Description

Изобретение относитс к прокатному производству и термической обработке металлов и может быть использовано дл получени полос из углеродистых и легированных сталей со структурой сфероидизированного (зернистого) перлита.The invention relates to rolling production and heat treatment of metals and can be used to produce strips of carbon and alloy steels with the structure of spheroidized (granular) perlite.
Целью изобретени вл етс сни- жейие энергозатрат при обработке.The aim of the invention is to reduce energy consumption during processing.
Пример 1. Ленту из высокоуглеродистой стали марки У8А толщиной 2,2 мм со структурой грубо- пластинчатого перлита прокатывают при 700 С на лентопрокатном стане за один проход. Суммарное обжатие, рассчитанное по предложенной формуле , составл ет 0,5. Структура гото- ,,вой ленты после обработки по данном режиму представл ет собой зернистый перлит 4-7 баллов.Example 1. A tape of high carbon steel grade U8A with a thickness of 2.2 mm with the structure of coarse-lamellar perlite is rolled at 700 C in a tape-rolling mill in one pass. The total reduction calculated by the proposed formula is 0.5. The structure of the ready-made tape after processing in this mode is a granular perlite 4-7 points.
Обработка с су1« арным обжатием 0,3, т.е. меньншм расчетного, приводит к структуре, состо щей из смеси зернистого и пластинчатого перлита.Treatment with cy1 "ary compression 0.3, i.e. small settlement, leads to a structure consisting of a mixture of granular and lamellar pearlite.
Обработка с суммарным обжатием 0,7, т.е. по известному способу определ ет 100% зернистую структуру перлита, но сопровождаетс перерасходом 170 кВт/ч энергозатрат на 1 т проката.Processing with a total compression of 0.7, i.e. according to a known method, it determines the 100% granular structure of perlite, but it is accompanied by an over expenditure of 170 kW / h of energy consumption per 1 ton of rolled metal.

Пример 2. Ленту из легированной стали марки Х6ВФ толщиной 3,5 мм со структурой грубопластинча- того перлита прокатывают при 750 С 5 на лентопрокатном стане 300 за два прохода с промежуточным подогревом между проходами. Суммарное обжатие составл ет при этом 0,35 в соответствии с расчетом по предложенной 10 формуле. Структура готовой ленты после обработки по данному режиму представл ет зернистый перлит 5-7 баллов.Example 2. A 3.5 mm thick X6VF alloy steel tape with a coarse perlite structure is rolled at 750 C 5 on a tape rolling mill 300 in two passes with intermediate heating between passes. The total reduction is 0.35 in accordance with the calculation according to the proposed 10 formula. The structure of the finished tape after processing in this mode is granular perlite 5-7 points.
fS Обработка с суммарным обжатием 0,24 приводит к структуре, состо щей из смеси зернистого и пластинчатого перлита.fS Treatment with a total reduction of 0.24 results in a structure consisting of a mixture of granular and lamellar perlite.
