Description
Technical field]
The utility model relates to the technical field of heat treatment furnace, especially a kind of production weldless steel tube combustion type heat treatment furnace.
Background technology
Weldless steel tube has hollow section, and a large amount of pipeline being used as conveyance fluid, as transfer oil, Sweet natural gas, coal gas, water and some solid materials etc.Weldless steel tube compared with the solid steel such as round steel, under identical bending resistance twisting strength, the lighter in weight of weldless steel tube; Meanwhile, weldless steel tube is also widely used in manufacturing structure part and mechanical component, and as the steel scaffolding etc. in oil drill rocker, truck drive shaft, bicycle frame and building operation, material use efficiency is high, and manufacturing process is simple and easy, and machining period reduces.
Just because of the singularity of weldless steel tube purposes, therefore, heat-treat its needs in the production process of weldless steel tube, the thermal treatment of weldless steel tube generally comprises annealing, normalizing, Quench and temper.Annealing weldless steel tube is heated to certain temperature, held for some time, and then Slow cooling gets off, and obtains the tissue close to equilibrium state, and annealing object is to reduce hardness, improves plasticity, improves processing characteristics; Eliminate internal stress, hiddenly determine steel pipe sizes, prevent distortion and ftracture; Crystal grain thinning, the mechanical property improved tissue, improve weldless steel tube.Normalizing process weldless steel tube is heated to more than " phase transformation " temperature 30 ~ 50 DEG C, held for some time, after coming out of the stove, and a kind of thermal treatment process cooled in atmosphere.Because the speed of cooling of normalizing is faster than annealing, organizing of general acquisition is comparatively thin, and the annealing of intensity, hardness ratio is higher, and particularly boi1er tube weldless steel tube, Chang Zuowei finished heat treatment, so require that finish to gauge temperature out is not less than the temperature of normalizing requirement.Quenching be weldless steel tube is heated to more than " phase transformation " temperature to fixed temperature, held for some time, a kind of thermal treatment process of then fast cooling.Quenching object is to obtain martensite, so that after proper temperature tempering, obtains required mechanical property.Tempering weldless steel tube is heated to austenite to a certain temperature below perlitic transformation temperature, after being suitably incubated, is as cold as the thermal treatment process of room temperature.Tempering object is to obtain the structure and properties needed for weldless steel tube.
But, existing most of weldless steel tube treatment furnace structure design is comparatively complicated, and thermal treatment process is single, and usual a kind of heat treatment furnace can only for the treatment of a kind of thermal treatment process, make the economic utilization rate of heat treatment furnace not high, the weldless steel tube producing different performance can not be met.
