Description
Technical field
The present invention relates to stainless steel production technical fields more particularly to a kind of two phase stainless steel direct-on-line to be dissolved work
Skill.
Background technique
Marine building structure requires pitting resistance with stainless steel rebar two phase stainless steel S2205 (022Cr22Ni5Mo3N)
Height, it is now domestic to be in development phase, and also conventional solid solution craft is using offline solution treatment, i.e. collection is batched in rolling
It first cools down afterwards, then cold charge is annealed into stove heating, the energy consumption and metal consumption of offline solution treatment are big, and right in operation
Wire surface is also easy to produce wiping and scratches, and affects final product quality.
Summary of the invention
A kind of simple process, cost are provided it is an object of the invention to overcome the deficiencies in the prior art described above place
Low, energy saving resources two phase stainless steel direct-on-line solid solution crafts.
The present invention realizes in the following way:
Two phase stainless steel direct-on-line solid solution craft, it is characterised in that: specific as follows: by the height after Laying head batches
Warm wire rod is directly sent into heat-treatment furnace annealing, and the laying temperature of red steel is 880~950 DEG C, and Laying head is to having 15 between heat-treatment furnace
The insulating roller way of rice, red steel complete accumulation in insulating roller way, and stackeding speed is 180~280kg/m, are then sent into heat treatment
Furnace is heat-treated 45 meters of furnace superintendent, furnace rolls road 4.8~6cm/s of linear velocity, and in-furnace temperature is controlled at 1000~1100 DEG C, out at heat
Red steel is in spray solution device through upper and lower cool water shower quenching solution, 4.5~5kg/cm of hydraulic pressure after reason furnace2, above and below flow
280~300m3/ h enters cold scattering roller-way collection volume by the wire rod after spray quenching solution heat treatment, sampling, is packaged.
The beneficial effects of the present invention are: 1, energy-saving and emission-reduction: 30 cubic metre/ton steel of natural gas can be saved；2, metal is reduced
Consumption: due to being not required to reheating, metal amount of oxidation about 1% can be reduced；3, offline solid solution process is eliminated, reduces and operated
The wiping of wire surface is scratched in journey, improves final product quality.
Specific embodiment
The specific embodiment of the invention is now described in detail:
A kind of two phase stainless steel direct-on-line solid solution craft, it is specific as follows: by the high temperature wire rod after Laying head batches
It is directly sent into heat-treatment furnace annealing, the laying temperature of red steel is 880~950 DEG C, Laying head to the guarantor for there are 15 meters between heat-treatment furnace
Warm roller-way, red steel complete accumulation in insulating roller way, and stackeding speed is 180~280kg/m, heat-treatment furnace are then sent into, at heat
45 meters of furnace superintendent, furnace rolls road 4.8~6cm/s of linear velocity of reason, in-furnace temperature is controlled at 1000~1100 DEG C, red after heat-treatment furnace out
Steel is in spray solution device through upper and lower cool water shower quenching solution, 4.5~5kg/cm of hydraulic pressure2, flow upper and lower 280~
300m3/ h enters cold scattering roller-way collection volume by the wire rod after spray quenching solution heat treatment, sampling, is packaged.
The furnace roller road that enters of insulating roller way of the invention is divided into two absolute altitudes (difference 40mm), and two biographies are arranged in two sections of transmissions
Dynamic speed, is accumulated by the speed official post coil of wire, meets heat treatment requirements.Samming is wanted and heated with the transmission speed of furnace area adjacent segment
The furnace rolls linear velocity in area is consistent.
Heat-treatment furnace of the invention: continuous roller-hearth furnace, using heat supply above and below natural gas combustion nozzle, the smoke evacuation of furnace tail lower part, cigarette
Road sets tubular exchanger, chimney natural draught system, chief component: upper furnace body and lower furnace body.Furnace top hoisting mechanism contains
12 spiral lifts, input and output material end respectively set a lifting furnace door；Lower furnace body inlet roller way containing heating zone is (in heat-treatment furnace inlet
Equipped with inlet roller way 2, driven separately), (heat-treatment furnace furnace body is equipped with 265 furnace rolls, individually passes in heating zone furnace rolls road
Dynamic, furnace rolls bearing is using blower for air cooling).Its operation logic: continuous by specification kind setting furnace temperature and linear velocity, the coil of wire
By heat-treatment furnace, heating and samming process are completed.Heat-treatment furnace burner uses pulse combustion control system；It is arranged on flue high
Heat exchanger is imitated, warm-up combustion-supporting air realizes energy conservation；Using the equipment of practical, reliable, advanced automatically controlled instrument control, guarantee the peace of stove
Complete normal production, realizes operation automation；It is equipped with perfect Automatic thermal Control system, it is ensured that stringent air-fuel ratio and rationally
