There are many forms of heat preservation in glass annealing furnace. according to the classification of heat-treated glass, the common forms are as follows: ① heat preservation basis of mesh belt type glass annealing furnace It is mainly used for primary annealing of daily glass and lighting glass such as glass bottle, glass utensil, etc., and secondary stress relief annealing after re - processing. the total length of the furnace body is 6 - 40m, and the maximum service temperature is 650 ℃.

Coke can cover as an accessory equipment of coke dry quenching hoist, its main function is to prevent the red coke in the coke can high temperature damage to the hoist and prevent dust float in the sky. Which mainly comprises a coke pot cover body, a sealing plate, a heat insulation material and a guide device of the coke pot cover. The main forms of coke pot cover are square coke pot cover and round coke pot cover.

Thin slab continuous casting and rolling process is a relatively compact and efficient new furnace technology introduced in recent years. The method comprises the following steps: carrying out heat preservation or local heating on 40 - 70 mm thick slab cast by a continuous casting machine, sending the slab to a strip steel hot continuous rolling mill, and directly rolling the slab into 1.0 - 2.3 mm thick strip steel.

Masteel ring quenching furnace for continuous operation furnace, fuel using mixed gas, burner in staggered arrangement on the inner and outer ring wall, normal furnace temperature is 1000 ~ 1100 ℃, weak reducing atmosphere, micro positive pressure operation. Consideration before transformation: comparison between heavy traditional lining and light ceramic fiber lining Traditional lining structure: refractory brick and heavy castable structure

Carbon baking furnace is a kind of thermal equipment which can indirectly heat various carbon products after high pressure forming according to the specified baking temperature under the condition of isolating air, so as to improve the electrical and thermal conductivity of the products and improve the strength of the products.

Electrolytic aluminum is aluminum obtained by electrolysis. Cryolite - alumina molten salt electrolysis is used in modern electrolytic aluminum industry. Molten cryolite is a solvent, aluminum oxide is use as solute, carbon body is used as anode, aluminum liquid is use as cathode, strong direct current is introduced, and then electrochemical reaction is carried out on two poles in an electrolytic bath at 950 - 970 deg c, so that electrolysis is carry out.

Trolley furnace belongs to gap type variable temperature furnace, which is mainly used for steel ingot heating or workpiece heat treatment before forging, so its furnace type can be divided into trolley type heating furnace and trolley type heat treatment furnace. The furnace consists of a hearth, a movable trolley and a furnace door.

Bell - type furnace is used for bright annealing and heat treatment of workpiece equipment, belongs to the intermittent variable temperature furnace, furnace temperature in 650 ~ 1100 ℃, according to the provisions of the heating system changes with time. According to the loading of bell-type furnace, the furnace is divided into two categories: square bell-type furnace and circular bell-type furnace. The heat source of bell-type furnace is mostly gas, followed by electricity and light oil. Generally consist of an outer cov, an inner cover and a furnace platform, wherein that combustion device is mostly arranged on the out cover, the outer cover is provided with a heat insulation layer, and a workpiece is generally arranged in the inner cover for heating and cooling.

Well cementite furnace is a new type of energy-saving periodic operation type heat treatment furnace, which is mainly used for gas carburizing of steel parts and is suitable for heat treatment of rod and long shaft parts. The structure of the well furnace is as follows: the furnace body is a cylindrical deep well, and the workpiece is vertically loaded into the furnace by a special crane for heating.

Thermal power plants is the use of coal, oil, natural gas or other fuel chemical energy to produce electricity. The generator set of thermal power plant is composed of boiler, steam turbine and generator and many auxiliary equipment pipes.
