Between two supporting bases, the guide roller two ends were set with the square steel plunger about described guide support was located at, and square steel plunger and guide roller constitute an integral body,
Corresponding to described square steel plunger, two supporting base centers with matching are provided with square slot, the square steel plunger at guide roller two ends inserts in this square slot, this square slot width is greater than the width of square steel plunger, and patching between square steel plunger and the square slot is connected to loose fit, make guide roller can with the flexural deformation easy on and off of the steel tubes on the rollgang float and about move freely, make the steel tubes adjusting position automatically on the rollgang, correctly enter jet cooling quenching machine.
Described guiding dash assembly has many, its quantity is consistent with the steel tubes quantity on the rollgang, many guiding dash inter-module spacers are contained on the guide roller, corresponding about the position of every guiding dash assembly steel tubes on the position on the guide roller and rollgang, every guiding dash assembly comprises dash cover and guiding baffle ring, empty being enclosed within on the guide roller of corresponding position of described dash cover, the diameter of dash cover is greater than the diameter of guide roller, can make the dash cover have the floating seal effect like this, described guiding baffle ring has two, be clamped in the left and right sides of dash cover, and fixedly connected with guide roller
Guiding dash assembly on described guide roller, the guide roller, guide roller two ends square steel plunger and constitute the guiding mechanism of steel tubes with two supporting bases that the square steel plunger matches, guiding dash assembly then constitutes the first road baffle device for water of steel tubes.
Described shower cooler is arranged on the rollgang periphery of guide roller rear side, water eliminator is arranged on the shower cooler front side, water eliminator has many, its quantity is consistent with the steel tubes quantity on the rollgang, and the position of its steel tubes on the position of shower cooler front side and rollgang is corresponding.Many water eliminators constitute the second road baffle device for water of steel tubes.
The present invention has following characteristics:
1, after the widely used continous way steel pipe of cold-drawn tube mill annealing furnace installs the present invention additional, can solve the quenching quenching-and-tempering process problem of steel tubes, enlarged the thermal treatment process scope of continous way steel pipe annealing furnace, enlarged the steel pipe's production variety range, and keeping original various function constant, investment cost is few.
2, the guiding mechanism of steel tubes adopts plug in construction, loading and unloading rapidly, and can float with the flexural deformation easy on and off of steel tubes and about move freely, have very strong free adjustment function.
3, use during shower cooling tap water just have very strong cooling power (greater than 1000 ℃/Min) can satisfy the quenching of steel tubes, quenching-and-tempering process requirement.Because do not use salt solution, thereby do not have corrodibility, envrionment conditions is good.
4, the steel tubes jet cooling quenching machine requires its water yield big for finishing quench cooled, speed of cooling 〉=1000 ℃/Min.Yu Shuihui behind the shower cooling enters in the stove with the steel tubes gap.Design two road baffle device for water, the first road baffle device for water can make the surplus water of steel tubes end face all be sealed in outside the guide roller for this reason.The second road baffle device for water can stop effectively that Yu Shui enters in road, the back stove, has both guaranteed the technological effect that quenches, and has guaranteed the work-ing life of back road stove again.
