The YIRAN natural gas shell calciner adopts the steel structure of the furnace body, which has the advantages of energy saving, environmental protection, good sealing, uniform and stable furnace temperature, accurate control, low energy consumption, uniform furnace temperature, high accuracy of PLC intelligent temperature control, simple operation and easy maintenance, etc. Shell baking furnace is mainly used for shell roasting, high chromium, high manganese steel castings, nodular cast iron, roll, steel ball, 45 steel, stainless steel and other quenching, annealing, aging and heat treatment of various mechanical parts.
1. Super energy saving structure: the heating part of YIRAN natural gas mold shell calciner consists of three parts: preheating zone, heating zone and heat preservation area, which is convenient for mold shell preheating and quickly heats up to reach baking effect. The trolley adopts impact-proof sealing brick, the furnace door adopts hand wheel and spring type automatic pressing mechanism, the automatic sealing trolley and the furnace door are integrated with rail, and can be used on the horizontal ground without foundation installation.
2. High calorific value and environmental protection use natural gas, which is a kind of energy source with high calorific value and low pollution, to provide energy, which greatly improves the heating speed, realizes the function of automatic temperature control, and is more environmentally friendly.
3. High quality of shell roasting: natural gas shell calciner adopts regenerative combustion technology, exhaust fume preheating recovery, PLC precise control of furnace temperature, small temperature difference between top and bottom of shell, high roasting quality.
4. Burners: the burner of shell calciner adopts regenerative burner, combined with the characteristics of water glass mould shell heating to avoid over burning of flame, according to the characteristics of furnace structure, direct flame burner or flat flame burner can be used. The burning loss rate of the mold shell is greatly reduced and the baking quality of the mold shell is improved.
5. Automatic temperature control system: automatic ignition, flameout alarm, automatic cut off the air source, high security, can reduce the intensity of work of operators. The control system uses a simple chain control, digital display temperature, contactor control.
