The slag-dredging robot ,The electric furnace slag extractor is suitablefor medium frequency furnaces ranging from 1ton to 120 tons,Ladle slagging operation,
It can be used for smelting and cleaning slag of steel, iron, copper and various non-ferrous metals by hand During the melting process of medium
frequency electric furnaces, a large amount of dross will be generated and float on the Surface of the molten iron. If this dross is not removed, it will affect the quality of the castings. At present, the method of slag-picking in the domestic foundry industry is relatively traditional - slag-pickers wear
protective gear and stand close to the furnace mouth, using long iron forks to pick up slag from outside the furnace.
The sparks and molten iron splashing around are very unsafe. The temperature of molten iron in the furnace can reach more than 1600 degrees Celsius, and the temperature around the furnace mouth can reach several hundred degrees Celsius. Especially in summer, the temperature of the furnace mouth is even higher, and the working environment is very harsh; Desulfurization slag has strong adhesion, and the slag is very heavy when it is gathered together . It is very labor-intensive to manually pull out the slag, and it takes many times to pull out the desulfurization slag completely, resulting in very low work efficiency; During slag removal, a lot of molten iron will adhere, resulting in a large amount of waste of raw materials
The CT series intelligent slag extractor developed by our company is bound to replace the traditional slag extraction mode, which is also the general
trend of the development of the foundry industry.
The main body of the equipment adopts a bottom rotating rocker arm structure:
1. The rotation of the rocker arm is controlled by a variable frequency motor, allowing for 360-degree rotation (with adjustable speed);
2. The extension and retraction of the auxiliary arm is controlled by the oil cylinder;
3. The rotation of the gripper is controlled by the oil cylinder and can rotate independently by 90 degrees;
4. The lifting and lowering of the gripper and the grasping action of the hand are controlled by the oil cylinder;
The equipment base, column, rocker arm, and telescopic arm are hard-wired as a whole structure, which is safe and reliable. Two electric furnaces share one intelligent slag-dredging machine (one-to-two), which is installed in the middle of the two electric furnace platforms. The slag-dredging operators can control the slag-dredging robot to carry out slag-dredging operations through two methods: on-site operation of the equipment console or on-site operation of the remote control sensor handle.
II. Main advantages of the equipment
1. Easy to install, no need to modify the original on-site equipment, and small footprint.
2. The layout is reasonable, and the equipment adopts a bottom rotating rocker arm structure, with a mechanical arm fixed by a telescopic arm, and a gripper structure with independent rotation design.
3. Safe and reliable, using ester-type flame retardant liquid as a power source, good lubrication, flame retardant, greater grasping force, and more stable.4. Easy to operate, the equipment adopts manual and remote control dual operation modes, which is safer and more reliable than manual operation from the side of the furnace.
5. Reliable performance, all materials of the equipment are designed and manufactured with high temperature resistance,All assembly parts are either sourced from globally reliable suppliers or are domestic products.
III. Analysis of Application Benefits
1. Security The equipment is installed and arranged reasonably, with a bottom rotating rocker arm structure, which increases the stability of the
equipment operation, expands the working space around the furnace, and reduces the potential hazards caused by tripping. Workers only need to stay away from the high-temperature furnace mouth and operate through a remote control to avoid various dangers caused by close-range operations. All rotating parts are equipped with fixed protective covers, so safety is fully guaranteed.
2. Using this equipment to remotely control the remote slag removal process through remote control avoids the thermal radiation
damage to the body caused by high-temperature metal liquid during the electric furnace smelting process, and greatly reduces the labor intensity of operators. Only one person can easily complete the slag removal operation of a large electric furnace with independent operation.
