New steps for furnace operation of 1 ton series intermediate frequency furnace and new method for oven

(1) The thickness of the first feeding of 1 ton series intermediate frequency furnace should not exceed 80 ~ 100mm, and then each layer is 40 ~ 50mm, using flat head curved fork, repeating operation according to the front edge and the middle, and then using the flat hammer Tamper, do not hang the insulation layer.

(2) The bottom of the intermediate frequency furnace is tempered to be 20 to 30 mm higher than the required height of the bottom of the furnace (flat with the first coil below the induction coil), and flattened with a flat hammer, then raised with a spatula Partially clear out of the furnace and keep the bottom level.

(3) Model positioning. 1 Ensure that the mold is placed horizontally on the refractory material of the furnace bottom. 2 Find the center of the mold to ensure that the thickness of the furnace wall is uniform and concentric with the induction coil. 3 Use a wedge to fix the spacing between the die and the coil. 4 Put the pressure iron on the inner bottom of the mold to prevent uneven thickness of the lining caused by the floating and eccentricity of the mold.

(4) Construction of the furnace wall. 1 Each time the feeding is not more than 50 ~ 60mm thickness, it should be layered and layered, layer by layer (the knotting at the junction of the bottom and the wall is particularly careful). 2 The surface of the solid layer should be scraped and fed before each feeding. 3 Do not allow debris to fall into the feed, and do not pile up evenly. 4 The height and slope of the stencil should be checked continuously during the actual process. 5 After the end of the fight, scrape off the excess refractory material to the specified height.

(5) The furnace mouth and the mouth of the furnace are made of plastic material, and after the concrete is built, the black carbon mud is used to brush and vent the holes. The mouth of the furnace and the mouth of the furnace have little effect on the life of the lining. The water glass can be mixed with the binder. The mixture should not be too dry or too wet. First apply a proper amount of water glass at the mouth of the mouth and the finished furnace mouth, then fill in the mixture and hammer it with a hammer. The furnace mouth is made into an inner low and the outer height is about 45°, and then brushed with graphite powder paint and tied.
