Tin melting furnace for producing tin ingots

Abstract

The invention discloses a tin melting furnace for producing tin ingots and belongs to the technical field of tin ingot production equipment. A lining is arranged in a furnace body, electric heaters are arranged between the lining and the furnace body, the electric heaters are connected with an external power supply through wires, a feeding opening and a discharging opening are arranged in the furnace body, a supporting rod is arranged on the lining, hydraulic pumps are arranged in the supporting rod, push plates are arranged outside the supporting rod, the hydraulic pumps are connected with the push plates through hydraulic rods, the amount of the push plates is two or more than two, movable plates are arranged at the upper ends of the push plates, the movable plates are connected with thepush plates through rotating shafts, pushers are arranged on the push plates, the pushers are connected with the movable plates, movable angles of the movable plates are 30 to 45 degrees, and a thermal-insulation layer is arranged outside the furnace body. The movable plates are driven by the pushers to move fro and back, so that the melting effect is improved; the thermal-insulation layer is used for thermal insulation, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of tin ingot production equipment and relates to a tin melting furnace for producing tin ingots. Background technique [0002] Tin ingot is the product form of tin smelters and the basic raw material for all tin deep processing. Tin is a silver-white metal with soft quality and good ductility. It is also a metal with a low melting point. Its melting point is only 232°C. Therefore, as long as It can be melted with a candle flame into a liquid with good fluidity like mercury. The metal tin refined in factories is mostly made into tin ingots for transportation. To obtain practical products, tin ingots need to be processed. The first step is to melt the tin ingot. Tin can be used as a coating material. It is widely used in food, machinery, electrical appliances, automobiles, aerospace and other industrial sectors. In the production of float glass, the molten glass floats on the molten glass. The surface of the ...

Problems solved by technology

[0003] Most of the existing tin melting furnaces for producing tin ingots are heated at the bottom. Because the heating of the tin melting furnace is not uniform enough, it is easy to make the tin solution on the edge of the tin melting furnace solidify. Although the melting point of tin is low, it will The heat loss is still quite large, and the energy consumption is high, which is far from meeting the current people's requirements for this product
