In the mining industry, one of the challenges is which features of the thermic lance will be utilized mostly, and also which lance pipes are used in which the refining process is end-users consideration. Thermic lances are used in copper mines to replace parts of large shovels, to cut consumable parts of large excavators, and to reuse as scrap in various cases. Ideally, each agent should have a good understanding of the lance pipes used in which production processes (both mining and refining). In this blog, we are going to introduce the use of SC lances and thermic lances for taphole drilling in the copper smelting process, so that you can understand the use of lance pipes in the smelting process.

Drilling the Pin to Replace Parts of Large Shovels in Copper Mine

Copper mining is mostly done by accessible mining, which involves digging a succession of stepping platforms further and deeper into the soil over the period. Drilling equipment is employed to drill holes further into the stone to extract the ore, and dynamite is injected into the openings to blast and destroy the rock.

Workers will mostly employ excavators or concrete demolition hammers to demolish inner walls, construction, buildings, the ore bins from mine closures, and so on. However, owing to unique regions, building harnesses, and concrete construction, employing certain tools and equipment would be difficult for operators. As a result, adopting a stronger flame caused by thermic lance steep pipes would be the correct solution to handle the concrete destruction scenario.

Thermic Lance is a steel pipe with inserted wires, or wires and inner pipe that are to be used for fusing the metals and so on. The principle is that harness the oxidation heat of high temperature by providing the pressurized oxygen inside an ignited steel tube. Generally, the metal tube contains steel wire that promotes combustion.

Cutting Consumable Parts of Large Excavators

Excavator baskets are built from a variety of metals that provide hardness to make excavators last longer and hardly wear out. The materials are required depending on the part's capacity and production technique.

Excavator pins are often constructed of AISI 4130 or 4140 steel, which promotes corrosion resistance and toughness whereas molybdenum boosts surface hardness. The container sidewalls and forefront are often composed of AR360 and AR400 alloys which have been properly hardened to produce products with exceptional fracture toughness and strong tensile properties. The bucket shell is frequently manufactured of ASTM A572 Grade 50 (also known as A-572-50), a high-strength, low-alloy steel.

Due to the hardness of excavators, whenever users want to cut them into pieces for removing process, having applicable oxygen lance pipes with extremely strong heat would be the initial requirement. Many users choose to use Thermic Lance as the optimal option to enhance the performance of cutting those tough parts of excavators.

The correct angle to operate Thermic Lance is also a crucial part of enhancing its performance of the Thermic Lance. We also support our customers with the full instruction of the "Step-by-step Guide to Operate Thermic Lance with Safety and Effectiveness", here.

Taphole Drilling in Copper Smelting Process

The taphole, which is placed just above the bottom of the furnace's hearth, is used to extract slag and molten steel from the furnaces. Furnace tapped is the technique used to remove slag and heat sources from the heart of a furnace. For the purpose of taphole drilling, we recommend our customers use the oxygen lance pipe named SC Lance which can suit the required performance and cost savings.

DAIWA SC LANCE is a mild steel oxygen lance pipe made with HRC (Hot Rolled Steel Sheet in the coil), welded by high-frequency welding equipment, there is no oil, and no grease on the pipe. DAIWA SC LANCE generates a high temperature of over 3,000℃ by blowing oxygen and melting solidified steel, and slag on equipment.

Conclusion

By using Daiwa Lance pipes, there are also other various impacts that could support and bring to the whole steel production process. Beside steel production process, Daiwa Lance also can apply various types of oxygen lance pipes that can use for other purposes.
