The manufacturer of industrial furnace insulation board believes that the forging workshop includes cupola, induction furnace, resistance furnace, electric arc furnace, vacuum furnace, open hearth furnace, crucible furnace, etc. There are sand drying furnace, ferroalloy drying furnace, casting annealing furnace, etc. In the forging workshop, there are various heating furnaces for heating steel ingots or billets before forging and heat treatment furnaces for stress after forging. In the metal heat treatment workshop, there are various heat treatment furnaces for annealing, normalizing, quenching and tempering, and the mechanical properties of the workpiece; The welding workshop has pre-welding preheating furnace and post-welding tempering furnace for welding parts; There is a heating furnace for sintered metal in the powder metallurgy workshop.

The insulation board manufacturer of industrial furnace believes that industrial furnaces in other industries, such as metal smelting furnace, ore sintering furnace and coking furnace in metallurgical industry; Distillation furnace and cracking furnace of petroleum industry; Industrial gas generator; Cement kiln, glass melting and glass annealing furnace in silicate industry; Industrial oven, etc.

Adjusting the fuel structure of industrial furnaces: Although coal is still the main energy in China at the proportion stage, it not only pollutes seriously, but also is not conducive to the implementation of high-temperature air combustion technology. Therefore, replacing coal and other solid fuels with oil and gas is the strategic direction of energy-saving development of industrial furnaces in China.

The insulation board manufacturer of the industrial furnace believes that the industrial furnace has further developed and improved the oxygen-enriched combustion technology. Improving and popularizing high temperature air combustion technology is still the direction of energy saving development of industrial furnaces in the future. The technology of raising furnace temperature and making furnace temperature evenly distributed on the basis of ensuring high temperature flame and NOx control technology are the core technology and future development direction of promoting oxygen-enriched combustion. At the same time, CO2 emission reduction and storage will become an important research hotspot. Waste heat recovery and full utilization of low calorific value fuel are the energy-saving development of industrial furnaces.

The industrial furnace insulation board manufacturer believes that the industrial furnace masonry will be integrated and lightweight. With the development of amorphous refractories, monolithic casting and lightweight structures will be developed more widely. Using new refractory materials and replacing refractory bricks with high-temperature resistant ceramics and ceramic fibers can make the furnace temperature rise rapidly and reduce heat loss.

Energy conservation and environmental protection of industrial furnace: the insulation board manufacturer of industrial furnace believes that pollution control should be carried out and efforts should be made to reduce or harmful exhaust gas and smoke emissions. For China, energy conservation is one of the important environmental protection measures.

The industrial furnace insulation board manufacturer believes that there are various heating furnaces in the forging workshop for heating steel ingots or billets before forging, and heat treatment furnaces for stress after forging. In the metal heat treatment workshop, there are various heat treatment furnaces for annealing, normalizing, quenching and tempering to improve the mechanical properties of the workpiece. The welding workshop has pre-welding preheating furnace and post-welding tempering furnace. There is a heating furnace for sintered metal in the powder metallurgy workshop. Industrial furnaces are also widely used in other industries, such as metal smelting furnaces, ore sintering furnaces, coke ovens, etc. in the metallurgical industry. Distillation furnace and cracking furnace of petroleum industry; Industrial gas generator; Cement kiln, glass melting furnace and annealing furnace in silicate industry; Oven for food industry, etc.
