Description

Technical Field

[0001] The utility model relates to the technical field of gas-heated tin-melting furnaces, and more specifically, to a gas-heated tin-melting furnace. Background Art

[0002] In the existing technology, gas-heated tin melting furnaces usually use gas as a heat source to achieve a rapid heating effect. However, there are some design defects in this type of tin melting furnace, especially in the structural problems between the furnace body and the heating shell. Since the fitting area between the two parts is small, sufficient heat exchange cannot be achieved, so a considerable amount of heat will be lost through these areas that are not fully fitted during the heating process. This heat loss not only reduces the heating efficiency of the furnace, but also may lead to energy waste and increase operating costs.

[0003] In addition, there are also design problems with the gas pipes of the tin melting furnace, especially in terms of installation and maintenance. In existing furnace models, the fixing and removal process of the gas pipes is complicated and cumbersome, usually requiring professional tools and certain technical operations, which brings inconvenience to daily maintenance. If the gas pipes cannot be quickly and safely fixed or removed, it will not only affect the maintenance efficiency of the equipment, but may also cause gas leakage in case of improper operation, increasing safety risks.
