[0014] A multi-stream continuous casting and hot delivery method comprises the following steps

[0015] Step 1: The ingot is sent to the billet discharge roller through the previous process, and the lifting baffle on the billet discharge roller is in a high position at this time; when the ingot passes the signal roller on the billet discharge roller, the signal roller sends a signal to the PLC controller, and the PLC controller sends a command, the ingot stops at the front end of the lifting baffle and the lifting baffle drops to a low position, and the numbering machine starts to number the end of the ingot. After the numbering machine is finished, it sends a signal to the PLC controller, and the PLC controller controls the steel scooping machine to move to the top of the ingot that has been numbered, and scoops up the ingot that has been numbered. If the ingot needs to be offline normally, proceed to step 2; if the hydraulic steel drawing machine fails or a single ingot has quality problems, proceed to step 3; if the ingot needs to be hot delivered, proceed to step 4;

[0016] Step 2: The billet is placed on the billet placement position of the hydraulic steel drawing machine through the steel scooping machine. After the billet is placed, the first billet detection device of the hydraulic steel drawing machine sends a signal, and the hydraulic cylinder of the hydraulic steel drawing machine starts to move, pulling the billet away from the billet discharge roller. The steel scooping machine continuously places the billet, and the hydraulic steel drawing machine gathers multiple billets at the end of the hydraulic steel drawing machine, and then the billet is unloaded;

[0017] Step 3: The steel scooping machine places the ingot on the accident hydraulic steel drawing machine; the ingot detection device detects the signal and sends a signal to the PLC controller, and the PLC controller controls the hydraulic cylinder of the hydraulic steel drawing machine to start moving, pulling the ingot away from the billet discharge roller, and gathering the ingot at the end of the hydraulic steel drawing machine, and then unloading the ingot;

[0018] Step 4: Place the ingot on the first set of hot delivery rollers through the steel scooping machine. At this time, the ingot detection device sends a signal of ingot presence to the PLC controller, and the PLC controller issues an instruction not to allow the steel scooping machine to place the ingot again; when the ingot detection device displays a signal of no ingot presence, the first set of hot delivery rollers and the second set of hot delivery rollers simultaneously run forward to send the outgot to the second set of hot delivery rollers, and at this time, the fourth ingot detection device sends a signal of ingot presence to the PLC controller; when the ingot on the second set of hot delivery rollers needs to continue to be transported to the third set of hot delivery rollers, enter step 5, and when the ingot on the second set of hot delivery rollers needs to be unloaded onto the loading and unloading platform, enter step 6;

[0019] Step 5: When the fifth casting detection device displays no casting signal, the second group of hot delivery rollers and the third group of hot delivery rollers simultaneously run forward to deliver the outgoing casting to the third group of hot delivery rollers. When the fifth casting detection device displays a casting signal, the second group of hot delivery rollers stops delivering the casting and waits for the subsequent rolling mill process to take away the casting on the third group of hot delivery rollers before delivering the casting again.

[0020] Step 6: The billet taker is in the original position, that is, close to the second set of hot delivery rollers and lower than the roller surface of the hot delivery rollers. When the billet is in place and ready to be unloaded, in the first step, the lifting cylinder of the billet taker extends to lift the billet; in the second step, the translation cylinder of the billet taker retracts to transport the billet to the top of the billet placement position of the loading and unloading platform; in the third step, the lifting cylinder of the billet taker retracts to place the billet on the billet placement position of the loading and unloading platform; in the fourth step, the translation cylinder of the billet taker extends, and the billet taker returns to the original position, waiting for the next billet unloading;

[0021] Step 7: After step 6 is completed, the billet detection device sends a billet signal, the oil cylinder of the loading and unloading platform is started, and the billet is pulled from the front end to the end of the loading and unloading platform, so that the billet is gathered at the end of the loading and unloading platform, waiting for the billet to come off the line;

[0022] Step 8: When the cold billets on the loading and unloading platforms need to be put on line, the original position of the billet unloading machine is the billet placement position of the loading and unloading platforms and is lower than the rail surface of the loading and unloading platforms; after the billets are in place, in the first step, the lifting cylinder of the billet unloading machine extends to lift the billets; in the second step, the translation cylinder of the billet unloading machine extends to transport the billets to the top of the billet placement position of the second set of hot delivery rollers; in the third step, the lifting cylinder of the billet unloading machine retracts to place the billets on the second set of hot delivery rollers; in the fourth step, the translation cylinder of the billet unloading machine retracts, and the billet unloading machine returns to its original position, waiting for the next billet unloading.

When the billets need to be taken off the line normally, the scooping machine 3 sends the scooped billets to the billet placement position of the hydraulic steel drawing machine 4.

[0072] Step 5: When the fifth casting detection device 96 displays no casting signal, the second set of hot delivery rollers 92 and the third set of hot delivery rollers 93 simultaneously run forward to deliver the outgoing casting to the third set of hot delivery rollers 93. When the fifth casting detection device 96 displays a casting signal, the second set of hot delivery rollers 92 stops delivering the casting and waits for the subsequent rolling mill process to remove the casting on the third set of hot delivery rollers 93 before delivering the casting again.

[0073] Step 6: The billet taking machine 10 is in the original position, that is, close to the second set of hot delivery rollers 92 and lower than the roller surface of the hot delivery rollers 9. When the billet is in place and needs to be unloaded, in the first step, the lifting cylinder of the billet taking machine 10 extends to lift the billet; in the second step, the translation cylinder of the billet taking machine 10 retracts to transport the billet to the top of the billet placement position of the loading and unloading platform 11; in the third step, the lifting cylinder of the billet taking machine 10 retracts to place the billet on the billet placement position of the loading and unloading platform 11; in the fourth step, the translation cylinder of the billet taking machine 10 extends, and the billet taking machine 10 returns to the original position to wait for the next billet taking;

[0074] Step 7: After step 6 is completed, the billet detection device 111 sends a billet signal, and the oil cylinder of the loading and unloading platform 11 is started to pull the billet from the front end to the end of the loading and unloading platform 11, so that the billet is gathered at the end of the loading and unloading platform 11, waiting for the billet to come off the line;

[0075] Step eight: when it is necessary to put the cold billets on the loading and unloading platform 11 onto the production line, the original position of the billet unloading machine 10 is the billet placement position of the loading and unloading platform 11 and is lower than the rail surface of the loading and unloading platform 11; after the billets are in place, in the first step, the lifting cylinder of the billet unloading machine 10 is extended to lift the billets; in the second step, the translation cylinder of the billet unloading machine 10 is extended to transport the billets to the second set of hot delivery rollers 92 above the billet placement position; in the third step, the lifting cylinder of the billet unloading machine 10 is retracted to place the billets on the second set of hot delivery rollers 92; in the fourth step, the translation cylinder of the billet unloading machine 10 is retracted, and the billet unloading machine 10 returns to its original position, waiting for the next billet unloading.
