Description

The invention refers to Merannvii and can be used in the production of high-strength progayuk.

The installation of a centrifuge for the prediction of high-strength wire rods in rods by the method of thermo-mechanical treatment in the process of stable austenite j is known.

The closest to the technical essence and the achieved effect

The invention according to the invention, includes an unwinding device, a correct head, a heating unit, a deformation unit, consisting of a die installed in the housing of the core, a step;

a device consisting of a pipe, coaxially with a deformation, installed behind it and connected with the cooling bone of the bone with a triple, and a zero drum

However, in such installations, the air gap ayujHoro gap between the node of the center of the displacement and the quenching device prvsigaig to the cliffs of the provopok in the place of its release pz poroks, which causes a decrease in the production of the shield.

The purpose of the invention is to increase the processing speed and increase the reliability of the process.

The aosgigues chain supplied is due to the fact that the interchangeable choke of the coarse quenching device, through which the heating system is inserted, is inserted into the casing. The insertion of a replaceable choke allows one to increase the speed of movement of the circulating fluid directly behind the ceporification zone and, consequently, to increase the heat transfer coefficient from apoeonoKVf to the cooling fluid.

Inside (Gg1Iy diameter of the replaceable choke depends on the diameter of the box and is determined by the extrapyric ratio.

To facilitate refueling ;; The thermostats have internal gas-guiding collars and cones with cones directed to: to the side of the heated wirewire. When the heated wire passes through the uzep deformation and the quenching device 6, it is crimped to degree and full hardened. After tempering in the injector 7, the wire is wound on the drum 8.
