Abstract：The hot delivery and direct rolling of hot billets during continuous casting is a new technology for the production of continuous casting - bar steel rolling. Hot continuous casting billet is delivered directly into the rolling production line for rolling through the hot delivery roller without passing through the heating furnace. The technology is not easy for operation. Basing on the experience of foreign factories， we have conducted a series of improvements and experiments on the process of continuous casting - hot delivery - steel rolling， and have achieved below achievements： (1) success in operation of hot delivery and direct rolling of the hot billets during continuous casting proves the feasibility of the technology； (2) a stable mass production of consecutive has realized for three years； (3) an annual benefit of over 50 million has received； (4) a set of practicable and effective management methods of production and technology control has concluded. Discussions and introductions have made in the part of electrical automation specialty for hot delivery and direct rolling of the hot billets during continuous casting on a series of core technologies and key technical measures， including the continuous casting control， the hot billets cutting length control， hot billets weighing， collecting， eliminate and moving control， hot delivery roller and delivery control， head heating technology during hot delivery， entrance control before rough mill， the main rolling area control of the production line， the core technology of electrical automation software and the hardware configuration.
