Example Embodiment

[0020] It can be known from the background technology that in the process of opening and closing the lid of the melting furnace in the prior art, impurities on the main body of the melting furnace are brought into the melting furnace.

[0021] The analysis found that the cover of the existing smelting furnace is directly fixed on the main body of the smelting furnace. The edge of the furnace cover is provided with push rods. By pushing the push rods with both hands, the furnace cover slides left and right relative to the surface of the main body of the melting furnace. During the opening and closing process, it is always in contact with the main body of the smelting furnace, which will cause scratches during the sliding opening and closing process, which will bring impurities on the surface of the furnace body into the smelting furnace, thereby affecting the purity of the smelting. In order to solve the above problems, the present invention provides a smelting furnace, including a...

Abstract

The invention discloses a smelting furnace. The smelting furnace comprises a smelting furnace body provided with an opening, a furnace cover used for closing the opening and a hydraulic driving mechanism. The hydraulic driving mechanism is connected with the furnace cover to control opening and closing of the furnace cover by converting hydraulic energy of the hydraulic driving mechanism to mechanical energy. In the process that the hydraulic driving mechanism controls the furnace cover to be opened or closed, the furnace cover is made to directly get away from the smelting furnace body and cannot make contact with or scratch the smelting furnace body. The possibility that impurities on the smelting furnace body are taken into the smelting furnace when the furnace cover is opened or closedis reduced. Moreover, the furnace cover can be opened more conveniently and quickly through control of the hydraulic driving mechanism.

Description

technical field [0001] The invention relates to the field of smelting, in particular to a smelting furnace. Background technique [0002] Ultra-high-purity aluminum refers to aluminum and aluminum alloys with a purity greater than 99.99%. When smelting ultra-high-purity aluminum, the ultra-high-purity aluminum must be put into the melting furnace for heating and melting; during the melting process, the furnace cover needs to be kept warm , but in the process of melting ultra-high-purity aluminum, it is necessary to open the furnace cover frequently for quenching and tempering, and the furnace cover needs to be opened and closed repeatedly. Therefore, it is necessary to avoid falling impurities in the furnace due to the opening of the furnace cover, so as to avoid affecting the purity of the ultra-high-purity aluminum. [0003] In the prior art, the furnace cover is fixedly arranged on the smelting furnace. It is necessary to push the furnace cover to rotate so that the furn...
