well type heating furnace equipment

The furnace shell of well type heating furnace is assembled and welded by section steel and high quality steel plate, which can realize the sealing between furnace cover and furnace body, and set smoke exhaust device on the upper part of furnace shell.

The furnace cover with heat preservation function of well type heating furnace can cooperate with furnace tank airtight to ensure good sealing of furnace atmosphere. The lower part of the shaft heating furnace is equipped with a wind collecting cover, which can cooperate with the draft tube. The circulation fan is installed in the furnace cover to enhance the uniformity of temperature and atmosphere. The lifting and rotation of the furnace cover of the well type heating furnace is a rotary arm type axis transmission mechanism, and the furnace cover is equipped with a guiding device for lifting and guiding. The lifting and rotation of the furnace cover is a rotary arm type axis transmission mechanism.. The furnace cover is located on the flange ceramic fiber braided rope on the furnace mouth. Under the heat preservation package of the cover body, a wind guide cover matched with the draft tube is installed, and the wind guide cover is hung on the flange type panel of the cover body through a plurality of suspenders. The automatic lifting and walking structure of furnace cover runs smoothly and its service life is not less than 5 years.

The furnace bottom lining of well type heating furnace is made of light clay brick and heavy anti carburizing masonry. The furnace wall lining is of composite lining structure. The refractory layer is made of light clay brick, and the insulation layer is made of ceramic fiber cotton or clay brick. Each layer is optimized. Stainless steel hook is prefabricated in the refractory layer of well type heating furnace, which is used for the installation of resistance wire and belt.

The heating device is evenly arranged around the lining wall, and the well type heating furnace is made of high-temperature electric heating alloy belt, and is distributed in each heating area. The installation method ensures heating uniformity, service life and high reliability, and is convenient for installation and maintenance. Each heating zone of the furnace is equipped with thermocouple for temperature measurement and over temperature alarm.

The reheating furnace of well type heating furnace is mainly composed of furnace shell, furnace lining, heating elements, furnace pot, air guide tube, furnace cover, lifting and rotating (or translation) system of furnace cover, circulating fan, etc. The heating system can effectively control the temperature and ensure the temperature uniformity of the effective heating zone.
