Extra-Large Size TCM (1550mm)
The BGT type extra-large size torch cutting machine is mainly used for cutting the riser of extra-large steel ingot (thickness more than 1000mm) and casting steel pieces, which is particularly suitable for large casting pieces and forging pieces manufacture.
Under usual situation, the casting riser of extra-large ingot or casting piece shall be cut after cooling, a lot of thermal energy will be wasted during cooling process, and normally the riser cutting time will last over ten hours or even one whole day. Before the ingot or casting piece goes to forging machine, it shall be re-heated to over 1100℃ in heating furnace, this re-heating process will consumes a lot of gas energy. Thus, cutting riser of ingot or casting piece by saw is inefficient and energy-wasting technology.
Xinzhong’s BGT type extra-large size torch cutting machine can cut the ingot or casting piece under high temperature after it disconnected from mould, although the cutting process also needs to consume some gas, but torch cutting machine is of high efficiency, each piece can be cut within 40-60 min, and the time and energy of re-heating process is less, so the actual working efficiency is greatly improved with less energy consumption. Take Φ1000 ingot for example, the difference between two cutting modes are as below:
| Riser cutting mode | Saw cutting | Torch cutting |
| Cutting time | 20-24 h | 40-60 min |
| Cutting condition | Cold cutting | Hot cutting |
| Re-heating time | Long | Short |
