Intermediate frequency furnace is an energy-saving equipment, but it is the focus of energy-saving enterprises in the enterprise, "per ton of qualified power consumption forgings" is to check it out of the resistance or not indicators. Therefore, there is no flaw in the energy-saving equipment itself, the impact of unit energy consumption of qualified products is too large a factor, is the energy-saving breakthrough. According to the situation in our factory, energy-saving ways in the cheek stove in what ways? Because of Frequency heating furnace to adapt to the needs of production, energy saving should focus on production management, operation technology, production technology, reduce waste rate and other efforts, the following energy saving ways for an analysis. 1. Product factors: From the product factor, the core for the qualified forgings more u =, the more simple the degree of processing, the higher the thermal efficiency. For example, under the line because there is no core material, cut after heating on the line, so the thermal efficiency is high, the molding process of the production line more complicated, as well as core, the thermal efficiency is low. Industry is not the same, the thermal efficiency of IF furnace is not the same. Bearing industry relative to the gear and automotive manufacturing industry, due to gear and crankshaft processing without pouring core, the thermal efficiency is higher than the bearing industry. 2. Management factors: From the management point of view, the production line staffing, equipment management, operation technology, product management are all related factors. Because each high-yielding line is a collective operation, which station on a problem or a pause, will affect the normal production across the board. Staffing is not appropriate, the sense of responsibility is not strong, with the work is not understanding, prone to error, equipment management is not good, so More barriers, it is easy to produce pause, poor operating skills, inconsistent with each other, the level of mold adjustment is low, can not do it. All these can take care of, the production is smooth, and the output is high and the quality is good too. On the contrary, not only did not survive. Quality is poor, and more than semi-finished products, to be heated again after production. Had a heating molding, heating is required to shape the second, with rework, the total amount of about 20% of all forgings. Therefore, the weighted average thermal efficiency of the five molding lines is 41.44%, which is relatively low. If you remove the two heating factors, å‰ can increase the thermal efficiency of 9.8%, such as saving all can save 204,000. 3. Waste factors: The high rejection rate is another important factor contributing to the low thermal efficiency. As a result of the use of more migrant workers, the overall operation level has dropped, resulting in a higher rejection rate. Only five molding lines, the total weight of scrap 220T steel to the weighted average thermal efficiency of 51% to calculate the need to consume 112,000 degrees. If scrap is reduced by 50% on an existing basis, the thermal efficiency can be increased by 3%; electricity savings by 56,000 degrees. 4. Process factors: Due to the impact of the production process, the bearing ring in the forging in the core is relatively large, and some core than the product weight, thermal efficiency must be low. Press line is very typical, material utilization rate of only 51.6%. Nearly half of the material threw, so the thermal efficiency of 21.66%. Such as improving the process, such as pressure expansion line, then the thermal efficiency can be increased to 42.7%. 3%. Pressing line processing range and small line similar to the same line and the same technology and equipment, the thermal efficiency can be increased to 52.3%. If you press the thermal efficiency of small lines, only this one line can save 200,000 degrees. This shows that a business process and equipment is not advanced, even if the application of energy-saving equipment, the energy waste is still considerable. 5 heating rate: Intermediate frequency furnace in a certain power to increase the heating rate, it should be possible to reduce the thickness of induction bushings, bush diameter and the diameter of the billet as low as possible. The current foreign level of 1.2: 1, the best level of our plant is 1.6: 1, the ratio of decline can reduce the magnetic flux leakage, increase the heating rate and increase the production pace. I plant molding line heating rate to meet the production pace and process requirements, but 250T shearing machine and press the two lower feed line, heating compliance can not reach the production pace of the need to wait for the diathermy process, the bar Loss of heat larger. If you can improve the heating degree, then the thermal efficiency can be increased. (IF furnace)
