Yiran Natural GasTrolley type mold shell roasting furnaceThe equipment is suitable for mold shell roasting in the casting industry, with the advantages of high yield and stable quality. The entire set of equipment includes a roasting furnace body and inlet and outlet trolleys. The furnace lining is made of refractory bricks and is suitable for use in small and medium-sized casting plants. It can be used for high-temperature roasting of sand mold shells and sintering of gypsum wax molds, and can meet the roasting requirements of water glass adhesives and silica sol adhesives respectively. In continuous production, it is suitable for use in small and medium-sized casting plants.

The Yiran natural gas trolley type mold shell roasting furnace is mainly composed of furnace body, furnace lining, furnace door, trolley, combustion system, smoke exhaust system, sealing, temperature control and recording, and other main components. It has the advantages of low energy consumption, uniform temperature, environmental purification, and convenient maintenance. The natural gas trolley type mold shell roasting furnace is an advanced energy-saving periodic operation furnace with a super energy-saving structure. The trolley adopts anti-collision sealing bricks, and the furnace door adopts a handwheel and spring type automatic clamping mechanism. The automatic sealing trolley and furnace door are integrated with rails and do not require basic installation. They can be used on a horizontal ground. Mainly used for shell roasting, high chromium, high manganese steel castings, ductile iron, rolling mills, steel balls, 45 steel, stainless steel and other quenching, annealing, aging, as well as heat treatment of various mechanical parts. The Yiran trolley type mold shell roasting furnace has the following characteristics:

1. The furnace body skeleton of the gas trolley type mold shell roasting furnace is composed of various large and medium-sized steel sections welded on site, and the outer shell sealing plate is made of color steel plate, which is overall beautiful and sturdy.

2. The furnace lining adopts mullite refractory full fiber insulation structure, which is energy-saving and environmentally friendly.

3. The framework of the gas mold shell roasting furnace is composed of various large I-beams, channel steels, angle steels, and thick steel plates welded together. The trolley transmission adopts a combination of electric motor and worm gear reducer to drive the front active wheel transmission through a chain. The refractory masonry of the trolley adopts high alumina shaped brick structure, which has good sealing effect with the furnace body and high compressive strength. The sealing between the trolley and the furnace body adopts a soft contact method, and a labyrinth type sand sealing groove and sand sealing knife sealing device are installed at the lower part of the trolley.

4. The furnace door adopts a side opening design, which is simple and convenient, and the sealing adopts a handwheel compression mechanism.

5. The Yiran gas trolley type mold shell roasting furnace adopts a wall heat storage combustion system, with dozens of small burners installed on each side of the furnace. Multiple burners with small heat flux are used to circulate back and forth in the furnace to ensure uniform furnace temperature. The burner adopts automatic ignition and instrument control.

6. The flue gas waste heat recovery system fully utilizes the flue gas waste heat to preheat the combustion air, with high thermal energy utilization rate, low energy consumption, low nitrogen oxide emissions, and energy conservation and environmental protection.

7. The control system of the trolley type mold shell roasting furnace adopts a chain control device, with a digital display indicating temperature, contactor control, visual operation, and simple operation and easy maintenance.
