A metallurgical heating furnace

Abstract

The invention provides a metallurgy heating furnace. The metallurgy heating furnace is high in energy utilization rate and long in service life. The metallurgy heating furnace comprises a furnace body, wherein a plurality of high-temperature-resistant infrared radiant panels are detachably installed on the inner wall of a hearth of the furnace body, an infrared radiation layer is arranged on the face, facing towards the interior of the hearth, of each high-temperature-resistant infrared radiant panel, and a thermal insulation layer is arranged on the face, facing towards the wall of the hearth, of each high-temperature-resistant infrared radiant panel; the infrared radiation layers are made of cordierite slabstone or silicon carbide plates, and the thermal insulation layers are ceramic fiber blankets. Due to the fact that the high-temperature-resistant infrared radiant panels with the thermal insulation layers are installed on the inner wall of the kiln furnace, absorbed energy can be evenly radiated to a product to be sintered. The thermal insulation layers are arranged on the back sides of the radiant panels, heat is prevented from being transmitted to the furnace wall, and thus energy can be transmitted to the product to be sintered through radiation. The service life of the kiln furnace is prolonged due to the high-temperature-resistant infrared radiant panels, economic benefits are improved, the requirement for the quality level of refractory materials of the wall of the kiln furnace can be reduced, and the furnace construction cost is reduced.

Description

technical field [0001] The invention relates to a metallurgical heating furnace. Background technique [0002] my country's industrial kilns and industrial boilers are the main body of energy consumption, and industrial kilns generally have low thermal efficiency and relatively large energy waste. In view of the low effective utilization rate of energy and relatively large energy waste in industrial kilns, the main energy-saving measures generally adopted at home and abroad are: (1) use light-weight thermal insulation materials with good thermal insulation effects as much as possible; (2) Adopt far-infrared energy-saving paint spraying technology; (3) waste heat recovery and utilization of flue gas; (4) energy-saving technology of black body radiation elements. [0003] The traditional way is to use light materials with small heat capacity and insulation materials to build furnaces to reduce heat storage and heat dissipation losses. This energy-saving method only "blocks" ...

AI Technical Summary

Problems solved by technology

[0006] The fundamental weakness of far-infrared coating technology is that the coating is easy to age. During actual use, it will continue to pulverize and fall off or be eroded by airflow. The thermal infrared emissivity will gradually decay, lose the infrared radiation function, and the thermal efficiency will decrease with time.
