Hot rolling and cold rolling are two vital forming processes for steel plates and profiles, which significantly alter steel’s internal microstructure and mechanical properties. What are their essential differences? Steel production mainly relies on hot rolling. Cold rolling is only adopted to manufacture precise-sized products including small-sized section steel and
Question 1: Problems & Countermeasures of Grooveless Rolling (1) Instability of rolled pieces Without constraint from groove side walls in grooveless rolling, rolled stock is prone to square distortion and offset. Larger reduction leads to worse stability and interruptions to rolling. Solutions: Install double-row rolling guides at mill entry; equip
Introduction The pusher-type heating furnace is a critical piece of equipment in the steel rolling industry, designed to heat steel billets to the required temperature before they enter the rolling mill. This guide provides a detailed, factual overview of the pusher furnace based on standard training materials, covering its main
