Description

Height-increasing parts for intermediate frequency furnaces for casting and smelting

technical field

The utility model belongs to the technical field of intermediate frequency furnace appliances for casting and smelting, in particular to a height-increasing piece for intermediate frequency furnaces for casting and smelting.

Background technique

At present, in the foundry manufacturing process in our country, because the power of the intermediate frequency furnace is continuously adjustable, the power density is high, and the operation is convenient, it is beneficial to realize rapid melting, without contact with coke, and without blower, and the smoke and dust are less. Because the company's intermediate frequency furnace can melt up to 5 tons of molten iron at a time, it cannot be suitable for products of 6 tons to 9 tons. Because the furnace mouth of the 5-ton bag is too low during the smelting process, it is easy to overflow or splash out from the furnace mouth when molten iron boils in the smelting process and there are unsafe factors. The loss of molten iron is serious. Serious waste of cost, restricting the development of cast iron production capacity.

Contents of the invention

The purpose of this utility model is to solve the technical problems described above, to provide a casting that reduces the unsafe factors caused by boiling or splashing of molten iron, improves the working efficiency of workers, reduces iron consumption, and can effectively optimize industrial structural analysis. The technical scheme of the height-increasing parts of the intermediate frequency furnace for smelting is as follows:

The height-increasing part of the intermediate frequency furnace for casting and smelting is characterized in that the height-increasing part of the intermediate-frequency furnace for casting and smelting is an annular body, and the height-increasing part includes an inner ring and a side ring, and the side part of the side ring is uniform There are several fixing bolt installation cavities in the part, the bottom of the fixing bolt installation cavities extend into the inner ring, the fixing bolt installation cavities are provided with installation holes, and the height-increasing parts are locked in the furnace through the installation holes. verbal.

The height-increasing part of the intermediate frequency furnace for casting and smelting provided by the utility model, the height-increasing part is an annular body, which can better adapt to the furnace mouth. The separate setting of the inner ring and the side ring can make the inner ring and the side ring use different materials, and the material can be selected according to the different use requirements and environments, so that the heightening parts can be used for a longer time, and at the same time, the cost can be saved. The fixing bolt is installed in the cavity so that the installation hole is arranged inside and is not damaged.

The beneficial effects of the utility model are: reducing the unsafe factors caused by the boiling or splashing of molten iron, improving the working efficiency of workers, reducing iron consumption, and effectively optimizing industrial structural analysis.

detailed description

Below in conjunction with Fig. 1 concrete description embodiment:

As shown in Figure 1, the heightening piece of the intermediate frequency furnace for casting and smelting, the heightening piece of the intermediate frequency furnace for casting and smelting is an annular body, and the heightening piece includes an inner ring 1 and a side ring 2, and the side ring The uniform part of the side part of 2 has several fixing bolt installation cavities 3, and the bottom end of the fixing bolt installation cavities 3 extends into the inner ring 1, and the fixing bolt installation cavities 3 are provided with installation holes 4, so The height-increasing piece mentioned above is locked on the furnace mouth of the intermediate frequency furnace through the installation hole.

The inner ring can be made of high temperature resistant material.

The heightened intermediate frequency furnace is suitable for the processing of castings from 5 tons to 8 tons, which reduces the unsafe factors caused by boiling or splashing of molten iron, improves the working efficiency of workers, and reduces iron consumption. After repeated practice and use, the heightened furnace If the mouth and the standard furnace mouth are at the same temperature, frequency, and working method, the amount of molten iron will be increased, and the quality of the molten iron will not be affected during the process, nor will it affect the quality of the casting. To maximize the utilization of electric energy.
