Description

Furnace door device and melting furnace equipment

Technical Field

The utility model relates to the technical field of metal processing equipment, in particular to a furnace door device and melting furnace equipment.

Background

In the melting process of copper and copper alloy, the melting process is a process of melting copper raw material into copper liquid after heating, and a series of measures for preventing soluble gas from entering into high-temperature melt and trying to remove and purify are required in the melting process to control the quality of the cast blank and reduce defects such as air holes and shrinkage porosity. Wherein, in the melting process of the copper liquid, a covering layer with enough thickness is covered on the surface of the copper liquid, and the common material of the covering layer is charcoal which is subjected to drying treatment. In order to improve the degassing effect of the copper liquid in the melting furnace and prevent the high-temperature copper liquid from contacting the external air to generate suction oxidation, the space above the liquid level of the melting furnace (commonly called a hearth) is required to form an incomplete combustion condition of charcoal so as to form a carbon monoxide gas protection and reduction layer, thereby isolating the high-temperature copper liquid from contacting and absorbing oxygen, hydrogen and other components in the air, and carrying out reduction reaction of carbon monoxide and copper oxide or cuprous oxide in the copper liquid at the interface of the charcoal and the copper liquid, thereby realizing diffusion reaction removal of gas in the copper liquid and achieving the effect of purifying the copper liquid. For this purpose, copper and copper alloy melting furnace tops are usually provided with openable and closable furnace doors. The oven door needs to be kept closed continuously except for the operation period of adding copper raw material. After the furnace door is closed, the oxidation air entering the furnace chamber is greatly reduced, so that the covering wood charcoal achieves the effect of incomplete combustion, and the purification effect of isolating air and replacing gas in the copper liquid by the liquid level is realized.

The existing furnace door device is generally composed of a furnace door frame, a furnace cover rail connected with the furnace door frame, a furnace door cover and a horizontal moving cylinder. In order to realize the opening and closing actions of the furnace mouth, the furnace door cover needs to slide along the track under the telescopic dragging of the horizontal moving cylinder, and in order to move relatively to the furnace door frame, a certain gap needs to be formed between the furnace door cover and the furnace door frame in the vertical direction, so that the blocking and clamping faults of the furnace door cover are avoided, and the opening and closing functions of the furnace door are influenced. However, due to the existence of the gap, external air can enter the hearth from the gap, so that the covered wood charcoal on the liquid surface of the hearth accelerates combustion and oxidation to form carbon dioxide and furnace ash to be rapidly lost, and incomplete combustion cannot be maintained for a long time to form a reduction protective atmosphere in the hearth.
