Description

Technical Field

[0001] The utility model relates to the technical field of trolley gas furnaces, in particular to an energy-saving gas-fired trolley furnace. Background Art

[0002] The trolley-type resistance furnace is a national standard energy-saving periodic operation furnace with an ultra-energy-saving structure and a fiber structure, which can save up to 60% of electricity. It is exclusively produced with a composite high-aluminum porcelain nail set, trolley anti-collision sealing bricks, automatic sealing trolley and furnace door, and integrated connecting rails. It does not require foundation installation and can be used when placed on a horizontal ground. It is mainly used for quenching, annealing, aging of high chromium, high manganese steel castings, ductile iron, rolling mill rollers, steel balls, 45 steel, stainless steel, etc., as well as heat treatment of various mechanical parts.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing energy-saving gas-fired trolley furnaces are mostly of an integrated "door-cart" design, in which the furnace door is fixed on the top of the trolley, and personnel push the furnace door to move the trolley. In this way, during the period when the trolley is moved out to replace the workpiece, the furnace mouth is open, resulting in excessive heat loss and energy waste, which urgently needs to be improved. Therefore, we propose an energy-saving gas-fired trolley furnace. Utility Model Content
