Description
Technical field
The utility model relates to a kind of structure, especially relates to a kind of heater structure based on improving heat insulation effect, belongs to mechanical field.
Background technology
Heating refers to that thermal source passes to heat energy the process that makes its heating compared with cold object.According to the acquisition of heat energy, can be divided into directly and two classes indirectly.Direct heat source heating is that heat energy is directly added on to material, as flue gas heating, current flow heats and solar radiant energy heating etc.Thermal source heating is thermophore in the middle of the heat energy of above-mentioned direct heat source is added on to indirectly, then by middle thermophore, heat energy is passed to material again, as Steam Heating, hot water heating, mineral oil heating etc.In metallurgical industry, heating furnace refers to traditionally METAL HEATING PROCESS to the industrial furnace that is rolled into forging temperature, includes continuous furnace and chamber-type heating furnace etc.In metallurgical industry, heating furnace refers to traditionally METAL HEATING PROCESS to the industrial furnace that is rolled into forging temperature, includes continuous furnace and chamber-type heating furnace etc.Heating furnace used for metal thermal treatment is separately called heat-treatment furnace.Before breaking down, heat steel ingot or make the uniform stove of steel ingot internal temperature be called soaking pit.In the broadest sense, heating furnace also comprises soaking pit and heat-treatment furnace.In broad terms, comprise the continuous furnaces such as steel-pushing type stove, walking beam furnace, rotary hearth furnace, divided chamber stove, but often refer to traditionally steel-pushing type stove.Continuous furnace is most for heating of metal material base before rolling, and minority is for forging and heat treatment.Main feature is: material base rhythm according to rolling in stove moves continuously, and furnace gas is also continuous-flow in stove; Ordinary circumstance, in the case of cross dimensions, kind and the output of furnace charge is constant, the temperature of metal charge temporal evolution and only changing along furnace length not substantially in the temperature of stove each several part and stove.
By furnace, burner hearth is divided into preheating section, bringing-up section and soaking zone along its length; Feed end furnace temperature is lower is preheating section, its role is to utilize furnace gas heat, to improve the thermal efficiency of stove.Bringing-up section is main for hot arc, and furnace gas temperature is higher, is beneficial to realize Fast Heating.Soaking zone is positioned at discharge end, and furnace gas temperature and metal charge temperature difference are very little, and the section temperature of material base of ensureing to come out of the stove is even.Only have preheating section and bringing-up section for the stove that heats light section material base.Also press traditionally the heat supply belt division stove section that burner is installed in stove, according to the number of heat supply belt, stove is called to one-part form, two-period form, down to five-part form, six segmentations etc.50～sixties, because mill capacity strengthens, and the length of steel-pushing type stove be subject to pushing away the restriction of steel length can not be oversize, so start to increase heat supply belt at feed end, cancel the preheating section of not heat supply, to improve the productivity ratio of unit hearth area.With this stove heating slab, the yield per unit area of furnace bottom reaches 900～1000 kilograms/(rice
2time), hear rate is about (0.5～0.65) × 10
6kilocalorie/ton.Since the seventies, due to energy-conservation needs, again because emerging walking beam furnace allows to increase furnace length, so set up again the preheating section of not heat supply, best furnace bottom yield per unit area is at 600～650 kilograms/(rice
2time), hear rate is about (0.3～0.5) × 10
6kilocalorie/ton.In METAL HEATING PROCESS, need to obtain high temperature, the heater of Electric heating can obtain this high temperature, is the loss that causes energy but high temperature is dispersed into extraneous one, and the 2nd, operating personnel are damaged, therefore need to improve the hermetically-sealed construction of heater.
