The use and maintenance methods of trolley type resistance furnace are as follows:
① Operators must understand the structure and characteristics of electric furnace and its auxiliary equipment, add lubricating oil to reducer before use, and understand the laying of electrical circuit.
② Before switching on the power supply, be sure to carefully check whether the equipment has met the requirements of the installation and oven drying instructions.
③ If the fiber nails in the furnace are broken, they should be replaced in time. If the furnace lining is seriously damaged, they should be rebuilt in time.
④ The bottom plate of the furnace on the trolley shall not be impacted. The workpieces shall be stably placed on it and shall not be rolled or stepped. The geometric dimension of the stacked workpieces shall be within the size of the working area.

⑤嚴禁將帶有腐蝕性、揮發性、爆 炸性氣體的工件放入爐內加熱，也不能向爐內直接滴入或通入可燃性液體或氣體，以免影響加熱元件及耐火材料的壽命或發生爆 炸等意外事故。
⑤ It is strictly forbidden to put the work pieces with corrosive, volatile and explosive gases into the furnace for heating, or directly drop or pass combustible liquid or gas into the furnace, so as not to affect the service life of heating elements and refractories or cause accidents such as explosion.
⑥ Uncover the bottom plate of the furnace regularly, and purge the oxide scale and other impurities at the bottom of the bottom plate after each period of use. Especially when the bottom plate of the new furnace is put into use, the oxide scale and other impurities under the bottom plate should be cleaned immediately to prevent too much iron oxide from causing short circuit or arcing of the bottom heater. Dry river sand should be added and replaced frequently in sand seal tank.
⑦ If the heating element is broken after short-term use without serious corrosion, chs402 or chs407 high temperature stainless steel electrode can be used for welding with DC welding machine.
⑧爐門一經開啟時，設備自動切斷加熱電源，特殊工藝如切斷電源會影響工件質量，用戶應采取其它可靠的安 全措施，以確保操作人員的安 全，同時應經常檢查各電器間的聯鎖動作，以防失靈。
⑧ Once the furnace door is opened, the equipment will automatically cut off the heating power supply. Special process such as cutting off the power supply will affect the quality of the workpiece. Users should take other reliable safety measures to ensure the safety of operators. At the same time, they should often check the interlocking action between electrical appliances to prevent failure.
I explained the use of trolley type resistance furnace for you. You must pay attention to the above situations when you use it. If you don't pay attention, it will cause damage to the furnace.
