation of a solidified shell owing to the molten metal pool is prevented.

摘要： PURPOSE:To avert the problem arising from the deviation in the insertion position of a nozzle by detecting the actual moving position of the nozzle mounted to a moving carriage by a sensor and adjusting the position of the nozzle by a position adjusting mechanism. CONSTITUTION:The sensor 10 detects the actual position of the nozzle 2 just before the nozzle 2 is inserted between moving molds 1. A position control section determines the posture of the nozzle 2 from the detection signal thereof. The position control section controls respective servocontrol actuators 6 to adjust the posture of the nozzle 2 to the intended posture. More specifically, a guide body 7 is displaced in lateral directions by the actuator 6 mounted to the guide body 7 to displace the nozzle 2 together with the moving carriage 4 to the right and left. The actuator 6 is associatedly extended and contracted to vertically move the nozzle 2 together with the moving carriage 4 or to move the same in all directions. The nozzle 2 is adjusted to the correct posture and is quickly inserted between the moving molds 1 in the above-mentioned manner.

The sensor 9 detects the stage just before the cavity is full of the molten metal when the inside of the cavity 8 is filled with the molten metal after starting of pouring. Then the sensor inputs a detection signal to a control device 10. The device 10 outputs a command signal 11 to operate the driving motors 1, 2 and the dummy bar 7 and starts the operation of the continuous casting machine at the same instant when the cavity 8 is full of the molten metal. The deterioration of the surface characteristic of the ingot and the rupture thereof are thereby eliminated.
