Electric furnace technical information（技术）
What should I do to get a higher furnace age for an intermediate frequency induction furnace? First of all, let's look at the measures to improve the service life of the electric furnace crucible. The following describes how to prevent the occurrence of defects from the aspects of furnace lining refractory materials, laying process, furnace building process, oven process and use process, so as to improve the service life of the electric furnace crucible.
1. The quality and performance of the furnace lining refractories play a fundamental role in the service life of the furnace.
2. The quality of the furnace is of great significance to the life and safety of the furnace. When laying the furnace, first check the coil for damage. If so, apply insulation paint to the damaged area to repair it; then use water glass to mix the refractory mud to smooth the furnace wall, and clean the furnace wall and the bottom of the furnace. Cut the size of the mica board, alarm stainless steel mesh, asbestos cloth; use the copper core wire to connect the alarm stainless steel net to pass out of the furnace coil, and then use three expansion rings to rise under the middle, top of the asbestos-lined furnace wall Tight; the paved stove should be covered to prevent debris from falling into it.
3. The oven is to obtain the sintered layer. The quality of the sintered layer directly affects the service life of the furnace. The oven is an important link.
4. The various processes of the furnace use process are also very important to the service life of the furnace. Improper operations may reduce the service life of the furnace.
In short, in order to obtain a higher furnace age for an intermediate frequency induction electric furnace, the following points must be achieved:
1) It is necessary to choose refractories with good performance, relatively pure ingredients and reasonable particle size ratio.
2) Check whether the coils are damaged before laying the furnace. When laying the furnace, install insulation boards, stainless alarm nets, and insulation boards.
3) The furnace building tools should be selected, and all preparations should be done before the furnace building, and the feeding amount and tamping time of each layer should be controlled, foreign objects should not fall into the furnace, and the crucible should be as solid and clean as possible.
4) The oven should pay attention to the heating speed to ensure that the water vapor of the furnace lining sand is slowly and completely discharged; when the quartz phase changes, the heating speed should be reduced or the heat should be kept so that it can slowly phase change to complete phase change.
5) Do a good job of various furnace processes to avoid the occurrence of defects.
