Description

Technical Field

[0001] The present invention relates to the field of billet continuous casting production equipment, and in particular to a continuous casting machine translation control system and a continuous casting machine. Background Art

[0002] The ingots produced by the billet continuous casting machine need to be cooled and straightened on a cooling bed. Currently, most cooling beds are step-beam cooling beds. The forward and backward movement of the cooling bed is controlled by time; the horizontal movement of the cooling bed is synchronized by a synchronous motor. This control method has the following defects: 1. Within the specified time, if the forward or backward movement has not reached the specified data, it will be forcibly stopped and the next action will be performed. This causes small errors to accumulate into large errors, eventually paralyzing the cooling bed. 2. The control components are single, and only one set of control components is used to control the translation of the cooling bed. When the control components fail, the cooling bed cannot be used and production is forced to stop.

[0003] In view of this, this application is hereby filed. Summary of the Invention

[0033] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0034] Please refer to Figure 1 This embodiment provides a continuous casting machine translation control system 100, which includes a first hydraulic cylinder 111, a second hydraulic cylinder 112, a first hydraulic lock 121, a second hydraulic lock 122, a first rodless cavity oil supply pipeline 130, a second rodless cavity oil supply pipeline 150, a first rod cavity oil supply pipeline 140, a second rod cavity oil supply pipeline 160, a control system, a main control mechanism and an auxiliary control mechanism.

[0035] The output ends of the first rodless chamber oil supply pipeline 130 and the second rodless chamber oil supply pipeline 150 are both in communication with the rodless chamber of the first hydraulic cylinder 111 and the rodless chamber of the second hydraulic cylinder 112 .

[0036] When the continuous casting machine translation control system 100 is installed on the cooling bed, the first rodless cavity oil supply pipeline 130 and the second rodless cavity oil supply pipeline 150 of the continuous casting machine translation control system 100 are connected to the rodless cavity oil supply pipe 11, which is used to supply hydraulic oil to the rodless cavities of the first hydraulic cylinder 111 and the second hydraulic cylinder 112.

[0037] The output ends of the first rod chamber oil supply pipeline 140 and the second rod chamber oil supply pipeline 160 are in communication with the rod chamber 101 of the first hydraulic cylinder 111 and the rod chamber 101 of the second hydraulic cylinder 112 .

[0038] When the continuous casting machine translation control system 100 is installed on the cooling bed, the first rod chamber oil supply pipeline 140 and the second rod chamber oil supply pipeline 160 of the continuous casting machine translation control system 100 are connected to the rod chamber oil supply pipe 12, which is used to supply hydraulic oil to the rod chamber 101 of the first hydraulic cylinder 111 and the second hydraulic cylinder 112.

[0039] The first hydraulic lock 121 is provided near the first hydraulic cylinder 111 and is used to cut off the passages connecting the first rodless chamber oil supply line 130, the second rodless chamber oil supply line 150, the first rod chamber oil supply line 140, and the second rod chamber oil supply line 160 with the first hydraulic cylinder 111. The second hydraulic lock 122 is provided near the second hydraulic cylinder 112 and is used to cut off the passages connecting the first rodless chamber oil supply line 130, the second rodless chamber oil supply line 150, the first rod chamber oil supply line 140, and the second rod chamber oil supply line 160 with the second hydraulic cylinder 112. The hydraulic lock can lock the oil in the corresponding hydraulic cylinder, ensuring that the oil cylinder stops at the set position and prevents it from moving.

[0040] The main control mechanism includes a proportional valve 171 and a diverter and collector valve 172. The proportional valve 171 is arranged on the first rodless chamber oil supply pipeline 130 and the first rod chamber oil supply pipeline 140, and is close to the input end of the first rodless chamber oil supply pipeline 130 and the input end of the first rod chamber oil supply pipeline 140; the diverter and collector valve 172 is arranged on the first rodless chamber oil supply pipeline 130, and is located between the proportional valve 171 and the output end of the first rodless chamber oil supply pipeline 130. The first rodless chamber oil supply pipeline 130 includes two first rodless chamber oil supply branch pipelines 131, and the two first rodless chamber oil supply branch pipelines 131 are respectively connected to the rodless chamber of the first hydraulic cylinder 111 and the rodless chamber of the second hydraulic cylinder 112.

[0041] The proportional valve 171 is preferably a three-position, four-way electro-hydraulic directional valve 191 with a "Y" type neutral position function. Its working principle is to gradually increase and decrease the opening of the solenoid valve 192 by controlling the valve core of the solenoid valve 192 to gradually increase and decrease the opening, so that the cooling bed can start slowly, accelerate uniformly, advance and retreat uniformly, decelerate uniformly, and stop slowly during the translation process, thereby avoiding the impact caused by the start and stop and reversing of the hydraulic system and protecting the equipment. The diverter and collector valve 172 evenly divides the hydraulic oil entering the two hydraulic cylinders and plays a synchronous role.

[0042] Preferably, the first rod chamber oil supply pipeline 140 and the second rod chamber oil supply pipeline intersect, and the intersecting pipeline includes two rod chamber oil supply branch pipelines 103, which are respectively connected to the rod chambers 101 of the first hydraulic cylinder 111 and the second hydraulic cylinder 112, and a first throttle valve 104 is provided on each of the two rod chamber oil supply branch pipelines 103; a second throttle valve 105 is provided on the first rodless chamber oil supply pipeline 130, and the second throttle valve 105 is provided between the proportional valve 171 and the diverter and collector valve 172.

[0043] The purpose of setting the first throttle valve 104 and the second throttle valve 105 is to limit the oil intake of the cooling bed translation system, control the maximum speed of the cooling bed translation, and avoid excessive speed and large impact.

[0044] The auxiliary control mechanism includes a reversing valve 191, two solenoid valves 192, and a first position sensor 181 and a second position sensor 182 respectively arranged on the first hydraulic cylinder 111 and the second hydraulic cylinder 112; the reversing valve 191 is arranged on the second rod chamber oil supply pipeline 160 and the second rodless chamber oil supply pipeline 150, and is close to the input end of the second rod chamber oil supply pipeline 160 and the input end of the second rodless chamber oil supply pipeline 150, the second rodless chamber oil supply pipeline 150 is located between the output end of the reversing valve 191 and the second rodless chamber oil supply pipeline 150 and includes two second rodless chamber oil supply branch pipelines 151, the two second rodless chamber oil supply branch pipelines 151 are respectively connected to the rodless chamber of the first hydraulic cylinder 111 and the rodless chamber of the second hydraulic cylinder 112, and the two solenoid valves 192 are respectively arranged on the two second rodless chamber oil supply branch pipelines 151;

[0045] The reversing valve 191 is preferably a three-position four-way electromagnetic reversing valve 191. Its function is that when the moving speeds fed back by the position sensors of the two cooling bed translation hydraulic cylinders are inconsistent, the reversing valve 191 responds to the control system command to be energized and supplies oil to the hydraulic cylinder with slower moving speed, so that the moving speeds of the two cooling bed translation hydraulic cylinders are consistent.

[0046] The two solenoid valves 192 are preferably two-position two-way solenoid valves 192. When the position sensor detects that the speed of a hydraulic cylinder is relatively slow, it will be energized at the same time as the three-position four-way solenoid reversing valve 191 to supply oil to the cooling bed translation hydraulic cylinder with slow moving speed, ensuring that the moving speed of the two cooling bed translation hydraulic cylinders is consistent.

[0047] Preferably, a third throttle valve 152 is provided on each of the two second rodless chamber oil supply branch lines 151. The third throttle valve 152 is located between the solenoid valve 192 and the reversing valve 191 on the corresponding line. The function of the two third throttle valves 152 is to correspondingly limit the amount of oil entering the two-position two-way solenoid valve 192 to ensure smooth movement of the cooling bed.

[0048] The first position sensor 181 and the second position sensor 182 are communicatively connected to the control system, and the proportional valve 171, the diverter and collector valve 172, the reversing valve 191, and the two solenoid valves 192 are all communicatively connected to the control system; the control system is configured to control the main control mechanism to move the first hydraulic cylinder 111 and the second hydraulic cylinder 112, and is configured to receive signals from the first position sensor 181 and the second position sensor 182. When the signals indicate that the moving speeds of the two hydraulic cylinders are inconsistent, instructions are sent to the auxiliary control mechanism to make the moving speeds of the two hydraulic cylinders consistent.

[0049] The cooling bed main control mechanism and the cooling bed auxiliary control mechanism adopt position control. Only after the cooling bed is translated to the set position data can the next action be executed. Under normal conditions, the cooling bed main control mechanism independently controls the operation of the cooling bed translation hydraulic cylinder. When the speeds of the two cooling bed translation hydraulic cylinders are inconsistent, the position sensor built into the hydraulic cylinder transmits data to the control system. The control system issues an auxiliary control instruction to the cooling bed auxiliary control mechanism. According to the data transmitted by the position sensor, the three-position four-way electromagnetic reversing valve 191 of the cooling bed auxiliary control mechanism is instructed to be energized. At the same time, the corresponding two-position two-way electromagnetic valve 192 installed on the oil circuit of the cooling bed translation hydraulic cylinder is also energized to assist in supplying oil to the slower moving cooling bed translation hydraulic cylinder, so as to achieve the same speed of movement of the two cooling bed translation hydraulic cylinders.

[0050] If the cooling bed main control mechanism fails and the auxiliary system cannot correct the problem, the oil inlet and outlet valves of the cooling bed main control mechanism can be cut off, allowing immediate repair of the cooling bed main control mechanism. The control system switches the control mode, making the cooling bed auxiliary control mechanism the cooling bed control system, thus avoiding production stoppages caused by control system failures.

[0051] Furthermore, a first stop valve 141 and a second stop valve 153 are respectively provided on the first rod chamber oil supply pipeline 140 and the second rod chamber oil supply pipeline 160. The first stop valve 141 is located before the proportional valve 171 and the intersection pipeline; the second stop valve 153 is located before the reversing valve 191 and the intersection pipeline.

[0052] A third stop valve 132 is provided on each of the two first rodless chamber oil supply branch pipelines 131 .

[0053] A fourth shut-off valve 154 is provided on each of the two second rodless oil supply branch pipelines. Each fourth shut-off valve 154 is located between the solenoid valve 192 and the hydraulic cylinder on the corresponding pipeline.

[0054] A fifth stop valve 173 is provided on the first rodless chamber oil supply line 130 at the front end of the proportional valve 171 , and a sixth stop valve 193 is provided on the second rodless chamber oil supply line 150 at the front end of the reversing valve 191 .

[0055] The settings of all the above-mentioned stop valves can cut off the oil circuit during maintenance.

[0056] The embodiment of the present application provides a continuous casting machine, including the continuous casting machine translation control system 100 provided in the embodiment of the present application. Since the continuous casting machine includes the control system provided in the embodiment of the present application, the cooling bed translation synchronization can be ensured.

[0057] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
