In the process of metal melting, a large amount of scum will be produced, which will float and condense on the surface of hot metal. If the scum is not removed, the quality of the casting will be affected. At present, the traditional slag extraction method mainly used in the casting industry not only has great personal safety risks, but also has very large labor intensity, very low work efficiency and much loss of hot metal. The current product, slag extraction machine, has been applied to a number of casting enterprises, received the unanimous praise of users, the CT series intelligent slag extraction machine developed by our company is bound to replace the traditional slag extraction model, which is also the general trend of the casting industry to move forward.
The main body of the equipment adopts the bottom rotating rocker arm structure: 1. The rotation of the rocker arm is controlled by the frequency conversion motor and can rotate 360 degrees (the speed is adjustable); 2• The expansion and contraction of the auxiliary arm is controlled by the cylinder; 3• The gripper rotation is controlled by the cylinder and can be rotated independently at 90 degrees; 4• The rise and fall of the gripper and the grasping action of changing hands are controlled by the cylinder; The base, column, rocker arm and telescopic arm of the equipment are hard connected to the overall structure, which is safe and reliable. Two electric furnaces share an intelligent slag extraction machine (one tow two), the intelligent slag extraction machine is installed in the middle position of the two electric furnaces platform, the slag extraction operator can control the slag extraction robot through the field operation equipment console or the field operation remote control sensor handle two ways.
Second, the main advantages of the equipment
1, easy to install, no need to transform the original field equipment, small footprint.
2, the layout is reasonable, the equipment adopts the bottom rotating rocker arm structure, the manipulator telescopic arm is fixed, and the gripper structure is independently rotating design.
3, safe and reliable, the use of ester type flame retardant liquid as a power source, good lubrication, flame retardant, grab greater strength, more stable.
4, easy to operate, the equipment adopts manual and remote control dual operation mode, which is safer and more reliable than manual standing on the side of the stove.
5, reliable performance, all materials of the equipment are designed and manufactured with high temperature resistance, and electrical components are made of Siemens & Schneider; Assembly parts are used in the world reliable, or domestic.
Three. Application benefit analysis
1. Safety
1 Equipment installation layout is reasonable, the structure of the bottom rotating rocker arm structure, increase the stability of equipment operation, open the working space around the furnace, reduce the danger caused by tripping, the staff only need to stay away from the high temperature furnace through the remote control to avoid various dangers caused by close operation, all the rotating parts are equipped with fixed protective cover, Therefore, safety is fully guaranteed.
2 Using the equipment through remote control of long-distance slag, to avoid the hot metal liquid in the process of melting of electric furnace heat radiation damage to the body, and greatly reduce the labor intensity of the operator, only one person can easily complete the large electric furnace slag fishing operation.
3 Because manual dreg is a (high risk, high temperature, high intensity) work, now workers are not willing to engage in this work, with Qingzhou Chentai Machinery equipment Technology Co., Ltd. R & D and production of CT series intelligent dreg machine, workers work easier, the working environment is greatly improved, workers are willing to engage in this work.
2. Energy saving
Shorten the residence time of hot metal in the furnace caused by manual dregs, under normal circumstances, the amount of 12 tons of electric furnace slag is more than 200 kilograms, and the manual slag extraction needs three to four people, and the labor intensity is large, the slag picking time is long, the manual generally takes more than 15 minutes; The use of the slag robot, only one worker through the remote control can be operated, the slag can be cleaned up in about three minutes, each furnace can save more than ten minutes, reduce the residence time of hot metal in the furnace, improve production efficiency, greatly reduce power consumption, and greatly reduce production costs.
3. Environmental Protection
The whole set of equipment adopts ester type flame retardant hydraulic fluid as power source, good flame retardancy, safety and environmental protection.
4. Other advantages
① The technical quality requirements of the operating position are reduced, and each set (one tow and two electric furnaces) only needs 1 person, reducing the number of operators.
(2) The slag can be directly extracted without adding slagging agent, and the slagging agent can be saved by more than 60%.
③ The mechanical gripper adopts a special process design, which increases the action of dripping and squeezing the hot metal in the process of dredging, effectively reduces the hot metal being taken out with the slag, and greatly reduces the waste of hot metal and the transfer of waste slag.
Due to the shortening of slag extraction time, the number of single-shift melting furnaces is increased, which not only saves a lot of power but also improves efficiency.
⑤ The use of the equipment can reduce the damage to the lining due to the artificial lifting of the slag, reduce the cost of later repair of the furnace, and greatly improve the service life of the furnace.
⑥ Investment in this equipment can recover the cost in the short term, an investment, long-term benefit.
