A kind of heat preservation method for stainless steel hot rolling billet

Abstract

The invention discloses a heat preservation method for a stainless steel hot continuous rolling steel billet. The method comprises the following steps that a motor in stainless steel hot continuous rolling production equipment is electrically connected with an external power supply, and the motor drives a roller to make target high-temperature steel move; an inlet and an outlet of a heater in thestainless steel hot continuous rolling production equipment are opened, and the target steel can conveniently pass through; and when heat of the target steel is low, the pressure in a shell in the stainless steel hot continuous rolling production equipment is reduced, so that a second baffle is moved to press a switch, and the switch is started to make an electric bell send out an alarm to warn workers so that the workers can operate to ensure the normal work of the stainless steel hot continuous rolling production equipment. According to the method, the moving of the target steel is facilitated through a power mechanism, the heating power of a heating mechanism can be conveniently and automatically controlled through a heat preservation mechanism, and the heat preservation and heating states of the heating mechanism can be switched. An alarm mechanism is used for conveniently giving an alarm in an abnormal state. Meanwhile, the heat preservation mechanism can be opened to finish the heat preservation state of the heating mechanism when the steel passes by.

Description

technical field [0001] The invention relates to the technical field of hot continuous rolling production equipment, in particular to a heat preservation method for stainless steel hot continuous rolling billets. Background technique [0002] The full name of continuous casting and rolling is continuous casting and continuous rolling. It is to pour liquid steel into the continuous casting machine to cast the billet, and then without cooling, keep it in the soaking furnace for a certain period of time and then directly enter the hot continuous rolling unit for rolling. Iron and steel rolling process, this process skillfully combines the two processes of casting and rolling. Compared with the traditional process of first casting a billet and then heating it in a heating furnace before rolling, it has the advantages of simplifying the process, improving working conditions, increasing The advantages of metal yield, saving energy, improving the quality of continuous casting slabs,...

AI Technical Summary

Problems solved by technology

[0003] In the common hot rolling production equipment, direct conventional heating is usually used. When the steel material is cut off, the heating equipment still continues to heat, resulting in the problem of energy waste. , when the heating function is abnormal and cannot be heated well, the alarm sound cannot be issued by itself, so that the staff cannot deal with it in time and affect the work efficiency, so a device that can solve the above problems is urgently needed
